LEAD ANCHORS AND SYSTEMS AND METHODS USING THE LEAD ANCHORS

摘要

A lead anchor includes a body defining a lead lumen extending from a first end to a second end of the body to receive a lead, and a transverse lumen extending from a top end of the body and perpendicularly intersecting the lead lumen. Further, anchor includes a fastener disposed in the transverse lumen and configured for fastening the lead to the anchor by engaging a portion of the lead. The fastener includes a head defining an indented pattern configured to receive a tip portion of a tool. The pattern is tilted so that the tip portion of the tool can be inserted into the pattern at an angle with respect to the transverse lumen. The angle lies between 20-85 degrees as measured between a tool's longitudinal axis and a plane that contains the lead lumen's longitudinal axis and is perpendicular to the transverse lumen.

主权项

1. A lead anchor, comprising:
a body having an outer surface, a top end, a from side, a first end, and a second end opposite to the first end, the body defining:
a longitudinal lead lumen extending from the first end of the body to the second end of the body said configured and arranged to receive a lead, anda transverse lumen extending from the top end of the body and perpendicularly intersecting the lead lumen; and a fastener disposed in the transverse lumen and configured and arranged for fastening the received lead to the lead anchor by engaging a portion of the lead, the fastener comprising a head that defines an indented pattern that is configured and arranged to receive a tip portion of a tool so that the tool can be used to rotate the fastener within the transverse lumen, wherein the indented pattern is tilted with respect to the head so that the tip portion of the tool can be inserted into the indented pattern at an angle with respect to the transverse lumen, wherein the angle is in a range from 20 to 85 degrees as measured between a longitudinal axis of the tool and a plane that contains the longitudinal axis of the lead lumen and is perpendicular to the transverse lumen.
