  • Publication number: 20240108899
    Abstract: Neuromodulation devices and associated systems and methods are disclosed herein. Various embodiments of the present technology relate to devices, systems, and methods for delivering electrical energy to a hypoglossal nerve of a patient. According to some embodiments, the present technology includes an implantable neuromodulation device comprising an electronics package, a branched lead body, and an extension portion between the electronics package and lead body. The lead body can comprise a first arm with first conductive elements and a second arm with second conductive elements. The lead body can be configured to be positioned between a patient's genioglossus and geniohyoid muscles such that the first arm and first conductive elements are positioned proximate one of the patient's hypoglossal nerves and the second arm and second conductive elements are positioned proximate a contralateral one of the patient's hypoglossal nerves.

  • Publication number: 20210007801
    Abstract: Helical push wire electrodes are provided. The electrodes may create a continuous helical lesion. One or more electrodes may wind around a support section and create a set of helixes having fixed ends and hitches. Pushing or pulling an end of the electrode transforms the electrodes between a delivery configuration and a deployed configuration such that the set of helixes expand or contract axially. Different portions of the electrodes may be surrounded by sleeves. The sleeves may regulate how the wires transform and provide insulation. Various insulation configurations of the electrodes may provide creations of discrete lesions, efficient energy delivery and reduced power consumption.

  • Publication number: 20160228291
    Abstract: Systems and methods for accurate temperature modification of a patient, or selected regions thereof, including inducing hypothermia. The temperature modification is accomplished using an in-dwelling heat exchange catheter within which a fluid heat exchange medium circulates. A heat exchange cassette attached to the circulatory flow lines of the catheter, the heat exchange cassette being sized to engage a cavity within a control unit. A temperature measurement scheme for obtaining body core temperature is provided, including methods of obtaining and analyzing temperature data to provide feedback to the control unit for use in controlling the heating and cooling of the heat exchange medium so as to heat or cool a patient to a desired target temperature.

  • Publication number: 20140276791
    Abstract: Treatment devices with electrode contact surfaces configured for enhancing uniformity of electrical energy distribution are provided. In one embodiment, a treatment device includes a tubular electrode having a wall, a contact surface defined by the wall, and cut shapes at least partially extending through the wall. The tubular electrode is configured to transmit electrical energy to a treatment site within a body lumen via the contact surface, and the individual cut shapes are configured to draw a portion of the electrical energy toward an interior region of the contact surface. A shaft having a distal end portion operably coupled to the tubular electrode can locate the tubular electrode at the treatment site.
