CA 02229~33 l998-02-l3 W O 97/06758 PCT~US96/13348 IN~IJ~ liL R~-~nD~ ~G..l~L DEVICE WITH pF~T~'~ APPA~L~TUS
Background of the Invention Field of the Invention The present invention generally relates to the field of medical devices and more particularly to intraurethral blA~er control devices, and still more particularly to intraurethral bladder control devices with retA;n;ng means.
Description of the Prior Art The use of bladder control devices, often referred to as artificial sphincters, is wide spread in the field of the present invention. The use of such intraurethral valving apparatus and its general knowledge in the field of art can be evidenced by, for example, U.S. Patent Nos. 4,553,533;
4,679,546; 4,969,474; and 5,123,428.
A continuing problem found in the prior art devices is the safe and secure retention of the bladder control or valving device in the urethra. It is desirable to have the placement of the bladder control apparatus in the urethra be a nonsurgical function, and it is important not only that the device be securely retained once placed in the urethra, but also that a nonsurgical, safe and reasonably simple means of removing the device be present. Various prior art devices have not met all of these criteria.
-CA 02229~33 1998-02-13 W O 97/06758 PCT~US96/13348 Summary of the Invention The apparatus of this invention overcomes problems existent in the prior art by providing an improved intraurethral blA~e~ control device with retainer apparatus.
Broadly speaking, the apparatus of this invention comprises housing having an internal fluid flow path and valving means mounted in the fluid flow path and responsive to pressure from a patient's bladder to open and close the path to the flow of fluid from the bladder. A first retainer is mounted to the distal end of the housing and operates within the bladder to hold the bladder control apparatus within the urethra. In the preferred embodiment described herein, this first retainer comprises a leaf spring having a plurality of leaves which are compressed during placement of the bladder control device into the urethra, which leaves spring open when the distal end of the bladder control device reaches the opening into the bladder from the urethra. As used throughout this disclosure, the term "distal end" shall mean the end of a device or internal lumen which is intended to be closest to the bladder, and the term "pro~ l end~' shall mean the end of the device or lumen which is closest to the urethral labia.
The apparatus of this invention also includes a second retainer which is connected to the pro~ l end o~ the bladder control device after its plAc ~nt in the urethra, and which second retainer extends proximately out of the urethra where CA 02229~33 1998-02-13 a portion thereof wider than the urethra abuts the urethral labia.
From the above brief description it can be seen that what is provided is a bladder control apparatus which is retA i n~
in a patient's urethra by a first ret~;ning means operable within the bl~er and by a second ret~in;ng means abutting the labia of the urethra. Thus a secure and safe system is provided for an intraurethral bladder control device.
~rief DescriPtion of the Drawinqs Other objects of the present invention and many of the atte~nt advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings, in which drawings like reference numerals designate like parts throughout the figures thereof, and wherein:
Fig. 1 is a perspective view representative of the apparatus of this invention;
Fig. 2 is a sectioned plan view of the assembled apparatus of this invention;
Fig. 3 is an exploded view of the apparatus of Fig. 2;
Fig. 4 is an exploded view similar to that of Fig. 3 with an additional extender part added to the apparatus of this invention; and CA 02229~33 1998-02-13 W O 97/06758 PCT~US96/13348 Fig. 5 is a partially sectioned view representative of the urethra and blA~er of a patient with the apparatus of this invention shown as retained in the urethra of the patient.
Detailed Descri~tion of the Preferred Embo~ ts Fig. 1 discloses a perspective view of the b~ e~
control device 10 of this invention. It can be seen that the device 10 includes an upper or retainer housing 12 and a lower or full control housing 15. The distal end of housing 15 is connected to the proximal end of housing 12 such that an internal lumen within each of housings 12 and 15 (as fully depicted in each of Figs. 2, 3 and 4 of the following drawings) to combine to make one continuous fluid flow path through the device 10. A first retainer 30 is connected to the distal end of housing 12. In the preferred embodiment of Fig. 1, retainer 30 is shown as a leaf spring having a plurality of leaves, in this emboAim~nt four leaves. The tips of each of the leaves of spring 30 is provided with a generally hemispherical deposit 31 which acts as a safety device to prevent the tips of each leaf or spring 30 from damaging the internal wall of the bladder. A second retainer (not shown in Fig. 1, but present in each of the following figures of the drawings) is adapted to be connected to the 25 pro~ end 17 of housing 15 after device 10 has been placed CA 02229~33 1998-02-13 W O 97/06758 PCT~US96/13348 in the urethra of a patient and retainer 30 has opened in the bladder of the patient.
Referring now to Fig. 2, there is shown a cross-sectional plane view of the assembled apparatus of this invention comprising bladder control device 10. It can be seen that a nut 33, having a central lumen, is used to mount spring 30 within the lumen of housing 12. It can be seen that the leaves of spring or upper retainer 30 are in their uncompressed or extended position, as they would be when inside the bladder of a patient. It can also be clearly seen how safety device 31 takes the form of a hemispherical formation at the tip of each of the leaves of leaf spring or retainer 30.
Also in Fig. 2 it can be seen that within the lumen for~ed by flow control housing 15 there is mounted a valve assembly for controlling the flow of fluid through the lumen, the assembly comprising a stopper 16, a biasing means or spring 22, a first mounting ring 18 that defines the inner housing ch~her within which stopper moves, and a second spring mounting ring 24. The ring 24 is mounted within housing 15 and receives the pro~;~-l end of the bias means or spring 22. Ring 18 is mounted for rotational movement within housing 15, and has its distal movement inhibited by a ridge 13 within housing 15. Spring 22 extends through mounting ring 18 and has its distal end connected to stopper 16, which CA 02229~33 1998-02-13 WO 97/06758 PCT~US96/13348 stopper 16 is slidably mounted for ~l~v, -nt within the lumen of housing 15.
Also shown in the Fig. 2 depiction of the assembled blA~1r~r control device 10 is a second or lower retainer 35.
~et~;nPr 35 has a first portion adapted to be connected to the proximal end of housing 15, preferably by a threaded connection. Retainer 35 also has a second section which is significantly wider than either of housings 12 or lS, and thus it will be wider than the urethra after placement of device 10 within the urethral. The second portion or wider portion of retainer 35 is adapted to contact the labia.
As is apparent from the study of Fig. 2, when fluid from the bladder achieves a predeter~ined pressure, which can be pressure applied by the muscles of the patient, the normal bias' of spring 22 will be overcome and stopper 16 will slide proximately to open the valving apparatus to allow the flow of fluid from the bladder through device 10 and from the urethra as i nr1 ic~ted by the arrow. It should be noted that nut 33, ring 18, spring 22, ring 24, and retainer 35 all have internal fluid flow paths which align with the axis of the lumens of housings 12 and 15 so that the only major inhibitor of fluid flow from the bl~r~Pr through the urethra is stopper 16 when it is in place. When stopper 16 is slid proxi ~lly by the pres~ure of the bl~er fluid, the stopper 16 is sized such that fluid will flow around it within the lumen of housing 15.
CA 02229~33 1998-02-13 Referring now to Fig. 3, the apparatus of Fig. 2 is shown in exploded view. ~ere it can be seen how nut 33 is placed to hold the blA~er ret~;n;ng means or spring 30 within the lumen of housing 12. It can also be seen how housing 15 has its distal end connected to the pro~;m~l end of housing 12. It can also be seen how stopper 16 is positioned through the lumen of housing 15 to abut a narrowed inner portion of the lumen of housing 15 and how ring 18 is then slid through the pro~; -1 end 17 of the lumen of housing 15 to abut the ridge 13 in the wall of the lumen of housing 15. Spring 22 then has its upper or distal portion placed through the lumen of housing 15, through ring 18 and into connection with stopper 16. Ring 24 is then placed to receive the pro~;m-o~l end of bias means or spring 22 and is pushed through the pr~;mol end 17 of housing 15 and connected within the lumen of housing 15. Finally, after placement of the apparatus of Fig. 3 within the urethra of the patient, the second ret~;ne~ or lower retA;ner 35 is threaded into position at the pro~; m~o. 1 end 17 of housing 15.
As is apparent, when the exploded parts of Fig. 3 are assem~led, they will form the assembled device 10 as shown in Fig. 2.
Re~erring now to Fis. 4 there is sh~w~ a~o~e~ exploded view forming yet another embo~; ~nt of the apparatus of this invention. It will be apparent from Fig. 4 that all the parts of this embo~; m~nt are the same as the parts of Figs. 2 and 3 CA 02229~33 1998-02-13 WO 97/06758 PCT~US96/13348 with the exception of an extender 40 placed between ring 24 and ret~in;ng means 35. Thus when the parts of the spring valving of Figs. 2 and 3 have been properly placed through the pro~i ~1 end 17 of housing 15 and are held in place by ring 24, housing 15 is adapted to receive the distal end of ext~e~ 40, preferably by threading, and retainer 35 is then connected to the pro~i~l end of ext~n~e~ 40 instead of the pro~i--l end of housing 15. Thus the apparatus of Fig. 4 shows an emboAi -nt of the apparatus of this invention whereby the length of device 10 can be selectively changed by utilizing any one of a number of different sizes of extender 40.
Referring now to Fig. 5 there is shown a partial cross-sectional view representative of the urethra and bladder of a patient. In Fig. 5 the bladder control device 10 is shown after placement in the urethra of the patient and after whatever placement devices which were used have been removed and the urethra has undilated to closely hold and form to the outer surface of device 10. It can be seen how retainer 30 in the form of a leaf spring has opened within the bladder and how the safety devices on the tips of the leaves of spring 30 provide a safety factor to prevent puncture of the bladder wall by the tips of the leaves. Finally, it can be seen how the second or lower retainer 35 when connected to the pro~; ~D 1 end of device 10 contacts the labia of the urethra, and how device 10 is thus held within the urethra by retainer 30 and CA 02229~33 1998-02-13 W O 97/06758 PCT~US96/13348 35 acting at opposite ends of the urethra. It should be recognized that the above-described invention derives its ultimate utility when properly placed within the urethra of the patient. Various prior art methods of dilation of the urethra for placement of a device ~uch as device 10 may be known in the prior art. ~owever, it is believed that the most advantageous apparatus for such placement is fully described in co-pending U.S. application Serial No. 08/515,564, filed August 16, 1995, entitled BLADDER CONTROL INSERTION APPARATUS, owned and assigned to the assignee of this invention, and hereby incorporated by reference in this disclosure.
Having thus described the preferred ~mho~ nts of the present invention, those of skill in the art will readily appreciate other useful embo~ nts within the scope of the claims hereto att~che~.
Background of the Invention Field of the Invention The present invention generally relates to the field of medical devices and more particularly to intraurethral blA~er control devices, and still more particularly to intraurethral bladder control devices with retA;n;ng means.
Description of the Prior Art The use of bladder control devices, often referred to as artificial sphincters, is wide spread in the field of the present invention.

A first retainer is mounted to the distal end of the housing and operates within the bladder to hold the bladder control apparatus within the urethra. In the preferred embodiment described herein, this first retainer comprises a leaf spring having a plurality of leaves which are compressed during placement of the bladder control device into the urethra, which leaves spring open when the distal end of the bladder control device reaches the opening into the bladder from the urethra. As used throughout this disclosure, the term "distal end" shall mean the end of a device or internal lumen which is intended to be closest to the bladder, and the term "pro~ l end~' shall mean the end of the device or lumen which is closest to the urethral labia.

Fig. 1 is a perspective view representative of the apparatus of this invention;
Fig. 2 is a sectioned plan view of the assembled apparatus of this invention;
Fig. 3 is an exploded view of the apparatus of Fig. 2;
Fig. 4 is an exploded view similar to that of Fig. 3 with an additional extender part added to the apparatus of this invention; and CA 02229~33 1998-02-13 W O 97/06758 PCT~US96/13348 Fig. 5 is a partially sectioned view representative of the urethra and blA~er of a patient with the apparatus of this invention shown as retained in the urethra of the patient.
Detailed Descri~tion of the Preferred Embo~ ts Fig. 1 discloses a perspective view of the b~ e~
control device 10 of this invention. It can be seen that the device 10 includes an upper or retainer housing 12 and a lower or full control housing 15. The distal end of housing 15 is connected to the proximal end of housing 12 such that an internal lumen within each of housings 12 and 15 (as fully depicted in each of Figs. 2, 3 and 4 of the following drawings) to combine to make one continuous fluid flow path through the device 10. A first retainer 30 is connected to the distal end of housing 12. In the preferred embodiment of Fig. 1, retainer 30 is shown as a leaf spring having a plurality of leaves, in this emboAim~nt four leaves. The tips of each of the leaves of spring 30 is provided with a generally hemispherical deposit 31 which acts as a safety device to prevent the tips of each leaf or spring 30 from damaging the internal wall of the bladder. A second retainer (not shown in Fig. 1, but present in each of the following figures of the drawings) is adapted to be connected to the 25 pro~ end 17 of housing 15 after device 10 has been placed CA 02229~33 1998-02-13 W O 97/06758 PCT~US96/13348 in the urethra of a patient and retainer 30 has opened in the bladder of the patient.
Referring now to Fig. 2, there is shown a cross-sectional plane view of the assembled apparatus of this invention comprising bladder control device 10. It can be seen that a nut 33, having a central lumen, is used to mount spring 30 within the lumen of housing 12. It can be seen that the leaves of spring or upper retainer 30 are in their uncompressed or extended position, as they would be when inside the bladder of a patient. It can also be clearly seen how safety device 31 takes the form of a hemispherical formation at the tip of each of the leaves of leaf spring or retainer 30.
Also in Fig. 2 it can be seen that within the lumen for~ed by flow control housing 15 there is mounted a valve assembly for controlling the flow of fluid through the lumen, the assembly comprising a stopper 16, a biasing means or spring 22, a first mounting ring 18 that defines the inner housing ch~her within which stopper moves, and a second spring mounting ring 24. The ring 24 is mounted within housing 15 and receives the pro~;~-l end of the bias means or spring 22. Ring 18 is mounted for rotational movement within housing 15, and has its distal movement inhibited by a ridge 13 within housing 15. Spring 22 extends through mounting ring 18 and has its distal end connected to stopper 16, which CA 02229~33 1998-02-13 WO 97/06758 PCT~US96/13348 stopper 16 is slidably mounted for ~l~v, -nt within the lumen of housing 15.
Also shown in the Fig. 2 depiction of the assembled blA~1r~r control device 10 is a second or lower retainer 35.
~et~;nPr 35 has a first portion adapted to be connected to the proximal end of housing 15, preferably by a threaded connection. Retainer 35 also has a second section which is significantly wider than either of housings 12 or lS, and thus it will be wider than the urethra after placement of device 10 within the urethral. The second portion or wider portion of retainer 35 is adapted to contact the labia.
As is apparent from the study of Fig. 2, when fluid from the bladder achieves a predeter~ined pressure, which can be pressure applied by the muscles of the patient, the normal bias' of spring 22 will be overcome and stopper 16 will slide proximately to open the valving apparatus to allow the flow of fluid from the bladder through device 10 and from the urethra as i nr1 ic~ted by the arrow. It should be noted that nut 33, ring 18, spring 22, ring 24, and retainer 35 all have internal fluid flow paths which align with the axis of the lumens of housings 12 and 15 so that the only major inhibitor of fluid flow from the bl~r~Pr through the urethra is stopper 16 when it is in place. When stopper 16 is slid proxi ~lly by the pres~ure of the bl~er fluid, the stopper 16 is sized such that fluid will flow around it within the lumen of housing 15.
CA 02229~33 1998-02-13 Referring now to Fig. 3, the apparatus of Fig. 2 is shown in exploded view. ~ere it can be seen how nut 33 is placed to hold the blA~er ret~;n;ng means or spring 30 within the lumen of housing 12. It can also be seen how housing 15 has its distal end connected to the pro~;m~l end of housing 12. It can also be seen how stopper 16 is positioned through the lumen of housing 15 to abut a narrowed inner portion of the lumen of housing 15 and how ring 18 is then slid through the pro~; -1 end 17 of the lumen of housing 15 to abut the ridge 13 in the wall of the lumen of housing 15. Spring 22 then has its upper or distal portion placed through the lumen of housing 15, through ring 18 and into connection with stopper 16. Ring 24 is then placed to receive the pro~;m-o~l end of bias means or spring 22 and is pushed through the pr~;mol end 17 of housing 15 and connected within the lumen of housing 15. Finally, after placement of the apparatus of Fig. 3 within the urethra of the patient, the second ret~;ne~ or lower retA;ner 35 is threaded into position at the pro~; m~o. 1 end 17 of housing 15.
As is apparent, when the exploded parts of Fig. 3 are assem~led, they will form the assembled device 10 as shown in Fig. 2.
Re~erring now to Fis. 4 there is sh~w~ a~o~e~ exploded view forming yet another embo~; ~nt of the apparatus of this invention. It will be apparent from Fig. 4 that all the parts of this embo~; m~nt are the same as the parts of Figs. 2 and 3 CA 02229~33 1998-02-13 WO 97/06758 PCT~US96/13348 with the exception of an extender 40 placed between ring 24 and ret~in;ng means 35. Thus when the parts of the spring valving of Figs. 2 and 3 have been properly placed through the pro~i ~1 end 17 of housing 15 and are held in place by ring 24, housing 15 is adapted to receive the distal end of ext~e~ 40, preferably by threading, and retainer 35 is then connected to the pro~i~l end of ext~n~e~ 40 instead of the pro~i--l end of housing 15. Thus the apparatus of Fig. 4 shows an emboAi -nt of the apparatus of this invention whereby the length of device 10 can be selectively changed by utilizing any one of a number of different sizes of extender 40.
Referring now to Fig. 5 there is shown a partial cross-sectional view representative of the urethra and bladder of a patient. In Fig. 5 the bladder control device 10 is shown after placement in the urethra of the patient and after whatever placement devices which were used have been removed and the urethra has undilated to closely hold and form to the outer surface of device 10. It can be seen how retainer 30 in the form of a leaf spring has opened within the bladder and how the safety devices on the tips of the leaves of spring 30 provide a safety factor to prevent puncture of the bladder wall by the tips of the leaves. Finally, it can be seen how the second or lower retainer 35 when connected to the pro~; ~D 1 end of device 10 contacts the labia of the urethra, and how device 10 is thus held within the urethra by retainer 30 and CA 02229~33 1998-02-13 W O 97/06758 PCT~US96/13348 35 acting at opposite ends of the urethra. It should be recognized that the above-described invention derives its ultimate utility when properly placed within the urethra of the patient. Various prior art methods of dilation of the urethra for placement of a device ~uch as device 10 may be known in the prior art. ~owever, it is believed that the most advantageous apparatus for such placement is fully described in co-pending U.S. application Serial No. 08/515,564, filed August 16, 1995, entitled BLADDER CONTROL INSERTION APPARATUS, owned and assigned to the assignee of this invention, and hereby incorporated by reference in this disclosure.
Having thus described the preferred ~mho~ nts of the present invention, those of skill in the art will readily appreciate other useful embo~ nts within the scope of the claims hereto att~che~.
