A tissue gripping device is formed from a shape-memory material, and has a base section, a first arm, and a second arm disposed opposite the first arm, each arm having a first end coupled to the base section and a free end extending from the base section. The arms of the tissue gripping device are configured to resiliently flex toward a relaxed configuration in a distal direction as the tissue gripping device is moved from a pre-deployed configuration toward a deployed configuration. The tissue gripping device is usable in a method for gripping tissue. The method includes positioning the tissue gripping device near target tissue and moving the tissue gripping device from a pre-deployed configuration toward a deployed configuration in order to grip the target tissue.

Tissue grasping devices and related methods

The invention provides devices, systems and methods for tissue approximation and repair at treatment sites. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the abdomen, thorax, cardiovascular system, heart, intestinal tract, stomach, urinary tract, bladder, lung, and other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site. In addition, many of the devices and systems of the invention are adapted to be reversible and removable from the patient at any point without interference with or trauma to internal tissues.

System for fixation of leaflets of a heart valve

The present disclosure relates to repair devices, repair systems, and methods for repair of regurgitant tricuspid valves. A repair method includes positioning a repair device at a tricuspid valve. The repair device includes a pair of proximal arms and a pair of corresponding opposing distal arms, with each proximal arm and corresponding opposite distal arm forming an arm pair. The arms are actuated so that leaflet tissue is grasped between the proximal and distal arms, with a first leaflet being grasped by a first arm pair and a second leaflet being grasped by a second arm pair. A suture line is anchored at the second leaflet. Then, the repair device is pivoted to grasp and suture a third tricuspid leaflet to tie the second and third leaflets together. The clip remains deployed to tie the first and third leaflets together.

Gripper pusher mechanism for tissue apposition systems

A method for improving the function of a valve in the heart of a patient, comprising attaching, to a leaflet of the valve, an element that is responsive to a magnetic field; positioning, outside of the heart of the patient, a coil connected to a source of electric energy; activating the source of electric energy to provide an oscillating current in the coil; and thereby providing an oscillating magnetic field through the coil to effect movement of the element and the leaflet.
