Abstract
A system for delivering mechanical waves to treat a lesion present in a vessel of a body, including an external mechanical wave source for generating mechanical waves from outside of the body, and a wave directing device insertable in the vessel, the wave directing device configured to receive the mechanical waves generated by the external mechanical wave source and to redirect the mechanical waves according to a target direction.
Claims17
A system for delivering high amplitude and broadband pulsed mechanical waves to treat a lesion present in a vessel of a body, comprising:
- an external mechanical wave source configured for generating high amplitude and broadband pulsed mechanical waves from outside of the body, the high amplitude and broadband pulsed mechanical waves having an amplitude between 10 MPa and 1000 MPa and a duration of 1/fc, fc being a center frequency between 20 kHz and 10 MHz;
- and
- a wave refractor device insertable in the vessel, the wave refractor device comprising at least one inflatable balloon comprising a respective fluid having a respective acoustic impedance, the wave refractor device being positionable and orientable within the vessel independently from and relative to the external mechanical wave source, the wave refractor device being configured for receiving the high amplitude and broadband pulsed mechanical waves generated by the external mechanical wave source and act as an acoustic lens by refracting and concentrating the high amplitude and broadband pulsed mechanical waves towards a focus point according to a target location by changing a shape of the at least one inflatable balloon via the respective fluid, the wave directing device being positionable and orientable inside the vessel relative to the lesion for selecting the target location during treatment for redirecting the high amplitude and broadband pulsed mechanical waves to the focus point to treat the lesion.
A method for treating a lesion, comprising:
- inserting a wave refractor device into a vessel of a body, the wave refractor device comprising at least one inflatable balloon comprising a respective fluid having a respective acoustic impedance, the vessel comprising a lesion to be treated;
- positioning the wave refractor device adjacent to the lesion to be treated, the positioning comprising orienting the wave refractor device relative to an external mechanical wave source located outside of the body;
- generating high amplitude and broadband pulsed mechanical waves using the external mechanical wave source and propagating the high amplitude and broadband pulsed mechanical waves towards the wave refractor device, the high amplitude and broadband pulsed mechanical waves having an amplitude between 10 MPa and 1000 MPa and a duration of 1/fc, fc being a center frequency between 20 kHz and 10 MHz;
- and
- at the wave refractor device, positioning, orienting and changing a shape of the inflatable balloon of the wave refractor device to refract and concentrate the high amplitude and broadband pulsed mechanical waves according to a selected location towards a focus point on the lesion to be treated.
