  • Publication number: 20250213164
    Abstract: A system for use with an electrophysiological procedure includes a catheter assembly including a plurality of coaxially disposed catheter elements, the plurality of catheter elements movable with respect to each other along the longitudinal axis. The system further includes a controller configured to generate a first position of the first catheter element based on the first electrical signal and generate a second position of the second catheter element based on the second electrical signal and, in response to a detected longitudinal movement of the second catheter element along the longitudinal axis with respect to the first catheter element, apply a historical correction to the first and second positions based on a previously determined first and second position vector to obtain an initially corrected first and second positions. The control further generates an anatomical map of the electrophysiological procedure with a visualization of the catheter assembly including the longitudinal adjustment.

  • Publication number: 20240216076
    Abstract: A system for use with an electrophysiological procedure is disclosed. The system includes an elongated catheter assembly having a tracking sensor and a controller. The controller is configured to track catheter assembly positions within the organ based on a plurality of electrical signals from the tracking sensor, determine a first catheter assembly position based on a first electrical and determine a second catheter assembly position based on a second electrical signal, constrain the second position with the first position, and generate an anatomical map of an organ of the electrophysiological procedure with a visualization of the catheter assembly having the second position constrained with the first position.

  • Patent number: 11259744
    Abstract: Apparatus for providing transcutaneous electrical nerve stimulation (TENS) therapy to a user, the apparatus comprising: a housing; an application unit for providing mechanical coupling between the housing and the user's body; a stimulation unit for electrically stimulating at least one nerve of the user; a sensing unit for sensing the user's body movement and body orientation; and a reporting unit for providing the user with feedback based on the user's sensed body movement and body orientation.

  • Patent number: 10130810
    Abstract: Apparatus for transcutaneous electrical nerve stimulation in a user, the apparatus comprising: a housing; stimulation means carried by the housing for electrically stimulating at least one nerve; a pair of electrodes releasably mounted to the housing and connectable to the stimulation means for electrical stimulation of the at least one nerve; monitoring means for monitoring user gesture, electrode-skin contact integrity and transient motion; analysis means for analyzing the output of the monitoring means for determining user gesture, electrode-skin contact integrity and transient motion; and control means for controlling the output of the stimulation means in response to the determined user gesture, electrode-skin contact integrity and transient motion.
