Abstract: Systems and methods are disclosed for use with a valve of a heart. An implant (100) includes a wing (120); a flexible frame (124); and a pair of anchor receivers (150). A pair of shafts (660) are transluminally advanced through a catheter (40), while the shafts are each engaged with a respective anchor receiver (150), to deploy the implant out of the catheter such that the wing extends away from the anchor receivers and over a first leaflet of the valve and toward an opposing leaflet of the valve, with a contact face (122) of the wing facing the first leaflet. A pair of drivers (70) secure the implant using a pair of anchors (30) to anchor each anchor receiver to tissue at respective sites of the heart. Other implementations are also described.

Abstract: Devices and methods for securing a tissue anchor in tissue of a patient, in particular to ensure proper deployment of a cardiac tissue anchor by regulating the force or pressure of a deployment tool against the tissue. One way to ensure proper deployment force is to visualize the distal end of the tissue anchoring catheter from outside the body using a display for an imaging sensor, where the distal end of the catheter changes configuration when it is pressed against the tissue. Another method involves automatically regulating the pressure applied to the tissue prior to deployment of the tissue anchor, which may also be used in conjunction with visualization. Several safety locks to prevent deployment of the tissue anchor prior to establishment of the proper pressure are disclosed, which again may be used with visualization and/or an automated pressure regulator.
