Strain Relief System For Spinal Cord Stimulation Lead
First Claim
1. An apparatus for anchoring a neurostimulation lead in a patient, comprising:
- a tubular housing having a first portion for anchoring the housing proximately to the spinus process of the patient and a second portion extending from the first portion for providing strain relief; and
wherein said second portion is configured to extend at least partially into the ligamentum flavum of the patient when said first portion is attached to the patient.

Abstract
An anchor for spinal electrical stimulation leads having a first, extended portion adapted to be inserted through the spine and into the spinal column, and a second, shorter portion adapted to be sutured to the fascia on the outside of the spine. The extended portion assists with positioning of the electrode tip onto the spinal cord on provides strain relief for the electrode. The anchor further comprises an inner tube disposed inside of the housing along an intermediate portion between the extended portion and the shorted portion. When the outside portion of the tubular housing is sutured to the fascia of a patient, the inner tube is compressed against the electrical lead, thereby locking it in place and preventing migration over time.
