Abstract
An intravascular lithotripsy device may include an elongate shaft, at least one wave generator, and at least one expandable member extending around the at least on wave generator. The at least one expandable member may be inflatable with a fluid. The at least one expandable member may have a plurality of lobes, including a first lobe and a second lobe longitudinally spaced from the first lobe. The at least one expandable member may have a sinusoidal shape. A power generator may be electrically coupled with the at least one wave generator and configured to actuate the at least one wave generator to initiate a wave within the at least one expandable member.
Claims20
A medical device, the medical device comprising:
- an elongate shaft;
- at least one wave generator;
- and
- at least one expandable member extending around the at least one wave generator,
- wherein the at least one expandable member has a plurality of lobes including a first lobe and a second lobe longitudinally spaced from the first lobe.
A system comprising:
- a catheter comprising:
- an elongate shaft;
- at least one wave generator;
- and
- at least one expandable member extending around the at least one wave generator, and
- wherein the at least one expandable member comprises a sinusoidal shape when inflated;
- and
- a power generator configured to actuate the at least one wave generator to initiate a wave within the at least one expandable member.
A method for treating a stenosis in a body lumen, the method comprising:
- advancing a catheter within the body lumen to a position proximate to the stenosis, the catheter comprising an elongate shaft, at least one wave generator, and at least one expandable member extending around the at least one wave generator and having a plurality of lobes;
- inflating the at least one expandable member with a fluid so that an outer surface of an apex of at least one of the plurality of lobes contacts the stenosis;
- and
- actuating the at least one wave generator to generate at least one wave through the fluid and the apex of the at least one of the plurality of lobes.
