Abstract

A multichannel clip device and methods of use that facilitate connection of multiple electrical components of a first device and a second device for testing and/or verification are provided herein. Such multichannel clip devices can include a spring-loaded clip having multiple electrical contacts for coupling with a contact portion of a first device and which are connected to a proximal connector through a flexible stimulation cable. The contacts can be included within a neurostimulation lead connector and the proximal connector adapted to couple with standard connectors on a clinician programmer, each contact being coupled to a corresponding contact of the proximal connector to define multiple separate channels. Such clip devices allow clinicians to test and/or verify multiple neurostimulation lead electrodes with a clinician programmers without requiring separate connection of each electrodes to a probe or test device and further allows for repeated sequencing or multi-plexing of neurostimulation leads during testing.
