An implant (&#x2033;), in particular an intraluminal endoprosthesis, with an open-worked, hollow cylindrical and/or hollow conical main structure (), wherein the main structure () can adopt a compressed state or an expanded state. To simplify final assembly by the doctor, a first tubular shaft (') is additionally provided, on the outer face of which the main structure () is arranged in the compressed state, at least in portion, wherein the first shaft (&#x2032;) has a first connection portion (), with which the first shaft (&#x2032;) can be connected to the inner shaft () of a catheter (&#x2033;). A corresponding system formed of an implant of this type and of a catheter (&#x2033;) and a method for producing such a system.

Implant, system formed of an implant and a catheter, and method for producing such a system

A balloon catheter comprises an outer shaft having a distal end, an inner shaft situated therein to form an annular fluid line and projecting beyond the distal end of the outer shaft, and a balloon which is dilatable under the influence of a fluid introduced through the fluid line under pressure. At its proximal end the balloon is attached in a fluid-tight manner to the distal end region of the outer shaft at a first attachment zone, and at its distal end is attached in a fluid-tight manner to the distal end region of the inner shaft at a second attachment zone. Between the attachment zones, in the undilated state the balloon is placed in longitudinal folds along its length. The balloon, at least at its distal end, has an untapered design with a thin wall thickness (d) which is essentially unchanged over the length of the balloon, and the longitudinal folds extend into the attachment zone at that location.

Balloon catheter and method for manufacturing same

A balloon catheter, including an outer shaft with a distal end and a fluid line, an inner part located distal anterior to its distal end, as well as a balloon that can be inflated under the influence of a fluid that has been pressurized by the fluid line, that is fastened fluid-tight onto the distal end section of the outer shaft with a first fastening zone at its proximal end, and fluid-tight onto inner part with a second fastening zone at its distal end, whereby the balloon, on at least one of its two ends is designed without cone and with essentially unvarying thin wall thickness, the balloon is provided on at least one of its two ends with respectively one twist anterior to its fastening zone, and a second balloon is placed above the first balloon and is also provided with a twist on at least one of its two ends anterior to the fastening zone, that is directed in the opposite direction of the twist of the first balloon end that is positioned underneath.
