摘要:
Various approaches to generating and maintaining an ultrasound focus at a target region include configuring a controller to cause transmission of treatment ultrasound pulses from a transducer having multiple transducer elements; cause the transducer to transmit focusing ultrasound pulses to the target region and generate an acoustic reflector therein; measure reflections of the focusing ultrasound pulses from the acoustic reflector; based at least in part on the measured reflections, adjust a parameter value associated with one or more transducer elements so as to maintain and/or improve the ultrasound focus at the target region.

A bolus assembly is configured to receive and be removably coupled to a transducer assembly of an ultrasound probe assembly. The bolus assembly includes a housing assembly and at least one sealing member. The housing assembly has a body having first and second ends, and a sidewall extending therebetween, the body forming a cavity defined by the first end, second end, and sidewall, the cavity being configured to receive at least one transducer of a transducer assembly, a first passage extending through the second end of the body, the sidewall including at least one opening spaced-apart from the passage; and an acoustically transparent and distensible membrane attached to an entire outer periphery of the opening. The sealing member has a through hole and is positioned within the passage. The through hole is configured to receive the shaft. The sealing member is sealingly engaged with the shaft within the passage.

The methods and apparatus disclosed herein can be used to adjust the effective lens position ("ELP") of the eye in order to correct refractive error of the eye. The methods and apparatus can be configured to apply energy to the sclera and other regions of the eye in order to adjust the effective lens positon of the eye for far vision. The sclera can be treated in order to shrink or relax the sclera, and combinations thereof in order to adjust the position of the lens of the eye in order to correct vision related to refractive error of the eye. A target location of the lens can be determined to correct the refractive error of the eye, and the energy applied in order to move the lens toward the target location.

Systems, methods and devices are provided for performing diagnostic or therapeutic transcranial procedures using a patient-specific transcranial headset. The patient-specific headset may include a patient-specific frame that is fabricated, according to volumetric image data, to conform to an anatomical curvature of a portion of a patient's head. The patient-specific frame is configured to support a plurality of transducers in pre-selected positions and orientations, which may be spatially registered to the volumetric image data. This spatial registration may be employed to control at least a portion of the transducers to focus energy at a pre-selected tissue region.

Systems and methods for informing and evaluating neuromodulation therapy are disclosed herein. A system configured in accordance with embodiments of the present technology can include, for example, a guidewire having a proximal portion, a distal portion configured to be positioned at a target site in a blood vessel of a human patient, and a sensing element positioned along the distal portion. The sensing element can be a pressure sensing element, a flow sensing element, an impedance sensing element, and/or a temperature sensing element. The system can further include a controller configured to obtain one or more measurements related to a physiological parameter of the patient via the sensing element. Based on the measurements, the controller can determine the physiological parameter and compare the parameter to a predetermined threshold. Based on the comparison, the controller and/or the operator can assess the likelihood of the patient benefitting from neuromodulation therapy.

A technology is described for multipoint tissue elastic property measurement. An example method (700) includes generating a treatment map (710) of an anatomical region that shows focal points within the anatomical region to be exposed to Focused Ultrasound (FUS) pulses; acquiring a reference MR-ARFI image (720) of the anatomical region containing the focal points using the treatment map; acquiring an active MR-ARFI image (730) for each of the focal points in the anatomical region during exposure of the focal points to the FUS pulses using the treatment map; interleaving the reference MR-ARFI image and active MR-ARFI images (740) to create a combined image of the anatomical region and the focal points; and calculating a tissue displacement measurement (750) for the focal points exposed to the simultaneous and/or rapidly interleaved FUS pulses using the combined image of the anatomical region and the focal points exposed to the simultaneous FUS pulses.

A method of treating bowel diseases includes introducing a fluid into a portion of a patients colon and applying energy thereto from an external energy source such that the fluid and the energy cooperate to treat tissue of the portion of the patients colon in contact with the fluid. Another method of treating inflammatory bowel diseases includes sealing a portion of a patients colon, introducing an electrically-conductive fluid thereto, and energizing an electrode disposed therein to treat tissue of the portion of the patients colon in contact with the electrically-conductive fluid. Another method of treating inflammatory bowel diseases includes sealing a portion of a patients colon and introducing a heated fluid at a temperature equal to or above 60 °C to treat tissue of the portion of the patients colon in contact with the heated fluid.
