Tricuspid valve repair system
First Claim
1. An interventional tissue clip device configured for repair of a cardiac valve, the clip device comprising:
- a pair of distal elements rotatably joined to a coupling member; and
a pair of proximal elements resiliently biased toward the pair of distal elements, the pair of distal elements being configured to receive the pair of proximal elements so as to enable the grasping of tissue therebetween, the pair of proximal elements including a plurality of adjustable tines moveable between a retracted configuration and an open configuration, the open configuration positioning the tines more perpendicular to respective longitudinal axes of the pair of proximal elements so as to enable enhanced grasping of tissue by the pair of proximal elements;
wherein the tines are coupled to one or more control lines, wherein adjusting tension of the one or more control lines controls movement of the tines between the open and retracted configurations.

Abstract
Devices and methods for use in a cardiac valve repair procedure, particularly a tricuspid valve repair procedure. An interventional clip device includes a pair of distal elements rotatably joined to a coupling member, and a pair of proximal elements resiliently biased toward the distal elements to grasp tissue therebetween. The proximal elements include a plurality of adjustable tines moveable between a retracted configuration and an open configuration to avoid damage to tissue prior to engagement while allowing tines to enhance gripping to targeted tissue when open. A delivery system enables delivery of an interventional clip to a targeted cardiac valve, and includes a support structure for maintaining position relative to the cardiac valve.
