First Claim
Patent Images
1. A method for repairing a heart valve leaflet in a patient, comprising:
- inserting a repair device into the patient to a position adjacent the heart valve leaflet;
deploying a first anchor into the heart valve leaflet at a first desired location, the first anchor having a first length of suture attached thereto;
deploying a second anchor into the heart valve leaflet at a second desired location spaced from the first desired location, the second anchor having a second length of suture attached thereto; and
tensioning the first and second lengths of suture to move the first and second anchors towards one another, whereby a plication is formed in the heart valve leaflet between the first and second desired locations.

Abstract
A repair device for repairing a heart valve leaflet in a patient includes a hollow body with a capture tool and a tissue puncture element at the distal end thereof. The capture tool may be used to capture and stabilize the heart valve leaflet tissue. The tissue puncture element may puncture the leaflet tissue and deploy at least one anchor having a length of suture attached thereto. By tensioning the suture, the leaflet tissue may become plicated. The tensioned suture may then be cinched to maintain the plication.
