ABSTRACT:
An implantable lead fixation apparatus, including two suture collars connected by a flexible retaining member of predetermined length, is provided for anchoring an elongate cylindrical electrode lead to a patient's body. Each suture collar comprises a flexible annular member having a central lumen that is adapted to enclose the lead. The suture collars each include provision for securing the lead against longitudinal movement of the lead with respect to the collar, and provision for anchoring the collar to the patient's body. The suture collars are positioned relatively proximally and distally with respect to the lead, and are secured on the lead with the proximal suture collar being separated from the distal suture collar by slightly less than the length of the retaining member. Then, the lead fixation apparatus is positioned with respect to the patient's body and secured to the body so that the proximal suture collar is located at a selected distance less than the predetermined distance from, and at an angular orientation to, the distal suture collar to provide slack in both the lead and the retaining member in order to accommodate patient movement without applying dislocating forces to a distal portion of the lead.
