For intraluminal ultrasound probes, the transducer is divided into multiple segments. The segments are connected in a way that allows them to slide relative to each other. This sliding arrangement allows for the transducer to be used in two different apertures at different times while in the patient. One aperture is shaped for insertion of the probe through a limited space, and the other aperture forms an array with a larger elevation extent, allowing greater quality imaging along the elevation dimension.

A computing system may identify a surgical instrument for a surgical procedure in an operating room (OR). The computing system may detect a control input by a health care professional (HCP) to control the surgical instrument. The computing system may determine the HCP's access control level associated with the surgical instrument. The computing system may determine whether the HCP has an authorization to control the surgical instrument. If the computing system determines that HCP is unauthorized to control the surgical instrument based on the access control level associated with the HCP, the computing system may block the control input by the HCP. If the computing system determines that the HCP is authorized to control the surgical instrument based on the access control level associated with the HCP, the computing system may effectuate the control input by the HCP to control the surgical instrument.

A system includes ultrasound transducers configured to generate and direct ultrasound beams at a region within a portion of a subject's brain, sensors configured to measure a response from the portion of the subject's brain in response to one or more ultrasound beams, and an electronic controller in communication with the ultrasound transducers configured to generate, based on a measured response from the portion of the subject's brain in response to two or more ultrasound beams generated from two or more different angles, a model of the portion of the subject's brain, wherein the model has a higher resolution than a maximum resolution of a single ultrasound beam, and generate, based on the model of the portion of the subject's brain, stimulation parameters for the ultrasound transducers to generate and direct a stimulation ultrasound beam at the region within the portion of the subject's brain.

A tissue treatment catheter and system include a catheter shaft sized and shaped for delivery through a radial artery to a blood vessel of a patient. The catheter shaft has several lumens, including a guidewire lumen, a cable lumen, and one or more fluid lumens. A stiffening web extends from the guidewire lumen and is thicker than an outer wall of the catheter shaft. The tissue treatment catheter and system include an ultrasound transducer, a balloon surrounding the ultrasound transducer, and a single electrical cable electrically connected to the ultrasound transducer to deliver sufficient electrical energy during sonication to the transducer such that the transducer thermally induces modulation of neural fibers surrounding the blood vessel sufficient to improve a measurable physiological parameter corresponding to a diagnosed condition of the patient. Other embodiments are described and claimed.

Methods for treating and managing pain in a patient with therapeutic neuromodulation and associated systems and methods are disclosed herein. Chronic or debilitating pain can be associated, for example, with a disease or condition of the abdominal or reproductive viscera. One aspect of the present technology is directed to methods that at least partially inhibit sympathetic neural activity in nerves proximate a target blood vessel of a diseased or damaged organ of a patient experiencing pain. Targeted sympathetic nerve activity can be modulated at least along afferent pathways which can improve a measurable parameter associated with the pain of the patient The modulation can be achieved, for example, using an intravascularly positioned catheter carrying a therapeutic assembly, e.g., a therapeutic assembly configured to use electrically-induced, thermally-induced, and/or chemically-induced approaches to modulate the target sympathetic nerve.

A method of removing microvessels includes applying a burst of acoustic energy at a target location, applying a pulse of optical energy at the target location, and promoting cavitation at the target location. The burst of acoustic energy has a pressure below 5.0 MPa. The pulse of optical energy at the target location has a fluence less than 100 mJ/cm.sup.2. At least a portion of the pulse is concurrent with the burst and the optical energy has an optical area that is overlapping with an acoustic area of the acoustic energy at the target location.

Methods for treating urinary stress incontinence by non-invasively delivering energy to one or more submucosal regions of vaginal tissue to induce remodeling within the vaginal tissue are provided. In some embodiments, the energy delivery results in heating of the target tissue to a temperature that ranges from about 38° C. to about 46° C. In some embodiments, the subject methods involve cooling a mucosal epithelial layer over the vaginal tissue. In some embodiments, a reverse thermal gradient is produced as the mucosal epithelium is cooled while energy is delivered to the underlying vaginal tissue.

The invention describes a device comprising at least one emitter of P-waves and/or S-waves, preferably shear waves, more preferably axisymmetric waves, and at least one wave receiver, wherein the receiver or receivers are disposed concentrically, and the disposition of the emitters and receivers allows same to simultaneously come into direct contact with a specimen, the structure of which it is desired to characterise. Also described is a method for characterising the spatial distribution of mechanical parameters of a specimen, based on the emission of shear waves and the subsequent reception thereof.
