摘要:
Apparatus and methods for stenting are provided comprising a stent attached to a porous biocompatible material that is permeable to endothelial cell ingrowth, but impermeable to release of emboli of predetermined size. Preferred stent designs are provided, as well as preferred manufacturing techniques. Apparatus and methods are also provided for use at a vessel branching. Moreover, embodiments of the present invention may comprise a coating configured for localized delivery of therapeutic agents. Embodiments of the present invention are expected to provide enhanced embolic protection, improved force distribution, and improved recrossability, while reducing a risk of restenosis and thrombus formation.

摘要:
A prosthetic stent with a tubular wall having local inwardly or outwardly formed elevations. Stents having such elevations have a higher mechanical stability if bend according to the curvature of the body vessels to be supported or repaired. Also a method for manufacturing a stent with such elevations is described.
摘要:
A body compatible device including an elongate filament substantially uniform in lateral cross-section over its length and having multiple fibers having high tensile strength embedded in a polymeric material. The polymeric material may be melted onto the fibers, and the filament may have an elongate polymeric case surrounding the filament. The body compatible device may be a stent of a tubular latticework.
摘要:
The stent delivery device has an elongated sheath with a self-expandable stent placed in contracted condition within the distal area of the sheath. An elongated core is arranged in the sheath for relative longitudinal motion between core and sheath, and drive means are arranged between the core and the stent. Scratch protection tubular means comprise a reinforcement ring secured in the sheath and surrounding the distal end portion of the stent when the stent is in contracted condition in the sheath and a tube of thermoformable material heat shrunk over the proximal end portion of the stent and over the core.
