Abstract
An interspinous distraction kit is provided with a distal anchor comprising a locking section moveable from a radially un-extended position in a non-deployed configuration to a radially extended position in a deployed configuration. A method for maintaining a space between adjacent spinous processes by unilateral access to the spinous processes is also provided.
Claims25
An interspinous distraction kit comprising:
- a distal anchor comprising a first member pivotally coupled to a second member, the first member moveable from a radially un-extended position in a non-deployed configuration to a radially extended position in a deployed configuration;
- and
- a spacer having an inner surface defining an opening therethrough, the spacer configured to maintain a space between adjacent spinous processes.
An interspinous distraction kit comprising:
- a distal anchor comprising a first locking section moveable from a radially un-extended position in a non-deployed configuration to a radially extended position in a deployed configuration;
- and
- a spacer having an inner surface defining an opening therethrough, the spacer configured to be maintain a space between adjacent spinous processes.
An interspinous distraction kit comprising:
- a distal anchor comprises a tubular member axially splitting into at least two limbs;
- a wedge;
- and
- a spacer configured to maintain a space between adjacent spinous processes.

An interspinous distraction assembly comprising:
- a tubular member axially splitting into at least a pair of proximal limbs and at least a pair of distal limbs, the tubular member defining a bore extending therethrough;
- a proximal wedge defining an opening therethrough;
- a distal wedge;
- and
- a spacer positioned on the tubular member between the proximal limbs and the distal limbs.

A method for maintaining a space between adjacent spinous processes comprising:
- incising a lateral portion of the patient's body;
- advancing an interspinous assembly towards the midline of the patient's body, the interspinous assembly comprising a spacer, a distal anchor, and a proximal anchor;
- positioning the spacer in the interspinous space between adjacent spinous processes;
- deploying the distal anchor to secure the distal anchor against the distal surface of the adjacent spinous processes;
- and
- deploying the proximal anchor after deployment of the distal anchor to secure the proximal anchor against the proximal surface of the adjacent spinous processes.
