  • Patent number: 8428730
    Abstract: A transvascular electrode system includes an expandable electrode-carrying anchor. The anchor is intravascularly advanced in a compressed position to a first site in a blood vessel. A first portion of the anchor expands to position an electrode against the vessel wall, while a second portion remains is compressed. Mapping is performed by delivering stimulation energy from the electrode and measuring the response (e.g. blood pressure, heart rate, and/or related parameters). The first portion is at least partially collapsed and the electrode system is moved to a second site. The first portion is expanded to position the electrode into against the vessel wall, while the second portion remains compressed. Additional mapping is performed. The process is repeated until the anchor electrode position is optimized, at which point the second portion of the anchor is expanded to chronically retain the electrode in the vessel.

  • Patent number: 8369954
    Abstract: Methods and systems are disclosed for stimulating contents of the carotid sheath using an intravascular pulse generator and lead. The lead carries an energy delivery device such as an electrode, which is anchor within the portion of the internal jugular vein that is disposed within the carotid sheath. The energy delivery device is energized to transvenously direct energy to target contents of the carotid sheath external to the internal jugular vein. Such target contents may include nervous system elements associated with the carotid sinus baroreceptors, the carotid sinus nerve and associated nerve branches, and or the vagus nerve and associated nerve branches. The system may be used to control blood pressure and/or to lower heart rate and may be suitable for treatment of hypertension, heart failure, or other conditions.

  • Publication number: 20120059431
    Abstract: The present disclosure describes intravascular systems that may be used for a variety of functions. The elements of the disclosed systems include at least one device body implanted within the vasculature. Electrodes on a lead and/or on the device body itself are used to direct electrical energy to neurological targets. These systems may additionally include one or more fluid reservoirs housing drugs or other agents to be delivered to tissue.

  • Publication number: 20110130709
    Abstract: Methods of iontophoretically delivering therapeutic agents to diseased tissue, such as for tumor therapy, are disclosed. In one embodiment, the distal end of an endoscopic device is transorally introducing into the gastro-intestinal tract. A delivery element is advanced from the endoscopic device through a wall of the gastro-intestinal tract and into an adjacent pancreas. A therapeutic agent is delivered from the delivery element into the pancreas, an electric field is generated to drive the emitted therapeutic agent into surrounding tissue of the pancreas, causing the emitted agent to penetrate the surrounding tissue.

  • Publication number: 20090012546
    Abstract: A device for treating GERD includes a pair of sections. Each section includes a proximal end portion with an arcuate interior opening, a distal end portion with an arcuate interior opening, an exterior plate portion, and a tapered body portion extending from the proximal end portion to the distal end portion. The pair of sections surround the esophagus at the gastro-esophageal junction thereof and to be secured together to form a tubular housing with a proximal orifice, a distal orifice smaller than the proximal orifice, and a plate adjacent the distal orifice. A portion of the housing adjacent the distal orifice is configured to elastically deform to constrict the esophagus and serve the function of the LES when a force is applied to the plate by the fundus. The proximal end portion of each mating section includes a flange portion configured to be attached to a body cavity wall.

  • Publication number: 20090012542
    Abstract: Satiation devices for controlling obesity and methods of implanting same are configured to create a small satiation pouch in the proximal portion of the stomach with a narrow passage leading into the lower portion of the stomach. The small satiation pouch is configured to collect a small amount of masticated food from the esophagus and the narrow passage delays emptying of the food from the satiation pouch into the larger part of the stomach, thereby causing a feeling of fullness.
