Abstract: The invention relates to a balloon catheter featuring—at least on portions of the outward-turned surface of the dilatable area—hair-like extensions, with the average diameter D, the average length L, and the average center-to-center distance P of the hair-like extensions to each other being selected such that a drug on the balloon surface covered with hair-like extensions can essentially be secured by means of capillary forces.

Abstract: A stent made of a material having a low strength and having a main body circumscribing a cylindrical shape and radially expandable from a contracted starting position into a dilated support position, comprising a) a plurality of support segments disposed around the circumference and arrayed on one another in the axial direction each segment being formed by a strut meandering in its coarse structure in its contracted starting position and having alternately opposing meandering curves expandable into the support position made of flexible material; b) a plurality of axial connectors connecting between zenith points of at least a part of the meandering curves in the axial-parallel direction of the support segments; (c) a plurality of x-ray marker projections, and d) at least one stabilizer for stabilizing the strut coarse structure in its contracted starting position against radial expansion and being automatically detachable upon radial expansion.

Abstract: A stent comprising an essentially tubular open supporting structure (4) of interconnected trusses (9), whereby the supporting structure (4) can be widened radially with deformation of the trusses (9) for application of the stent, and predetermined breaking points (14) in the supporting structure (4) for fragmentation of the stent after application, and the ends (10, 11) of the trusses (9) that are adjacent to the respective predetermined breaking point (14) having a joint design and which are provided in the area of the predetermined breaking point (14), such that the ends (10, 11) of the trusses (9) are held together with articulation under an applied pressure with the predetermined breaking point (14) broken.

Abstract: A catheter (10) having an internal tube (13) and an external tube (14) which at least sectionally encloses the internal tube (13). The external tube (14) is connected to a balloon (16) having an endoprosthesis section (18) which positions an intraluminal endoprosthesis (20). The catheter (10) has stiffening means (31, 33, 34, 35) located in the area of at least one end of the endoprosthesis section (18) in its longitudinal direction on the internal tube (13). Also disclosed is a system comprising an intraluminal endoprosthesis (20) and a catheter (10) used for introducing an intraluminal endoprosthesis (20), preferably a stent, into a body cavity.

Abstract: The invention relates to an implantation device for stents, which device has hair-like extensions on at least one part of the outwardly-facing surface of that section of the device, which section is provided to attach or crimp on the stent to be implanted, wherein the mean diameter D, the mean length L, and the averaged center-to-center distance P of the hair-like extensions relative to each other are selected such that a stent is affixable on the surface covered with hair-like extensions essentially by means of van der Waals forces.

Abstract: The invention relates to a catheter having a single-layer inner tube, the single-layer inner tube with an inner surface forming a lumen and with an outer surface forming an outer surface of catheter duct, it being possible to arrange one or more guide wires in the lumen of the inner tube, characterized in that the single-layer inner tube is made of a material including: a) 96 to 99.9% by weight of a polymer, a copolymer, and/or a mixture of several polymers and/or copolymers; b) 0 to 1% by weight talc; c) 0 to 1% by weight calcium carbonate; d) 0 to 1% silicon dioxide; e) 0 to 1% by weight waxes; wherein the sum of the weight percentages of constituents b) to e) is at least 0.1% by weight, and no more than 4% by weight, and wherein all weight percentage information relates to the total weight of the single-layer inner tube.

Abstract: A stent fixation system 3 for fixation of a stent, comprising two retaining areas 10 which are connected by a connecting area 12 to form a fixation tubing. The retaining areas 10 provide a retaining structure which is designed to hold at least one stent strut 2 of the stent in the undilated state, such that the stent struts 2 are no longer in one of the retaining areas 10, at least in the dilated state of the stent.

Abstract: A multilayered catheter tube element (10), preferably for situating a guide wire, comprising a first layer (11) forming the external layer and a second layer (12) at least partially forming the internal layer. The first layer (11) contains at least one plastic or multiple plastics from the group consisting of PEBA, polyamide, and elastomer-modified polyamide and the second layer (12) contains ethylene tetrafluoroethylene. A cost-effective method for producing a multilayered catheter tube element of this type is also disclosed.
