Publication number: 20170007401Abstract: An adjustable annuloplasty device (1) comprising a tube (2) having a basically annular shape or adopted to be brought into an annular shape. At least one portion, preferably three portions, of an outer wall (3) or the whole outer wall of the tube (2) is more rigid than opposite portion(s) of an inner wall (4) or the whole inner wall (4). The inner wall is arranged nearer to an inside (5) area defined by the annular shape than the outer wall (3). The inner wall (4) is adapted to be displaced inwardly at least along less rigid portion(s) of the circumference upon actuation by at least one actuation element (10) while the outer wall (4) remains basically constant.Type: ApplicationFiled: January 29, 2015Publication date: January 12, 2017Inventor: Daniel HAYOZ

Publication number: 20170007402Abstract: A medical device for delivering and retrieving a medical implant is disclosed comprising a sheath, a wire having a distal end and being movable in a lumen of the sheath in a longitudinal direction of the sheath. The distal end comprises a locking structure for receiving and interlock with a complementary mating surface of a medical implant, wherein the locking structure comprises a first locking surface aligned in a first radial direction to lock rotational movement of the implant, when received in the locking structure, around the longitudinal direction. The wire comprises a pivotable locking portion having an open and a closed position, the locking portion has a locking structure with a recess locking movement of the implant, when received in the locking structure, in the longitudinal direction, when the locking portion is in the closed position.Type: ApplicationFiled: February 18, 2015Publication date: January 12, 2017Inventors: Hans-Reinhardö Zerkowski, Ger O'Carroll, Mark Pugh

Publication number: 20170007404Abstract: A method of implanting a cardiac device featuring the insertion of an inner seal member through an opening in a pericardium about a living human heart. The inner seal member has a first sealing lip disposed inside the pericardium and surrounding an aperture through the inner seal member. An outer seal member is aligned with the inner seal member. The outer seal member has a second sealing lip disposed outside the pericardium, surrounding an aperture through the outer seal member. The inner seal member is secured to the outer seal member. The firsts sealing lip is engaged against an inner surface of the pericardium. The second sealing lip is engaged against an outer surface of the pericardium. A cardiac device is inserted into the pericardium through the apertures of the inner and outer seal members.Type: ApplicationFiled: December 29, 2015Publication date: January 12, 2017Inventors: Stephen Manuel Wildhirt, Andreas Maier

Publication number: 20170007405Abstract: A device 10 for repairing mitral valve leaflets 2, 3 includes a jaw mechanism 15 that may be positioned adjacent a mitral valve leaflet 2, 3. The jaw mechanism 15 may move between an open position and a closed position by pivoting a first jaw relative 16 to a second jaw 18. The first jaw 16 may include a rivet 28 that may move from a stored position to an application position projecting away from the first jaw 16 when the jaw mechanism 15 is moved from the closed to the open position. Closing the jaws 16, 18 about a valve leaflet 2, 3 causes the rivet 28 to pierce the leaflet. The jaw mechanism 15 may then be rotated to wind the leaflet 2, 3 thereabout and again pierce the leaflet. The rivet 28 may then be released from the jaw mechanism 25 and the device 10 removed from the patient.Type: ApplicationFiled: September 23, 2016Publication date: January 12, 2017Inventors: Mark Griffin, Benjamin E. Morris, Eric E. Bielefeld, Gregory R. Furnish, Wayne Johnson
