Patent ID: 8532792

Claim:
An extraction tool assembly for use with an implantable active fixation lead having a proximal end, a rotatable terminal pin extending from the proximal end, a stylet lumen extending through the terminal pin, and a rotatable active fixation helix coupled an electrode base and to the terminal pin, the extraction tool assembly comprising: an extraction stylet flexible for insertion into a body lumen, the extraction stylet including a widened blade portion complementary to an extraction slot disposed within a proximal end of the electrode base; and an extraction tool including: a main body having a proximal section, a distal section and an intermediate section, a lumen extending through the main body, the lumen configured to accommodate an extraction stylet; a funnel formed within the proximal section configured to provide stylet access to the lumen extending through the main body; an opening formed within the distal section configured to frictionally engage a proximal end of the implantable lead, the opening aligned with the lumen extending through the main body; a lead locking device disposed within the distal section, the lead locking device configured to releasably secure the proximal end of the implantable lead relative to the extraction tool; a terminal pin locking device disposed within the intermediate section, the terminal pin locking device configured to releasably secure the terminal pin relative to the extraction tool; and a stylet locking device disposed within the proximal section, the stylet locking device configured to releasably secure the extraction stylet relative to the extraction tool.
