摘要: A stent (scaffold) or other luminal prosthesis comprising circumferential structural elements which provide high strength after deployment and allows for scaffold to uncage, and/or allow for scaffold or luminal expansion thereafter. The circumferential scaffold is typically formed from non-degradable material and will be modified to expand and/or uncage after deployment.

摘要: An endoprosthesis includes a plurality of serpentine rings having supporting features which increase hoop strength, inhibit recoil, and provide an increased surface area. The supporting features may be formed between adjacent axial struts of the serpentine rings or may be positioned between axial lengths joining the serpentine rings together.

摘要: The present invention provides improved devices and methods for minimizing and/or inhibiting restenosis and hyperplasia after intravascular intervention. In particular, the present invention provides luminal prostheses which allow for programmed and controlled mycophenolic acid delivery with increased efficacy to selected locations within a patient's vasculature to inhibit restenosis. An intraluminal delivery prosthesis may comprise an expansible structure and means on or within the structure for releasing mycophenolic acid at a rate selected to inhibit smooth muscle cell proliferation.

摘要: An intravascular balloon catheter includes a tubular catheter body having a balloon structure removably mounted over the catheter body. The catheter body has a guidewire lumen, and the catheter body may be left in place within a patient's vasculature while the balloon structure is withdrawn and optionally a second balloon structure introduced over the catheter body. The catheter and methods of the present invention are particularly suitable for performing angioplasty and subsequent procedures, such as stent placement, which are best performed using successive interventional balloon structures.
