Patent number: 6267782Abstract: A variety of new ways can be used for associating antimicrobial elemental metal with a medical article. The associated antimicrobial metal reduces the risk of infection associated with the medical use of the medical article. New medical articles are produced by some of these new approaches. Some of the methods involve ways of adjusting the dissociation rate of associated elemental metal such that desired degrees of antimicrobial activity can be achieved over selected periods of time.Type: GrantFiled: August 31, 1998Date of Patent: July 31, 2001Assignee: St. Jude Medical, Inc.Inventors: Matthew F.

Patent number: 6258122Abstract: This invention relates to heart valve annuloplasty prostheses that are fashioned of bioresorbable materials. The prostheses are eventually resorbed by the patient, during which time regenerated tissue replaces the prosthesis. This leaves the patient with a biological and functional annular structure, resulting in improved heart valve function.Type: GrantFiled: February 5, 1997Date of Patent: July 10, 2001Assignee: St. Jude Medical, Inc.Inventors: Katherine S.

Patent number: 6254636Abstract: A semilunar stentless valve is constructed entirely of biocompatible material, and has a plurality of leaflets that are joined to form an annulus and coapt to form a one-way valve. The leaflets open fully to minimize obstruction. A narrow rim strip overlies commissures where the leaflets join and around a base of the valve. The valve is of a conical design, flexible, easy to fit and preserves the integrity of the coronary sinuses. The valves can be implanted with a single suture row, reducing implant time significantly.Type: GrantFiled: June 26, 1998Date of Patent: July 3, 2001Assignee: St. Jude Medical, Inc.Inventor: Mario Osvaldo Vrandecic Peredo

Patent number: 5735842Abstract: A manipulable low profile heart valve holder that can be pivotally attached to a handle that permits the heart valve holder and a retained heart valve prosthesis to be manipulated remotely during implantation. The heart valve holder is pivotable from a position wherein the plane of the orifice of a retained heart valve is parallel to the axis of the handle, to a second position wherein the plane of the retained heart valve is substantially 90.degree. to the axis of the handle. This pivoting arrangement particularly aids in manipulation of the heart valve prosthesis during implantation using trocars for access to the body cavity. Manipulation is accomplished by having controllable elements on the handle and retained on the exterior of the patient. Manipulation of the heart valve holder also may be done through separate instruments operating through separate trocars.Type: GrantFiled: September 11, 1995Date of Patent: April 7, 1998Assignee: St. Jude Medical, Inc.Inventors: Kurt D. Krueger, Michael J. Girard, Guy P. Vanney
