Abstract
An interspinous implant. The interspinous implant includes a resilient S-shaped body having first and second saddle-shaped portions. First and second stirrup-shaped brackets extend in opposite directions from the first and second saddle-shaped portions for engaging first and second spinous processes.
Claims18
An interspinous implant comprising:
- a substantially S-shaped body having first and second ends;
- a first U-shaped extension attached to the first end, the first extension defining a first opening between a first pair of opposing legs and engageable to a first spinous process at the first opening;
- a second U-shaped extension attached to the second end, the second extension defining a second opening between a second pair of opposing legs and engageable to a second spinous process at the second opening;
- a first open saddle-shaped portion connected to the first U-shaped extension and having a first thickness;
- a second open saddle-shaped portion connected to the second U-shaped extension and having a second thickness;
- and
- an intermediate portion that is shared by the first and second saddle-shaped portions, the intermediate portion having a third thickness, the third thickness being greater than the first and second thicknesses;
- wherein the first and second open saddle-shaped portions are positioned on opposite sides of the intermediate portion in an opposing orientation along a body axis that crosses the first open saddle-shaped portion at the first thickness, the intermediate portion at the third thickness and the second open saddle-shaped portion at the second thickness and wherein the body axis is parallel to the first and second openings.

An interspinous implant comprising:
- a resilient S-shaped body including first and second open saddle-shaped portions, the first open saddle-shaped portion having a first end, the second open saddle-shaped portion having a second end;
- an intermediate portion disposed between first and second open saddle-shaped portions and that connects the first and second open saddle-shaped portions, wherein the first and second open saddle-shaped portions are oriented on opposite sides of the intermediate portion along an axis that crosses the first and second open saddle-shaped portions at least two distinct locations;
- first and second stirrup-shaped brackets extending at an angle and in opposite directions from the first and second open saddle-shaped portions, the first and second stirrup-shaped brackets having respective openings that are both parallel to the axis and that are engageable to first and second spinous processes;
- and
- first and second connecting portions, the first connecting portion disposed between the first saddle-shaped portion and the intermediate portion, the second connecting portion disposed between the second saddle-shaped portion and the intermediate portion, the intermediate portion thicker than at least one of the first and second saddle-shaped portions,
- wherein the S-shaped body is configured to move between an expanded configuration and a closed configuration, wherein in the expanded configuration a first channel is defined between the intermediate portion and the first end and a second channel is defined between the intermediate portion and the second end, wherein in the closed configuration, at least one of the first end or the second end engages the intermediate portion.

An interspinous implant comprising:
- a resilient body having a longitudinal axis and a substantially S-shape, the resilient body comprising:
- a first portion having first and second ends, the first portion being substantially U-shaped and having a first thickness;
- a second portion having first and second ends, the second portion being substantially U-shaped and having a second thickness;
- and
- an intermediate portion that is oriented between and that connects the second end of the first portion and the first end of the second portion, the intermediate portion having a third thickness that is greater than at least one of the first and second thicknesses, wherein the longitudinal axis crosses the intermediate portion at a location between the first and second portions;
- a first extension attached to the first end of the first portion, the first extension having a first pair of elongated legs that are laterally spaced and extend perpendicular to the longitudinal axis and engageable to a first spinous process;
- and
- a second extension attached to the second end of the second portion, the second extension having a second pair of elongated legs that are laterally spaced and extend perpendicular to the longitudinal axis and engageable to a second spinous process, the second extension offset relative to the first extension along the longitudinal axis.
