Appl. No.:

12/975092

Inventors:

Alain F. Carpentier - Paris, FR
Alison S. Curtis - Irvine CA, US

Assignee:

Edwards Lifesciences Corporation - Irvine CA

International Classification:

A61F 2/24

US Classification:

623 219, 623 236

Abstract:

A prosthetic remodeling tricuspid annuloplasty ring having two free ends can be configured to more accurately mimic native valve anatomy (e.g., shape) and movement during the cardiac cycle. A tricuspid ring can be provided with a substantially elliptical shape in the X-Y plane, and a bimodal saddle shape in the Z direction. The tricuspid ring can be configured to contract and expand during each cardiac cycle such that the area of the orifice and/or the diameter of the ring decrease with each contraction. Further, the elevation or non-planarity of the bimodal saddle shape can increase with each contraction. Movement of the tricuspid ring can vary in each different segment of the tricuspid ring. Tricuspid annuloplasty rings can be provided in a set, with changing ratios of diameter, changing out-of-plane static amplitudes, and changing amounts of dynamic movement in each different size of tricuspid ring.

International Classification:

A61F 2/24

US Classification:

623 236

Abstract:

A prosthetic tricuspid remodeling annuloplasty ring having two free ends can be configured to be stiff in the XY plane and relatively flexible along the Z axis. A tricuspid ring can be provided with a substantially elliptical shape in the XY plane, and a saddle shape in the Z direction. Disclosed tricuspid rings can include an inner core, an elastomeric interface, and an outer fabric covering. In some embodiments, the inner core can include a plurality of stacked layers of different materials. In some embodiments, the inner core can be formed of a single material and sized specifically to create a tricuspid ring that has a greater stiffness in the XY plane than along the Z axis.

US Classification:

623 237

Abstract:

Devices and related methods of use are provided for improving heart function. In one embodiment of the present disclosure, a device includes a ring-like structure configured to be secured to a heart valve; at least one elongate member extending from the ring-like structure, wherein an end of the elongate member is configured to be secured to heart geometry other than a heart valve; and an adjustment mechanism for simultaneously altering a dimension of the ring-like structure and a length of the elongate member.

US Classification:

623 111, 623 211

Abstract:

Disclosed herein are representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve to a deficient valve. In one embodiment, for instance, a support structure and an expandable prosthetic valve are advanced through the aortic arch of a patient using a delivery system. The support structure is delivered to a position on or adjacent to the surface of the outflow side of the aortic valve (the support structure defining a support-structure interior). The expandable prosthetic valve is delivered into the aortic valve and into the support-structure interior. The expandable prosthetic heart valve is expanded while the expandable prosthetic heart valve is in the support-structure interior and while the support structure is at the position on or adjacent to the surface of the outflow side of the aortic valve, thereby causing one or more native leaflets of the aortic valve to be frictionally secured between the support structure and the expanded prosthetic heart valve.

US Classification:

623 236

Abstract:

A prosthetic remodeling annuloplasty ring for use in tricuspid or mitral valve repairs to provide support after annuloplasty surgery. The annuloplasty ring includes a relatively rigid core extending around an axis that is discontinuous to define two free ends. A suture-permeable interface surrounding the core includes floppy regions adjacent both free ends of the core. Sutures are used to attach the annuloplasty ring to the annulus, including at least one suture through each of the floppy regions to secure the free ends of the ring and minimize the risk of ring dehiscence, or pull through of the sutures through the annulus tissue. The floppy regions may project from each free end into the gap toward each other, be radially enlarged such as paddle-like extensions, or may comprise outwardly lateral extensions at the free ends of the core.
