Anchor apparatus
An anchor for anchoring tensile members to bone includes: a housing extending along a central axis, with a hollow interior; a collet in the hollow interior having a central bore for accepting tensile members and an exterior surface, the collet being configured to swage around and against tensile members; a sleeve having a peripheral wall defining interior and exterior surfaces, the sleeve disposed in the housing's hollow interior axially adjacent to the collet, and movable parallel to the central axis between first and second positions; and wherein at least one of the collet exterior surface and the sleeve interior surface is tapered and the sleeve and the collet are arranged so movement of the sleeve from the first position to the second position causes the sleeve interior surface to bear against the collet exterior surface, causing the collet to swage radially inwards around and against one or more tensile members.
Joint repair system
A joint stabilization (reduction) system and associated methods and tools for placement of the system in an open or minimally invasive technique. The joint stabilization system includes a flexible prosthetic band for stabilizing the bones in proper position and a connector mechanism for joining the two ends of the prosthetic band around the bones. One end of the prosthetic band can be permanently attached to the connector.
Method and apparatus for directing an elongate flexible component through a part of a human body
A method of, and apparatus for, directing an elongate flexible component with a length through a part of a human body. The method includes the steps of: obtaining an apparatus having an elongate body with a length between axially spaced leading and trailing ends and a notch through a peripheral surface of the elongate body; directing a midlength part of the elongate flexible component into the notch to place the elongate flexible component into an operative position on the apparatus; and with the elongate flexible component in the operative position, advancing the elongate body through the part of the human body and thereby causing a portion of the elongate flexible component to be drawn by a drawing surface on the elongate body through the part of the human body.

Load distributor for a sternum closure device and tool for cutting the load distributor
A load distributor for a sternum closure device comprises a wire receiving section configured to be attached to a wire of the sternum closure device, and a load distributing section. A tool for cutting the load distributor comprises a pair of jaws movable between a load distributor receiving position and a cutting position, wherein at least one of the jaws has substantially V-shaped cutting edges tapered towards the other jaw in an angle to the longitudinal extension of the tool.
Tensioner for a sternal closure strap device
A handheld closing device for closing a bone closure device. The handheld closing device includes a main body portion with an end and a receiving member located at the end of the main body portion. The receiving member is configured for receiving the securing member of the bone closure device. The handheld closing device further includes a tightening member rotatably connected to the main body portion. The tightening member includes a receiving hole configured for receiving the strap of the bone closure device. The tightening member is configured for tightening the strap. The handheld closing device further includes a lever pivotally connected to the main body portion. The lever is configured for operably engaging with the securing member to position the securing member in its locked position.
Reversible pin driver
An implant driver for engaging an orthopedic implant for selective advancement and retraction of the implant. The implant driver includes a first jaw assembly comprising a helical cam surface corresponding with a first direction of rotation. The first jaw assembly is operative to engage, in response to rotation in the first direction, the implant using spherical jaw members disposed in constrictive helical channels. The implant driver includes a second jaw assembly comprising a helical cam surface corresponding with a second direction of rotation. The second jaw assembly is operative to engage, in response to rotation in the second direction, the implant using spherical jaw members disposed in constrictive helical channels. Absent rotation of the first and second jaw assemblies, the spherical jaws may not restrict relative axial movement between the implant and the implant driver to allow for advancement and/or retraction of the instrument relative to the implant.
SURGICAL INSTRUMENT CONNECTORS AND RELATED METHODS
Connectors for connecting or linking one instrument or object to one or more other instruments or objects are disclosed herein. In some embodiments, a connector can include a first arm with a first attachment feature for attaching to a first object, such as a surgical access device, and a second arm with a second attachment feature for attaching to a second object, such as a support. The connector can have an unlocked state, in which the position and orientation of the access device can be adjusted relative to the support, and a locked state in which movement of the access device relative to the support is prevented or limited. Locking the connector can also be effective to clamp or otherwise attach the connector to the access device and the support, or said attachment can be independent of the locking of the connector.
Universal wire driver
A universal wire driver attachment comprises a driveshaft forming a lumen extending along a longitudinal axis. The driveshaft forms a plurality of channels extending perpendicularly from the longitudinal axis. The attachment further comprises a plurality of primary jaws movably disposed at least partially within the channels. The primary jaws comprise a plurality of wire gripping surfaces facing the longitudinal axis and configured to grip the surgical wire. The primary jaws cooperate with the channels such that the primary jaws are constrained from moving in an axial direction along the longitudinal axis. The primary jaws are capable of moving outward from the longitudinal axis when the surgical wire is inserted between the primary jaws, and the primary jaws are capable of being urged inward toward the longitudinal axis by the securing mechanism to increase a grip force on the surgical wire.
Transosseous guide and method
Instruments and methods for surgical transosseous attachment to a bone include a guide able to guide the formation of intersecting bone tunnels and a passer able to pass a member through the bone tunnels.
