Abstract

An interspinous process implant for insertion between adjacent spinous processes, the implant having a flexible body having i) an upper posterior portion having an upper surface adapted to bear upon an upper spinous process, ii) a lower posterior portion having a lower surface adapted to bear upon a lower spinous process, and iii) an arcuate, flexible anterior wall connecting the upper and lower portions, wherein the anterior wall has a narrowed portion.

First claim

1 - 10 . (canceled)

11 . A method for post-operatively adjusting an implant that has been surgically implanted proximate to a patient's spinal cord, the implant including a sensor capable of determining a change in the physical surroundings of the implant, comprising:
post-operatively analyzing by the sensor of the physical surroundings of the implant; post-operatively determining by the sensor of a significant change in the physical surroundings of the implant; and post-operatively adjusting a characteristic of the implant in response to the determined significant change in the physical surroundings of the implant.

12 . The method of claim 11 , wherein adjusting a characteristic of the implant includes providing an electric stimulus.

13 . The method of claim 11 , wherein the sensor is contained within the implant.

14 . The method of claim 11 , further comprising the step of reporting data analyzed by the sensor to an ex vivo source.

15 . The method of claim 14 , wherein the step of reporting is performed by a reporter contained within the implant.

16 . The method of claim 11 , wherein adjusting a characteristic of the implant results in an alleviation of the patient's pain.

17 . The method of claim 11 , further comprising the step of implanting the implant proximate to the patient's spinal cord so as to alleviate pain.

18 . The method of claim 11 , wherein analyzing the physical surroundings of the implant includes analyzing the patient's motion.

19 . The method of claim 11 , wherein the implant is a spinal implant.

20 . A method for post-operatively adjusting an implant that has been surgically implanted proximate to a patient's spinal cord, the implant including a sensor capable of determining a change in the physical surroundings of the implant, comprising:
post-operatively analyzing by the sensor of the physical surroundings of the implant; post-operatively determining by the sensor of a significant change in the physical surroundings of the implant; and post-operatively providing an electric stimulus in response to the significant change in the physical surroundings of the implant.

21 . The method of claim 20 , wherein the implant is a spinal implant.

22 . The method of claim 20 , wherein analyzing the physical surroundings of the implant includes analyzing the patient's motion.

23 . The method of claim 20 , wherein providing an electric stimulus results in an alleviation of the patient's pain.

24 . The method of claim 20 , further comprising the step of implanting the implant proximate to the patient's spinal cord so as to alleviate pain.

25 . The method of claim 11 , wherein the sensor is contained within the implant.

26 . The method of claim 11 , further comprising the step of reporting data analyzed by the sensor to an ex vivo source.

27 . The method of claim 26 , wherein the step of reporting is performed by a reporter contained within the implant.
