Abstract
A method for producing a catheter (100) having a plurality of axially spaced apart electrodes (5) towards a distal end (4) of the catheter (100) comprises forming the electrodes (5) from a single sheet (110) of electrically conductive foil material by forming spaced apart slots (111) in the sheet material to define a plurality of spaced apart electrically conductive elements (114) extending transversely between spaced apart elongated connecting portion (112,113). The electrically conductive elements (114) subsequently form the electrodes (5), and are retained spaced apart by the connecting portions (112,113) until bonded to the catheter (100). Electrically conductive wires (10) electrically coupled to the electrically conductive elements (114) extend through an elongated slot (105) into and along an axial communicating bore (9) to a proximal end (3) of the catheter (100). Two pieces of double-sided adhesive tape (118) bonded to the electrically conductive elements (114) in turn bond the electrically conductive elements (114) to the catheter (100). After entering the wires (10) into the axial communicating bore (9) the electrically conductive elements (114) with the double-sided tap…
