Abstract: The catheter comprises a catheter tube formed of two superposed tubular layers of materials which differ from one another. A tubular mediator layer is arranged between the layers to provide an adhesive anchorage for the layers.

Abstract: A prosthetic stent with a tubular wall having local inwardly or outwardly formed elevations. Stents having such elevations have a higher mechanical stability if bent according to the curvature of the body vessels to be supported or repaired. Also a method for manufacturing a stent with such elevations is described.

Abstract: The stent having a flexible self-expandable braided tubular wall having a proximal segment having an outer diameter, and a distal segment having an outer diameter smaller than the outer diameter of the proximal segment. An intermediate segment is formed between the proximal and distal segments, which forms a truncated cone of which the base is forming the proximal end of the intermediate segment and of which the top is forming the distal end of the intermediate segment. A covering layer is arranged within the tubular wall.

Abstract: The medical appliance has an elongated tubular shaft with a lumen extending therethrough and slots in the distal area for pressure medium entry into the lumen. A stiffening means in the form of an independent wire extends through the lumen with its proximal area extending proximally of the shaft. The proximal area of shaft is affixed to a luer-lock comprising a housing with an inner cavity and a distal end forming a muff fixedly and tightly sealed on the proximal end of the shaft.

Abstract: In a catheter system for rapid exchange via a guidewire with a flexible, elongated inner catheter, which has a proximal end and a distal end as well as a guidewire lumen, which extends from an insertion port on the distal end to a lateral through port distally from the proximal end, and a flexible, tubular outer catheter, in which the inner catheter is disposed axially displaceably, and which has a lateral exit port for the guidewire, retaining means are provided on the inner catheter and the outer catheter, which retaining means prevent twisting of the outer catheter relative to the inner catheter. Thus, the through port and the exit port remain aligned with each other and the catheter system can be displaced simply along the guidewire. In addition, the outer catheter can be readily displaced relative to the inner catheter.

Abstract: A catheter device for the treatment of a vessel carrying body fluid, comprising an inner first occlusion catheter, having a first tubular shaft with a proximal end and a distal end, a distal occlusion balloon disposed at the distal end of the first tubular shaft and an inflation lumen extending through the first tubular shaft between a proximal entry at the proximal end and a distal exit inside the distal occlusion balloon, and an outer treatment catheter, having a second tubular shaft with a central lumen extending therethrough for coaxial reception of the first occlusion catheter, and being longitudinally displaceable with respect to the first occlusion catheter, further comprises a seal for the proximal entry of the inflation lumen, having an outside dimension small enough to fit within the central lumen for advancing, resp. withdrawing, a treatment catheter proximally onto, resp.

Abstract: The dental device comprises an elongated inflatable balloon for placement around a matrix band in part surrounding relationship with a decayed tooth. Upon inflation, the balloon evenly applies the matrix band against the tooth.

Abstract: A guidewire threader to facilitate insertion of the proximal end of a guidewire into the distal end of a catheter including two clamping pieces each of which has the shape of a lever having two arms and are hinged to each other for pivoting about a common axis between a closed clamp position and an open release position. A spring maintains clamping surfaces, each of which is provided on one arm of each clamping piece, positively in contact with each other in the clamp position. The clamping surfaces in their condition in contact with each other define a passage oriented roughly parallel to the common pivot axis open at both ends, the passage containing a section having an interior dimension corresponding to the outer diameter of the catheter and which is flared funnel-shaped at both of its ends. In the release position, the clamping surfaces open the passage in the lateral direction for removal of the guidewire.

Abstract: A catheter with a first component, a second component, and a glue line disposed between the components which is filled with an adhesive layer joining the components. The adhesive layer is formed in two plies, whereby a first adhesive ply is bonded to the first component and a second adhesive ply is bonded to the first adhesive ply and to the second component. Thus, even catheter components which could not be bonded to each other with the use of a single-ply adhesive layer or could only be bonded with inadequate stability can be firmly bonded to each other. Moreover, one of the adhesive plies may be applied in the unassembled state of the components.

Abstract: The guidewire comprises an elongated flexible shaft which is tubular. A coil assembly comprises a first coil having a proximal portion with a peripheral size providing an unstressed fit within the distal portion of shaft. Tight recesses formed between consecutive turns of the coil by a solder filler hold adhesive between the coil and the tubular shaft.

Abstract: The guide wire serves in particular for the percutaneous introduction of a balloon dilation catheter into a blood vessel and has a flexible coil which surrounds a likewise flexible shaft and is produced from at least two coil springs, which are rotated together at a connection location over a plurality of turns and are soldered to one another. For the purpose of connection, at the end to be connected, the two coil springs are each slid onto a centering mold, rotated together and soldered. The centering mold is then removed. The connection location is tubular and internally hollow, so that the flexible shaft can be inserted subsequently.
