Extendable and retractable lead having a snap-fit terminal connector
First Claim
Patent Images
1. A lead for a medical device, the lead comprising:
- a lead body extending from a distal end portion to a proximal end portion;
at least one conductor disposed within the lead body and extending from the proximal end portion;
an electrically conductive terminal pin disposed at the proximal end portion of the lead body, the electrically conductive terminal pin having at least recess;
an insulative sleeve coupled with the electrically conductive terminal pin with a snap-fit connection; and
the snap-fit connection includes a rotatable snap-fitted connection that allows rotation of the terminal pin relative to the sleeve after the sleeve is snap-fittedly coupled with the terminal pin, and the terminal pin is rotatable relative to the sleeve.

Abstract
A lead having an extendable and retractable fixation mechanism has a rotating terminal pin at the terminal end which rotates the fixation mechanism at the distal end. As the terminal pin is rotated, the fixation mechanism is extended or retracted from the distal end of the lead. A threaded collar allows for the fixation mechanism to smoothly extend and retract from the lead, and allows for a 1:1 turn ratio between the terminal pin and the fixation mechanism. A fluoroscopic ring disposed at the distal end of the lead provides information during the implantation process.
