Co-radial lead with extendable/retractable fixation mechanism and apparatus therefor
First Claim
1. A lead assembly, comprising:
- a lead body extending from a lead proximal end portion to a lead distal end portion, the lead body including at least one conductor disposed therein;
an extendable and retractable active fixation mechanism disposed at the lead distal end portion;
a lead lumen extending within the lead body from the lead proximal end portion to at least an active fixation mechanism proximal end;
a driver removably and rotatably seatable within the lead lumen, the driver including a stylet or guidewire receiving lumen therein; and
the active fixation mechanism actuatable by rotation of the driver.

Abstract
A lead assembly comprises a lead body extending from a lead proximal end portion to a lead distal end portion with at least one conductor disposed therein. A lead lumen extends within the lead body and is dimensioned and configured to removably and rotatably seat a driver therein. The driver includes a driver body extending from a driver proximal end to a driver distal end and having a stylet or guidewire lumen disposed therein. An extendable and retractable active fixation mechanism is disposed at the lead distal end portion. The active fixation mechanism is actuatable by rotation of the driver. In one example, the at least one conductor includes a first conductor and a second conductor, in which the first conductor is co-radial with the second conductor. In another example, the driver distal end includes a portion extractably engagable with the lead distal end portion.
