Abstract
P.C. 7029 CATHETER FOR OPENING CONSTRICTED REGIONS
IN THE CARDIOVASCULAR SYSTEM
Abstract A catheter for opening constricted regions in the cardiovascular system includes an expandable dilatation zone comprising three dilatation elements arranged around a support tube. The dilatation elements are of tubular configuration, and each communicates at one end with a passage in the support tube leading to a pressure-suction pump. Constricted regions in the cardiovascular system may be enlarged or opened by introducing the dilatation zone into the affected site in a folded condition and expanding it peripherally therein. Upon expansion of the dilatation elements flow passages are formed between these elements, through which body fluid (for example blood) can pass with little resistance. The supply of body fluid to organs and tissues downstream of the affected site is thereby maintained. Interruption of the dilatation treatment is not required to insure this supply, thus permitting a substantial reduction in the overall duration of the medical procedure. The catheter may be employed, for example, to dilate blood vessels constricted by arteriosclerotic lesions and in valvuloplasty procedures, and may also be employed for treating constrictions in the esophagus,

P.C. 7029 CATHETER FOR OPENING CONST.RICTED REGIONS
IN TEIE CARDIOVASCULAR SYSTEM
__ _ The present invention relates to a catheter for opening constricted regions in the cardiovascular system of a patient.
Catheters of this kind have been in use for some time, for example to treat arterioscleEotic vascular co strictions. Such catheters have an expandable balloon at the distal end, to be brought into the region of constriction in a folded condition. By means of a passage accessible from the outside of the catheter, the balloon is filled with ~luid so that it expands peripherally, and the tissue bringing about the constriction is pressed outward into the vessel wall.
The expanded balloon blocks the vessel completely, so that the treatment must be periodically interrupt~d after brief intervals, for example to preverlt distal ischemia. Owing to the necessary interruptions, the over-all duration of treatment is correspondingl~
lengthened .
It is an object of the present invention to provide a catheter of the aforementioned kind whereby, even cluring a prolonged dilatation of the constrictic)n, the continuous supply of blood and oxygell to the downstream organs and tissues is maintained, which catheter is economical in manufacture and yet dependable in operation.
This and other objects of the invention are achieved with a novel catheter including an expandable -2~ S
dila~atiorl zone comprislng a plurality of dilatation eleme~ts arr~.nged around an elongated support tube, with the walls of the expanded di.latation elements, ta~en together, exhibiting a generally circular cross--section.
In the expanded condition, the dilatation elements and the wall of the treated vessel form several pass2ges through which body fluid or a gas can freely pass. Thus, in the case of three dilatation elements ~-~ arranged side-by-side around the support tube, three of sv.ch passageC. are ormed peripherallv hetween the wall of the treated vessel and the walls of adjacent dilatation e].ements, each of these passages extending ~hrough the dilatation ~one in the lengthwise direction ~5 of the catheter. Passage of the body fluid through the di.latation zone is assured even if some of the passages are blocked.
Since, instead of one large dilatation element, a plurality oE correspondingly smaller dilatation elem.nts are employedl a higher dilatation pressure is obtainable. This is because smaller dilatation elements can be subjected to a higher internal pressure. Thus, for example, a tubular dilatation elernent about 18 mrn in diameter may be subjected to an internal pressure of only about 200,000 Pa, wher~as a simiJ.ar d.ilatation element about 8 mm ln cli.ameter will withstand an internal pressure of about 800,000 Pa.
Compared to the known catheters of this kind, the overall duration of treatment can be shortened subst~.ntially, because dilatation of the constriction need not be interrupted periodically to insure an adequate supply of body fluid to tissues and or~ans.
~urther advantageous features and refinements of the invention are described elsewhere in the present application.

Bet.ween the ends 3d and 3e of the cli]atation eiements 3a-c, the support tube 2 may be sincJle-lumened, or of the same configuration as outside -this zone.
-4~ 85 The dilatation elemellts 3a c in expanded condition exhibit crvss-sec~ionally a yenerally circular wall, but may alternatively be elliptical instead, depending on the specific application. The inflation of the dilatation elements 3a-c may be effected in known manner with a liquid medium or gas. For this purpose, the interiors of the dilatation elements 3a-c are preferably interconnected, so that they may be respectively expanded simultaneously. When using the support tube of FIG. 2a, the passa~es 9a-c are joined on the pump side for this purpose. Conceivabl~, however, the dilatation e]ements 3a-c may instead be separately supplied and independently inflated.
The support tube 2 has a passage 8 or 20 leading to the outside at the tip 29, through which a guide wire 32 may be thrust, or contrast media as well as medication delivered. On the support tube 2, marking elements 4 of a suitable metal may be provided for locating the dilatation zone by X-rays.
~0 The support tube 2 is connected to a fitting 31 pro~ided with a connection 6 for the pressure-suction plm~p, and a gauge ~nd injection connection 7.
The use of a support tube 2a as in FIG~ ~a has been ~ouncl especially suitable. It has a cylindrical wall 11 subdivided internally by partit:ions 10a-c into a triangular inner passage a an~ three outer passages 9a-c. The outer passages 9a-c lead to the pressu,e-suction pump and to the dilatation elements 3a-c, whlle the inner passage 8 opens to the outside at the tip 29. However, the configuration o~ the support tube may instead be as shown in FIG. 2b. This double-lumened tube 2b has an outer annular passage 31 communicating with the dilatation elements 3a-c. A
coaxial inner wall 22 forms an inner passage 20 through -5- ~5~
~hich a ~t~-d~ wire 3~ ~ay be thrust. In this elnbodi.ment the sp~ces in passage 31 between the .respec.iv~ ends 3e of the dilatation elements are fil,led with pieces of a suitabl--~ sealing material such as an epoxy polymer Ino~- shown in the igures). The tubes 2a and 2b are flexible and may be made of a suitable pl.astic, for example by e~trusion.
The cat:heter according to the invention is brought in~o the region of the place to be clilated with the aid 1l~ of the guide wire 3~ in a mannex known.per se, with the dilat..ltion elements 3a-c folded as schematically represented in FIG. 3a. The dilatation elements 3a-c are then expanded to the requ:ired size by increased pressl1re. In this condition, the walls la-c o the d.i]ata~ion elements 3a-c, taken together, are generall~
circular in cro.s;-section and press externally against the wall 33 of the constrict.ion (FIG. 3b). Upon in''lation of the di].atation elements 3a-c, central passages 25 and peripheral passages 26 are formed, extending through the dilatation zone 1 in the lengthwise direction of the catheter, so that body fluid can pass through zone 1 with only slight resistance.
Since t,he flow oE the bocly fluicl is not interruptea~ ~. period of thexa.peutic intervent.ion of ade~,~uate length, during which the dilatation of the constl~i.ct.i-)n need not be interrupted, is available.
Compared to the use of known catheters, the overall durat:ion of t.he treatment can thereby be reducecl substanti.ally.
The catlleter according to the invention may be u.sed to en:l.arc3e constrictions in ,all sorts of vessels carryinc3 body fluids. Examples of other fields of application are the treatment of. constrictions in the esophagus or in the bile duct. Simult:aneously with the -6- ~3~ 5 dilati~n of the constriction, chemical substances may be introdu~e(l into thè body through the central passage, or, for example, the blood pcessure may be measured.
The catheter of the invention is particlllarly suitable for use in valvuloplasty procedures, in which the leaElets of stenotic heart valve~, in particular the aor-tic and mitral valves, are forced apart to re-open the valve and restore it to full Eunction, without havirg to perform open heart surgery. The advhntages of the use o the catheter of the present invention (as compared to a dilatation catheter having onlv a single expandable dilatation element) are the increased surface pressure that can be applied to force 1~ open the valve and, when three dilatation elements are ernployed as shown in the igu~es herein/ the capability to concenlrate that. pressure at 120 intervals ~as viewed in FIG. 3b), which is ideally suited for openiny the calcified seams of stenotic tri-leaflet valves.
In a preferred valvuloplasty procedure for opening a stenotic aortic valve, for example, a catheter of the invention (with the dilatation elements folded and non-expanded) carrying an appropriate guide wire 32 may be inserted through a suitable guiding catheter into the Eemoral arteryO The catheter and guide wire are advanced together to the end of the gl~iding catheter, after which the guicle wire is advanc~d by itsclf to th~
stcnotic valve and through the remaining opening thereo. The catheter of the invention is then advanced along the guide wire until the dilatation zone is positionecl in the valve opening, and the dilatation eleltlents are then expanded to open the valve. After deElating the dilatation elements the catheter of the invention, guide wire and guiding catheter are withdrawn from the patient 1 5 body.
