Publication number: 20160346083Abstract: Methods and apparatus for holding and maneuvering a valve during preparation and attachment to patient, providing increased visibility of the prosthetic valve and the sewing ring to prevent suture entanglement. A handle attachment is spaced from the valve for improved visibility of the sewing ring and the outlet end of the valve during attachment. Commissure posts are bent inward at the tips while preventing crashing of the commissure posts into each other causing damage. A release force needed to remove the holder and unthread the holder sutures is reduced. The holder and related methods can provide a kink free holder suture path to reduce suture entanglement and prevent damage to the implanted valve during holder removal by reducing the release force needed to remove the holder sutures by up to 30%.Type: ApplicationFiled: August 12, 2016Publication date: December 1, 2016Inventors: Cathy A.

Patent number: 9283073Abstract: An annuloplasty ring including a sheath, an arcuate stiffening element, and a tensioning member. The stiffening element is disposed within the sheath and defines discrete, first and second ends separated by a lateral spacing. The tensioning member extends between the stiffening element ends. The tensioning member is characterized as being more flexible than the stiffening element and is configured to provide a taut state in which the tensioning member is substantially non-extensible and impedes expansion of the lateral spacing. With this configuration, the stiffening element serves to remodel the valve annulus to a desired shape, while the tensioning member exhibits sufficient flexibility to allow for natural movement of the valve annulus while limiting (in the taut state) the extent of annular dilatation (e.g., overt lateral separation of the first and second ends of the stiffening member) due to in vivo forces.Type: GrantFiled: May 31, 2007Date of Patent: March 15, 2016Assignee: Medtronic, Inc.Inventors: Timothy R. Ryan, Cathleen A. Bergin, Jerald Redmond
