Abstract

An apparatus for treating pain by electrical stimulation is disclosed. A lead is placed subcutaneously in the region of pain. The subcutaneous tissue is electrically stimulated to cause paresthesia. The method encompasses subcutaneous placement of an electrical lead near the region of pain and subsequent electrical stimulation of the tissue to cause paresthesia. In particular, an apparatus for treating intractable lower back pain using percutaneous electrostimulation techniques is disclosed.

Claims

1-34. -34. (canceled)

35. A method of treating lower back pain comprising:

(a) palpating the lower back of a patient to identify a painful area,

(b) percutaneously placing at least one electrode in subcutaneous tissue proximate to said area of pain;

(c) applying electrical stimulating pulses from an implantable tissue stimulator to said electrode of a frequency, amplitude and duration sufficient to induce paresthesia; and

(d) surgically implanting the tissue stimulator beneath the skin.

36. The method of claim 35 wherein the implantable tissue stimulator comprises an implantable pulse generator.

37. The method of claim 35 wherein the implantable tissue stimulator comprises a radio frequency system receiver.

38. The method of claim 35 wherein the at least one electrode is on a test lead and further including before step (d) replacing the test lead with a permanent lead that includes a stimulating electrode thereon.

39. The method of claim 35 wherein the at least one electrode is also entirely superficial to the muscle fascia in said area.

40. A method of treating lower back pain comprising the steps of

(a) palpating the lower back of a patient to identify a painful area subserved by a peripheral nerve proximate to said area of pain;

(b) percutaneously placing at least one electrode in subcutaneous tissue at a location entirely superficial to the nerve identified in step (a);

(c) applying electrical stimulating pulses from an implantable tissue stimulator to said electrode of a frequency, amplitude and duration sufficient to induce paresthesia without an attendant burning or grabbing sensation; and

(d) surgically implanting the tissue stimulator beneath the skin.

41. The method of claim 40 wherein the implantable tissue stimulator comprises an implantable pulse generator.

42. The method of claim 40 wherein the implantable tissue stimulator comprises a radio frequency system receiver.

43. The method of claim 40 wherein the at least one electrode is on a test lead and further including before step (d) replacing the test lead with a permanent lead that includes a stimulating electrode thereon.

44. The method of claim 40 wherein the at least one electrode is also entirely superficial to the muscle fascia in said area.
