A catheter shaft includes a first tube made of an extrudable copolymer that has reactive groups, and a second tube made of a polymeric material, which is welded to the first tube. A distal balloon is welded to the first tube.

Catheter shaft comprising welded tubes

An implant having a preferably hollow cylindrical basic structure. A nonwoven fabric is disposed in and/or on the basic structure, the nonwoven fabric preferably comprising biocompatible thermoplastic polyurethane and/or a polymer selected from the group consisting of polylactic acid, polycaprolactone, and a copolymer thereof, and/or a polymer including polyphosphazene. At least in at least one section of the implant, preferably at the proximal and/or distal ends of the implant, fastening means are provided or the nonwoven fabric is treated such that, at least in the expanded state of the implant, the protrusion of nonwoven fabric sections from the implant is significantly reduced. Furthermore, a method for producing such an implant is provided.

Implant and method for producing the same

An implant having a preferably hollow cylindrical basic structure. A nonwoven fabric is disposed in and/or on the basic structure, the nonwoven fabric preferably comprising biocompatible thermoplastic polyurethane and/or a polymer selected from the group consisting of polylactic acid; polycaprolactone, and a copolymer thereof, and/or a polymer including polyphosphazene. At least in at least one section of the implant, preferably at the proximal and/or distal ends of the implant, fastening means are provided or the nonwoven fabric is treated such that, at least in the expanded state of the implant, the protrusion of nonwoven fabric sections from the implant is significantly reduced. Furthermore, a method for producing such an implant is provided.

The invention relates to a drug-coated balloon catheter and to a method for producing the same. The balloon of the catheter includes (i) a main membrane, and (ii) an asymmetrical polymer membrane which is applied to an outside of the main membrane and into which at least one pharmaceutical active ingredient is introduced.

Drug-coated balloon catheter and method for the production thereof

One embodiment of the invention relates to a catheter shaft comprising (i) a first tube made of an extrudable copolymer that has reactive groups, and (ii) a second tube made of a polymeric material, which can be welded to the first tube, wherein the polymeric material of the second tube can be welded to the first tube at a temperature &#x2266;200&#xb0; C.

Mixtures made of PE and COC, in particular for use in medical materials, so as to reduce the frictional forces. The mixtures comprising or consisting of PE and COC, wherein &#x2267;70% by weight, preferably &#x2267;90% by weight, and still more preferably 100% by weight, relative to the total mass of PE, of PE in the mixture is HDPE.
