Patent number: 11944540Abstract: Described herein are devices and methods for mitral valve repair. The devices and methods implant a plurality of distal anchors at an annulus of the mitral valve (e.g., the posterior annulus) and tension artificial chordae to pull the portion of the annulus toward an opposite edge and inward into the ventricle. This can effectively reduce the size of the orifice and increase coaptation. The delivery devices can be configured to be actuated to form a distal anchor made of a pre-formed knot. The delivery devices deliver the pre-formed knot in an elongate configuration. Actuation of the delivery device causes the pre-formed knot to transition from the elongate configuration to the deployed configuration by approximating opposite ends of a suture coupled to a coiled configuration to form one or more loops. After formation of the knot, the delivery device can be withdrawn.Type: GrantFiled: September 4, 2020Date of Patent: April 2, 2024Assignees: University of Maryland, Baltimore, Harpoon Medical, Inc.Inventors: Michael Nicholas D'ambra, Felino V. Cortez, Jr., James S. Gammie, Peter Wilson, Stephen Epstein, Stephen Cournane, Julie Marie Etheridge, Peter Boyd

Publication number: 20240099845Abstract: Described herein are methods and apparatus for approximating targeted tissue using locking sutures. The locking sutures can be configured to receive suture ends that are interweaved through portions of the locking sutures. In a pre-deployment configuration, a locking suture can slide along suture tails and can be positioned at a target location within a target region. Once a desired position and/or tension is achieved, the locking suture can be transitioned to a post-deployment configuration where the locking suture constricts around the suture tails to inhibit relative movement between the suture tails and the locking suture. A visualization system can be used to provide visual feedback with respect to approximating the targeted tissue and the locking sutures.Type: ApplicationFiled: December 4, 2023Publication date: March 28, 2024Inventors: Felino V.

Publication number: 20220265426Abstract: A medical device shaft includes a rigid, elongate shaft, an end effector form coupled to a distal end of the elongate shaft, and echogenic additives associated with at least one of the elongate shaft and the end effector. The shaft exhibits improved echogenicity, and is suitable for devices that are manipulated or positioned with under echo guidance.Type: ApplicationFiled: March 1, 2022Publication date: August 25, 2022Inventors: Felino V.

Patent number: 10765515Abstract: Described herein are devices and methods for mitral valve repair. The devices and methods implant a plurality of distal anchors at an annulus of the mitral valve (e.g., the posterior annulus) and tension artificial chordae to pull the portion of the annulus toward an opposite edge and inward into the ventricle. This can effectively reduce the size of the orifice and increase coaptation. The anchor points of the artificial chordae can be offset from the apex of the heart to achieve a targeted force vector on the annulus. In addition, some embodiments include distal anchors implanted in the posterior leaflet in addition to those at the posterior annulus. This allows differential tensioning to be applied to provide for greater flexibility in treating various configurations of mitral valves to improve coaptation.Type: GrantFiled: April 11, 2018Date of Patent: September 8, 2020Assignees: University of Maryland, Baltimore, Harpoon Medical, Inc.Inventors: Michael Nicholas D'ambra, Felino V.
