  • Patent number: 8974521
    Abstract: An implant having a preferably hollow cylindrical main structure comprising a large number of continuous openings and a coating which releases at least one pharmaceutically active substance. To attain a better distribution of the pharmaceutically active substance, at least 20% of the cross-sectional area, preferably at least 50% of the cross-sectional area, of at least a portion of the openings in a predetermined section of the main structure is covered with the coating which releases at least one pharmaceutically active substance. Furthermore, a system composed of a catheter and such an implant, a simple method for manufacturing such an implant or such a system is provided.

  • Publication number: 20140030310
    Abstract: The present invention relates to a method for manufacturing an implant, in particular an intraluminal endoprosthesis, having a body containing metallic material, preferably iron. The following manufacturing method is provided for promotion of the anti-inflammatory effect of the implant: (i) providing the body of the implant; (ii) producing an at least partially closed pore structure in a portion of the structure of the implant body close to the surface; and (iii) incorporating NOx into the cavities of the pore structure. Also described is an implant manufactured in this manner.

  • Publication number: 20120109276
    Abstract: The present invention relates to a catheter comprising a balloon (10, 30) and at least one pharmaceutically active substance. To enable more accurate dosing of the pharmaceutically active substance, the pharmaceutically active substance is disposed in a reservoir (15, 35) inside the balloon (10, 30) or on the balloon (10, 30), wherein a wall (14, 32, 34) that closes the reservoir toward the outside comprises at least one predetermined breaking point (16). Furthermore, a system for applying an intraluminal endoprosthesis, preferably a stent, in a body cavity, and simple and cost-effective methods for manufacturing the catheter and the system are described.
