BACKGROUND This invention relates to drainage devices intended to be implanted in a living body, and more particularly to devices of this type which are valve controlled and intended to be retained in the bladder and urethral canal for the purpose of controlling drainage therefrom.

Herctofore, various kinds of drainage devices, commonly known as catheters, draining probes, dilators, surgical instruments, etc., have been proposed and/or produced to cope with problems involving obstruction, operative procedures, examination of tissue, removal of fluids and the like. These prior devices were as a rule restricted in their use to the specific purpose originally in mind, and none could be satisfactorily utilized, for instance, as a fairly long term implant in the urethra or urinary tract to permit drainage of urine at will from the bladder. Such a long term drainage control device, moreover, is greatly needed and would find widespread use and acceptance.

It is known that patients who have neurogenic bladders due to congenital spinal cord defects, spinal cord or brain injury, or other neurologic diseases present a major economic problem because of persistent incontinence.

Also, patients who have incontinence of urination caused either by muscle weakness or postoperative surgical damage to the urinary sphincter, are candidates for a satisfactory, long term drainage device which could provide controlled periodic emptying of the bladder. Many such patients are not suitable for surgical correction of incontinence.

In addition, patients who have lower urinary tract obstruction, whose physical condition does not permit operative relief of this obstruction, can greatly benefit by having their bladder drained periodically by use ofa long term drainage control implant, until such time as operative intervention is permitted.

Efforts to meet and solve this longstanding problem have in general been directed toward the provision of an externally carried reservoir or bag, in which the urine collected, to be periodically removed at the user's convenience. This type of device was, at the very best, a poor solution to the problem, for many quite obvious reasons not considered necessary to enumerate in connection with the present invention.

SUMMARY The above disadvantages and drawbacks of prior devices are obviated by the present invention, and one object of the invention is to provide a novel and improved self-operated, internally contained valved drainage control device which can be implanted in the urinary tract and readily retained therein for extended periods of time so as to effect urinary continence, thereby to successfully cope with the above-mentioned urinary problems arising from various causes. Another object is to provide a readily operated valved drainage implant suitable for extended periods of use, which can be utilized in various, different locations in the body for the indicated purpose, being not restricted to the urinary tract.

These objects are accomplished by the provision of a novel valve means adapted to be disposed in the body, actuator means for the valve which includes at least one flexible wire, which either extends through or along the inside of an elongate novel pervious means comprising a slim flexible catheter tube having multiple perforations in its walls to permit a flushing of the walls of the body passage, particularly when the valve is actuated to the open position. The control cable or wire extends through the perforated tube to the external oriflee, and the perforations of the tube enable an exchange and passage of liquids to occur, facilitating drainage and the natural functioning of the surrounding tissues whereby the likelihood of irritation, infection and incompatibility is greatly minimized, to the extent that the implant can be well tolerated without giving rise to undesired side effects.

The novel valve means comprises an electromagnet and a permanent magnet core disposed in a sealed chamber at the inner end of the catheter tube. One wall of the chamber comprises a corrugated diaphragm which spans the interior of the tube and which constitutes the valve element that is actuated by the magnetic core. Adjoining the diaphragm is an annular valve seat which is engaged by a valve facing of the diaphragm, for the purpose ofcontrolling fluid flow.

Other objects of the invention are to provide an improved long term drainage implant as above set forth, which is especially simple in construction, economical to fabricate and produce, small and compact, readily adaptable to both male and female patients, safe to use, and effective and reliable in operation.

Yet other features and advantages will hereinafter appear.

In the drawings:

FIG. 1 is a side elevational view of a valved drainage control device as provided by the invention.

FIG. 2 is a fragmentary sagittal median section through a female pelvis showing the present improved valved drainage control device in its implanted operative position extending through the urethra.

FIG. 3 is an axial sectional view, enlarged, of the valve drainage control device of the invention, shown with the valve in its closed condition.

FIG. 4 is a fragmentary axial sectional view of the valve por tion of the drainage control device, with the valve in the open position.

Referring first to FIG. 1, the drainage control device of the invention as shown therein comprises a slim, flexible catheter tube I0 ofinert plastic material, said tube having a closed and pointed forward or inner end portion 12 provided at a distance from its tip with a plurality of inlet openings 14. Adjacent the inlet openings 14 is a collapsible and inflatable enlargement or bulb 16 adapted to be expanded or inflated to a position such as is shown in FIG. 3.

The catheter device of FIG. 1 is intended to be inserted into and retained in the urethral canal 18 of a living person, as illustrated in FIG. 2, with the inflated retainer bulb l6 occupying the bladder 20, the other end of the catheter being located at the exterior of the body and having a discharge orifice fitting 22. It will be understood that during the insertion of the catheter the bulb 16 is in the deflated condition as shown in FIG. 1, and that after insertion the bulb is inflated by a suitable fluid such as water, in the manner of the well-known Foley catheter.

Referring to FIG. 3, for the purposes of inflation of the bulb, the tube 10 is provided with an internal channel 24 which communicates with an inflation fitting 26 provided with a plug or check valve 28 at its end. The wall of the catheter tube 10 has an opening 30 through which fluid introduced into the inflation fitting 10 can enter the bulb l6 and expand it to the position shown in FIGS. 2 and 3 for purposes of retaining the device in the desired position.

In accordance with the present invention, the catheter tube It] is provided with multiple perforations or apertures 32 to facilitate a flushing of the walls of the body passage or urethra when drainage of the bladder 20 is occurring through the tube [0. The provision of such perforations tends to reduce the likelihood of irritation of the walls of the urethral canal, since there is minimized the possibility of accumulation of any discharge with accompanying discomfort and possible infection, Instead, the walls of the urethral canal have communica tion with the interior of the catheter tube It) at a large number of locations. enabling a drainage to occur which tends to improve the condition of the urethral wall.

Also in accordance with the invention, a novel and improved valv e arrangement is provided at the innermost end of the catheter tube l0. Considering FIGS. 3 and 4 there is shown flexible circular diaphragm 34 which spans the interior of the tube adjacent the inner, closed end portion 12 thereof, said diaphragm forming with said closed end portion a sealed chamber 36. Located in the chamber 36 is a DC electromagnet coil 38 and also a magnetic core 40 constituted of permanent magnet material. The core 40 is biased away from the end wall of the tube 10 by a helical compression spring 42, and is able to move vertically in the coil 38 as viewed in FIGS. 3 and 4. The magnet core 40 is secured to the inner face of the central portion of the diaphragm 34, as by a suitable adhesive. The outer face 44 of the central portion of the diaphragm 34 constitutes the valve element, being cooperable with an annular valve seat 46 which is disposed in the tube 10 to span the interior thereof adjacent the diaphragm 34 Above the valve seat 46 are the inlet openings 14 of the tube,

Considering FIG. 3, when the electromagnet coil 38 is not energized, the biasing spring 42 will maintain the magnet core 40 and valve facing 44 of the diaphragm in a lowered position wherein the opening of the valve seat 46 is closed, preventing drainage of liquid from the bladder 20. When the electromagnet coil 38 is energized with proper polarity, it will pull upward the core 40 and the diaphragm 34, uncovering the central opening of the valve seat 46 whereby drainage from the bladder can occur through the openings 14, valve seat 46, and then through the catheter tube 10.

Energization of the coil 38 can be effected by means of lead wires 48 carried in a flat tape 50 which is adhered to the interi' or ofthe catheter tube [0.

In place of the wire-containing tape 44, the lead wires from the coil 38 may be brought through the inflation channel for the bulb l6. Thus, as seen in FIGS. 3 and 4, a second set of lead wires 52 is shown as extending through the channel 24, such wires being brought out at the inflation fitting 26 and being connected with a battery 54 and with a manually operable on-off switch 56 For such arrangement, the channel 24 will extend closely adjacent the annular valve seat 46. The channel 24 is formed by an interior beadlike wall portion 58 which is either molded in the tube 10 or attached to the tube after the latter has been initially formed. The entrance and exit arrangements of the lead wires 52 are done in such a manner that a fluidtight seal is had, thereby to not impair the inflation of the bulb [6, as will now be understood, By having the lead wires 52 brought through the inflation channel 24, the flat tape 50 with the wires 48 may be dispensed with; or such tape may be retained and constitute an alternative conductor for effecting energization of the coil 38 if the conductor 52 should fail or break for some unforseen reason.

The sealed valve arrangement which is shown in FIG. 4 has considerable advantage, since the locating of the movable core 40 in the sealed chamber 36 prevents contamination of the core and the spring 42, and the formation of deposits or caked material which might impair the functioning of the valve.

The diaphragm 34 is formed of an inert. flexible rubberlike material such as silicone rubber, neoprene rubber or the like, The valve seat 46 can be formed of a tough resilient plastic such as polytetrafluorethylene, known commercially as Teflon. The bulb l6 and catheter tube H] are formed ofinert resilient plastic or rubberlilte material. The sealed tip portion 12 of the catheter tube 10 may be constituted as a separate part to facilitate insertion of the electromagnetic valve in the inner end of the tube. After placement of the valve mechanism, the tip portion [2 may be sealed to the tube 10 by a suitable heat-sealing or cementing procedure The flexible nature of the diaphragm 34 tends to prevent caking and deposits from forming on it, to impair the functioning thereof. Also, the slippery surface characteristics of the Teflon valve seat 46 will similarly prevent the adhering of deposits whereby the valve mechanism is not likely to malfunction during an ex tended period of use.

Referring to FIGS. 3 and 4 it will be noted that the openings 14 and the drainage openings 32 in the tube 10 are provided with well-rounded edges, thereby to prevent any possibility of irritation to the walls of the urethral canal at the time that the drainage device is being inserted, retained or removed, and this is an important feature of the invention,

It will now be understood from the foregoing that I have provided a novel and improved drainage catheter which may remain for extended periods of time in the urethral canal for the purpose of controlling and preventing incontinence, said device being so constituted as to provide for improved drainage from and around the walls of the urethral canal to minimize the likelihood of irritation thereof. Further, the drainage device has a novel sealed electromagnetic valve mechanism by which remote control is had in a reliable and convenient manner, such valve mechanism being especially constituted by location in a sealed chamber and utilizing a flexible diaphragm valving element, to minimize the likelihood of malfunctioning or jamming of the valve.

Variations and modifications are possible without departing from the spirit of the invention.
