Tension clamp side loading lead anchor and methods and systems using the lead anchor

摘要

An implantable lead anchor includes a first anchor shell having a first hinge element and a second anchor shell, disposed opposite the first anchor shell, having a second hinge element. The first and second anchor shells define a lead channel and the first and second hinge elements form a hinge. The lead anchor includes at least one tensioning element that is configured and arranged to increase in tension upon elongation. The first and second anchor shells, and the tensioning element provide an open position and a closed position. In the open position, a lead can be side loaded side loaded into the lead channel. In the closed position, the first and second anchor shells grip a portion of the lead disposed in the lead channel and, in combination with the at least one tensioning element, resist disengagement of the lead from the lead anchor.

主权项

1. An implantable lead anchor, comprising:
a first anchor shell comprising a first hinge element; a second anchor shell disposed opposite the first anchor shell and comprising a second hinge element, the first and second anchor shells defining a lead channel between the first and second anchor shells and the first and second hinge elements forming a hinge; and at least one tensioning element coupled to the first and second anchor shells, wherein each of the at least one tensioning element is configured and arranged to increase in tension upon elongation; wherein the first and second anchor shells and the at least one tensioning element are configured and arranged to provide an open position and a closed position, wherein, in the open position, a lead can be side loaded into the lead channel and, in the closed position, the first and second anchor shells grip a portion of the lead disposed in the lead channel and, in combination with the at least one tensioning element, resist disengagement of the lead from the lead anchor, wherein the lead anchor is configured and arranged to move between the open position and the closed position using the hinge and the lead anchor further defines an intermediate position between the open position and the closed position in which, in the intermediate position, the at least one tensioning element is more elongated than in both the open position and the closed position.
