Abstract:
1. A lead fixation tool comprising: a proximal portion having a tapered passage there through, with the tapered passage narrowing in a direction towards a distal portion; and a distal portion having a channel in substantially axial alignment with the passage along a longitudinal axis, wherein the proximal portion and the distal portion are rotatably coupled so that relative rotation is permitted between the proximal portion and the distal portion; and an expandable lead pin engagement mechanism disposed within the channel, wherein the engagement mechanism is a C-shaped interference clamp that is axially aligned with the passage and to grip a lead connector assembly and remain at a fixed location on said longitudinal axis during said relative rotation of said proximal and distal portions; and a rotation indicator for indicating relative rotation between the proximal and distal portions the rotation indicator includes: a resilient arm having an actuator; and a detent, wherein rotation of the distal portion relative to the proximal portion causes the actuator to engage the detent and provide a signal.
