Open the CIPO recordAbstract From the Canadian patent
A flexible tip catheter for electrically stimulating the heart comprising an elongated body having an elongated passage therein and an enlongated conductor partially in the passage. The elongated conductor has a distal end portion outside of the passage which is flexible and resilient along its length. The distal end portion includes a flexible resilient electrode exposed at the outer periphery of the catheter so that current can be passed along the conductor to the electrode to electrically stimulate the heart. The flexibility of the distal end portion and of the electrode greatly reduces the risk of penetration of the heart wall.
