Patent number: 11141284Abstract: An implant couples a first bone of a hand to a second bone of the hand. The implant includes a body that defines a median plane. The body also defines a first joint surface having a first central region that articulates with the first bone. The body further defines a second joint surface having a second central region that articulates with the second bone, and the second central region is disposed on an opposite side of the median plane of the body relative to the first central region. The first and second central regions correspond to profiles of first and second axial segments, respectively, the first and second axial segments are each one of a cylinder, a cone and a torus and are centered on first and second axes, respectively, and the first and second axes, as projected on the median plane, are substantially perpendicular to each other.Type: GrantFiled: September 19, 2019Date of Patent: October 12, 2021Assignee: TORNIERInventors: Michel Hassler, Philippe Bellemere

Patent number: 9161789Abstract: A method for fusing a joint, which includes the step of inserting a first anchoring zone of an arthrodesis device being in a first closed position into a first opening within a first bone. The first anchoring zone includes a first pair of legs. Each leg is capable of transitioning between the first closed position and a first open position for internally gripping the first opening. Also, included in the method is the step of inserting a second anchoring zone of the arthrodesis device being in a second closed position into a second opening within a second bone. The second anchoring zone includes a second pair of legs. Each leg is capable of transitioning between the second closed position and a second open position for internally gripping the second opening.Type: GrantFiled: May 13, 2013Date of Patent: October 20, 2015Assignee: MEMOMETAL TECHNOLOGIESInventors: Jacques Peyrot, Tristan Meusnier, Bernard Prandi, Philippe Bellemere, Marc Augoyard

Patent number: 8858644Abstract: An orthopaedic implant used in arthroplasty of the fingers comprises a first element for a proximal phalanx and a second element for an adjacent distal phalanx, each element having a respective stem for implantation in the bone and an interphalangeal articulation head, the head of the first element having a biconvex surface of articulation, with a central valley, and the head of the second element having a biconcave surface of articulation designed to cooperate with said convex surface and comprising a central crest. At rest, the surfaces are congruent in the frontal plane of the articulation in the area of the condyles and non-congruent in the sagittal plane.Type: GrantFiled: January 8, 2010Date of Patent: October 14, 2014Assignee: Memometal TechnologiesInventors: Jean Goubau, Xavier Martinache, Michaël Papaloïzos, Philippe Bellemere, Thierry Dreano, Bernard Prandi, Pierre Siret, Alain Tchurukdichian
