Optimized therapeutic energy delivery
10843012 · 2020-11-24 · ·

An ultrasound apparatus is described for externally treating kidney stone in human body. The apparatus has one or more ultrasound imaging transducers, a therapeutic ultrasound transducer, and a processing unit. Optimized delivering of ultrasound energy to the kidney stone from the therapeutic ultrasound transducer is based on real-time tracked state (e.g., position, movement shape, size, or combination thereof) of the kidney stone. The ultrasound imaging transducer(s) is configured to image the stone during the application of the therapy treatment. An optimization algorithm is implemented to control the therapeutic ultrasound transducer to apply different force vectors to the region of the stone. The effect of the vectors in the differing directions with respect to the stone may be detected and input to the optimization algorithm, which optimizes the therapy by adjusting one or more of the vectors. Therefore, less ultrasound energy may be delivered to break the kidney stone, and may reduce the possibility of damaging the surrounding tissues of the kidney stone.

Extracorporeal shockwave lithotripsy (ESWL) system and method using in-situ sensing of system and device data and therapeutic/system/device level control

The present invention provides enhanced ESWL efficacy for therapeutic and operational outcomes. Device behavior and performance data is measured in-situ and analyzed for both intra-procedure and inter-procedure breadth of regard such that both therapy optimization and maintenance optimization engines are provided an accurate and current assessment of ESWL system and device state and performance. This feedback and control provides the ability to compensate in real time for the current patient therapy and offline for future patient therapy for machine/therapy idiosyncrasies and realize continuous calibration of system/devices to the performance required for maximum ESWL patient efficacy.

According to one aspect, an exemplary method comprises: transmitting to a processing unit, with an imaging element mounted on a distal end of a scope, image data about a stone object inside a body cavity; generating from the image data, with the processing unit, a visual representation of the stone object and the body cavity; establishing from a user input, with the processing unit, a scale for the visual representation; determining from the visual representation, with the processing unit, a size of the stone object on the scale; comparing, with the processing unit, the size of the stone object with a predetermined maximum size to determine a removal status; and augmenting, with the processing unit, the visual representation to include an indicator responsive to the removal status. Associated systems are also described.

CONFINEMENT OR MOVEMENT OF AN OBJECT USING FOCUSED ULTRASOUND WAVES TO GENERATE AN ULTRASOUND INTENSITY WELL

A method includes transmitting a focused ultrasound wave into a medium to form (i) an ultrasound intensity well within the medium that exhibits a first range of acoustic pressure and (ii) a surrounding region of the medium that surrounds the ultrasound intensity well and exhibits a second range of acoustic pressure that exceeds the first range of acoustic pressure. The method further includes confining an object within the ultrasound intensity well. Additionally, an acoustic lens is configured to be acoustically coupled to an acoustic transducer. The acoustic lens has a varying longitudinal thickness that increases proportionally with respect to increasing azimuth angle of the acoustic lens. Another acoustic lens is configured to be acoustically coupled to an acoustic transducer. The acoustic lens includes a plurality of segments. Each of the plurality of segments has a varying longitudinal thickness that increases proportionally with respect to increasing azimuth angle of the segment.
