The present invention relates to a tissue shaping device adapted to be disposed in a vessel near a patient's heart to reshape the patient's heart. The device comprises a first anchor and a second anchor adapted to be deployed by a catheter to engage a vessel wall while the first anchor is adapted to resist the compression of a first part of the first anchor and resist the expansion of a second part of the first anchor in response to a compressive force on the first part.

CARDIAC IMPLANT ANCHORING
20220079758 · 2022-03-17 ·

An implant comprises an anchor that comprises a helical tissue-coupling element. A tool is configured to advance the implant to a heart of a subject, and to position the anchor at tissue of the heart such that the implant extends from the anchor proximally away from the tissue. The tool comprises a tube having a distal end coupled to the implant, and a deployment manipulator. The deployment manipulator extends through the tube to the anchor disposed distally beyond the tube, and is configured to anchor the anchor to the tissue. Presence of the deployment manipulator through the distal end of the tube maintains the coupling between the distal end of the tube and the implant. Other embodiments are also described.

Devices and methods are disclosed for the treatment or repair of regurgitant cardiac valves, such as a mitral valve. An illustrative annuloplasty device can be placed in the coronary sinus to reshape the mitral valve and reduce mitral valve regurgitation. An improved protective device can be placed between the annuloplasty device and an underlying coronary artery to inhibit compression of the underlying coronary artery by the annuloplasty device in the coronary sinus. In addition, the protective device can inhibit compression of the coronary artery from inside the heart, such as from a prosthetic mitral valve that exerts radially outward pressure toward the coronary artery. The annuloplasty device can also create an artificial inner ridge or retaining feature projecting into the native mitral valve region to help secure a prosthetic mitral valve.
