SYSTEM AND METHOD FOR COMMINUTION OF BIOMINERALIZATIONS USING MICROBUBBLES
20210015511 · 2021-01-21 ·

A system and method for ultrasound treatment is presented. The system and method alternatingly provide microbubbles in a target region containing a biomineralization, then insonate the microbubbles using an external ultrasound source. The microbubbles cavitate in the target region, destructively affecting the biomineralization and potentially breaking it or reducing its mass over time as a result of the cavitation action. Spatial orientation or alignment of the external ultrasound source may be achieved for best results using acoustic signatures and spectral representations of the same.

DEVICE AND METHOD FOR LUNG TREATMENT
20210000524 · 2021-01-07 ·

This invention relates to the treatment of a patient's lung, for example, a lung exhibiting chronic obstructive pulmonary disease (COPD) and in particular to methods and devices for affecting lung volume reduction, preferably for achieving acute or immediate lung volume reduction following treatment. The lung volume reduction is effected by delivering a condensable vapor at a temperature above body temperature to the desired regions of the patient's lung to damage tissue therein. Blood flow and air flow to the damaged tissue region is essentially terminated, rendering the target region non-functional. Alternative energy sources may be used to effect the thermal damage to the lung tissue.

Cancer treatment methods using thermotherapy and/or enhanced immunotherapy are disclosed herein. One two-stage cancer treatment method comprises the steps of: (i) in a first stage, administering, to a patient with a metastatic malignancy, tumor-antibody-coated nanoparticles conjugated with one or more medications and/or one or more immune stimulators for attaching to circulating exosomes, extracellular vesicles, and/or circulating tumor cells, thus promoting a destruction of the circulating exosomes, extracellular vesicles, and/or circulating tumor cells by a cellular immune system of the patient; and (ii) in a second stage, treating a main tumor of the patient during the same session or during another session of therapy by administering the tumor-antibody-coated nanoparticles conjugated with the one or more medications and/or the one or more immune stimulators so as to stimulate the cellular immune response of the patient to destroy the main tumor.

METHODS AND SYSTEMS FOR USING PHASE CHANGE NANODROPLETS TO ENHANCE SONOTHROMBOLYSIS
20200405258 · 2020-12-31 ·

A method for using metastable perfluorocarbon nanodroplets for ultrasonic lysis of blood clots includes administering metastable perfluorocarbon nanodroplets into a blood vessel that includes or that leads to a blood vessel that includes a blood clot, the metastable perfluorocarbon nanodroplets each have a liquid core comprising a perfluorocarbon material that has a boiling point below 25 C. at atmospheric pressure and that remains stable in liquid form at 25 C. at atmospheric pressure. The method further includes applying ultrasound energy to the perfluorocarbon nanodroplets within or surrounding the blood clot, causing the perfluorocarbon nanodroplets to vaporize and convert to bubbles, which cavitate and lyse the blood clot.

CONTROL OF EXOGENOUS AGENT CHARACTERISTICS IN MICROBUBBLE-MEDIATED ULTRASOUND PROCEDURES
20200391019 · 2020-12-17 ·

Various approaches for microbubble-enhanced ultrasound treatment of target tissue include retrieving a treatment plan stored in memory; causing administration of an exogenous agent in accordance with the treatment plan; causing, in accordance with the treatment plan, an ultrasound transducer to transmit ultrasound waves to the target tissue and generate a focus therein in the presence of administered exogenous agent; receiving, from a monitoring system, a measured parameter value indicating a treatment condition in response to administration of the exogenous agent and transmission of the ultrasound waves during treatment; and adjusting the treatment plan based at least in part on the measured parameter value.

Ultrasonic lesion feedback, antipop monitoring, and force detection

An ablation catheter comprises: an elongated catheter body extending longitudinally between a proximal end and a distal end along a longitudinal axis; a distal member disposed adjacent the distal end, the distal member including an ablation element to ablate a biological member; one or more acoustic transducers disposed in the distal member and each configured to direct an acoustic signal toward a respective target ablation region and receive reflection echoes therefrom; and an acoustic redirection member disposed in the distal member to at least partially redirect the acoustic signal from at least one of the acoustic transducers toward a tissue target. The distal member includes a most-distal portion, a proximal portion, and a deflectable portion between the most-distal portion and proximal portion to permit deflection between the most-distal portion and proximal portion of the distal member. The transducers and redirection member are mounted on opposite sides of the deflectable portion.
