IMPLANTABLE MULTIELECTRODE MICROPROBE USING SHAPE MEMORY ALLOY

摘要

The present invention relates to an implantable multielectrode microprobe comprising at least one element (7) of a shape memory alloy extending from a first end along a longitudinal axis towards a second end of the microprobe (1). The electrodes (9) and the element (7) are embedded in a polymer encapsulation (6). The element (7) of shape memory alloy of the proposed microprobe (1) is designed to be stiff at higher temperatures and flexible at lower temperatures, Such a microprobe (1) can be made stiff when inserted into the cerebral cortex and changes its mechanical properties to be flexible inside the cortical tissue.
