Abstract
Interspinous process implants are disclosed. Also disclosed are systems and kits including such implants, methods of inserting such implants, and methods of alleviating pain or discomfort associated with the spinal column.
Claims17
A method of implanting a device between adjacent spinous processes comprising:
- creating an incision in a patient to be treated;
- dilating any interspinous ligaments in a position in which the device is to be placed in the patient;
- sizing a space between adjacent spinous processes;
- and
- inserting the device between the adjacent spinous processes in a first position, the device comprising:
- an elongate body comprising a first end portion, a second end portion, and a central support portion disposed between the first end portion and the second end portion;
- wherein the first end portion comprises a wing member movable from the first position to a second position, the wing member including an outer surface and an inner surface that faces a central longitudinal axis of the elongate body;
- wherein in the first position, the wing member serves as a ramp to engage and separate the adjacent spinous processes;
- and
- moving the device to the second position to expand the wing member such that a portion of the inner surface of the wing member is capable of contacting a lateral surface of at least one of the spinous processes to limit movement of the device with respect thereto.

- dilating any interspinous ligaments in a position in which the device is to be placed in the patient;
- sizing a space between adjacent spinous processes;
- and
- inserting the device between the adjacent spinous processes in a first position, the device comprising:
- a body comprising a support portion extending laterally along a lateral axis between first and second end portions;
- wherein at least a portion of the first end portion is moveable from the first position to a second position, the first end portion includes an outer surface and an inner surface that faces a central longitudinal axis of the body;
- wherein when in the first position, the first end portion comprises a ramp on at least a portion of the outer surface configured and dimensioned to engage and separate the adjacent spinous processes when inserted, and a sidewall of the first end portion faces the lateral axis of the body;
- and
- moving the device to the second position such that the portion of the first end portion that is moveable extends beyond the support portion in a direction perpendicular to the lateral axis to a greater extent than in the first position, and the sidewall of the first end portion faces the second end portion, wherein the sidewall is configured and dimensioned to engage a lateral surface of at least one of the adjacent spinous processes to limit lateral movement with respect thereto.
