International Classification:

A61F 2/24

US Classification:

623 237

Abstract:

A prosthetic tricuspid remodeling annuloplasty ring for use in tricuspid valve repairs to provide annular support after reconstructive valve surgery. The ring maintains an optimal annular dimension to prevent excessive dilatation of the natural valve annulus while adapting to the dynamic motion of the tricuspid annulus during the cardiac cycle. An exemplary ring features a waveform contour and may be constructed of a titanium core having a varying cross-section for selective flexibility for good Z-axis or out-of plane movement. The “waveform” contour and selective flexibility of the different segments of this ring are designed to adapt to the complex motion of the annulus. This reduces the stress on the anatomical structures and therefore minimizes the risk of arrhythmia and ring dehiscence.

International Classification:

A61F 2/24

Abstract:

Valve repair devices and systems configured to detect proper valve leaflet insertion. The device/system can have a pair of paddles and a clasp attached to each of the paddles. The clasps may have a fixed arm attached to the paddle, a movable arm connected to the fixed arm that is movable between an open position and a closed position, and an indicator arm connected to at least one of the fixed arm and the movable arm. The indicator arm can move between a first position when not engaged with a leaflet and a second, engaged position when engaged with the leaflet. Movement of the indicator arm from the first position to the second, engaged position indicates capture of a leaflet of the native valve by the pair of paddles.

International Classification:

A61F 2/24

Abstract:

A minimally-invasive annuloplasty ring for implant at a mitral annulus. The annuloplasty ring has an inner core member with a C-shaped plan view that generally defines an oval with a major axis and a minor axis, and is symmetric about the minor axis. A posterior portion of the core member bisected by the minor axis has a thicker radial dimension than a pair of free end regions terminating on an anterior side of the core member. The radial thickness smoothly transitions between the posterior portion and the end regions. The inner core member may be covered with a fabric, and is a superelastic metal so that it can be straightened out and delivered through an access tube. The curvatures and thicknesses around the core member are selected so that the strain experienced when straightened does not exceed 7-8%.

International Classification:

A61F 2/24

Abstract:

A prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be reshaped into an expanded form in order to receive and/or support an expandable prosthetic heart valve therein. A dual-wireform support frame including an upper and a lower wireform permits expansion of the valve by one or two valve sizes, for example, with a 2-mm gap between each valve size. The lower wireform has a relatively shallow undulation so that it may stretch apart by a small amount and then prevent further expansion of the valve.

International Classification:

A61F 2/24

US Classification:

623 217

Abstract:

Disclosed herein is a prosthetic heart valve, and associated methods therefore, configured to replace a native heart valve, and having a support frame configured to be reshaped into an expanded form in order to receive and/or support an expandable prosthetic heart valve therein. The prosthetic heart valve is configured to have an expansion-resistant configuration when initially implanted to replace a native valve (or other prosthetic heart valve), but to assume a generally expanded form when subjected to an outward force such as that provided by a dilation balloon or other mechanical expander.
