<p>An intracorporeal heart assisting device which comprises a balloon (1) having a changeable inner capacity and a pipe (2) having one of the ends thereof closed so as to feed and discharge a gas into and from inside the balloon. The balloon is fixed to the pipe in such a manner as to embrace a predetermined length of a portion near that end of the pipe, and at least one hole (23) for feeding and discharging a gas is bored in the peripheral wall (22) of the portion embraced by the balloon in a longitudinal direction. The present invention can provide, to a patient of serious heart failure, an intracorporeal heart assisting device which (1) applies a small load (non-thoracotomy and non-pericardotomy, and small influence on respiration and less pain), (2) uses a simple feed device and (3) can assist the heart reliably for a long period of time.</p> |
