Patent number: 11707280Abstract: Devices and methods for deploying self-cinching surgical clips. A device can access at least two layers of tissue or material from only one side of the tissue or material and puncture through the two layers of tissue or material. The various configurations of clips disclosed herein can be made of a superelastic material such as Nitinol, and have a constrained and a relaxed state, and no sharp edges or tips so as to reduce tissue irritation following deployment. The clip can be disposed within the housing of the delivery device and held in a constrained state until deployment wherein the clip assumes its relaxed state, where the ends of the clip can be brought into close approximation, thereby securing the layers of tissue or material together.Type: GrantFiled: August 17, 2021Date of Patent: July 25, 2023Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Brian S.
