Abstract
A catheter, preferably a balloon-type catheter, is disclosed in which the catheter shaft is made of a thermoplastic material and thus may be extrudable, the shaft consisting essentially of (a) from 40 to 70 percent by weight of an elastic composition which comprises: from 50 to 99.5 percent by weight of a block copolymer having thermoplastic rubber characteristics with a central, rubbery polyolefin block and terminal blocks of polystyrene, and optionally including up to about 45 percent by weight of polypropylene, plus from 0.5 to 10 percent by weight of a cross-linked organic silicone elastomer; and (b) from 30 to 60 percent by weight of a hydrophobic oil-type plasticizer to provide the desired degree of softness to said elastic composition.
