An intra-aortic balloon includes a flexible catheter having a deformable fitting closing one terminus and a connecting attachment at the other end. Adjacent the fitting, the catheter has a number of perforations all within an elongated balloon surrounding the perforations. One end of the balloon is secured to the fitting and at the other end is secured to the catheter. The connecting attachment is engageable with a removable body to which is secured a manually deformable wire extending through the catheter and into the fitting. The body has a duct open to the interior of the catheter and to the atmosphere. An outwardly opening check valve is in the duct.
