Abstract
Systems and methods for sonicating a body within an organ of a patient include supplying ultrasound energy to the body in order to produce a liquified material, which can then be aspirated from the body via a catheter. Image guidance is used during aspiration of the liquified material.
Claims27
A method of treatment comprising:
- configuring a system for facilitating magnetic resonance-guided focused ultrasound aspiration to sonicate a body within an organ of a patient, the system comprising:
- a transducer assembly comprising an array of ultrasound transducers adapted to deliver ultrasound energy, said transducer assembly at least partially defining a substantially liquid-tight jacket adapted to contain a fluid medium in order to conduct ultrasound waves;
- and
- an access port adapted to accommodate therethrough a guide tube emerging from said jacket, said guide tube configured to permit passage of a catheter therethrough such that the catheter may be positioned adjacent to the body;
- and
- sonicating the body with ultrasound energy supplied by at least one of the array of transducers of the system, thereby liquefying the body to produce liquified material;
- and
- aspirating the liquified material via the catheter;
- wherein said liquid tight jacket has been applied against and forms a seal with the patient such that said fluid medium is confined between the jacket and the patient, wherein both sonication of the body and positioning of the catheter adjacent thereto are assisted via image guidance, wherein said guide tube is made exclusively of substantially non-ferromagnetic materials.
A system to facilitate magnetic resonance-guided focused ultrasound aspiration comprising:
- a transducer assembly comprising an array of ultrasound transducers adapted to deliver ultrasound energy, said transducer assembly at least partially defining a substantially liquid-tight jacket adapted to contain a fluid medium in order to conduct ultrasound waves;
- and
- an access port adapted to accommodate therethrough a guide tube emerging from said jacket, said guide tube configured to permit passage of a catheter therethrough;
- wherein said guide tube is made exclusively of substantially non-ferromagnetic materials.
A system to facilitate magnetic resonance-guided focused ultrasound aspiration comprising:
- a transducer assembly comprising an array of ultrasound transducers adapted to deliver ultrasound energy, said transducer assembly at least partially defining a substantially liquid-tight jacket adapted to contain a fluid medium in order to conduct ultrasound waves;
- an access port adapted to accommodate therethrough a guide tube emerging from said jacket;
- and
- a catheter accommodated through said guide tube;
- wherein said guide tube is made exclusively of substantially non-ferromagnetic materials.
A system to facilitate magnetic resonance-guided focused ultrasound aspiration comprising:
- a transducer assembly comprising an array of ultrasound transducers adapted to deliver ultrasound energy, said transducer assembly at least partially defining a substantially liquid-tight jacket adapted to contain a fluid medium in order to conduct ultrasound waves;
- a diaphragm secured to the transducer assembly;
- and
- an access port provided through a membrane of the diaphragm and adapted to accommodate therethrough a guide tube emerging from said jacket;
- wherein said guide tube is made exclusively of substantially non-ferromagnetic materials.
