Abstract
An interspinous spacer that includes a body having a distal portion and a proximal portion; an actuator at least partially disposed in the body; and a first arm and a second arm, where the first and second arms are rotatably coupled to a distal portion of the body and coupled to the actuator, where the actuator, first arm, and second arm are configured, upon rotation of the actuator in a first direction, to move the first and second arms from an implantation position, in which the first and second arms extend from the distal portion of the body back toward the proximal portion of the body, to a deployed position, in which the first and second arms extend away from the body.
Claims18
An interspinous spacer, comprising:
- a body having a first pair of opposing, lateral, external sides, a second pair of opposing, lateral, external sides different from the first pair, a distal portion, and a proximal portion, wherein the body defines an opening on each side of the first pair of opposing, lateral, external sides;
- an actuator at least partially disposed in the body;
- a first arm and a second arm, wherein each of the first arm and the second arm comprises two extensions, a bridge coupling the two extensions together, and an attachment portion extending from the bridge, through the opening of a one of the sides of the first pair of opposing, lateral, external sides, toward the actuator, wherein the attachment portion is rotatably coupled to the body and engages the actuator, wherein the actuator, first arm, and second arm are configured, upon rotation of the actuator in a first direction, to rotate the first and second arms from an implantation position, in which the two extensions of each of the first arm and the second arm are external to a remainder of the interspinous spacer with a portion of each sides of the second pair of opposing, external, lateral sides of the body between the two extensions along a majority of a length of the two extensions, to a deployed position, in which the first and second arms extend away from the body;
- a first pin rotatably coupling the first arm to the body;
- and
- a second pin rotatably coupling the second arm to the body.
