Abstract: Methods of treating tumors by administering compounds to a patient are provided. Compounds such as drugs, may be administered to the patient orally, by injection, intravenously, or topically, which then accumulate preferentially as compounds such as protoporphyrin IX (PpIX) in tumor cells. After such accumulation, compounds such as PpIX are then activated in various aspects to treat tumors cells, thereby treating cancer. Cancers such as glioblastoma may be treated.

Abstract: An ultrasound phased array transducer is disclosed that achieves suppression of grating lobes through the incorporation of a coupling layer, where the coupling layer is positioned adjacent to the phased array transducer such that an ultrasound beam propagates through the coupling layer prior to encountering a propagation medium. The phased-array elements may be provided such that one or both of the array pitch and a lateral extent of each ultrasound transducer element is larger than half of the ultrasound wavelength in the propagation medium. Grating lobes within the coupling layer and the propagation medium may be reduced or suppressed by selecting a coupling material having a speed of sound that exceeds that of the propagation medium. The coupling layer may have a thickness sufficient for the generation of a wavefront, and the coupling layer may be formed from a viscous or viscoelastic material.

Abstract: A surgical instrument includes a body, a shaft assembly, and an end effector. The shaft assembly extends distally from the body. The end effector is located at a distal end portion of the shaft assembly. The end effector includes an active feature configured to operate on tissue. The body includes a drive feature operable to drive the active feature of the end effector. The body is removably coupled with the shaft assembly in a connected state and separated from the shaft assembly in a disconnected state. The body includes a drive feature configured to drive operation of the active feature of the effector. The drive feature includes at least one of an ultrasonic drive feature or a mechanical drive feature. A proximal end portion of the shaft assembly is configured to be removed from the body to separate the at least one activation feature from the drive feature.

Abstract: Improved acoustic neurostimulation is provided using two or more acoustic transducers generating an acoustic interference pattern. In a first operating mode the transducers are driven at the same frequency. In a second operating mode the transducers are driven at different frequencies. The acoustic interference pattern is varied electronically by control of the driving frequencies. In addition, a method for neurostimulation excites two confocal ultrasound transducers using an excitation waveform signal that has a time-varying frequency within range containing a resonance frequency of the two transducers, thereby increasing resolution and allowing electronic scanning.

Abstract: A method and device for skin or deeper organ treatment uses an applicator that includes a transducer for producing beams of pressure waves and a coupler for coupling the pressure waves to the skin or deeper organ. The pressure waves in the skin and deeper propagate in directions generally extending at small angles relative to the skin surface

Abstract: A system and method can be used to denervate at least a portion of a bronchial tree. An energy emitter of an instrument is percutaneously delivered to a treatment site and outputs energy to damage nerve tissue of the bronchial tree. The denervation procedure can be performed without damaging non-targeted tissue. Minimally invasive methods can be used to open airways to improve lung function in subjects with COPD, asthma, or the like. Different sections of the bronchial tree can be denervated while leaving airways intact to reduce recovery times.

Abstract: Ultrasound imaging and therapy with the same array of capacitive micromachined ultrasonic transducers is provided. The electronics includes a per-pixel switch for each transducer element. The switches provide an imaging mode driven completely by on-chip electronics and a therapy mode where off-chip pulsers provide relatively high voltages to the transducer elements.
