A neuromodulation system including a catheter has a balloon along its distal end. An ultrasound transducer positioned within an interior of the balloon can be selectively activated to emit acoustic energy radially outwardly, targeting nerve tissue and other portions of the subject anatomy. Targeted nerve tissue can be heated by the application of ultrasonic energy to neuromodulate the tissue. The system may be delivered over a guidewire. A catheter enhances fluid delivery to a distal end of the catheter while reducing an overall diameter of the catheter. The catheter comprises a guidewire lumen that is eccentric relative to a center axis of the catheter.

Ultrasound-based neuromodulation system

A neuromodulation system including a catheter having a balloon along its distal end is disclosed in several embodiments. An ultrasound transducer positioned within an interior of the balloon can be selectively activated to emit acoustic energy radially outwardly in order to target nerve tissue and other portions of the subject anatomy. In some embodiments, the system is configured to be delivered over a guidewire.

According to some embodiments, a method of depositing at least one electrode on a base member of an ultrasound transducer comprises at least partially etching a surface of the base member using a first etching agent, catalyzing the surface of the base member using a first catalyst, plating copper on the surface of the base member using an electroless plating process, inspecting the copper plated on the surface of the base member, at least partially etching a surface of the copper-plated surface using a second etching agent, catalyzing the copper-plated surface using a second catalyst, plating nickel on the copper-plated surface using an electroless plating process and depositing at least one layer of gold on the nickel-plated surface.

A method and system for acquiring data in an ultrasound system are provided. A transducer is operatively connected to a transmit beamformer and a receive beamformer. The receive beamformer is configured to obtain a first value associated with a fundamental frequency interleaved with a second value associated with a harmonic frequency. A first transmit signal is transmitted at a first frequency. A first echo signal is received in response to the first transmit signal. At least the first value associated with the first frequency is obtained from the first echo signal. An interleaved second transmit signal is transmitted at the first frequency or a second frequency. A second echo signal is received in response to the second transmit signal. At least the second value associated with a third frequency is obtained from the second echo signal. Images are generated and displayed based on the at least one first value and the at least one second value.

Method and apparatus for frequency control of an ultrasound system

A method and apparatus for quantifying and displaying ultrasound signals in an ultrasonic system are provided. A first signal value for each of at least one spatial location in a region of interest is acquired at a first time, and the signal values are summed to obtain a first surface integral value. A second signal value for each of said at least one spatial location in said region of interest is acquired at a second time, and the second signal values are summed to obtain a second surface integral value. The first surface integral value is summed with the second surface integral value to obtain a time based integral. The time based integral is displayed. Other quantities based on any of various ultrasound parameters, such as Doppler energy, Doppler velocity and B-mode intensity, are calculated and displayed as quantities or as waveforms as a function of time. Furthermore, various comparisons of quantities and waveforms are provided. Image plane data or other ultrasound data are used in the calculations. Finally, a histogram data structure is provided to aid calculation of the various quantities.

Method and apparatus for ultrasound image quantification

A system and method for tracking the position and orientation of a movable medical imaging device using a first and second sensor disposed on the device. The second sensor is of a different type than the first sensor and measures a P/O parameter different from that of the first sensor. The system and method also include techniques for recalibrating sensors using measurements from other sensors and improving the measurements made by some sensors using measurements from other sensors. The system and method also include measuring the position of a medical implement relative to a movable medical imaging device by providing a first and second subsystem on the medical implement and a third and fourth subsystem on the movable medical imaging device. The first subsystem has a sensor of a first type and the second subsystem has a sensor of a second type different from the sensor of the first type. The third subsystem has a sensor of a third type and the fourth subsystem has a sensor of a fourth type different from the third type.

Method and apparatus for setting the integration interval for time

An ultrasonic imaging device for imaging the middle and inner ear is here described. It includes a thin, flattened shaft, a deformable support structure, a mounting surface, and an ultrasonic imaging array. Imaging is effected by the introduction of an acoustically conductive fluid into the middle ear space. Access to the tympanum through the external auditory canal and adjacent to the probe shaft for the purpose of injecting fluid into the middle ear space both before and during the exam is permitted by the flattened probe shaft. The deformable probe shaft may be bent or angulated to best fit a particular patients ear thus permitting optimal access for imaging through the tympanum and around the manubrium of the malleus attached down the midline of the tympanum. High resolution imaging of all structures within the middle and inner ear is achievable.
