[0111] Angioplasty and Stenting Procedures

[0112] The devices, systems and methods described herein are used to treat coronary artery disease by positioning one or more stents within any coronary artery 4 and releasing the one or more stents figure 1 heart shown. Stenting can be performed in conjunction with angioplasty or can be "direct stenting," which simply delivers the stent to maintain the body vessel without balloon angioplasty. However, pre- and / or post-inflation of the balloon at the lesion site to be treated may also be employed. The balloon can be delivered to the lesion site before or after delivery of the delivery system, in which case the delivery system can be used as a guide for the balloon catheter. Alternatively, the balloon itself may be located on the delivery system.

[0113] Advantageously according to U.S. Patent Application Publication No. 2004 / 0193179, published September 30, 2007, and filed December 24, 2003, "Balloon Catheter Lumen-Based Stent D...

Abstract

Medical devices and methods for delivery or implantation of prostheses within hollow body organs and vessels or other luminal anatomy are disclosed. The subject technologies can be used in the treatment of atherosclerosis in stenting procedures or be used in variety of other procedures. The systems can employ a self expanding stent restrained by one or more members released by an electrolytically erodable latch.

Description

Background of the invention [0001] Implants such as stents and occlusive coils may be used in patients for a variety of reasons. One of the most common "stenting procedures" is used to treat arteriosclerosis, a disease that causes body cavities such as coronary arteries to narrow and narrow. In angioplasty, a balloon is inflated to open the blood vessel at the site of the stenosis (ie, the site of the injury). To help keep the passage open, a stent is placed in the body cavity. Restenosis can be avoided solely by the structural support of the stent, or by relying on one or more drugs carried by the stent. [0002] Various stent designs have been developed and used clinically, but superelastic self-expanding stents and balloon-expandable stent systems currently dominate. Described herein are unique devices, systems and methods for self-expanding stent delivery and other applications. Contents of the invention [0003] The devices, systems, and methods described herein are...
