  • Patent number: 8197538
    Abstract: An annuloplasty prosthesis including a sheath, an arcuate stiffening element, and an imaging element. The arcuate stiffening element is disposed within the sheath and defines discrete, first and second ends separated by a lateral spacing. The imaging element is disposed within the sheath along the lateral spacing. With this configuration, following implant to the valve annulus, the imaging element provides a mechanism for non-invasively evaluating a shape of the valve annulus, for example, via radiographic, echogenic and/or other image enhancing visualization techniques. In some embodiments, the annuloplasty prosthesis provides a radiographic, echogenic and/or other image enhanced image of a near entirety of the valve annulus.

  • Patent number: 8105376
    Abstract: An annuloplasty band comprising a sheath, and a generally arcuate stiffening element disposed within the sheath. The stiffening element extends from a first end to a second end, and preferably includes eyelets at its first and second ends adapted to receive sutures to secure the annuloplasty band to a valve annulus. The annuloplasty band preferably has a low profile (e.g., a thickness less than 3 mm). In embodiments intended for mitral valve repair, the eyelets are particularly adapted to receive sutures to secure the annuloplasty band to the antero-lateral trigone and postero-medial trigone. A holder and sizer device useful with the annuloplasty band are also provided.

  • Publication number: 20120022641
    Abstract: 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%.

  • Patent number: 8057538
    Abstract: The present invention is an improved apparatus for holding and maneuvering a valve during preparation and attachment to patient. The present invention is particularly useful for increased visibility of the prosthetic valve and the sewing ring to prevent suture entanglement. The present invention is used most effectively with mitral valves having commissure posts on the outflow side of the valve structure but may be used with other valve configurations. The present invention spaces the handle attachment from the valve for improved visibility of the sewing ring and the outlet end of the valve during attachment. The present invention is adapted to safely bend the commissure posts inward at the tips while preventing crashing the commissure posts into each other causing damage.

  • Patent number: 8048152
    Abstract: A simplified and more easily employed tool for holding an implantable annuloplasty prosthesis during passage of sutures through the prosthesis and for conveniently and efficiently releasing the prosthesis from the tool. Separation of the implantable prosthesis and the tool may be conveniently accomplished without requiring the use of a sharp instrument. Attachment between the prosthesis and its surgical carrying tool can be accomplished in a suture-less fashion. The tool includes a suture management device in some embodiments for selectively receiving and maintaining sutures otherwise securing the prosthesis to tissue.

  • Publication number: 20110264207
    Abstract: A heart valve that can be expanded following its implantation in a patient, such as to accommodate the growth of a patient and the corresponding growth of the area where the valve is implanted, and to minimize paravalvular leakage. In one aspect, the invention may maximize the orifice size of the surgical valve. The invention includes expandable implantable conduits and expandable bioprosthetic stented valves. In one aspect of the invention, the valve may be adapted to accommodate growth of a patient to address limitation on bioprosthetic valve lifespans.

  • Patent number: 8029564
    Abstract: A prosthetic heart valve system including a prosthetic heart valve and a deflection device. The deflection device includes a line and a connector assembly including a tensioning component. The line interconnects and passes through free ends of stent posts associated with the heart valve, and is further connected to the tensioning component. The tensioning component is transitionable to a tensioning state in which the line is tensioned to inwardly deflect the stent posts. In this regard, the tensioning component is self-locking relative to the line in the tensioning state, and an entirety of the line extending distal the tensioning device does not extend beyond a stent portion of the heart valve opposite the stent posts. In a preferred embodiment, a holder body is further included, coupled to the heart valve apart from the deflection device.
