Patent number: 8764817Abstract: Disclosed are methods for securing the intersection formed by two or more crossed strands. The intersection defines at least two sections. The practice of the disclosed methods includes bending a securing material, such as a suture or other suitably biocompatible material, through at least two of the sections formed by the intersection, and joining them to secure the intersection. Also disclosed are devices formed by using securing material to secure the intersection of crossed strands of a medical device, such as a woven stent. The secured intersection or intersections of the resultant device enhance the structural integrity of the device, and may serve to eliminate the possible unwinding or release of unsecured, or free, strand ends. Radiopaque materials, in addition to polymers, may be used as securing material.Type: GrantFiled: March 5, 2002Date of Patent: July 1, 2014Assignee: IDEV Technologies, Inc.Inventor: Jeffery J.

Publication number: 20140048097Abstract: Methods of treating a device such as an endoprostheses or a batch thereof include first soaking the device in nitric acid for greater than 1 hour; after first soaking the device, first sonicating the device in deionized water for between about 5 minutes and about 20 minutes; and after first sonicating the device, repeating, at least once, soaking the device in nitric acid for greater than 1 hour, and, after soaking the device in the nitric acid, sonicating the device in deionized water between about 5 minutes and about 20 minutes. Methods may further include soaking in a mild acid for between about 30 minutes and about 45 minutes. The methods may form a protective oxide having a thickness between about 30 ? and about 100 ?.Type: ApplicationFiled: August 15, 2013Publication date: February 20, 2014Applicant: IDev Technologies, Inc.Inventors: Kenneth M.

Patent number: 8414635Abstract: Self-expandable, woven intravascular devices for use as stents (both straight and tapered), filters (both temporary and permanent) and occluders for insertion and implantation into a variety of anatomical structures. The devices may be formed from shape memory metals such as nitinol. The devices may also be formed from biodegradable materials. Delivery systems for the devices include two hollow tubes that operate coaxially. A device is secured to the tubes prior to the implantation and delivery of the device by securing one end of the device to the outside of the inner tube and by securing the other end of the device to the outside of the outer tube. The stents may be partially or completely covered by graft materials, but may also be bare. The devices may be formed from a single wire. The devices may be formed by either hand or machine weaving.Type: GrantFiled: May 22, 2008Date of Patent: April 9, 2013Assignee: IDev Technologies, Inc.Inventors: Hideki Hyodoh, Andras Konya, Kenneth C. Wright

Publication number: 20110295354Abstract: A pusher assembly for a stent delivery device includes a distal end of an elongate member and a stent-engaging member having proximal and distal ends. The proximal end of the stent-engaging member is mechanically coupled to the distal end of the inner member by a connector, or the proximal end of the stent-engaging member is at least partially inside the distal end of the elongate inner member. The stent-engaging member includes a portion that radially outwardly extends towards the distal end of the stent-engaging member, or the stent-engaging member includes a portion that radially outwardly extends towards the distal end of the stent-engaging member. The stent-engaging member is configured to move a stent when distally advanced and configured to not move a stent when proximally retracted. A stent delivery device includes an elongate outer member, an elongate inner member coaxially positioned within the outer member, and the pusher assembly.Type: ApplicationFiled: May 27, 2011Publication date: December 1, 2011Applicant: IDEV TECHNOLOGIES, INC.Inventors: Kenneth M. Bueche, Michael P. Igoe, Derek Blakeney, Ronald G. Earles
