An implant () includes a base (), and a sequence of at least two segments including a first segment () and a last segment (). The first segment () is pivotally linked to base (). Adjacent segments are interconnected at pivotal connections (). A bolt () has a threaded shaft () and a head (). The threaded shaft () is engaged in a threaded channel () of the base () so that rotation of the bolt () about a central axis of the threaded shaft () varies a degree of overlap between the base () and the bolt (). The last segment () and the head () define therebetween a spherical bearing (). Rotation of bolt () thus varies a distance between spherical hearing () and hinge pin (), thereby causing deflection of the sequence of segments.

Expandable implant with deflectable sequence of segments

An adjustable implant includes a telescopic body with first and second portions in sliding engagement, and a deflectable linkage formed from a first linking segment, an intermediate segment and a second linking segment pivotally interconnected so that adjustment of a length of the telescopic body causes a corresponding deflection of the deflectable linkage. The first linking segment and the second linking segment are formed with projecting features that provide a partial gear engagement between the first and second linking segments such that, during adjustment of a length of the telescopic body and corresponding deflection of the deflectable linkage, pivotal motion of the first and second linking segments relative to the intermediate segment about the first and second pivot axes occurs in a fixed ratio defined by the partial gear engagement.

Adjustable implant

An expandable implant () has a base () and a displaceable element () hingedly interconnected at one end. At the other end, the base and the displaceable element are formed with complementary jaws () which provide continuous overlap of facing surfaces over a range of angular positions of the displaceable element relative to said base. In some cases, the first end portion () of the displaceable element () is formed with projecting teeth () forming a partial gear centered on an axis () of the hinged interconnection with the base () for engaging a worm gear. In certain embodiments, the base is formed with a socket () for removably receiving a worm gear tool () for engaging the teeth () and displacing said displaceable element. After expansion, the worm-gear tool () can be removed.

Expandable implant

A device () which serves as a stiff guide wire for surgical procedures includes a tube () having an internal channel, and a central rod () in close-fitting sliding engagement within the tube. The tips of the tube and the central rod are in rigid mechanical engagement or interconnection. A region of the tube () is longitudinally slotted to form deflectable strips () so that advancing of the tube () relative to central the rod () causes outward deflection of the strips () to form an anchoring configuration. The central rod () and the tube () together define a stiff guide wire preferably having a length-to-width ratio in excess of 100:1.

Stiff guide wire with anchoring configuration

An implant () includes a base (), and a sequence of at least two segments including a first segment () and a last segment (). The first segment () is pivotally linked to base (). Adjacent segments are interconnected at pivotal connections (). A bolt () has a threaded shaft () and a head (). The threaded shaft () is engaged in a threaded channel () of the base () so that rotation of the bolt () about a central axis of the threaded shaft () varies a degree of overlap between the base () and the bolt (). The last segment () and the head () define therebetween a spherical bearing (). Rotation of bolt () thus varies a distance between spherical bearing () and hinge pin (), thereby causing deflection of the sequence of segments.

An adjustable implant () has a base () and a displaceable element () providing opposing tissue contact surfaces (). A linkage () is pivotally connected to the displaceable element. A linkage mover (), engaged so as to be displaceable along the base, is associated with the linkage () so as to define a displaceable pivot location () for pivotal motion of the linkage relative to the base, in certain preferred embodiments, the base () has an internally threaded track () in which a threaded segment of the linkage mover () is engaged, so that rotation of the threaded segment about its central axis advances the linkage mover along the threaded track, thereby displacing the displaceable pivot locations and adjusting a separation between the first contact surface and at least part of the second contact surface.
