Patent number: 11759200Abstract: Some disclosed suture securement devices comprise a flat, thin, generally planar body that has one or more suture engagement slots extending into the body from a perimeter inlet for receiving sutures laterally into the device. The slots can be resiliently widened to receive a suture and then released to clamp onto the suture. Some embodiments include two or more such suture engagement slots that independently receive and secure different sutures. Some embodiments include one or more locking tabs that have a closed position that retains the slots against widening and blocks the inlet to the slot. In some embodiment two or more slots are position next to each other on the same side of the device, while in other embodiments slots are positioned on opposite sides of the device. Other types of suture securement devices are also disclosed.Type: GrantFiled: November 11, 2019Date of Patent: September 19, 2023Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Manouchehr A.

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.

Publication number: 20220117730Abstract: Methods for the conditioning of bioprosthetic material employ bovine pericardial membrane. A laser directed at the fibrous surface of the membrane and moved relative thereto reduces the thickness of the membrane to a specific uniform thickness and smooths the surface. The wavelength, power and pulse rate of the laser are selected which will smooth the fibrous surface as well as ablate the surface to the appropriate thickness. Alternatively, a dermatome is used to remove a layer of material from the fibrous surface of the membrane. Thinning may also employ compression. Stepwise compression with cross-linking to stabilize the membrane is used to avoid damaging the membrane through inelastic compression. Rather, the membrane is bound in the elastic compressed state through addition cross-linking. The foregoing several thinning techniques may be employed together to achieve strong thin membranes.Type: ApplicationFiled: December 23, 2021Publication date: April 21, 2022Inventors: Jeffrey S. Dove, Bin Tian, Ralph Schneider, Jeffrey S. Cohen, Ivan Jankovic, John F. Migliazza, Gregory A. Wright, James M. Young, Louis A. Campbell
