Multi-function lead implant tool
First Claim
1. An implant tool for use with an implantable lead, the implant tool comprising:
- a main body having a distal clamping section, a proximal section, and an interior lumen, the distal clamping section including an opening adapted to frictionally receive a terminal boot of the implantable lead;
a plurality of spring contact members coupled to the main body and exposed on an exterior of the implant tool; and
a knob mechanism coupled to the main body, the knob mechanism slidably actuatable along a central axis of the implant tool between a first position configured to frictionally engage a terminal pin of the implantable lead and a second position configured to disengage the implant tool from the terminal pin to facilitate torque release, the knob mechanism connected to the main body in each of the first and second positions, the knob mechanism configured to rotate relative to the main body when in the first position to rotate the terminal pin relative to the terminal boot, the knob mechanism slidably actuatable between the first and second positions independent of relative rotation between the knob mechanism and the main body, wherein the knob mechanism slides along the central axis, farther away from the main body, when slidably actuated from the first position to the second position.

Abstract
Devices, systems, and methods for implanting and testing multi-conductor electrical leads are disclosed. An illustrative implant tool for use with an implantable lead includes a main body, a plurality of spring contact members, and a knob mechanism. The main body of the implant tool includes a distal clamping mechanism with an opening adapted to frictionally receive a terminal boot of the implantable lead. The spring contact members are configured to provide an interface for connecting electrical connectors from a Pacing System Analyzer (PSA) or other testing device to the terminal contacts on the implantable lead. A knob mechanism coupled to the main body can be actuated to engage a terminal pin of the implantable lead, allowing an implanting physician to engage a fixation helix into body tissue by rotating the mechanism.

17. A system for implanting and testing an implantable lead within the body of a patient, the system comprising:
-
an implantable lead comprising a terminal pin, a terminal boot, and a fixation helix that is extendable from the implantable lead by relative rotation between the terminal boot and the terminal pin; and an implant tool comprising; a main body having a distal clamping section, a proximal section, and an interior lumen, the distal clamping section including an opening adapted to frictionally receive the terminal boot of the implantable lead; a plurality of spring contact members coupled to the main body; and a knob mechanism coupled to the main body, the knob mechanism slidably actuatable along a central axis of the implant tool between a first position configured to frictionally engage a terminal pin of the implantable lead and a second position configured to disengage from the terminal pin, wherein the knob mechanism slides along the central axis, farther away from the main body, when slidably actuated from the first position to the second position, wherein the knob mechanism is configured to rotate the terminal pin relative to the terminal boot, while the terminal boot is held by the distal clamping section and while the knob mechanism is in the first position, to extend the fixation helix from the implantable lead. - View Dependent Claims (18, 19)
