摘要： A catheter system for mechanical dilatation of coronary arterial stenoses includes a balloon dilatation catheter, a guide wire and a guide catheter. The balloon dilatation catheter has, for the perfusion of vessel fluid during dilatation, side openings arranged both distal and proximal of the balloon and connected to one another via a lumen extending within the balloon. The internal lumen configuration of the balloon dilatation catheter permits the catheter system to be utilized as either a "monorail"-type or an "over-the-wire" system.

摘要： The dilatation catheter has a shaft which consists of two separately produced shaft portions. Both portions have a first lumen for a guide wire and a second lumen for a pressure liquid. The two portions overlap at a connection point and are preferably welded to one another at this point. The proximal portion consists of two coaxial tube portions and the distal portion consists of an extruded two-lumen tube piece. The proximal portion is stiffer than the distal portion, which permits an optimal adaptation to a non-straight course of a blood vessel. The dilatation catheter according to the invention is particularly suitable for the treatment of arterial occlusions, which are situated in or downstream of a vessel curve.

摘要： A body implantable stent is formed of a plurality of strands arranged in two sets of coaxial helices, wound in opposite directions to form multiple crossings. At selected crossings, the adjacent strands are welded to one another, while at the remaining crossings the strands are free for limited movement relative to one another. The welds are formed in patterns that preferably enhance radial strength and rigidity, while having a minimal impact on axial bending flexibility. Preferred weld patterns in this regard include rings or circumferential rows, and helices, particularly with a steeper pitch than that of the strands. Stent fabrication preferably involves resistance welding at the crossings, and use of a tool to reuniformly compress the stent around and against the distal end region of a balloon catheter used later to deliver the stent to a treatment site.

摘要： The endoprosthesis is inserted under tension in a recess of a flexible inner catheter and secured by means of a tube-shaped outer catheter. To release the endoprosthesis into a vessel, the outer catheter is pushed back over the recess. The recess is formed by a connector piece that connects a tip to a piece of tubing of the inner catheter. The inner catheter can be designed with a smaller outer diameter in the region of the recess than was previously the case with at least the same flexibility and resistance to buckling.

摘要： 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.
摘要翻译：用于打开心血管系统中收缩区域的导管包括可膨胀扩张区，包括围绕支撑管设置的三个扩张元件。膨胀元件是管状构造，并且每个在一端与在支撑管中的通道连通，通向压力 - 抽吸泵。通过在折叠状态下将扩张区引入受影响部位并在其周边扩张，可以扩大或打开心血管系统中的约束区域。在膨胀元件膨胀时，流体通道形成在这些元件之间，体液（例如血液）可以以很小的阻力通过。从而维持了对受影响部位下游的器官和组织的体液的供给。不需要中断扩张治疗以确保这种供应，从而可以显着减少医疗程序的总体持续时间。导管例如可用于扩张由动脉硬化损伤和瓣膜成形术程序收缩的血管，也可用于治疗食道中的收缩。
