ABSTRACT:
A flexible tip catheter for electrically stimulating the heart comprising an elongated body having an elongated passage therein and an elongated 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 distal end portion is more flexible at distal locations than at proximal locations along its length. The flexibility of the distal end portion and of the electrode greatly reduces the risk of penetration of the heart wall.
