Methods, devices, and systems are disclosed for affixing and orienting an ultrasound transducer to a patient. A mount has a base, with a top surface, a bottom surface, an outer surface, and a plurality of internal surfaces. Some of the internal surfaces define a number of through holes that pass through the top surface and the bottom surface at the periphery or outer edge of the base. A number of supports are also arranged on the outer surface of the housing to affix the mount to the patient, to affix the transducer to the mount, or both. At least one of the plurality of internal surfaces defines a channel between the top and bottom surfaces proximal to a center of the mount, which receives a transducer and directs the transducer head toward the patient.

SYSTEMS AND METHODS FOR APPLYING ENERGY TO DENERVATE A PULMONARY ARTERY

A catheter system for ablation of tissue around a blood vessel, e.g., the pulmonary artery, to reduce neural activity of nerves surrounding the blood vessel. The catheter system includes an elongate shaft having a proximal portion coupled to a handle, and a distal portion. The distal portion includes a transducer and an expandable anchor, which may be actuated to transition between a collapsed delivery state and an expanded deployed state where the anchor centralizes the transducer within the blood vessel. The transducer may be actuated to emit energy to reduce neural activity of the nerves surrounding the blood vessel. Systems and method are further provided for confirming that neural activity of the nerves surround the blood vessel has been sufficiently reduced.

System and method for controlling focused ultrasound treatment

A system and method for controlling the delivery of ultrasound energy to a subject is provided. In particular, such a system and method are capable of safely disrupting the blood-brain barrier. Ultrasound energy is delivered to produce cavitation of an ultrasound contrast agent at a selected pressure value. An acoustic signal is acquired following cavitation, from which a signal spectrum is produced. The signal spectrum is analyzed for the presence of harmonics, such as subharmonics or ultraharmonics. When subharmonics or ultraharmonics are present, the pressure value is decreased for subsequent sonications. If a previous sonication resulted in no subharmonics or ultraharmonics being generated, then the pressure value may be increased. In this manner, the blood-brain barrier can be advantageously disrupted while mitigating potentially injurious effects of the sonication.

Systems, devices, and methods for treating a pulmonary disease with ultrasound energy

A pulmonary treatment system includes a compact configuration for delivery to an airway of a patient. An energy delivery system of the pulmonary treatment system delivers ultrasound energy to target nerve tissue in or along an airway wall of the airway radially outward from surface tissue to reduce airway resistance in a downstream airway. The pulmonary treatment system may protect tissue in the airway wall of the airway located between the target nerve tissue and the ultrasound energy delivery system by a coolant system that may also act as a coupling fluid for the emitted ultrasound energy.

METHOD FOR MID-INTENSITY, NON-ABLATIVE ACOUSTIC TREATMENT OF INJURED TISSUE
20220288425 · 2022-09-15 ·

A method for mid-intensity non-ablative acoustic treatment of injured tissue is disclosed. The method involves continuously moving an ultrasound probe across an extracorporeal skin surface while emitting non-ablative therapeutic ultrasound into the injured tissue in a non-ablative therapeutic ultrasound beam profile. The method terminates energy delivery if movement speed is below a speed threshold. The non-ablative therapeutic ultrasound beam profile provides substantially uniform heating throughout a treatment volume. The heating is non-ablative and triggers a healing response in the injured tissue.

Transfection and drug delivery

An ultrasound transmitter device for treating a patient is provided. The ultrasound transmitter device includes an imaging probe; an imaging array; and a therapeutic ultrasound device, wherein the imaging probe is configured to guide the therapeutic ultrasound device to the patients treatment site by use of ultrasound imaging with the imaging array, wherein the therapeutic ultrasound device is configured to produce a controlled intensity of ultrasound energy for treating the patients treatment site, and wherein the imaging probe and the therapeutic ultrasound device are configured to work in conjunction with one another to apply therapeutic ultrasound to tissue or bone graft sites in the patient.
