Patent number: 10034751Abstract: A delivery system for an implantable medical device having at least one retention member at an end thereof includes a shaft extending in a longitudinal direction. An elongated sheath surrounds the shaft. The sheath is slidable relative to the shaft in the longitudinal direction. A space is defined inside of the sheath and is adapted to receive the medical device in an assembled or collapsed condition. A retainer is positioned at a first end of the space. At least one recess is provided in the retainer and is adapted to receive the retention member of the medical device in the assembled condition. A selectively activable member is disposed in the compartment between the longitudinal shaft and the medical device. When in an activated state, the member expands radially relative to the shaft, thereby urging the retention member to disengage from the recess.Type: GrantFiled: May 12, 2016Date of Patent: July 31, 2018Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Valerie J.

Patent number: 10028828Abstract: Methods and apparatus for holding and maneuvering a valve during preparation and attachment to patient, providing increased visibility of the prosthetic valve and the sewing ring to prevent suture entanglement. A handle attachment is spaced from the valve for improved visibility of the sewing ring and the outlet end of the valve during attachment. Commissure posts are bent inward at the tips while preventing crashing of the commissure posts into each other causing damage. A release force needed to remove the holder and unthread the holder sutures is reduced. The holder and related methods can provide a kink free holder suture path to reduce suture entanglement and prevent damage to the implanted valve during holder removal by reducing the release force needed to remove the holder sutures by up to 30%.Type: GrantFiled: August 12, 2016Date of Patent: July 24, 2018Assignee: Medtronic, Inc.Inventors: Cathy A. Bergin, Timothy R. Ryan

Patent number: 10010414Abstract: Embodiments of a prosthetic heart valve comprise an annular main body, an atrial cap extending radially outwardly from the atrial end of the main body, and a plurality of ventricular anchors extending outwardly from the ventricular end of the main body. Each ventricular anchor can have a proximal end portion connected to the ventricular end, an intermediate portion extending away from the atrial end and then back toward the atrial so as to define a first bend, and a free distal end portion that extends from the intermediate portion. The distal end portion can comprise a first section, a second section, and a second bend between the first and second sections, the first section extending from the intermediate portion in a direction toward the atrial end and radially away from the main body.Type: GrantFiled: December 16, 2016Date of Patent: July 3, 2018Assignee: Edwards Lifesciences CorporationInventors: Alexander H. Cooper, Matthew A. Peterson, William C. Brunnett

Patent number: 10010417Abstract: In one representative embodiment, a prosthetic valve assembly comprises a valve component comprising a radially compressible and expandable frame and a valve structure supported inside of the frame. The valve structure is configured to allow blood to flow through the valve component in one direction and block the flow of blood in the opposite direction. The assembly further comprises a radially compressible and expandable anchor comprising an annular base and a plurality of cantilevered fixation members extending from the base. The fixation members are configured to pivot inwardly toward the valve component when the valve component is radially expanded within the anchor.Type: GrantFiled: April 15, 2016Date of Patent: July 3, 2018Assignee: Edwards Lifesciences CorporationInventor: Yaron Keidar

Patent number: 10004600Abstract: A device for supporting soft tissue includes a tubular body and is constituted of a sequence of compliant portions and anchoring portions. The anchoring portions each include anchor members adapted to penetrate into soft tissue. The compliant portions each include deformable members extending between ends of the compliant portion, at least one of a distance and orientation between said ends being adjustable by application of a force on the tubular body. The tubular body includes a ring-like shape reached at least by deformation of the compliant portions, the ring-like shape having the anchor members of the anchoring portions protruding circumferentially along a direction defined by a vector having a component being at least tangential to the curve of the ring-like shape, for the anchor members to penetrate the soft tissue. A method for anchoring the device to soft tissue is also provided.Type: GrantFiled: May 2, 2013Date of Patent: June 26, 2018Inventors: Renzo Cecere, Rosaire Mongrain, Toufic Azar, Jorge Angeles, Jozsef Kovecses

Patent number: 9999503Abstract: The invention is a system and method for accurately positioning a prosthetic valve such as a prosthetic heart valve at a desired position for deployment. The invention includes extendable positioning elements which provide tactile feedback to a user to confirm proper positioning of the catheter with respect to the native valve annulus. During delivery, the extendable positioning elements lie against the catheter, over the prosthetic valve and expandable balloon, providing a low profile for advancing the catheter to the desired treatment location via small passages such as body lumens. Prior to valve deployment, the positioning elements are extended and brought into contact with tissue of the native annulus to confirm the proper positioning of the delivery system and prosthetic valve.Type: GrantFiled: June 29, 2016Date of Patent: June 19, 2018Assignee: Edwards Lifesciences CorporationInventors: Francis G. Duhay, David L. Zollinger

Patent number: 9980816Abstract: Disclosed prosthetic valves can comprise a sewing ring configured to secure the valve to an implantation site. Some disclosed valves comprise a resiliently collapsible frame having a neutral configuration and a collapsed deployment configuration. Some disclosed frames can self-expand to the neutral configuration when released from the collapsed deployment configuration. Collapsing a disclosed valve can provide convenient access to the sewing ring, such as for securing the valve to the implantation site, as well as for the insertion of the valve through relatively small surgical incisions. Examples of delivery systems and methods for deploying the valves exhibit reduced patient trauma.Type: GrantFiled: March 19, 2015Date of Patent: May 29, 2018Assignee: Edwards Lifesciences CorporationInventors: Hengchu Cao, Brian S.

Patent number: RE47065Abstract: An improved holder and method for implanting a tissue-type prosthetic mitral heart valve that prevents suture looping and ma y also constrict the commissure posts of the valve. An upstanding or shaft member axially positioned on the holder causes the lengths of attachment sutures to extend axially beyond the commissure post tips to create a tent and prevent looping of any of an array of pre-implanted sutures around the tips during deployment of the valve. The shaft member may be axially movable such that it can be initially retracted and then actuated just prior to valve deployment. The shaft member may have notches on its distal tip for capturing the attachment sutures, which are crossed over along the valve axis to ensure engagement by the notches. The attachment sutures may be strands or filaments, or may be wider bands of flexible biocompatible material. If bands are used, they desirably cover the commissure post tips to further help prevent suture looping thereover.Type: GrantFiled: August 11, 2016Date of Patent: October 2, 2018Assignee: Edwards Lifesciences CorporationInventors: Robert Stobie, Ralph Kafesjian, Diana Nguyen-Thien-Nhon, Robert Ian Lister, Andrzej Skoskiewicz, Adrian Benton James, Aaron Ernesto Sklar, Banny Banerjee
