Abstract: A method for repairing a native valve of a patient during a non-open-heart procedure includes attaching two or more attachment members to the native valve. The method also includes applying a force to the two or more attachment members such that the two or more attachment members cause a cinching effect on at least a portion of the native valve. The method further includes securing the two or more attachment members with one or more anchor members such that the two or more attachment members maintain the cinching effect.

Abstract: A heart valve sizer and sizer cover are provided for determining the size of a heart valve annulus. The valve sizer can include a handle, a shaft extending distally from the handle, a sizing element coupled to the distal end of the shaft, the sizing element being movable between a first retracted position and a second expanded position, and a sizer cover. The sizer cover can be formed from a continuous sheet of material configured to surround at least a portion of the sizing element of the heart valve sizer so as to guard against entanglement of the sizing element with structures of a human heart.

IPC: A61F2/24
Abstract: A prosthetic heart valve configured to replace a native heart valve and for post-implant expansion and having a valve-type indicator thereon visible from outside the body post-implant. The indicator communicates information about the valve, such as the size or orifice diameter of the valve, and/or that the valve has the capacity for post-implant expansion. The indicator can be an alphanumeric symbol or other symbol or combination of symbols that represent information about the characteristics of the valve such as the valve size. The capacity for post-implant expansion facilitates a valve-in-valve procedure, where the valve-type indicator conveys information to the surgeon about whether the implanted valve is suitable for the procedure and informs the choice of the secondary valve.

Abstract: An articulating implant holder system for heart valve repair or replacement has an implant configured to be secured to a heart valve annulus, an implant holder secured to the implant, an articulating handle assembly comprising a handle, a swivel pivotably secured to the handle at a first location and a connector pivotably secured to the swivel at a second location, an actuating cable secured between the handle and the connector to cause the swivel to move from a first position to a second position, and a latch removably secured to the implant holder. A plurality of sizer heads are configured to correspond to different sizes of heart valve annuluses and each of the plurality of sizer heads has a latching feature. A latching feature of the swivel is configured to removably snap on to the latching feature of each of the plurality of sizer heads and is configured to permanently snap on to the latch.

IPC: A61F2/24
Abstract: A sewing ring for prosthetic heart valves that is connected and configured to pivot outward. A biocompatible fabric covering surrounds at least a portion of the sewing ring, and the ring may be exclusively connected to a stent with the fabric. The sewing ring may be generally planar and of uniform thickness, or may be of varying thickness. The fabric may be used to encompass both the stent and the sewing ring, and may be a single piece. A seam may be provided in the fabric as a discrete pivoting line. The sewing ring may be convertible between bi-stable positions. The ring may extend outward in a frusto-conical shape so as to enable inversion between a position facing the inflow end of the valve and a position facing the outflow end of the valve. The sewing ring may have a compliant insert having a celled construction defined by outer walls and inner ribs. A method of implantation, and a method of assembly of the heart valve is also provided.

Abstract: Valve holders and introducers for delivering a prosthetic heart valve to an implant site are in various embodiments configured to facilitate insertion of prosthetic valves through small incisions or access sites on a patient's body. The valve holders can also be configured to reduce or eliminate the occurrence of suture looping or other damage to the prosthetic valve during implantation. A valve holder according to embodiments of the invention includes features that reduce or eliminate mistakes during implantation of the prosthetic valves, such as a removable activator dial and a removable handle that prevent implantation of the valve prior to proper deployment or adjustment of the holder. An introducer is provided which can facilitate passing of a prosthetic valve between adjacent ribs of a patient. Valve holders and introducers according to the various embodiments can be used in minimally invasive procedures, such as thoracotomy procedures.
