Patent number: 10548723Abstract: A stented valve having at least one leaflet made of pericardium or other material having a relatively thin profile at the annulus. The leaflets are attached via chords to a stent frame, where the chords are positioned to mimic the native valve anatomy and functionality. In particular, the valves of one exemplary embodiment of the invention are sized to replace a mitral valve and therefore the chords are arranged to prevent prolapse of the leaflets into the atrium. The stented valve has a relatively short height at its annulus due to the positioning of the chords. In addition, the stented valve is capable of being crimped to a small enough size that it can be delivered to the implantation site via transcatheter delivery systems and methods.Type: GrantFiled: October 25, 2017Date of Patent: February 4, 2020Assignee: Medtronic, Inc.Inventors: Alexander J. Hill, Cynthia Clague, Carol E. Eberhardt, Ana Menk, Mark J. Capps, Billie Millwee, Janice Lynn Shay, Debra Taitague, Joseph C. Morrow, Jerald Redmond

Patent number: 7740656Abstract: A heart valve sewing prosthesis including an intrinsically conductive polymer. The invention includes annuloplasty rings and bands, and sewing rings or cuffs for prosthetic heart valves. Some annuloplasty rings and sewing rings include fabric that is coated with an intrinsically conductive polymer. The coating can be formed over individual filaments or fibers, or on the fabric surface as a surface layer. One intrinsically conductive polymer is polypyrrole. The intrinsically conductive polymer can be doped to facilitate the intrinsic conductivity. Some devices have a polypyrrole surface layer doped with dialkyl-napthalene sulfonate. The intrinsically conductive polymer can be deposited on a fabric using in-situ polymerization of monomeric or oligomeric species, together with a dopant. Animal studies using implanted annuloplasty rings having an intrinsically conductive polymer coating have demonstrated a substantial reduction in pannus formation and inflammatory response.Type: GrantFiled: November 17, 2003Date of Patent: June 22, 2010Assignee: Medtronic, Inc.Inventors: Eugene A. Mensah, Mark J. Capps, Chris M. Coppin, Jeffrey M. Gross

Patent number: 5546820Abstract: A fixture for testing a circumferentially compliant bioprosthetic valve. The fixture comprises a silicone rubber simulated aorta which approximates the geometry of a healthy human aorta and a cradle for the aorta. The compliance characteristics of the aorta can be selected by varying the proportions of ingredients in the silicone rubber, so that simulated aortas of different compliance but identical geometries can be provided. The compliant valve is disposed inside the aorta and held in place by suturing or the like. In one embodiment, the aorta and valve are supported by means of a cylindrical cradle, with the inflow and outflow ends of the aorta being folded over cylindrical rims on the respective inflow and outflow ends of the cradle. End caps are then fitted in place over the folded-over ends of the aorta, the end caps having holes therein to allow flow through the aorta and valve.Type: GrantFiled: November 14, 1994Date of Patent: August 20, 1996Assignee: Medtronic, Inc.Inventors: Carol E. Eberhardt, Mark J. Capps, Luis Salazar
