Mitral or tricuspid repair systems with multi-directional anchors
Prosthetic ring valve assemblies are disclosed. A prosthetic valve ring assembly includes an outer tube and a plurality of anchors. The outer tube includes a plurality of windows. The plurality of anchors are positioned inside the outer tube and about a perimeter of the outer tube. The plurality of anchors are configured to be emitted from the plurality of windows in order to anchor the prosthetic valve ring assembly to annulus tissue of a patient.
Implantable heart valve devices, mitral valve repair devices and associated systems and methods
Systems, devices and methods for repairing a native heart valve. In one embodiment, a repair device for repairing a native mitral valve having an anterior leaflet and a posterior leaflet between a left atrium and a left ventricle comprises a support having a contracted configuration and an extended configuration, and an appendage, such as a flap or apron extending from the support. In the contracted configuration, the support is sized to be inserted under the posterior leaflet between a wall of the left ventricle and chordae tendineae. In the extended configuration, the support is configured to project anteriorly with respect to a posterior wall of the left ventricle by a distance sufficient to position at least a portion of the posterior leaflet toward the anterior leaflet, and the appendage is configured to extend beyond an edge of the posterior leaflet toward the anterior leaflet.
One-piece heart valve stents adapted for post-implant expansion
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 is disclosed, together with methods of using same. The prosthetic heart valve may be configured to have a generally rigid and/or 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.
Systems and methods for reshaping a heart valve
The present disclosure includes a device for reshaping a heart valve. The device may include a central ring about a central axis and a plurality of arms coupled to the central ring, each of the arms coupled to the central ring at a pivot point at a first end of the arm, the arm comprising an attachment feature at a second point along the arm, the pivot point configured to allow movement of the arm about the pivot point through a plane extending radially from the central axis through the arm. Additionally, the plurality of arms may be contractable and may be extendable such that the hooks extend beyond a dilated heart valve. The present disclosure also includes associated methods and systems.

Implantable device and delivery system for reshaping a heart valve annulus
Systems, devices and methods related to various heart valve implants and for delivery of those heart valve implants are described. The implants may be used to re-size a native valve annulus or to replace a native heart valve. The implants include a re-sizable frame having angled struts. Anchors secure the implant to tissue and collars are used to decrease the angle between the struts and contract the frame. The implant thus expands from a first size inside of a delivery catheter, to a second and larger deployed size inside the heart to engage and anchor with the tissue, and then to a third and contracted size to re-size the annulus and/or provide a secure fit for a replacement heart valve. Various delivery systems including imaging capabilities for precise delivery, positioning and anchoring of the various implants are further described.
Delivering a constricting cord to a cardiac valve annulus using balloon-assisted positioning
A constricting cord can be delivered to the vicinity of an annulus using an apparatus that includes a set of support arms, with a respective anchor launcher supported by each of the support arms. An inflatable first balloon is configured to push the support arms away from each other when the first balloon is inflated. An inflatable second balloon is mounted to a shaft and is configured for inflation when the second balloon is disposed distally beyond the first balloon. In some embodiments, the distal balloon is inflated while it is in a ventricle. In some embodiments, the distal balloon is inflated while it is in a pulmonary artery.
Preventing dislodgement of a constricting cord that has been affixed to a cardiac valve annulus
Dislodgment of a constricting cord from an annulus can be prevented by delivering the distal loop portion of the constricting cord to the annulus using a percutaneous delivery tool, and launching anchors into the annulus so as to affix the distal loop portion of the constricting cord to the annulus. The percutaneous delivery tool is withdrawn in a proximal direction after the anchors have been launched. A pushing member is pressed in a distal direction so that the pushing member holds a portion of the constricting cord against the annulus with enough pressure to prevent dislodgment of any of the anchors during the withdrawal of the percutaneous delivery tool.
SYSTEMS AND METHODS FOR TARGET/ARTICLE BRIDGING ENGAGEMENT AND ANCHORING
A system for bridging a gap between an article or a portion thereof and a target, and anchoring the article or its portion to the target, the system comprising a) an elongated delivery catheter having a distal end; b) and a bridging and anchoring construction, operable to selectably translate in a distal and a proximal direction relative to the distal end of the elongated delivery catheter, the bridging and anchoring construction slidably coupled to the elongated delivery catheter, wherein the bridging and anchoring construction is operable to 1) engage the target following the distal translation spanning the gap between the article or its portion and the target; 2) eliminating the gap following the proximal translation; and 3) anchoring the article or its portion to the target.
Methods, Devices and Systems for Treating Venous Insufficiency
Methods and systems for improving the competency of a venous valve wherein one or more compressor(s) (e.g., space occupying material(s) or implantable device(s)) is/are delivered to one or more location(s) adjacent to a venous valve to compress the venous valve in a manner that causes one or both leaflets of the valve to move toward the other, thereby improving closure or coaptation of the valve leaflets. The compressor(s) may be delivered by an open surgical approach, by a direct percutaneous approach or by a transluminal catheter-based approach.
