Abstract
An apparatus for protection of a distal balloon on a dilatation catheter includes an inner compressible sleeve which fits longitudinally over the balloon, an outer compressible sleeve which fits over the inner sleeve, and a housing arrangement for deforming the sleeves radially inwardly about the balloon. The housing arrangement includes first and second threadably mated members which have longitudinally aligned throughbores for receiving the catheter and sleeves, but which act, when threaded together, to compress the outer sleeve onto the inner sleeve and the balloon.
