Publication number: 20090082843Abstract: The invention is directed to a self-expanding stent for implantation into a body lumen, such as an artery. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common longitudinal stent axis and interconnected by a plurality of interconnecting members placed on the stent in a collinear arrangement such as to create at least one continuous spine which extends along the length of the stent. The invention is also directed to a stent delivery system for implantation of a stent in a vessel which includes an outer tubular member having a restraining sheath and an inner tubular member having a distal end which has a compressed stent mounted thereto. The proximal end of the inner tubular member is connected to a housing assembly which prevents the inner tubular member from moving when the outer tubular member is retracted to deploy the stent.Type: ApplicationFiled: September 25, 2008Publication date: March 26, 2009Applicant: ADVANCED CARDIOVASCULAR SYSTEMS, INC.Inventors: Daniel L.

Patent number: 6814749Abstract: Stent designs for use in peripheral vessels, such as the carotid arteries, are disclosed. The stents consist of a plurality of radially expandable cylindrical elements generally aligned on a common longitudinal stent axis and interconnected by one or more interconnecting members placed so that the stent is flexible in a longitudinal direction. The cylindrical elements are generally serpentine wave pattern transverse to the longitudinal axis between alternating valley portion and peak portions, the valley portion including alternating double-curved portions and U-shaped portions.

Patent number: 6547766Abstract: An intraluminal catheter customizable to accept various diameter guide wires is disclosed. The catheter has a large bore lumen for receiving a large diameter guide wire, and alternatively, for receiving an adaptor tube therein. The adaptor tube includes a small guide wire lumen for accepting smaller guide wires of various diameters. With the adaptor tube telescopically disposed within the large bore catheter, the distal end of the adaptor tube optionally projects beyond the distal end of the large bore catheter. To minimize any onset of snow plowing effects at the distal end of the catheter, the outside diameter of the adaptor tube is made to closely conform to the inside diameter of the large bore catheter. An end cap is tightly fitted to the proximal end of the large bore catheter. The end cap secures the large bore catheter to the proximal end of the adaptor tube by the latter's interference fit with a concentric stub tube on the end cap.Type: GrantFiled: May 11, 2000Date of Patent: April 15, 2003Assignee: Advanced Cardiovascular Systems, Inc.Inventor: Matthew J.
