摘要： A biocompatible solid-solution alloy which may be formed into any number of implantable medical devices is described. The solid-solution alloy comprises a combination of elements in specific ratios that make it magnetic resonance imaging compatible while retaining the characteristics required for implantable medical devices. The biocompatible solid-solution alloy is a cobalt-chromium alloy having substantially reduced iron and/or Silicon content.
In one embodiment, the alloy comprises nickel in the range from about 20 weight percent to about 24 weight percent, chromium in the range from about 21 weight percent to about 23 weight percent, tungsten in the range from about 13 weight percent to about 15 weight percent, manganese in the range from about 0 weight percent to about 1.25 weight percent, carbonl in the range from about 0.05 weight percent to about 0.15 weight percent, lanthanum in the range from about 0.02 weight percent to about 0.12 weight percent, boron in the range from about 0 weight percent to about 0.015 weight percent, iron in an amount not to exceed 0.12 weight percent, Silicon in an amount not to exceed 0.12 weight percent and the remainder cobalt.

摘要： A system for placing a stent into the side branch of an arterial bifurcation. The system includes:

(i) An inflatable balloon (15') located at a distal portion of a stent delivery system (16'), the stent delivery system having an outer shaft (11) with a longitudinal length, the outer shaft having a distal end that is fixedly attached to the proximal end of the balloon.
(ii) A pre-deployed side branch stent (14) mounted coaxially onto the balloon for placement into the side branch of an arterial bifurcation, the stent having a proximal end and a distal end.
(iii) A guide wire (6); and

摘要： A preferred embodiment of a stent provides a folded strut section that provides both structural rigidity and reduction in foreshortening of the stent mechanism. A flexible section provides flexibility for delivery of the stent mechanism. In a second embodiment, flexible section columns are angled with respect to each other, and to the longitudinal axis of the stent. These relatively flexible sections are oppositely phased in order to negate any torsion along their length. In yet another embodiment, the flexible connector can take on an undulating shape (like an "N"), but such that the longitudinal axis of the connector is not parallel with the longitudinal axis of the stent. Finally, a new method is disclosed for making stents. The method consists of performing a standard photochemical machining process of cutting, cleaning and coating the tube with a photoresist. However, unlike former methods, the photoresist image is developed on the surface of the cylindrical metallic tube, which results in a controlled variable etching rate at selected sites on the cylindrical metallic tube during the etching process. Further embodiments provide living hinge connectors and connections along the length of the radial strut member.
