Devices for therapeutic nasal neuromodulation and associated methods and systems

Devices for therapeutic nasal neuromodulation and associated systems and methods are disclosed herein. A system for therapeutic neuromodulation in a nasal region configured in accordance with embodiments of the present technology can include, for example, a shaft and a therapeutic element at a distal portion of the shaft. The shaft can locate the distal portion intraluminally at a target site inferior to a patient's sphenopalatine foramen. The therapeutic element can include an energy delivery element configured to therapeutically modulate postganglionic parasympathetic nerves at microforamina of a palatine bone of the human patient for the treatment of rhinitis or other indications. In other embodiments, the therapeutic element can be configured to therapeutically modulate nerves that innervate the frontal, ethmoidal, sphenoidal, and maxillary sinuses for the treatment of chronic sinusitis.

Insertion sheath for modular disposable endoscope components

A modular endoscope system comprises an exoskeleton, a camera unit couplable to the exoskeleton, a therapeutic unit couplable to the exoskeleton, a steering unit couplable to the exoskeleton, and a control unit couplable to the exoskeleton. A method for building a modular endoscope comprises determining camera and therapeutic capabilities of the endoscope, selecting an exoskeleton for the endoscope, attaching a camera unit and therapeutic unit, if such capabilities are determined, to the selected exoskeleton to satisfy the determined capabilities, and attaching a control unit to the exoskeleton to control any camera unit and therapeutic unit attached to the exoskeleton. A method of processing modular endoscope components for performing a surgical procedure comprises identifying a patient to receive a treatment, selecting components of the endoscope to perform the treatment, treating the patient with the endoscope, and deconstructing the components of the endoscope into reusable and disposable components.

Atrial fibrillation rf treatment device and method

A radiofrequency treatment device of the present invention includes one or two radio frequency electrode holders (42) each having multiple electrodes (44) arranged to create a transmural lesion through tissue. The treatment device is placed with one holder (42) on the endocardial surface of the heart and the other optional holder placed on the epicardial surface of the heart to form a bipolar arrangement of equally spaced parallel tissue penetrating electrodes. The invention creates a transmural lesion in heart tissue to treat atrial fibrillation by blocking passage of abnormal electrical currents through the heart tissue. The devices may also be used to apply other types of energy, including cryo, ultrasound, microwave, heat, or other electrical means of providing an interruption in abnormal electrical circuits.
