1. A lead evaluation device configured for connection to a proximal portion of an implantable lead having a terminal boot, a plurality of terminal contacts and a terminal pin, the lead evaluation device comprising:
- a main body including an opening configured to frictionally engage the terminal boot, the main body including a first side and an opposing second side;
a channel extending through the main body from the opening, the channel configured to accommodate the proximal portion of the implantable lead including the plurality of terminal contacts; and
a plurality of terminal contact clips coupled to the main body such that each of the plurality of terminal contact clips, having one or more external ridges extending horizontally along the terminal contact clip and configured to provide a contact for an alligator clip and one or more internal ridges arranged extending vertically along the terminal contact clip, wherein each of the plurality of terminal contact clips are biased into a relaxed configuration and positioned to releasably make electrical contact with a corresponding one of the plurality of terminal contacts via the one or more internal ridges when the implantable lead is disposed within the channel and in response to a force applied by placing the alligator clip.

Abstract
A multipolar lead evaluation device may be configured to easily permit electrical contact to be made between a pacing system analyzer and the terminal pin and each of the terminal contacts of an implantable lead without damaging the implantable lead. Alligator clips may be used to secure electrical conductors from the pacing system analyzer to spring contact clips disposed within the lead evaluation device.

12. A method of testing an implantable lead during or after implantation, the implantable lead including a terminal boot, a plurality of terminal contacts and a terminal pin, the method comprising:
-
frictionally engaging the terminal boot of the implantable lead with a lead evaluation device including; a main body including an opening configured to frictionally engage the terminal boot, the main body including a first side and an opposing second side; a channel extending through the main body from the opening, the channel configured to accommodate the proximal portion of the implantable lead including the plurality of electrodes; and a plurality of terminal contact clips coupled to the main body such that each of the plurality of terminal contact clips, having one or more external ridges extending horizontally along the terminal contact clip and configured to provide a contact for an alligator clip and one or more internal ridges arranged extending vertically along the terminal contact clip, wherein each of the plurality of terminal contact clips are biased into a relaxed configuration and are positioned to releasably make electrical contact with a corresponding one of the plurality of terminal contacts via the one or more internal ridges when the implantable lead is disposed within the channel and in response to a force applied by placing the alligator clip; securing an alligator clip onto each of the plurality of terminal contact clips, each of the alligator clips being electrically connected to a pacing system analyzer; and testing the implantable lead with the pacing system analyzer.
