Intramedullary nails
The present invention is generally directed to intramedullary nails that can include a keel configured for rotational stabilization and/or a multi-sectioned rod configured to apply compression to a fracture.
Hammer toe implant with expansion portion for retrograde approach
A system includes and implant and an elongate device. The implant includes a first bone engaging portion and a flexible portion coupled to an end of the first bone engaging portion at an engagement portion. The flexible portion is configured to be compressed toward a longitudinal axis defined by the flexible portion. The elongate device includes an engagement end that is sized and configured to engage the engagement portion of the implant.
Humeral Head Fixation Device for Osteoporotic Bone
A device includes an elongated body configured to be coupled to a bone stabilization implant so that, when the bone stabilization implant is mounted to a target bone, the body extends away from the bone stabilization implant at an angle selected so that the elongated body passes into a target portion of bone. The body defines a lumen therein extending to an opening in a distal end of the body. The device also includes a deploying member housed within the lumen of body for movement between a first position and a second position. In addition, the device includes a plurality of wires coupled to the deploying member so that movement of the deploying member through the lumen moves the wires between an insertion position and a deployed position in which the distal ends of the wires penetrate a portion of bone adjacent to the distal end of the body.
SUPER-ELASTIC IMPLANT SYSTEM
A super-elastic implant system and method can include: a rigid mandrel; and an implant including a main body in the shape of a tube, the main body formed of a shape set material configured to have: a stress induced martensitic phase in a deformed shape having a straight end, the deformed shape based on the main body being constrained on the mandrel, and an austenitic phase having a non-linear curve, the non-linear curve in the location of the straight end, and the austenitic phase based on the main body being removed from the mandrel.
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.
A SURGICAL IMPLANT FOR FUSION BETWEEN TWO BONE PORTIONS AND A CLAMPING ANCILLARY FOR CLAMPING SUCH A SURGICAL IMPLANT
A surgical implant which includes: a first anchoring portion comprising two first arms movable between an inserting position and an anchoring position, in which the first arms are spread apart so as to be anchored in a first bone; a second anchoring portion to be anchored in the second bone; and an intermediate portion connecting the first anchoring portion to the second anchoring portion. The intermediate portion comprises: a recess; and a first connecting portion and a second connecting portion that are remote from one another. Bringing the first connecting portion and second connecting portion closer together moves the first arms from the inserting position thereof to the anchoring position thereof.
METHOD AND APPPARATUS FOR AN INTRAMEDULLARY IMPLANT AND METHOD OF IMPLANTATION THEREFOR
An intramedullary orthopedic implant includes a body section having a first end that provides a point of insertion for the body section and a second end. The body section further includes wings extending away from the point of insertion for the body section. The intramedullary orthopedic implant further includes first and second legs extending from the second end of the body section. The first and second legs begin in a first implanted shape, are movable to a second insertion shape, and remain in the second insertion shape as long as the first and second legs are mechanically constrained.
Stent
A bioabsorable stent is disclosed. The stent is made of a polymer and/or non-polymer material and has an elongated body having a proximate end, a distal end, and at least one open channel formed on the exterior surface of the elongated body to provide fluid communication between the proximal end and the distal end. Also disclosed is a bioabsorable stent having an elongated center rod having a proximate end and a distal end and a plurality of leaflets extending outward from the center rod and forming channels between two neighboring leaflets to provide fluid communication between the proximal end and the distal end.
INTRAMEDULLARY ANCHOR-SCREW FRACTURE FIXATION
The present invention relates to an improved intramedullary fracture fixation device, the device including a first fastener comprising a head and an at least partially threaded shaft extending from the head, a tiltable load spreading element adapted to couple to the first fastener and having a bone-contacting surface defining bone engagement features and a head-contacting surface, and a second fastener having external threads and a central bore for receiving the threaded shaft of the first fastener. The central bore defines an inner wall surface which is at least partially threaded, the inner wall surface being configured for mating engagement on the outer surface of the shaft of the first fastener such that rotation of the first fastener relative to the second fastener causes the translation of the first fastener relative to the second fastener along the shaft. The load spreading element is configured and dimensioned to interact operatively with at least a surface of the bone and at least a surface of the head to spread the load exerted by the head on the bone over a large bone surface area and, optionally, to prevent the head from completely passing through the bone. The present invention permits a minimally invasive repair of bone fractures that may otherwise be treated through larger incisions. The present invention also relates to the method of fixation of the device.
INTRAMEDULLARY IMPLANT, SYSTEM, AND METHOD FOR INSERTING AN IMPLANT INTO A BONE
An intramedullary implant system, and method for placement within a bone system are provided by the invention. The implant includes a body with at least one pair of beams arranged about a longitudinal axis of the body. The beams are each fixed to the body and each have an end. The end of one of the beams of a pair is releasably coupled to the other beam of the pair by a k-wire from one end of which extends a flexible tail. The beams are each deflectable between (i) a coupled and biased position for insertion of the beams into a respective bone, and (ii) an uncoupled position for gripping bone. The beams of each pair in the uncoupled position being arranged so as to compressively engage the bone.
