Abstract
A lithotripsy device includes an elongate body comprising a distal tip portion having an end surface that forms a non-zero angle with a longitudinal axis of the elongate body, a balloon circumferentially around a portion of the elongate body enclosing the end surface of the tip portion defining an interior configured to receive a fluid, and at least one emitter positioned at the end surface of the tip portion of the elongate body. The at least one emitter is configured to generate pressure waves in the fluid propagating through the balloon to disintegrate a calcified lesion. A method of using a lithotripsy device is also provided.
Claims15
A lithotripsy device, comprising:
- an elongate body comprising a distal tip portion having an end surface that forms a non-zero angle with a longitudinal axis of the elongate body;
- a balloon circumferentially around a portion of the elongate body and enclosing the end surface of the tip portion, the balloon defining an interior configured to receive a fluid;
- and
- at least one emitter positioned at the end surface of the tip portion of the elongate body, the at least one emitter being configured to generate pressure waves in the fluid propagating through the balloon to disintegrate a calcified lesion
- wherein the elongate body comprises a tubular body having an inner surface defining a first lumen, and wherein the balloon comprises a distal end portion secured to the inner surface of the tubular body.
A lithotripsy device, comprising:
- an elongate tubular body comprising a distal tip portion having an end surface that forms a non-zero angle with a longitudinal axis of the elongate tubular body and a generally cylindrical portion adjacent to the tip portion;
- a balloon circumferentially around a portion of the elongate tubular body and enclosing the tip portion and the generally cylindrical portion, the balloon defining an interior configured to receive a fluid;
- and
- at least one emitter positioned at the end surface of the tip portion and one or more emitters positioned at an outer surface of the generally cylindrical portion, the at least one emitter and the one or more emitters being configured to generate pressure waves in the fluid propagating through the balloon to disintegrate a calcified lesion,
- wherein the elongate tubular body comprises an inner surface defining a first lumen and an outer surface, the balloon comprises a distal end portion, a proximal end portion, and a distensible portion, the distal end portion being secured to the inner surface of the elongate tubular body and the proximal end portion being secured to the outer surface of the elongate tubular body.
