Publication number: 20170202668Abstract: The invention relates to a device for treating a native valve comprising a body having two elongated segments, each elongated segment having a connecting end, both connecting ends being able to be bound to each other, and a traction end, the traction end including an attachment element for attachment to a traction system. Each traction end comprises a locking element.Type: ApplicationFiled: July 13, 2015Publication date: July 20, 2017Inventor: Mustapha LADJALI -
Publication number: 20170202669Abstract: A surgical instrument for treating atrioventricular valve prolapse of the drained human heart, includes a handle for being held by a surgeon, a shaft extending distally from the handle, the shaft having a lumen open to a shaft distal end, a cannulated needle arranged in the shaft; with a distal end of the needle protruding from the shaft distal end at least in one possible needle position. The needle accommodates a first, distal implant equipped for being anchored in a papillary muscle, and a second, proximal implant shaped to hold on to a leaflet of an atrioventricular valve, the first and second implants each including a chord connector portion for connecting the respective implant to an artificial chord. The apparatus further includes a trigger arrangement for releasing the first, distal implant upon a first release actuation and for releasing the second, proximal implant upon a second release actuation.Type: ApplicationFiled: July 9, 2015Publication date: July 20, 2017Inventors: Silvio Schaffner, Louis Weidmann, Rolf Vogel, Stefan Guggisberg, Andreas Mächler, Stijn Vandenberghe, Oliver Wüthrich, Thierry Carrel, Alberto Weber

Publication number: 20170202670Abstract: An implant for filling and/or distracting a body region, particularly a non-soft tissue cavity, has a plurality of segments wherein at least two of the segments are flexibly connected. The segments have a crush-strength sufficient to create and/or maintain the distraction of two or more non-soft tissue body surfaces, and to maintain the stability of the body region. The implant may be inserted into a cavity by an applicator having a cannula with a distal opening, and a rotary driver for applying force to move the implant within the cannula.Type: ApplicationFiled: December 23, 2016Publication date: July 20, 2017Inventor: Paul A. Zwirkoski

Publication number: 20170202671Abstract: A system includes a constrained acetabular insert, a dual mobility liner, and a femoral head. The constrained acetabular insert has its perimeter extending beyond hemisphere and the dual mobility liner has its perimeter extending beyond hemisphere and configured to tilt and rotate within the constrained acetabular insert. The femoral head is configured to tilt and rotate within the dual mobility liner. The constrained acetabular insert may include a plurality of tabs and the dual mobility liner may include screw threads for receiving the plurality of tabs.Type: ApplicationFiled: September 30, 2016Publication date: July 20, 2017Inventor: Michael Ries

Publication number: 20170202672Abstract: An artificial meniscus using a thermoplastic for the base material, which is reinforced with an inert material. In a preferred embodiment, the reinforcement is provided by Kevlar® fibers, and the matrix is made out of polycarbonate-urethane (PCU). In an alternate embodiment, the PCU can also be surrounded by a polycaprolactone (PCL) scaffold that is infused with human growth proteins so that when the artificial meniscus is implanted, stem cells in the body are stimulated to ensure the meniscus is properly secured.Type: ApplicationFiled: January 16, 2017Publication date: July 20, 2017Inventor: Philip A. Persaud

Publication number: 20170202673Abstract: An implant includes a fixed bearing, a floating bearing, and a coupling member. The fixed bearing defines a generally first spherical articulating surface and a stop. The floating bearing includes a second spherical articulating surface and a planar articulating bearing surface. The coupling member defines a bearing surface that translates relative to the planar articulating bearing surface.Type: ApplicationFiled: April 3, 2017Publication date: July 20, 2017Inventors: Nathan A. Winslow, John M. McDaniel

Publication number: 20170202675Abstract: An expandable implant device (100, 300, 600) for insertion between two vertebrae (400) is disclosed. The device (100, 300, 600) has a center body (10) one or more lift bodies (20, 40) and an external retaining band (60). The external retaining band (60) holds the sides (22, 42) of the one or more lift bodies (20, 40). The center body (10) has ramp surfaces (11) having a plurality or sets of ramps (11) sloped for allowing upward movement of the one or more lift bodies (20, 40). The sides (22, 42) have complimentary ramp surfaces that fit onto the ramps (11) of the center body (10). The height of the device (100, 300, 600) is increased by upward movement or downward movement or both of the one or more lift bodies (20, 40) driven by the lengthwise movement of the center body (10).Type: ApplicationFiled: March 29, 2017Publication date: July 20, 2017Applicant: Amendia, Inc.Inventors: Jeffrey Scott Radcliffe, Joshua David Gunn, Hansen A.
