Publication number: 20240058146Abstract: Through observation it has been determined that deployment of delivery sleeves may result in one or more portions of the deliver), sleeve extending beyond an end of the endoluminal device resulting in an overhang of material. The overhang may affect blood flow through the endoprosthesis or otherwise impact performance, including facilitating unwanted tissue growth. Various inventive concepts are provided for addressing (reducing or removing) constraining sheath overhang.Type: ApplicationFiled: December 28, 2020Publication date: February 22, 2024Inventors: Austin A. Byrne, Rebecca L. Maryn, Jilene M. Oakley, Michael J. Shepard

Publication number: 20220338980Abstract: Described embodiments are directed toward prosthetic valves having leaflets that move asymmetrically in that in the fully open position, the leaflet first side region opens less than the leaflet second side region. Asymmetric opening and final open position, in synchrony with the other leaflets having similar motion and final open position creates spiral flow exiting the open valve that may, among other things, increases blood flow on the downstream side of the leaflet and thus reduces stagnation of the blood that might lead to thrombus formation. Controlled asymmetric movement of the leaflet reduces closing volume by initiating closure on the leaflet first side region and finishing closures on the leaflet second side region.Type: ApplicationFiled: August 10, 2020Publication date: October 27, 2022Inventors: Kyle W. Colavito, Michael J. Shepard

Publication number: 20220226109Abstract: Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a valved conduit. The valved conduit may include a frame element arranged within the conduit and one or more expansion elements configured to spread apart to radially expand the frame.Type: ApplicationFiled: May 6, 2020Publication date: July 21, 2022Inventors: Kyle W. Colavito, Michael J. Shepard

Publication number: 20220133423Abstract: A medical device deployment apparatus that employs a first actuation line and a second actuation line, whereby a delay is sought between initiation of the actuation of the first actuation line and actuation of the second actuation line. Prior to actuation, the first actuation line includes sequentially aligned multiple loops, wherein the multiple loops provide predefined slack to delay linear actuation of the first actuation line when tension is applied to both the first and second actuation lines.Type: ApplicationFiled: February 22, 2019Publication date: May 5, 2022Inventors: Michael J. Shepard, James D. Silverman

Publication number: 20220000611Abstract: Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a prosthetic valve. The prosthetic valve may include a jacket configured to cover at least one of gaps, spaces, or interfaces in a frame or between one or more leaflets attached to the frame.Type: ApplicationFiled: September 16, 2021Publication date: January 6, 2022Inventors: David J. Arcaro, Kyle W. Colavito, Dustin V. Dienno, Cody L. Hartman, Roy Manygoats, JR., Ryan S. Titone, Ryan D. Smith, Joshua A. Sprinkle, Benjamin A. Smith, James L. Goepfrich, Michael J. Shepard

Patent number: 8556030Abstract: Improved acoustic attenuation materials and applications are provided. An improved acoustic attenuation material may include a woven layer of fibers made of porous polymers, such as porous polytetrafluoroethylene (PTFE), that include interstitial space. An improved acoustic attenuation material may include sheets of porous polymers interleaved with layers of epoxy. The sheets of porous polymers may include through holes. An embodiment of an ultrasonic transducer that includes a backing with woven layers of porous PTFE fibers is provided. The ultrasonic transducer that includes a backing with woven layers of porous PTFE fibers may be used in a three-dimensional ultrasound imaging apparatus. An embodiment of an ultrasonic transducer that includes a plurality of sheets of porous PTFE interleaved with layers of epoxy is provided. The ultrasonic transducer that includes a plurality of sheets of porous PTFE may be used in an ultrasonic imaging catheter.Type: GrantFiled: April 25, 2011Date of Patent: October 15, 2013Assignee: W. L. Gore & Associates, Inc.Inventors: Clyde Gerald Oakley, Michael J. Shepard, Michael J. Zipparo, Hermann Scholz
