## Abstract

An interspinous fusion device is described. It includes a first member with a column of teeth, and a second member with a column of recesses adapted to mate with the column of teeth of the first member. The first member and the second member have opposing windows on their walls, such that when the first member is mated with the second member an unobstructed passage is formed through the opposing windows. The first member and the second member lock together when the teeth and recesses are mated, said locking occurring without the aid of a set screw, pin or other mechanical component.

## Claims

### Claim 1

An interspinous fusion device comprising:
a first member comprising a column of teeth;
a second member comprising a column of recesses adapted to mate with the column of teeth of the first member, said first member and said second member having opposing windows on their walls, such that when the first member is mated with the second member an unobstructed passage is formed through the opposing windows, and wherein the first member and the second member lock together when the teeth and recesses are mated, said locking occurring without the aid of a set screw, pin or other mechanical component.
