Patent number: 10925610Abstract: An aspect of the present teachings includes a method of percutaneously treating a paravalvular leakage. In a preferred embodiment, the method includes providing an anchor having an elongate anchor member and a tensioning member, positioning the anchor through a paravalvular leakage, deploying the anchor wherein at least a part of the distal portion of the elongate anchor member is on one side of the paravalvular leakage, and applying tension to the tensioning member so that at least a part of the distal portion of the elongate anchor member transitions from the elongate configuration to the shortened configuration. Another aspect of the present teachings includes a device that can be used in a method of percutaneously treating a paravalvular leakage.Type: GrantFiled: January 16, 2019Date of Patent: February 23, 2021Assignee: Edwards Lifesciences CorporationInventors: Steven Cahalane, Jason Robinson

Patent number: 10828160Abstract: The present teachings provide devices and methods of treating a tricuspid valve regurgitation. Specifically, one aspect of the present teachings provides devices each includes a vascular anchor, an annulus anchor, and at least one tensioning member connecting with the vascular anchor or the annulus anchor. Another aspect of the present teachings provides methods of deploying a vascular anchor at a first treatment location inside the coronary sinus, and deploying an annulus anchor at a second treatment location across the tricuspid annulus. When both the anchors are pulled towards each other, the portion of the annulus between the two anchors is plicated, which improves the coaptation of the tricuspid valve leaflets.Type: GrantFiled: December 29, 2016Date of Patent: November 10, 2020Assignee: Edwards Lifesciences CorporationInventors: Michael Sutherland, Steven Cahalane

Patent number: 10751182Abstract: The present teachings provide devices and methods of reshaping the right heart and reducing tricuspid valve regurgitation. Specifically, one aspect of the present teachings provides an inflatable device to be deployed in the space between the sternum and the right heart. An injectable medium is injected to the cavity of the device. Once the device is filled, the device is detached from the delivery system, and released inside the body. The inflated device exerts pressure to the right heart, changes the shape of the tricuspid annulus, and allows a better coaptation of the tricuspid leaflets.Type: GrantFiled: December 29, 2016Date of Patent: August 25, 2020Assignee: Edwards Lifesciences CorporationInventors: Michael Sutherland, Steven Cahalane, Morgan House

Patent number: 8968335Abstract: A tissue anchoring system includes a tissue anchor member that is suitable for anchoring against tissue. The system also includes a tensioning member operatively connected to the anchor member such that the anchor member can slide relative to the tensioning member, the tensioning member capable of being pulled to cause the anchor member to move relative to the tensioning member into a position seated against the tissue. A hand operated deployment catheter is operable to extend and deploy the anchor member therefrom. The deployment catheter includes a rotatable member about which the tensioning member is routed and a clutch assembly for limiting tension within the tensioning member to prevent the deployed anchor from being pulled through the tissue.Type: GrantFiled: October 26, 2011Date of Patent: March 3, 2015Assignee: Mitralign, Inc.Inventors: Jason H.
