Abstract
The present disclosure relates to devices, systems and methods for positioning a neuromodulation device at a treatment site and evaluating the effects of therapeutic energy delivery applied to tissue in a patient. Before, during and/or after therapeutic energy delivery, a system can monitor parameters or values relevant to efficacious neuromodulation by emitting and detecting diagnostic energy at the treatment site. Feedback provided to an operator is based on the monitored values and relates to a relative position of the treatment device at the treatment site, as well as assessment of the likelihood that a completed treatment was technically successful.
Claims21
A system, comprising:
- an elongated shaft including a distal portion configured to be positioned in a lumen of a patient;
- and
- a treatment assembly coupled to the elongated shaft, the treatment assembly including:
- a neuromodulation element configured to deliver a therapeutic energy using a first energy modality, wherein the therapeutic energy includes ultrasound energy;
- and
- one or more diagnostic elements configured to:
- emit diagnostic energy, using a second energy modality that is different than the first energy modality, toward tissue of the lumen, wherein the diagnostic energy includes electromagnetic energy, and
- detect return energy, wherein the return energy includes electromagnetic energy;
- and
- a controller including processing circuitry, the controller configured to:
- determine, based on the return energy, a relative distance of at least a portion of the treatment assembly to a target nerve when the treatment assembly is positioned within the lumen, and
- cause the treatment assembly to deliver the therapeutic energy based on the relative distance.
A system, comprising:
- an elongated shaft including a distal portion configured to be positioned in a lumen of a patient;
- a treatment assembly coupled to the elongated shaft, the treatment assembly including a neuromodulation element configured to deliver a therapeutic energy using a first energy modality, wherein the therapeutic energy includes ultrasound energy;
- an emitter configured to emit diagnostic energy, using a second energy modality that is different than the first energy modality, toward tissue of the lumen, wherein the diagnostic energy includes electromagnetic energy;
- a detector configured to detect, using a detection modality different from the first energy modality, a return energy associated with the diagnostic energy;
- and
- a controller including processing circuitry, the controller configured to:
- determine, based on the detected return energy, a proximity of at least a portion of the treatment assembly to a target nerve when the treatment assembly is positioned within the lumen, and
- based on the proximity, cause the treatment assembly to deliver the therapeutic energy.
A system, comprising:
- an elongated shaft including a distal portion configured to be positioned in a lumen of a patient;
- a treatment assembly coupled to the elongated shaft, the treatment assembly comprising:
- a neuromodulation element configured to deliver therapeutic ultrasound energy;
- and
- an expandable element configured to expand to a deployed state to position the neuromodulation element in the lumen;
- one or more diagnostic elements configured to emit diagnostic electromagnetic energy and detect return electromagnetic energy;
- and
- a controller including processing circuitry, the controller configured to:
- determine, based on the detected return electromagnetic energy, a proximity of at least a portion of the treatment assembly to a target nerve when the treatment assembly is positioned within the lumen, and
- based on the proximity, cause the treatment assembly to deliver the therapeutic ultrasound energy.
