Patent classifications
A61B17/7258
Bone plate
A bone plate that includes apertures for bone screws and locking screws is disclosed. The locking screws can be in an aperture adjacent to the locking screw aperture such that when the locking bone screws and locking screws are in place, the head of the locking screw at least partially covers the head of the bone screw. In another example, the locking screw aperture is threaded, and the locking screw is placed on top of the bone screw.

STENT
A stent is disclosed that has an elongated body composed of a bioabsorbable polymer having a proximal end, a distal end, two open spiral channels formed on the exterior surface of the body to provide fluid communication between the proximal end and the distal end. The stent also has a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire. A method for using the stent and a kit containing the stent are also disclosed.
Arthrodesis implant
A resorbable implant for osteosynthesis for stiffening in a central joint (e.g., the proximal interphalangeal joint referred to as PIP) during arthrodesis or for stiffening in an end joint (e.g., the distal interphalangeal joint referred to as DIP) during arthrodesis and for osteosynthesis and stabilization of fractures of small bones of the human skeleton includes two shafts placed against each other. At least one fixing aid is located between the shafts. The fixing aid protrudes beyond a diameter of the shafts. Each shaft may have longitudinal grooves and transverse grooves. The implant is a magnesium-based material which can be resorbed by the human body. The disclosed implant has a relatively high tensile strength, excellent stability, optimal healing properties, and an optimally adapted resorption speed.
APPARATUS AND METHODS FOR FRACTURE REPAIR
Apparatus and methods for bone fracture repair. The apparatus may include a structural support for positioning a first bone segment relative to a second bone segment. The apparatus may include an anchoring substrate. The anchoring substrate may be configured to compress the first bone segment to the second bone segment. The anchoring substrate may transmit tension from a distal bone segment anchor in the first bone segment to a proximal bone segment anchor in the second bone segment. The apparatus may be configured to be deployed percutaneously in an inner cavity of a bone. The apparatus may be installed in an open fracture. The apparatus may be expanded, self-expanding or configured for mechanically actuation. Some embodiments of the apparatus may include a central axis member that may be used in conjunction with expansion of one or both of the structural support and the anchoring substrate to configure the apparatus.
Expandable bone nail
An intramedullary nail is suggested comprising a nail shaft with a lateral recess, with an expansion element being arranged in that recess, and an adjustment screw for adjusting the position and orientation of the expansion element relative to the nail shaft. A threaded bore may be formed in the nail shaft, wherein the threaded bore extends through the nail shaft and into the recess and is adapted to receive the adjustment screw.
Expandalbe intramedullary systems and methods of using the same
Intramedullary systems, expandable intramedullary nails, expandable anchors, and methods of using the same. The intramedullary system may include an expandable intramedullary nail configured to extend into an intramedullary canal of a long bone and/or one or more expandable anchors configured to extend at an angle transverse to the intramedullary nail. The intramedullary nails and/or anchors may include one or more integrated expansion mechanisms that allow for insertion in a contracted configuration and expansion into a deployed configuration to lock the relative position and prevent axial rotation and translation of the system.
SYSTEMS AND METHODS FOR INSTALLING ANKLE REPLACEMENT PROSTHESES
An ankle implant for use in ankle arthroplasty in total ankle replacement is provided. The implant includes an upper prosthesis anchored to the tibia and a lower prosthesis anchored to the talus. The lower prosthesis is operable associated with the upper prosthesis. The implant also includes a stem which is rigidly removably connected to the second member. The stem includes a portion for attachment to the calcaneous. The stem is be adapted to be in a first position in the calcaneous when the stem is in a first relative position with respect to the lower prosthesis, and to provide for a second position in the calcaneous when the stem is in a second relative position with respect to the lower prosthesis.
Locking System For Femoral Neck Fracture Fixation
A fixation device for providing rotation stability to a femoral neck fracture. The device includes a bone plate having at least one opening, a compression screw housing extendable through the opening of the bone plate, a compression screw being at least partially disposed within the bore of the housing and selectively moveable through the bore, and a collapsible and expandable anchoring member coupled to the compression screw. The anchoring member is configured to transition between a collapsed condition and an expanded condition upon advancement of the anchoring member from the compression screw housing to rotationally stabilize the compression screw within a femur.
Stent
A stent is disclosed that has an elongated body composed of a bioabsorbable polymer having a proximal end, a distal end, two open spiral channels formed on the exterior surface of the body to provide fluid communication between the proximal end and the distal end. The stent also has a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire. A method for using the stent and a kit containing the stent are also disclosed.
