  • Publication number: 20140074213
    Abstract: Nerve cuff electrode including a tubular body having a longitudinal slit having electrodes disposed within the body. Wedge shape slits are formed into at least one of the interior wall and the exterior wall of the body, whereby the number and location of slits provided to facilitate the adjustment of the amount of compressive force of nerve cuff electrode about the nerve.

  • Patent number: 8612025
    Abstract: Nerve cuff electrode including a tubular body having a longitudinal slit and a flap curled over the slit. The tubular body includes a central cathode disposed between two anodes. The region opposite the slit includes a flexible region that determines the flexibility and strength of tube opening and closing. The cuff electrode having a hinge region with a non-linear effective spring constant which can be higher at low cuff openings and lower at large opening to provide an effective yet non-damaging closing force over a wide range of cuff openings. In use, the tube body can be pulled apart using attached suture loops, with one loop and flap pulled under the nerve followed by part of the tubular body. The tubular body can be closed over the nerve and the flap closed over the tube slit.

  • Patent number: 8155757
    Abstract: Nerve cuff electrodes and methods using nerve cuffs. Nerve cuff electrodes are provided which can include a tubular body having a longitudinal slit and a flap curled over the slit. The tubular body interior can have a central cathode formed of two opposed and electrically coupled plates disposed between two anodes each formed of two opposed and electrically coupled plates. The tube interior region opposite the slit can be free of electrode material, such that the flexibility of the polymeric tube significantly determines the flexibility and strength of tube opening and closing. Some cuffs include a hinge region having a non-linear effective spring constant which can be higher at low cuff openings and lower at large opening to provide an effective yet non-damaging closing force over a wide range of cuff openings. In use, the tube body can be pulled apart using attached suture loops, with one loop and flap pulled under the nerve followed by part of the tubular body.

  • Publication number: 20100268311
    Abstract: Methods and devices for implanting an electrode near a nerve covered by a tissue layer or layers. Methods can include cutting through a tissue layer covering the nerve to form at least two exposed pleural tissue layer edges. The nerve can be freed from any tissue around the nerve and the electrode placed around the nerve. The pleura edges can be drawn toward each other to cover the nerve and the edges secured together. Some methods form two tissue flaps which are pulled away from each other to expose the nerve. Other methods form a single tissue flap which extends over the nerve and is pulled back to expose the nerve. The now covered nerve is protected against movement of tissues near the now covered nerve. Such methods find one use in placing electrodes near the splanchnic nerves in the thoracic cavity, where the lung and diaphragm may contact an exposed electrode.

  • Publication number: 20100168820
    Abstract: Methods, Implantable Pulse Generators (IPGs), and systems for stimulating a sympathetic nervous system nerve including automatically increasing the maximum stimulation current intensity over time. Some IPGS increase the current stimulation current maximum upon passage of an elapsed time or occurrence of a time of day. The current stimulation current maximum is the actual stimulation current in some methods and is a ramp maximum in other methods. The patient may interact with the IPG to indicate discomfort, resulting in a decrease in the current stimulation current maximum. In some methods, after receiving too many patient indications of discomfort, stimulation is stopped by the IPG.

  • Publication number: 20070135855
    Abstract: A patient management device for portably interfacing with a plurality of implantable medical devices and method thereof is presented. Permission to interrogate one or more implantable medical devices is authenticated. Patient device data is individually exchanged through interrogation of at least one authenticated implantable medical device through short range telemetry. External device data is exchanged via communication with at least one external device through long range telemetry. At least one of the patient device and external device data is maintained contemporaneously to execution of operations to perform one or more of relay, processing, and outputting of the patient device and external device data subsequent to the interrogation of the implantable medical device.
