Devices, methods and systems for transmitting signals through a device located in a blood vessel of an animal, for stimulating and/or sensing activity of media proximal to the device, wherein the media includes tissue and/or fluid.

Medical device for sensing and or stimulating tissue

A neurostimulation device with ultrasound transducer elements is disclosed. The ultrasound transducer elements may be adapted for endoluminal delivery to a deployment site in a lumen of the substrate. The transducer elements may be used to focus acoustic energy, by controlling either the phase delay, time delay, or both, or the ultrasound signals. Further, the plurality of transducer elements may be arranged in a grid arrangement having at least two dimensions.

Neurostimulation using endoluminal focussed ultrasound

The present disclosure relates to a method for determining stimulation parameters for a neuroprosthetic device performed by a processor of the device. Based on (i) a desired spatial pattern of neural activity, the processor determines stimulation parameters for an array of electrodes of the neuroprosthetic device. The processor determines the stimulation parameters such that a difference between (i) the desired spatial pattern of neural activity and (ii) an estimated spatial pattern of neural activity is optimised. The estimated spatial pattern of neural activity is an estimate of a response of a target neural tissue to being stimulated by the neuroprosthetic device based on the stimulation parameters. This method allows higher resolution stimulation and allows electrode arrays with higher electrode density to be usefully employed.
