Abstract
Some embodiments of a rotational atherectomy and lithotripsy system can partially or completely remove a stenotic lesion in blood vessels by rotating one or more abrasive elements to abrade and breakdown the lesion, by emitting acoustic energy to fracture and breakdown the lesion, or a combination of both.
Claims20
A device for removing stenotic lesion material from an artery of a patient, the device comprising:
- an elongated flexible drive shaft defining a longitudinal axis and comprising a torque-transmitting coil of one or more filars;
- eccentric abrasive burrs fixedly mounted on a distal end portion of the torque-transmitting coil;
- and
- one or more lithotripsy emitters fixedly mounted on the distal end portion of the torque-transmitting coil, each of the lithotripsy emitters configured to selectively emit acoustic energy.
A rotational atherectomy and lithotripsy device, comprising:
- an elongated flexible drive shaft defining a longitudinal axis and comprising a torque-transmitting coil of one or more filars;
- one or more abrasive burrs fixedly mounted on a distal end portion of the torque-transmitting coil;
- and
- one or more lithotripsy emitters configured to selectively emit acoustic energy and positioned proximate to the one or more abrasive burrs such that all of the one or more abrasive burrs and the one or more lithotripsy emitters are longitudinally advanceable together with the elongated flexible drive shaft.
A device configured to apply both rotational atherectomy and lithotripsy, comprising:
- a control handle assembly;
- a torque-transmitting coil extending distally from the control handle assembly;
- one or more abrasive burrs fixedly mounted on a distal end portion of the torque-transmitting coil;
- and
- one or more lithotripsy emitters positioned proximate to the one or more abrasive burrs, wherein the control handle assembly is configured to activate rotation of the one or more abrasive burrs at a targeted arterial site and to activate the one or more lithotripsy emitters to output acoustic energy at the targeted arterial site.
