Abstract
A medical lead anchor anchors a medical lead relative to the epidural space of the spinal cord, intrathecal space, or peripheral nerve of a patient. The lead anchor comprises a sleeve having a plurality of eyelets and a passage through the sleeve. The anchor further comprises a locking device defining a collet, a collet driver and a handle. The locking device has a lead passage. The collet driver is sized to fit the passage in the sleeve and has a spiral slot to operatively engage a pin on the sleeve located in the sleeve passage. The sleeve and attached locking device are slid over the lead. The sleeve is sutured to tissue located near the location where the lead enters the epidural space. The collet and collet driver of the locking device are moved along the passage of the sleeve with the spiral slot of the collet driver operatively engaging the pin. The handle of the locking device is turned, moving the collet and collet drive as described, to advance the collet through the passage in the sleeve, thereby pinching the collet to a pre-determined tightness on the lead and thus releasably securing the lead in the desired position.
