Apparatus, a system and a method for stimulating a part of a peripheral nervous system

An apparatus for stimulating a part of a peripheral nervous system, said apparatus comprising:

• a sensor unit comprising at least one ultrasound transducer and at least one pair of electrodes configured to be arranged in different locations in relation to the part of the peripheral nervous system, wherein the at least one ultrasound transducer is configured to transmit ultrasound into the part of the peripheral nervous system and wherein the at least one pair of electrodes is configured to detect electrical signals in the part of the peripheral nervous system, wherein the sensor unit is configured to determine structural information of the part of the peripheral nervous system and functional information of the part of the peripheral nervous system based on at least one sensing mode of the sensor unit, wherein the sensor unit is configured to, in the at least one sensing mode, perform ultrasound detection and/or electrical signal detection based on transmitting ultrasound into the part of the peripheral nervous system;
• a stimulation unit configured to transmit a stimulation signal into the part of the peripheral nervous system for selective stimulation of a position within the part of the peripheral nervous system;
• and
• a controller configured to receive the structural information and the functional information and configured to control a location of the selective stimulation of the position within the part of the peripheral nervous system based on the structural information and the functional information.
