Abstract
Abstract A method of managing chronic pain produced by a variety of disorders or conditions which afflict the pelvic region and which is transmitted through the lumbosacral region of the human body. The method includes techniques for positioning one or more stimulation leads within or about the sacrum to enable electrical energy to be applied to spinal nervous tissue, including nerve roots, to inhibit the transmission of pain.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
110 words
A method of managing chronic pelvic pain using a signal generator and at least one stimulation lead having an electrode portion and a connector portion, where the connector portion is electrically connectable to the signal generator, the method comprising the steps of: surgically implanting the at least one stimulation lead so that the electrode portion of the at least one stimulation lead lies in a plane substantially parallel to selected sacral nerve roots within the epidural space of a sacrum; coupling the at least one stimulation lead to the signal generator; and delivering electrical energy from the signal generator to the electrode portion of the at least one stimulation lead.
Claim 2
Independent Claim
110 words
A method of managing chronic pelvic pain using a signal generator and at least one stimulation lead having an electrode portion and a connector portion, where the connector portion is electrically connectable to the signal generator, the method comprising the steps of: surgically implanting the at least one stimulation lead so that the electrode portion of the at least one stimulation lead lies in a plane substantially parallel to selected sacral nerve roots within the epidural space of a sacrum; coupling the at least one stimulation lead to the signal generator; and delivering electrical energy from the signal generator to the electrode portion of the at least one stimulation lead.
Claim 3
Dependent Claim
23 words
A method in accordance with claim 1, wherein a plurality of stimulation leads are implanted and coupled to at least one signal generator.
Claim 4
Dependent Claim
21 words
A method in accordance with claim 1, wherein the electrical energy has a signal frequency within the range of 50-3,000 Hz.
Claim 5
Dependent Claim
41 words
A method in accordance with claim 1, wherein the electrode portion of the at least one stimulation lead additionally extends along one or more of the following portions of the sacral nerve roots: dorsal root ganglia, sacral plexus, and peripheral nerve.
Claim 6
Dependent Claim
23 words
A method in accordance with claim 1, wherein the electrode portion of the at least one stimulation lead extends through a sacral foramen.
Claim 7
Dependent Claim
60 words
A method in accordance with claim 1, wherein the at least one stimulation lead is inserted at a vertebral position superior to S1/S2 and advanced within the epidural space in an inferior direction prior to a final position, wherein an intermediate portion of the at least one stimulation lead is substantially parallel to a longitudinal axis of the epidural space.
Claim 8
Dependent Claim
38 words
A method in accordance with claim 1, wherein the at least one stimulation lead is inserted through a sacral hiatus and advanced within the epidural space of the sacrum in a superior direction prior to a final position.
