  • Patent number: 11565080
    Abstract: Disclosed herein is a catheter tip sized and configured to fit onto a distal end of a catheter shaft, the catheter shaft having a shaft outer diameter. The catheter tip includes a base, a tip having an arcuate shape, an outer surface extending from the base to the tip along a longitudinal axis, the outer surface having a diameter at the base that is substantially equal to the shaft outer diameter, and an inner surface extending from the base, wherein the inner surface defines a first region having a first diameter and a second region having a second diameter, wherein the second diameter is less than the first diameter, and wherein the second region is distal of the first region and configured to receive at least one component extending beyond the distal end of the catheter shaft.

  • Patent number: 11426235
    Abstract: An electrode loop assembly for a catheter includes a form wire shaped as a loop, an activation wire coupled to the form wire, and a support tube defining a lumen and enclosing the form wire and the activation wire therein. The activation wire is operable to selectively vary a diameter of the loop, and is routed along a radial inner side of the form wire. The support tube extends along a longitudinal axis from a proximal end to a distal end, and has an oblong cross-section having a major axis. The support tube is twisted about the longitudinal axis such that an orientation of the major axis changes along a length of the support tube.

  • Patent number: 10898686
    Abstract: Actuators for steerable medical devices are disclosed that not only deflect or steer a portion of a medical device (e.g., a distal portion of a catheter shaft), but also include mechanisms for actively returning the deflected portion of the medical device to an initial configuration (e.g., straight or substantially straight). These active return-to-straight mechanisms may return a catheter shaft from a deflected configuration to a substantially straight configuration throughout a medical procedure, may employ one or more tension members extending along the catheter shaft, and may comprise a gross return actuator and a fine return actuator. For example, the gross return actuator may be configured to partially reverse the deflection of the distal portion of the catheter; and the fine return actuator may be configured to continue reversing the deflection. The gross return actuator may automatically trigger or actuate (mechanically or electromechanically) the fine return actuator.

  • Patent number: 10413704
    Abstract: The present disclosure provides a medical device (10) comprising a friction member (30, 48) configured to assist in controlling and/or limiting unintentional and/or undesirable movement between two releasably secured components (18, 28) of the medical device. The releasably secured components may be part of a resistance assembly for holding a medical device actuator (20) in a particular position and/or to improve the ease of which the activator moves into one position versus another position.

  • Patent number: 9440063
    Abstract: An electrode assembly for neuro-cranial stimulation includes an electrode, a conductive gel, and an adapter including an interior compartment for positioning the electrode relative to the adapter and for receiving and retaining the conductive gel. The conductive gel contacts the electrode along an electrode-gel interface. An orifice at one end of the interior compartment and adjacent to a positioning surface of the adapter for positioning the electrode assembly against a skin surface of a user enables the conductive gel is able to contact the skin surface of the user to define a gel-skin interface, such that a minimum distance between the electrode-gel interface and the gel-skin interface is maintained between 0.25 cm and 1.3 cm. An electrode assembly mounting apparatus is provided for adjustably positioning a plurality of electrode assemblies against target positions on the cranium.

  • Publication number: 20150287092
    Abstract: A user account may have various attributes which define the user personally. The attributes may be applied to product information of other users so the favorite products of various users with similar attributes can be shared automatically. One example method of operation may include identifying user profile attributes of a first user profile, comparing the user profile attributes to other user profile attributes of other user profiles to identify flagged products of interest by each of the other user profiles, comparing the flagged products associated with the other user profile attributes to identify a minimum relevancy threshold between the user profile attributes and the other user profile attributes, and updating a first data feed of the first user profile with the flagged products that are associated with other user profiles attributes which are above the minimum relevancy threshold as compared to a weighted sum of the user profile attributes of the first user profile.

  • Patent number: 8965514
    Abstract: A method includes coupling electrodes to a patient's head and identifying whether any of the electrodes form a functional set, such that a desired therapeutic effect is achieved when the two or more electrodes deliver a total amount of current to the patient regardless of what portion of the total amount of current each respective electrode carries. One or more constant current sources are provided, each having a supply and return terminal, which supply and return equal amounts of current at any given time. The constant current source(s) are coupled to the electrodes in such a manner that each supply terminal and each return terminal is coupled to no more than the electrodes of a single one of the functional sets, if any, or to a single one of the electrodes not included in one of the functional sets.
