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.

Abstract: Disclosed is a catheter comprising a first support member located near the distal end of the catheter and having a first hollow with both open ends; a second support member located near the proximal end of the catheter in comparison to the first support member and having a second hollow with both open ends; an operating tube configured to elongate in one direction; at least one connection member having one end connected to the first support member and the other end connected to the second support member; and a shaft body located near the proximal end of the catheter in comparison to the second support member to elongate in one direction, the shaft body having a fourth hollow with both open longitudinal ends so that the operating tube is inserted therein and movable in the longitudinal direction.
