Abstract: The apparatus and method use an optical feedback system to align a brush assembly with a stent strut. Once alignment is achieved, a coating is dispensed onto the stent strut via the brush assembly and the brush assembly is moved along the stent strut to coat the stent strut.

Abstract: The present invention is directed to a flexible expandable stent for implantation in a body lumen, such as a coronary artery. The stent generally includes a series of metallic cylindrical rings longitudinally aligned on a common axis of the stent and interconnected by a series of links which be polymeric or metallic. Varying configurations and patterns of the links and rings provides longitudinal and flexural flexibility to the stent while maintaining sufficient column strength to space the cylindrical rings along the longitudinal axis and providing a low crimp profile, enhanced stent security and radial stiffness.

Abstract: The invention is directed to an expandable stent for implanting in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. The invention provides for an intravascular stent having a plurality of cylindrical rings connected by undulating links. A plurality of inverted cylindrical end rings can be coupled at least in part to a plurality of adjacent cylindrical rings in the form of mirror images such that a symmetrical configuration is present on at least one of a proximal end and a distal end of the stent. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. The inverted end ring configuration of the stent aims at reducing the stent-to-shoulder distance as well as delivering therapeutic drug to the peri-stent area while maintaining a pristine stent deployment.

Abstract: A delivery system for a medical device. The delivery system comprises an inner member, a retractable sheath disposed over the inner member and being slideable over the inner member, and a retraction member coupled to the retractable sheath and disposed at least in portion within the retractable sheath, the retraction member being slideable over the inner member. An axial movement of the retraction member retracts or actuates the retractable member.

Abstract: An expandable stent for implanting in a body lumen, such as a coronary artery, peripheral artery, or other body lumen includes cylindrical rings connected by undulating links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. The distal and proximal end ring have peaks that extend longitudinally when the stent is radially expanded. The end ring extensions reduce the likelihood of the development of peri-stent restenosis.
