Publication number: 20230380971Abstract: An implantable prosthetic device has a coaptation element and at least one anchor. The coaptation element is configured to be positioned within the native heart valve orifice to help fill a space where the native valve is regurgitant and form a more effective seal. The coaptation element can have a structure that is impervious to blood. The coaptation element can be connected to leaflets of the native valve by the anchor.Type: ApplicationFiled: August 14, 2023Publication date: November 30, 2023Inventors: Alex Philip McCann, Grant Matthew Stearns, Eric Robert Dixon, Yoon Hee Kwon

Patent number: 11344415Abstract: An exemplary valve repair device for repairing a native valve of a patient includes: a coaption element formed from a strip of material; a pair of extension members; a pair of paddles formed from the strip of material and connected to the coaption element; and a cap attached to the paddles. The paddles are movable between an open position and a closed position, are disposed over the extension member, and are configured to attach to the native valve of the patient. Movement of the cap toward the coaption element causes the pair of paddles to move to the closed position, and movement of the cap away from the coaption element causes the pair of paddles to move to the open position. The cap has a retention body for receiving attachment portions of the extension members, a retaining nut, and a retaining bolt for securing the retaining nut.Type: GrantFiled: February 20, 2019Date of Patent: May 31, 2022Assignee: Edwards Lifesciences CorporationInventors: Alex Philip McCann, Grant Matthew Stearns, Eric Robert Dixon, Yoon Hee Kwon

Publication number: 20220117728Abstract: An device for treating a native valve includes a sealing element and an anchoring element. The sealing element is made from a braided mesh material. The sealing element is dimensioned to be deployed in an annulus of a native valve of a heart at a position between native valve leaflets to contact the native valve leaflets during ventricular systole to create a seal to prevent regurgitation of blood from the left ventricle to the left atrium. The sealing element is configured to both be radially expanded and radially reduced while at the position between the native valve leaflets. The anchoring element is adapted for deployment in the heart, the anchoring element coupled to the sealing element and configured to support the sealing element at the desired position between native valve leaflets.Type: ApplicationFiled: October 29, 2021Publication date: April 21, 2022Inventors: Sergio Delgado, Lauren R. Freschauf, Eric Robert Dixon, Grant Matthew Stearns, Rachel Ann Gohres, Rachel Liat David Foreman, Alex Philip McCann, David M. Taylor

Patent number: 11147672Abstract: An exemplary valve repair device for repairing a native valve of a patient includes: a strip of material; a coaption element formed from the strip of material; a pair of paddles formed from the strip of material and connected to the coaption element; a cap attached to the paddles; and a pair of extension members connected to the cap and the paddles via attachment portions. The paddles are movable between an open position and a closed position and are configured to attach to the native valve of the patient. Movement of the cap toward the coaption element causes the pair of paddles to move to the closed position, and movement of the cap away from the coaption element causes the pair of paddles to move to the open position. The extension members extend to end portions attached to the strip material. The end portions extend beyond the strip of material.Type: GrantFiled: March 12, 2019Date of Patent: October 19, 2021Assignee: Edwards Lifesciences CorporationInventors: Alex Philip McCann, Grant Matthew Stearns, Eric Robert Dixon, Yoon Hee Kwon

Patent number: 11129717Abstract: An exemplary valve repair device for repairing a native valve of a patient includes: a strip of material; a coaption element formed from the strip of material; a pair of paddles formed from the strip of material and connected to the coaption element; a cap attached to the paddles; and a pair of extension members connected to the cap and movable between an open position and a closed position. The paddles are movable between an open position and a closed position and are configured to attach to the native valve of the patient. Movement of the cap toward the coaption element causes the pair of paddles to move to the closed position, and movement of the cap away from the coaption element causes the pair of paddles to move to the open position. In the closed position the extension members are biased in a closing direction.Type: GrantFiled: February 22, 2019Date of Patent: September 28, 2021Assignee: Edwards Lifesciences CorporationInventors: Alex Philip McCann, Grant Matthew Stearns, Eric Robert Dixon, Yoon Hee Kwon
