Abstract
A multi-contact electrode device, comprising an elongated body with plurality of pick-up contacts and a slender ASIC into a hollow lumen. The ASIC is configured to readout, process and digitize the EEG signals present at the contacts and to apply selectively a high RF current to any selected pair of contacts for thermocoagulation. The ASIC also includes a microcontroller with a digital communication interface.
Claims13
A multi-contact electrode device, comprising an elongated body with a distal end for placement into a target region of a patient's body, the device comprising a plurality of pick-up contacts on an active portion of the elongated body adjacent the distal end for recording an electrical activity of the target region and for delivering a radiofrequency current into the target region, the elongated body containing, in the active portion, an integrated circuit that comprises:
- a readout unit with a plurality of input channels, configured
- for amplifying and digitizing electrical signal impressed on at least some of the pick-up contacts by the electrical activity of the target region, p1 a thermocoagulation unit receiving a radiofrequency signal, selectively connectable to at least one selected contact out of the pick-up contacts for injecting a localized radiofrequency current into the target region,
- a digital communication interface.
The device of claim 2, wherein the integrated circuit has two 20 more preferably equal to or lower than 0.75 mm.
An integrated circuit comprising,
- a readout unit with a plurality of terminals connectable to pick-up contacts, configured for processing and digitizing bio-electrical signals picked up by the pick-up contacts,
- an input for a radiofrequency signal, selectively connectable to at least one selected terminal from the terminals for injecting a localized radiofrequency current into a target region near a pick-up contact,
- a digital communication interface,
- wherein the integrated circuit has two linear dimensions lower than 2 mm, preferably lower than 1 mm, more preferably equal to or lower than 0.75 mm.
