Abstract
A device for vascular denervation comprising a catheter for insertion into a vessel, at least one elongated catheter arm having alternating regions of flexible joints and rigid blocks along the at least one catheter arm, wherein each of the at least one catheter arm comprises at least one tactile sensor and at least one temperature sensor; at least one electrode and electrical circuitry disposed on each of the at least one catheter arm and at least one linkage connected to all of the elongated catheter arms. A method for batch fabricating a plurality of catheter arms for the vascular denervation device is also provided and comprises the steps of depositing a first polymer coating on a semiconductor substrate, forming metal traces on the first polymer coating, patterning and etching the substrate to the first polymer coating to create flexible joint regions.
