Abstract:
A prosthetic arm apparatus including a plurality of segments that provide a user of the prosthetic arm apparatus with substantially the same movement capability and function as a human arm. The segments are connectable to one another and connectable to a prosthetic support apparatus that may be adorned by the user. Each segment of the plurality of segments provides a portion of the movement capability, enabling the plurality of connected segments connected to the harness mount to provide substantially the same movement capability as that lacking in the user. A dynamic support apparatus for supporting the prosthetic arm apparatus has a frame, a dynamic interface, a temperature control mechanism, and a control system. The dynamic support apparatus has a control system that is operably connected to the dynamic interface and controls the dynamic interface to change its geometry.
Abstract:
An adjustable height intervertebral implant for total, partial, or nucleus replacement of an intervertebral disc space includes an upper endplate for contacting a first vertebra, a lower endplate for contacting a second vertebra and a mechanism for moving the upper endplate with respect to the lower endplate so that once the implant is inserted into an intervertebral disc space, the implant can be expandable from a first insertion configuration to a second expanded configuration. The mechanism for moving the upper endplate with respect to the lower endplate preferably includes a plurality of telescopic gear sets. The telescopic gear sets may be directly connected to one another or may be indirectly connected to one another by, for example, a pinion gear.
Abstract:
A plug system (10', 10, 10") for preventing material from extruding beyond a desired location in a bone tunnel (42) includes a plug member (20', 20, 22") that has an insertion axis (2, 4, 206') extending from a first end (202', 202, 202") and a plurality of interleaving arms (205', 205, 205") disposed about the insertion axis. The arms (205', 205, 205") are affixed at a second end (204', 204, 204") and are flarable at the first end (202', 202, 202") between an insertion position wherein the arms (205', 205, 205") are relatively close packed and a position wherein the arms (205', 205, 205") are flared. A portion of each arm (205', 205, 205") remains in overlapping relation to an adjacent arm (205', 205, 205"). The system (10', 10, 10") further includes an expansion member (32, 30, 31) that has an insertion portion (321, 301, 311) adapted to separate the arms (205', 205, 205") upon progressive entry along the insertion axis (2, 4, 206') from the first end m(202'. 202. 202"). In use the plug (20', 20, 20") can be inserted either first end (202', 202, 202") first, with the expansion member (32, 30, 31) drawn into the plug (20', 20, 20") by a manipulator (33, 50), or second end (204', 204, 204") first, with the expansion member (32, 30, 31) driven along the insertion axis (2, 4, 206').
Abstract:
Die Erfindung betrifft eine modulare Femurkopfprothese umfassend einen Schaftteil (1) zum Einsetzen in einem meduläre Öffnung eines Femurs und einen Halsteil (2) mit einer Aufnahmefläche (25), der auf einer Stützfläche (15) im Endbereich des Schaftteils (1) mittels eines Verschraubungselements (3) befestigbar ist. Erfindungsgemäß ist mindestens ein gesonderter Zwischenring (4) vorgesehen, der zwischen der Stützfläche (15) des Schaftteils (1) und der Aufnahmefläche (25) des Halsteils (2) angeordnet und mittels des Verschraubungselements (3) fixiert ist. Damit wird erreicht, dass Femurkopfprothesen unterschiedlicher Größe durch einfaches Auswechseln eines Bauelements auf einfache Weise bereitgestellt werden können. Sie ermöglichen dem Operateur eine Anpassung der Länge der Prothese auch an intraoperativ aufgefundene Schwierigkeiten.
Abstract:
Various embodiments of the present invention relate to an apparatus and method for reverse shoulder arthroplasty (e.g., reverse total shoulder arthroplasty). In one specific example, a glenoid component used to resurface the scapula may be provided. Of note, unlike traditional total shoulder arthroplasty the glenoid component in a reverse shoulder is convex rather than concave; it acts as a physical stop to prevent the superior migration of the humeral head - a typical occurrence in patients suffering from rotator cuff tear arthropathy (CTA).
Abstract:
A transcutaneous prosthesis is disclosed comprising a first component (1) shaped for implantation into a bone (2), a second component (4) intended for location between the bone (2) and the skin, and a third component (5) intended for location exterior to the skin surface, having a low surface energy which deters bacterial adhesion. The second component (4) may carry an adhesion-promoting protein.
Abstract:
A high density actuator, comprising a housing assembly composed of a first housing element containing a motor stator and a second housing element containing a gear reduction mechanism, a rotational core positioned at the center of the housing assembly, the rotational core being composed of a motor rotor and a transmission input operatively connected to the motor rotor, a transmission output positioned between the transmission input and the housing assembly, the transmission output forming an actuator output, a torque transfer output operatively connected to the actuator output and a center shaft connected to the torque transfer output in its center and in rotational contact with the first housing element, the center shaft passing through the transmission output, rotational core and second housing element to ensure proper radial and axial alignment.
Abstract:
A prosthetic arm apparatus including a plurality of segments that provide a user of the prosthetic arm apparatus with substantially the same movement capability and function as a human arm. The segments are connectable to one another and connectable to a prosthetic support apparatus that may be adorned by the user. Some segments may provide movement about more than one axis using a single actuator. The prosthetic arm apparatus may include a user interface incorporated therein and may include one or more communication systems for communicating with external devices.

Abstract:
Methods and devices are provided for measuring and/or controlling an amount of force applied to an implant or other element. In certain exemplary embodiments, an implant inserter tool is provided that includes a shaft having a proximal end that is adapted to receive a force and a distal end that is adapted to contact an implant. The inserter tool also include a force controlling element coupled to the shaft. In use, the distal end of the tool can be placed in contact with an implant or other element, and a force can be applied to the proximal end of the tool to drive the implant or other element into bone. The force controlling element can measure the amount of force applied to the inserter tool, thereby measuring the force applied to the implant or other element.
