Patent number: 9060866Abstract: A knee joint endoprosthesis (1) for forming an articulation between a femur and a tibia includes a femur component (2), which is connected to the femur, a tibia component (4), which is connected to the tibia, and an intermediate element (3) which is mounted between the tibia component (4) and the femur component (2). This intermediate element lies against the femur component (2) with a modular sliding surface (9) which includes a lateral sliding surface (9a) and a medial sliding surface (9b), and can be connected in a releasable manner to the tibia component (4). The lateral sliding surface (9a) and the medial sliding surface (9b) of the intermediate element (3) have different sagittal cross-sectional profiles.Type: GrantFiled: November 28, 2005Date of Patent: June 23, 2015Assignee: MATHYS AG BETTLACHInventors: Christoph Fankhauser, Walter Supper, Daniel Delfosse, Tobias Wyss

Publication number: 20120136359Abstract: A device for the implementation of osteotomies on the distal femur in knee-joint replacement surgery with a base element (11), which comprises an anterior cutting-guide block (12) disposed on the base element (11), which specifies an anterior section plane (14), and a posterior cutting-guide block (13) disposed on the base element (11), which specifies a posterior section plane (16). In this context, the distance between the anterior section plane (14) and the posterior section plane (16) is variable.Type: ApplicationFiled: October 28, 2010Publication date: May 31, 2012Inventors: Beat Grunder, Christoph Fankhauser, Walter Supper

Patent number: 7651500Abstract: A ligament tensing device (1) for activating a ligament and/or capsule system during implantation of a joint implant, comprising a base body (2) having a first lug (3) with a distal bearing surface (4) resting upon a first bone, and a second lug (7) resting upon a second bone with a proximal bearing surface (10) thereof. The second lug (7) is displaceable in an anterior-posterior and/or medial-lateral direction parallel to the first lug (3).Type: GrantFiled: July 1, 2003Date of Patent: January 26, 2010Assignee: Mathys AG BettlachInventors: Walter Supper, Christoph Fankhauser, Beat Grunder, Daniel Delfosse, Ulrich Wehrli

Publication number: 20070293868Abstract: A ligament-tensioning device (1) for preparing the implantation of an articulated implant consists of a base body (5) comprising first claws (6, 6?) provided with first bearing surfaces (7, 7?) applied to a first bone part (33) and second claws (13, 13?) provided with a second bearing surfaces (10, 10?) applied to a second bone part (34). The claws (6, 6?; 13, 13?) are displaceable with respect to each other with the aid of parallel-displacement devices (12, 12?). In addition, the invention provides for a first scale (31) disposed on the base body (5) of the ligament-tensioning device (1) and second medial and lateral scales (32, 32?) corresponding to the first scale (31), wherein the second scales (32, 32?) are disposed on a guiding body (3) which is movably mounted with respect to said base body (5) by means of the parallel-displacement devices (12, 12).Type: ApplicationFiled: October 18, 2005Publication date: December 20, 2007Inventors: Daniel Delfosse, Walter Supper, Christoph Fankhauser

Patent number: 7244274Abstract: The invention relates to a joint prosthesis, especially a knee joint prosthesis, for establishing an articulated connection between a first bone and at least one second bone. The inventive prosthesis comprises a first component (1) that is at least indirectly linked with the first bone, at least one second component (2) on which the second bone at least indirectly supports itself and which is movably mounted on at least one bearing surface (22) of the first component (1), and a connecting element (4) that interlinks the first component (1) with the second component (2). The connecting element (4) comprises an elastically deformable element (5) that facilitates a deflection of the first component (1) relative to the second component (2) from an initial position. When the first component (1) is deflected, the elastically deformable element (5) generates a restoring force that acts upon the first component (1) and restores the first component (1) to the initial position.Type: GrantFiled: February 25, 2002Date of Patent: July 17, 2007Assignee: Mathys Medizinaltechnik AGInventors: Daniel Delfosse, Walter Supper, Beat Grunder

Patent number: 7105027Abstract: A prosthesis for repairing a knee is made with an insert sandwiched between a femoral component and a tibial tray. The parts are shaped so that both the femoral component and the tibial tray will slidingly interface with the insert during motion of the knee. At regions where the femoral component interfaces with the insert during extension and during an initial range of flexion of the knee, the femoral component's radius of curvature (R1) for flexion rotation is larger than its radius of curvature (R3) for varus/valgus rotation. In a preferred embodiment, the surface of the tibial tray is convex and spherically curved, and the insert is free to move in both the posterior-anterior direction and the medial-lateral direction with respect to the tibial tray.Type: GrantFiled: January 31, 2003Date of Patent: September 12, 2006Assignee: Mathys Medical Ltd.Inventors: Joseph D. Lipman, Russell F. Warren, Thomas L. Wickiewicz, Timothy M. Wright, Donald L. Bartel, Frank Hoffman, Christoph Fankhauser, Daniel Delfosse, Walter Supper

Publication number: 20050256527Abstract: A ligament-tensioning device for preparing for the implantation of a joint implant has a base body, having a first claw with a distal bearing surface which rests on a first bone, and a second claw which rests, with a proximal bearing surface, against a second bone. The second claw is displaceable parallel to the first claw. A cutting jig can be placed onto mounts of the base body of the ligament-tensioning device.Type: ApplicationFiled: February 26, 2003Publication date: November 17, 2005Inventors: Daniel Delfosse, Walter Supper, Beat Grunder
