20230416891 · 2023-12-28 ·

The present invention is directed to a biodegradable alloy suitable for use in a medical implant, comprising at least 50% iron by weight, at least 25% manganese by weight, and at least 0.01% sulfur and/or selenium by weight, wherein the biodegradable alloy is nonmagnetic. The present invention also provides a method of producing a biodegradable alloy with a desirable degradation rate.

PATELLA TENDON REALIGNMENT IMPLANT WITH FIXATION

An orthopedic implant system including an orthopedic implant with an inferior portion having a surface configured to extend over a top surface of a tibia; a superior portion opposite to the inferior portion and configured to change a position of a patellar tendon by lifting or tilting the patellar tendon when the surface of the inferior portion is engaged with the tibia; a first lateral side disposed between the inferior portion and the superior portion; and a second lateral side disposed between the inferior portion and the superior portion opposite to the first lateral side; and a fixation system to attach the orthopedic implant to the tibia. The invention also includes corresponding methods.

Modular Rotational Device For Torsionally Stabilizing An Endoprosthesis
20200297500 · 2020-09-24 ·

An improved modular rotational device includes a first and second threaded coupler for affixation along the stem of an endoprosthetic device, for example, a humeral prosthesis or a femoral prosthesis. The rotational device axis of rotation is coaxial with the stem, and its axis of rotation is located in close proximity to the intramedullary stem of the prosthesis or in close proximity to the distal articulation of the prosthesis. A housing has a proximal and distal end with an axial bore therethrough for receiving an elongated stem of the device. A lobe ring may be utilized to limit the axis of rotation of the device. Additional endoprosthetic devices may be attached to male or female threaded couplers, or to Morse tapers. A plurality of suture attachments facilitates attachment of soft tissue thereto.

Flush anchor snap-off apparatus

An anchor for tensile member(s) includes: a housing having a hollow interior; a collet in the hollow interior of the housing, the collet having a peripheral wall defining a central bore and an exterior surface. The collet is configured to be swaged around the tensile member(s). The collet includes longitudinal grooves in an outer surface of the peripheral wall, each defining a web configured to collapse inward in response to external compressive force. A sleeve has a peripheral wall defining interior and exterior surfaces and is disposed in the housing axially adjacent to the collet. At least one of the collet and the sleeve is tapered and the sleeve and the collet are arranged such that sleeve movement from a first position to a second position will cause the sleeve to bear against the collet, swaging the collet radially inwards around and against the tensile member(s).

Cable-lock for orthopedic cables
10667853 · 2020-06-02 · ·

A cable-lock device includes a housing, having a length-axis between a distal end for accepting a cable and a proximal end for exiting a cable, including a first bore parallel to the length-axis of the housing and configured to allow passage of the cable, a second bore off-center from and parallel to the first bore including a tappet axially displaceable in the second bore and parallel to the length axis of the housing, and a third bore oblique to the first bore which intersects with the first bore including a locking roller axially displaceable in the third bore with a predetermined angulation to the length-axis of the housing, a resilient structure which exerts a force on the locking roller in the direction of the intersection of the first bore and the third bore, and a fastener unit at the proximal end of the third bore.

CONNECTIVE TISSUE TO BONE INTERFACE SCAFFOLDS

Connective tissue-to-bone interface scaffolds (e.g., ligament-to-bone interface scaffolds, tendon-to-bone interface scaffolds, etc.). These scaffolds may be a single integrated implant or may be a modular (e.g., two-part) implant system.

Prosthesis Surface Treatment For Soft Tissue Attachment Thereto
20200054457 · 2020-02-20 ·

The improved endoprosthetic device surface treatment encourages soft tissue attachment thereto. A porous mesh surface treatment creates on an outer surface of the endoprosthetic device a three-dimensional surface structure similar to cancellous bone. Suture attachment features are provided at various locations around the treated surface structure to initially affix a vascularized soft tissue to the treated surface. As the patient heals the soft tissue grows and infiltrates the porous mesh surface to achieve an attachment strength substantially equal to the surrounding tissue.

Flush anchor snap-off apparatus

An apparatus for anchoring one or more tensile members to bone includes: an anchor, including: a housing having a hollow interior, and including a body portion and an extension portion interconnected by a breakaway structure configured to retain structural integrity under a first predetermined tensile load and to separate under a second predetermined tensile load which is greater than the first predetermined tensile load; a collet disposed in the hollow interior, the collet having a peripheral wall defining a central bore for accepting one or more tensile members therethrough; a sleeve having a peripheral wall and being disposed in the hollow interior of the housing, so as to be movable parallel to the central axis; and wherein the sleeve and the collet are arranged such that axial movement of the sleeve will cause the collet to swage radially inwards around and against the one or more tensile members.
