  • Publication number: 20190022377
    Abstract: Disclosed is a system including an electrode and a stylet configured to steer the electrode towards its intended position during implantation, and a method for such system's use. An electrode is provided having regions with varied flexibility. A stylet having bends that are indexed to specific regions of flexibility of the electrode may be inserted into the electrode, and upon minimal radial and/or longitudinal movement of the stylet within the electrode, will cause the magnitude of the angle to which the lead is bent to either increase or decrease so as to aid the operator in placement of the electrode.

  • Patent number: 9867992
    Abstract: A watchdog unit receives stay-alive signals from a programming device during programming of an implantable medical device. The watchdog unit maintains a watchdog timer, and resets the timer upon receipt of each stay-alive signal. If the watchdog timer expires, the watchdog unit changes a mode of operation of the implantable device, e.g., places the implantable medical device into a known, safe state. For example, the watchdog unit may cause the implantable medical device to suspend delivery of therapy, perform a power-on reset, and/or recall a known, safe, therapy delivery program.

  • Patent number: 9259570
    Abstract: Disclosed is an electrode, such as an SCS paddle electrode, having a lead attached thereto along an interior portion of the electrode. The lead and electrode are configured such that the lead may be positioned generally coplanar with a top surface of the electrode, and may likewise be erected from such coplanar orientation up and away from the top surface of the electrode. Thus, the lead can maintain the typical configuration of emerging from the back end of the electrode, but because at least portions of the lead are not permanently bonded into the electrode paddle, the lead (when desired) can be pulled upward, with or without surrounding strain relief material, to emerge from the top surface of the paddle at an angle or curve to such top surface. This allows the base of the paddle to engage a bony opening, such as when the electrode is inserted into a patient's spine, skull, plane of fascia, etc.

  • Patent number: 8712545
    Abstract: A paddle lead includes a plurality of electrodes configured in at least three rows of three electrodes with the second, intermediate row operable to provide anode guarding. The paddle lead further includes a plurality of grooves disposed on a surface opposite the electrodes to facilitate the insertion of the paddle lead within a patient by inhibiting the veering of the paddle lead to one side or the other of the dorsal column as the paddle lead is advanced along the dorsal column midline during implantation.

  • Patent number: 8447408
    Abstract: A user, such as a clinician or the patient, uses a control device to manipulate at least one neurostimulation parameter. A mapping system uses a calibrated map to map the directional output of the control device to values of at least one stimulation parameter to allow the user to intuitively control the value of the parameter. In some embodiments, where a stimulation device is used to deliver spinal cord stimulation (SCS) therapy for example, the user manipulates a parameter to effect the location and/or strength of paresthesia experienced by the patient. In exemplary embodiments, the parameter values are combinations of electrodes, and the mapping system selects electrode combinations based on the output of the control device such that a direction of movement of paresthesia experienced by the patient corresponds to a direction of manipulation of a directional controller of the control device. The mapping system may calibrate the map based on patient paresthesia information received from a user.

  • Patent number: 8386054
    Abstract: Disclosed is a modular system for providing electrical stimulation, in which a first modular electrode section has a contoured back end configured to engage a contoured front end of another electrode section or a tool that may be used to place the first modular electrode section in the patient's body. The contours of the modular electrode section allow the two components to engage with one another so as to prevent their separation in the horizontal plane, and a lead extending from the first modular electrode is configured to engage keels on the top surface of the second electrode portion or tool, with such keels providing a snap-type attachment between the lead and the second electrode portion or tool, such that the two components may be joined together but easily separated from one another through the intentional separation of the lead from the keels on the second electrode portion or tool.

  • Patent number: 8311643
    Abstract: Disclosed is an implantable anchor for anchoring a catheter, including (by way of non-limiting example) an implantable lead, such as may be used for spinal cord stimulation, to the body of a patient, along with a method for its use. The anchor comprises an elongate body have a central lumen extending through the body from its proximal end to its distal end, which central lumen is configured to snugly receive the catheter body. In addition to the central lumen, a second lumen is provided in the proximal end of the anchor and is configured to receive an injector so that adhesive may be injected into the anchor surrounding at least a portion of the catheter body. In doing so, the anchor may be fixed to the catheter body, such that when the anchor is sutured in place within the patient's body, migration of the catheter may be avoided.
