Abstract
A wrapping system for an intra-aortic balloon in which a wrapping guide is provided which restrains the proximal end of the envelope from rotating as the distal end is rotated thereby providing a uniform wrap of the envelope from its distal to its proximal end. A wrapping wire is provided for rotating the envelope distal end and the wire extends through at least a part of the catheter to which the envelope is attached. A wrapping knob is coupled to the proximal end of the wrapping wire, whose distal end can be detachably coupled to the distal end of the envelope, and the knob is constructed to permit only a predetermined number of rotations in both wrapping and unwrapping the envelope.
