Abstract: A polymer composition for use in forming a stent is described. The composition includes a monomer of an aliphatic ester of acrylic acid which has a glass transition temperature less than 25° C. and a second monomer that copolymerizes with the first monomer and which has a glass transition temperature greater than 25° C. The components in the composition are mixed in amounts suitable to give a copolymer having a glass transition temperature less than 25° C., or in case of block copolymers, having at least one glass transition temperature less than 25° C. A stent including polymer members formed from the described composition is also disclosed.

Abstract: A stent for insertion into a lumen, having rigid regions and flexible regions along its length, and one or more polymer members coaxially disposed about the outer surface of the stent The polymer members are positioned over the rigid regions of the support stent, while the flexible regions are uncovered and free of polymer members, wherein the polymer members are radially expandable with the support stent.

Abstract: A method of inhibitng cellular proliferation associated with a hyperproliferative condition, such as restenosis, is described. The method includes administering a topoisomerase inhibitor. A stent for local administration of the topoisomerase inhibitor is also described.

Abstract: A stent for use in a lumen defined by a wall of a vessel of a patient having a body. The vessel is comprised of a hollow substantially cylindrical member formed of a biocompatible composition. The composition incorporates at least one medical agent in a weight up to 90% of the total weight of the stent so that at least one medical agent is released from the composition of the stent into the vessel at a controlled rate extending over a period of time after the stent is inserted into the vessel.

Abstract: A radially-expandable stent for insertion into a lumen is described. The stent is composed of a radially-expandable support stent and a polymer tubular member co-axially disposed over the support stent. Tubular end sleeves are disposed around the first and second ends of the polymer-surrounded support stent to secure the tubular member and to provide other improvements.

Abstract: A unit cell for use in a medical device, such as a stent, is disclosed along with a description of a stent formed from a plurality of unit cells and for use in the treatment of restenosis or other vascular narrowing. The unit cell is designed and configured for uniform radial expansion with minimal axial shortening and recoil, and is selectively variable in flexibility and expendability.

Abstract: A stent designed to be carried on the balloon of a balloon catheter to a target site is described. The stent is formed of a series of expandable, strip-like segments, each formed of a memory polymer and adapted for movement between a closed, high-curvature condition and an expanded, low-curvature condition upon exposure to a selected stimulus.

Abstract: An endoprosthetic device for insertion at a vascular site is described. The device is composed of a structural member carrying a polymer member having an embedded therapeutic compound. The polymer member is formed of a shape-memory polymer for expansion upon exposed to a selected stimulus. The structural member is designed for coexpansion with the polymer member when the device is exposed to the stimulus.
