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.
