A dilatation catheter has a shaft (S) comprising a tube (1) of braided material encapsulated over a major portion of its length in an outer coating (2) of semi-rigid inelastic material. An outer coating (3) of elastic material extends over a minor portion of the length of the shaft at or near its distal end. An inner coating (4) of elastic material may be provided over the entire length of the inside of the tube (1). The distal end portion of the catheter is inflatable by pressure applied from within the shaft to form a balloon. Radio-opaque markers (5a and 5b) may be provided at each end of the inflatable portion. <IMAGE> |
