Intracardiac Electrophysiology Stimulator/Amplifier

Overview

The Intracardiac Electrophysiology Stimulator/Amplifier is an integrated stimulator and amplifier that is specifically designed to work with Millar electrophysiology catheters (purchase separately) and an Instrument Interface and/or PowerLab data acquisition system for in vivo or in vitro intracardiac electrophysiology studies.
It is supplied with 1 m long cables that connect each analog output at the back of the stimulator/amplifier to a PowerLab BNC input
Other features include providing:

up to eight current and voltage-driven electrical stimulation channels
up to eight amplifier channels and software selectable gains
a TTL trigger for synchronization or basic communications with external devices
powerful MC_Stimulus II software with advanced features

The stimulator/amplifier requires the EPR Catheter Interface Cable (Redel, GND, 3 ft), for connecting an electrophysiology catheter to the stimulator/amplifier, and the EP Grounding Kit (Cable Set), for grounding purposes. Both cables are available and purchase separately. Additionally, a EPR Connecting Cable (Redel to Redel, 3ft) can also be purchased, if further extension between the stimulator/amplifier and the electrophysiology catheter is required. The stimulator/amplifier and relevant interfacing cables are also supplied when purchasing the Cardiac Electrophysiology System.
