  • Patent number: 11904119
    Abstract: Balloon catheter includes an outer shaft having a hypotube and a monolithic single-layer distal outer member, a balloon in fluid communication with an inflation lumen, and a monolithic inner tubular member having a guidewire lumen defined therethrough. The outer shaft has the inflation lumen defined therethrough. The monolithic single-layer distal outer member is necked to a reduced diameter along an entire length thereof. A proximal end of the monolithic single-layer distal outer member is coupled to the hypotube. A distal section of the hypotube comprises a skive defined by a first angled cut, an axial cut, and a second angled cut. The balloon has a proximal balloon shaft coupled to a distal end of the monolithic single-layer distal outer member. The monolithic inner tubular member extends distally from a proximal port in the monolithic single-layer distal outer member through the balloon to form a tip.
