A percutaneous interspinous process device for treating spinal conditions
includes a first section, a second section, and a locking mechanism. The
first section defines a first lateral surface, a first medial surface and
a first lumen extending from the first lateral surface to the first
medial surface. The second section defines a second lateral surface, a
second medial surface and a second lumen extending from the second
lateral surface. The locking mechanism includes an elongate member
protruding from the first medial surface of the first section and a
medial recess defined in the second medial surface of the second section.
The medial recess is configured for securely receiving at least a portion
of the elongate member. The elongate member is configured to define a
space between adjacent spinous processes and maintain a predetermined
distance between adjacent spinous processes.
