Catheter and a method for producing a catheter

摘要

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 tape (118) are wrapped around the catheter (100) and are severed from the connecting portions (112,113). Free ends (115) of the electrically conductive elements (114) abut each other to form the electrodes (5) as band electrodes.

1. A method for producing a catheter with a plurality of spaced apart electrodes thereon, the method comprising:
forming the electrodes from respective electrically conductive elements, the electrically conductive elements being formed from a single sheet of electrically conductive material with the electrically conductive elements being spaced apart from each other and being joined by connecting portions formed by portions of the single sheet of electrically conductive material between the electrically conductive elements, the electrically conductive elements being of length sufficient to extend at least partly around the catheter, bonding the electrically conductive elements to the catheter with the electrically conductive elements being joined by the connecting portions and extending at least partly around the catheter, and severing each connecting portion from at least one of the electrically conductive elements which are joined by the connecting portion subsequent to the electrically conductive elements being bonded to the catheter to form the electrodes thereon.
