Module for controlled switching of a multielectrode probe for an active implantable medical device

摘要

The module (40) has a non-volatile programmable memory component (68) including two stable states, where each state controls an opened or closed state of controlled switches (52, 54), respectively. A decoding circuit (72) comprises a programming unit programming prior to the stable state using signals applied by a generator to a two-wire line. A switching circuit includes a generator maximum-minimum circuit (58) coupled between proximal and distal terminals at an input, and coupled with the switches at output to selectively control the switches and the terminals using the component. The non-volatile programmable memory component is a suspended nanotube cell and a magnetic tunnel junction cell. An independent claim is also included for a probe for an active implantable medical device.
