Distal tip protector cap
First Claim
1. A protective device for the distal electrode of an implantable medical lead having a plurality of outward angularly extending tines comprising:
- a cap member extending between a nose end having a chamber for freely receiving therein the distal electrode of the medical lead and a tail end distant from said nose end; and
retention means at said tail end for releasably positively gripping the tines of the medical lead preventing relative rotation between said cap member and the distal electrode and inhibiting unintended removal of said cap member from the distal electrode.

Abstract
A protective device includes a cap member extending between a nose end having a chamber therein for freely receiving the distal electrode of an implantable medical lead having a plurality of outward angularly extending tines and a tail end and an integral conical shield defining a cavity at least partially protectively enveloping the tines. Retention members releasably attach the cap member to the distal electrode so as to inhibit its unintended removal and include a plurality of resilient elongated fingers of a silicone elastomer at the tail end equal in number to the tines at circumferentially spaced locations about a longitudinal axis of the device. Each adjacent pair of fingers is constructed so as the snappingly receive and capture the tine in engagement therewith such that removal of the tine from the retention recess by movement of the cap member in the opposite direction is positively inhibited by the transverse edges.
