Patent number: 7118592Abstract: A polymeric material such as polyurethane, PET, or ePTFE is used to cover an intravascular stent. The cover material has an overlapping portion which is slidable upon itself so that when the stent is expanded, the cover material does not contribute to stent foreshortening, if any. The cover material can be provided with holes to permit endothelialization and can be drug loaded to facilitate repair of a damaged vessel.Type: GrantFiled: September 12, 2000Date of Patent: October 10, 2006Assignee: Advanced Cardiovascular Systems, Inc.Inventors: Kenny L.

Patent number: 7108714Abstract: An expandable intraluminal endoprosthesis including a tubular member (1) a first diameter which permits intraluminal delivery of the member into a lumen of a body passageway, particularly a blood vessel. The tubular member (1) is capable of acquiring a second, expanded and deformed diameter upon the application from the interior of the tubular member of a radially outwardly extending force, which second diameter is variable and dependent on the amount of the force applied to the tubular member. Such a tubular member may be expanded and deformed to expand the lumen of the body passageway. The wall of the tubular member includes a substantially continuous structure (2) of mutually staggered undulations. This structure has been separated from a tube wall and exhibits at least one pattern which advances substantially helically along a longitudinal axis of the tubular member. Connection elements within the structure connect adjacent undulations to each other.Type: GrantFiled: February 23, 2000Date of Patent: September 19, 2006Assignee: Orbus Medical Technologies, Inc.Inventor: Gary J.

Patent number: 7060023Abstract: This is a surgical device and a method of using it. In particular, the device is one for reinforcing the pericardial sac surrounding the heart to assist in the treatment of congestive heart failure. The device, generically, is an enclosure having an interior and an exterior. The interior surface is made in such a way that it tends not to or does not form adhesions with or accept ingrowth with the myocardial tissue of the epicardium. The exterior surface of the device, in contrast, is adapted to adhere to or to ingrow with or otherwise attach sufficiently to the pericardium so that it reinforces that membrane or structure. The nature of the device is that it tends not to allow the pericardium to expand further with time. The device, after complete deployment, should envelope some measure of pericardial fluid in its interior separating it from the epicardial surface. This device helps to prevent further declination of the heart during congestive heart failure.Type: GrantFiled: September 25, 2001Date of Patent: June 13, 2006Assignee: The Foundry Inc.Inventors: Ronald G. French, Sunmi K. Chew, Hanson S. Gifford, III, Bernard H. Andreas

Patent number: 7056280Abstract: The symptoms of congenital heart failure are addressed in this surgical procedure for mounting a patch in the ventricle of the heart to reduce ventricular volume. Placement of the patch is facilitated by palpating a beating heart to identify akinetic, although normal appearing, tissue. The patch has an oval configuration facilitating return of the heart to a normal apical shape which enhances muscle fiber efficiency and a normal writhing pumping action. The patch includes a semi-rigid ring, and a circumferential rim to address bleeding. Patch placement is further enhanced by creating a Fontan neck and use of pledged sutures. Intraoperative vascularization and valve replacement is easily accommodated. Increased injection fraction, reduced muscle stress, improved myocardial protection, and ease of accurate patch placement are all achieved with this procedure.Type: GrantFiled: August 7, 2002Date of Patent: June 6, 2006Assignee: CorRestore, Inc.Inventors: Gerald D. Buckberg, Constantine L. Athanasuleas

Patent number: 7033387Abstract: A device to provide body fluid flow control in the form of a valve to be located within a duct or passageway. The device is controlled through pressure above a preselected threshold. Bulk resilience about a passageway in a valve body provides the mechanism for controlled flow. One-way valve operation may be provided through a flap or through a pressure differential on the valve body depending upon the direction of flow. A frame structure positioned within a resilient seal includes longitudinally elongate elements which may be of spring material, malleable material or heat recoverable material so as to accomplish an initial insertion state and an expanded anchoring state. A valve support transitions between the resilient seal portion and the valve body to insure that the states do not change the threshold opening pressure. Insertion devices may be employed to position and actuate a change of state of the frame in the body duct or passageway.Type: GrantFiled: April 18, 2003Date of Patent: April 25, 2006Assignee: Emphasys Medical, Inc.Inventors: Gholam-Reza Zadno-Azizi, John S.
