Treatment of subarachnoid hematoma using sonothrombolysis and associated devices, systems and methods
09808653 · 2017-11-07 ·

Methods for treating a human patient having a subarachnoid hematoma, such as to prevent cerebral vasospasm or to reduce the severity of cerebral vasospasm in the patient, and associated devices, systems, and methods are disclosed herein. In a particular embodiment, a thrombolytic agent is introduced extravascularly into a subarachnoid region including the hematoma. A headset configured for hands-free delivery of transcranial ultrasound energy is connected to the patient and used to deliver ultrasound energy to the subarachnoid region to enhance the thrombolytic effect of the thrombolytic agent. The type and/or dosage of the thrombolytic agent can be selected based on the enhanced thrombolytic effect. For example, the enhanced thrombolytic effect can allow the therapeutically effective use of less aggressive thrombolytic agents and/or lower dosages of thrombolytic agents. In some cases, this can reduce the clinical probability of additional cerebral hemorrhage.

20220233695 · 2022-07-28 ·

An ultrasound system for use in unbinding an active agent from a plasma protein in a target site in a subject includes a transducer configured to generate acoustic pressure waves and a controller coupled to the transducer. The controller is programmed to control the transducer to produce a plurality of pulsed acoustic pressure waves in the target site of the patient. The plurality of pulsed acoustic pressure waves disrupt a plasma protein binding between the active agent and the plasma protein within the target site. The disruption of the plasma protein binding causes an increase in an amount of unbound active agent in the target site.

Non-Invasive Convergent Heating Treatment
20210401288 · 2021-12-30 · ·

The invention relates to medical therapy of detrimental lesions. A system treats with non-invasive arrays of non-ionizing energy-radiation sources. The external sources focus energy dose distribution to a selected volume in a body. Energy output is directed towards a pathologic location and quenched around other sites or healthy tissue. Beam aiming is done without source movement. Targeted, volumetrically discrete energy deposition can beneficially manipulate lesions within the body. The purpose of the focused and enhanced energy deposition is to repair or disable pathologic physiology or structures, nerve pathways, extracellular fluid, and misfolded proteins. Locally augmented energy is used to enhance immunity, release pharmaceutical compounds from energy-sensitive vesicles and reconfigure or eliminate misfolded proteins and their aggregates. Targeted tissue may have enhanced sensitivity to received energy via a non-ionizing-radiation, treatment-localizing agent. This system optimizes delivery of non-ionizing, non-ablating electromagnetic or mechanical energy, degrading or repairing an abnormality upon interaction with it.

METHODS AND SYSTEMS FOR MODIFYING ELECTRICAL CURRENTS IN NEURONAL CIRCUITS

A system comprises an ultrasound subsystem and a magnetic resonance imaging (MRI) subsystem. The ultrasound subsystem applies pulses of focused ultrasound having one or more parameters to an identified location in a subject that is to receive treatment.

The MRI subsystem acquires functional image data corresponding to the identified location concurrently with the applied pulses of focused ultrasound. The MRI subsystem obtains a reconstructed series of functional images of the subject using the functional image data. The functional images are indicative of a first region within the identified location in which neuronal activity has been modified by the applied pulses. The system is configured to adjust one or more parameters of the MRgFUS treatment plan using the reconstructed series of functional images.
