    摘要: This is an implantable medical device assembly for use in surgical procedures. It is most preferably an implantable structure having stenting properties but only partially coated with or partially associated with a material causing a localized angiogenic response. One variation of is an artificial occlusion kit having the inventive implantable stenting structure situatable and vaso-occlusive devices. The implantable stenting structure is typically situated so to prevent migration of artificial occlusion devices or implants from an occlusion site, such as an aneurysm, and into an adjacent body space, such as a blood vessel.

    摘要: This invention is to a minimally invasive surgical device. In particular, the invention relates to an infusion catheter which may be used in cardiovascular and endovascular procedures to deliver diagnostic, therapeutic, or vasoocclusive agents to a target site accessible through the vasculature. The device is a flow-directed infusion catheter having a variety of sections of different flexibilities with tapered junctions between those sections. The inventive catheter is directed to that target site by a flow of blood to the site.

    摘要: The present invention provides resistance to degradation from environmental stress cracking (ESC) and metal ion induced oxidation (MIO) for implantable, flexible pacing lead insulators having a body of polyether polyurethane elastomer material. A thin layer of a second polyurethane elastomer is applied as an overcoat to the lead insulator body. The second polyurethane is more resistant to ESC and MIO than the elastomer comprising the body of the insulator. Because ESC and MIO are surface phenomina, only a thin layer of the second material is required and the mechanical properties of the base material will determine the overall mechanical properties of the lead insulator.
