Patent number: 10792039Abstract: 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.Type: GrantFiled: November 18, 2019Date of Patent: October 6, 2020Assignee: ABBOTT CARDIOVASCULAR SYSTEMS INC.Inventors: Kent Dell, Theodore Ketai, Tanmay Mishra, Stephanie Jones, Jacob Greenberg, Michael Hong, Daniel Hale, Francisco Valencia, Steven Tyler
