US 2016/0250034 A1 · Adjustable implant

Abstract

An adjustable implant (10, 60, 70, 80, 90) has a base (12) and a displaceable element (16) providing opposing tissue contact surfaces (14, 18). A linkage (20, 26) is pivotally connected to the displaceable element. A linkage mover (38, 40), engaged so as to be displaceable along the base, is associated with the linkage (20, 26) so as to define a displaceable pivot location (24, 30) for pivotal motion of the linkage relative to the base, in certain preferred embodiments, the base (12) has an internally threaded track (42, 44) in which a threaded segment of the linkage mover (38, 40) 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.

Dependent claims

An adjustable implant for deployment between a first and a second tissue surface, the implant comprising:

(a) a base having a length, said base providing a first contact surface for deployment against the first tissue surface;
(b) a displaceable element providing a second contact surface for deployment against the second tissue surface;
(c) a linkage pivotally connected to said displaceable element;
and
(d) a linkage mover engaged with said base so as to be displaceable along at least part of said length of said base, said linkage mover being associated with said linkage so as to define a displaceable pivot location for pivotal, motion of said linkage relative to said base,
wherein said base comprises an internally threaded track, and wherein said linkage mover comprises a threaded segment engaged with said internally threaded track such that rotation of said threaded segment about a central axis of said threaded segment advances said linkage mover along said threaded track, thereby displacing said displaceable pivot location such that said linkage adjusts a separation between said first contact surface and at least part of said second contact surface.

An adjustable implant for deployment between a first and a second tissue surface, the implant comprising:

(a) a base having a length, said base providing a first contact surface for deployment against the first tissue surface;
(b) a displaceable element providing a second contact surface for deployment against the second tissue surface;
(c) a first linkage pivotally connected to said displaceable element and pivotally associated with said base at a first displaceable pivot location;
(d) a second linkage pivotally connected to said displaceable element and pivotally associated with said base at a second displaceable pivot location;
and
(e) an actuation arrangement associated with said base and operable to act on said first and second linkages so as to move said displaceable pivot locations, thereby adjusting a spacing and/or angle between said first and second contact surfaces, said actuation arrangement being selectively operable to adjust said first displaceable pivot location without moving said second displaceable pivot location.
