MITRAL VALVE ANNULOPLASTY DEVICE WITH TWISTED ANCHOR

摘要

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.

主权项

1. A mitral valve therapy device, the therapy device comprising:
an expandable first anchor, an expandable second anchor, and an elongate body extending therebetween, the expandable first anchor having an anchored configuration, the expandable first anchor comprising a first segment and a second segment, and in the anchored configuration the first segment engages the second segment to form at least one full twist around the second segment in a central portion of the expandable first anchor in which the first segment passes over the second segment and then under the second segment and in which the second segment passes under the first segment and then over the first segment, the first and second segments forming a figure-8 configuration.
