Zusammenfassung: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.
