Abstract: An apparatus and process is disclosed for the electrolytic removal of metal from a device, such as a medical device. More particularly, the apparatus of the invention includes a mandrel having slots or openings therein to expose portions of a metallic device, such as a stent, to an electrolytic solution to remove metal from the exposed portion.

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 links. The rings are defined by undulations of relatively large and relatively small amplitudes wherein bar arms extend between peaks and valleys and wherein selected bar arms are non-linear. The links connecting the cylindrical rings are non-linear.

Abstract: An expandable stent for implanting in a body lumen, such as a coronary artery, peripheral artery, or other body lumen is provided. An intravascular stent is formed by cylindrical rings connected by links. The rings have peaks and valleys from which extend straight and nonlinear bar arms, forming a figure-eight. An elemental unit is defined with straight and nonlinear bar arms, and elemental units on adjacent rings are mirror images of one another. The links have one end connected at a peak of one ring and the other end connected to a central portion of a nonlinear bar arm. Alternating rows of the links consist of nonlinear links.
