Patent number: 11938027Abstract: An annuloplasty band and method of implantation. The band is shaped and sized to avoid the adjacent aortic valve structure and better protects against dehiscence along the muscular mitral annulus. The band is asymmetric and when implanted spans more around the side of the mitral annulus having the posterior commissure than the side with the anterior commissure. The band has a saddle shape with a posterior upward bow centered on a minor axis of the mitral annulus, and a span extending clockwise therefrom is longer than a span extending counter-clockwise. The longer span may be 150° while the shorter span extends 90°. A set of rings may have different saddle profiles and different plan view shapes for different sized bands. A method includes implanting so that the band extends over the posterior leaflet and a short distance past the posterior commissure outside of the anterior leaflet.Type: GrantFiled: October 14, 2022Date of Patent: March 26, 2024Assignee: Edwards Lifesciences, LLCInventor: David H.

Publication number: 20230285611Abstract: An apparatus for exposing a flat card to sanitizing radiant energy, has an enclosure that has an exposure chamber having a source of sanitizing radiation. A first insert slot and a second insert slot, disposed along an input surface of the enclosure are each configured to accept insertion of the flat card. A transport apparatus defines a first transport path to convey the flat card from the first insert slot, and through the exposure chamber, to emerge from a first output that opens on a first side surface of the enclosure and a second transport path to convey the flat card from the second insert slot, and through the exposure chamber, to emerge from a second output that opens on a second side surface of the enclosure that is opposite the first side surface.Type: ApplicationFiled: February 24, 2023Publication date: September 14, 2023Inventors: Robert G. Tegel, Turan Erdogan, David H. Adams

Publication number: 20220088242Abstract: An apparatus for exposing an article to radiant energy has a rotating carousel having an article support in a support sector defined between a first energy-blocking feature of the rotating carousel and a second energy-blocking feature of the rotating carousel. An actuator is energizable to rotate the carousel and to revolve the article support along a circular transport path. An enclosure has a stationary hood that defines an enclosed sector of the transport path and an unenclosed sector of the transport path. There is at least a first radiant energy source energizable to direct the radiant exposure energy toward the carousel along the enclosed sector of the transport path.Type: ApplicationFiled: September 10, 2021Publication date: March 24, 2022Inventors: Robert G.

Publication number: 20210161665Abstract: An annuloplasty ring for attachment to an annulus of a tricuspid valve comprises an elongate tube of suturable material comprising a central segment and first and second end segments. An arcuate stiffener is received in the central segment of the tube and extends the length thereof. The arcuate stiffener is circumferentially confined within the central segment to prevent circumferential movement of the stiffener relative to the tube. The first and second end segments of the tube lack a stiffener and are axially deformable.Type: ApplicationFiled: February 5, 2021Publication date: June 3, 2021Applicants: Medtronic ATS Medical, Inc., Medtronic, Inc.Inventors: David H. Adams, John T.M. Wright

Patent number: 9526615Abstract: Annuloplasty rings optimally sized to take into account more of the common degenerative valve pathologies. Each ring has a structural ring body with a shape that complies with predicted shapes of degenerative valvular diseases, such as fibroelastic deficiency (FED), Marfan's or Barlow's. The predicted shapes are obtained through careful echocardiographic and intraoperative measurements, and often differ for different annulus orifice sizes. For instance, in mitral rings the larger rings have larger minor axis and oblique axis dimensions relative to their major axis dimensions, and are more circular as opposed to D-shaped. The rings may also be three-dimensional and the relative heights around the rings may change for different sized rings. A mitral ring may have a higher anterior saddle relative to a posterior saddle, with the relative heights varying across the ring sizes. The ring may have varying flexibility around the ring periphery which also changes for different ring sizes.Type: GrantFiled: April 20, 2015Date of Patent: December 27, 2016Assignee: Edwards Lifesciences CorporationInventors: Alain F.
