  • Publication number: 20040176812
    Abstract: At least one of a plurality of gastrointestinal disorders is treated by stimulating an enteric nervous system of a patient to enhance a functional tone of the enteric nervous system. A treatment includes electrically stimulating a vagus nerve of the patient at a stimulation site proximal to at least one site of vagal innervation of a gastrointestinal organ. The electrical stimulation includes applying a stimulation signal at the stimulation site. An optional proximal electrical blocking signal is applied to the vagus nerve at a proximal blocking site proximal to the stimulation site. The proximal blocking signal is selected to at least partially block nerve impulses at the proximal blocking site.

  • Publication number: 20040172084
    Abstract: GERD is treated through a method and apparatus of stimulating the body organ to accelerate a discharge of contents from the duodenum of the patient to thereby encourage discharge of contents from the stomach of the patient across the pyloric valve and into the duodenum.

  • Publication number: 20040172088
    Abstract: At least one of a plurality of disorders of a patient associated with vagal activity innervating at least one of a plurality of organs of the patient at an innervation site are treated by positioning a neurostimulator carrier within a body lumen of the patient. An electrode disposed on the carrier is positioned at a mucosal layer of the lumen. An electrical signal is applied to the electrode to modulate vagal activity by an amount selected to treat the disorder. The signal may be a blocking or a stimulation signal.

  • Publication number: 20040172086
    Abstract: At least one of a plurality of disorders of a patient are treated where the disorders are associated with a gastrointestinal tract of a patient where the disorders are characterized at least in part by hyper-tonal vagal activity innervating at least one of a plurality of alimentary tract organs of the patient at an innervation site. The treatment includes applying a neural conduction block to a vagus nerve of the patient at a blocking site proximal to the innervation site. The neural conduction block is selected to at least partially block nerve impulses on the vagus nerve at the blocking site. A treatment apparatus has an electrically controllable neural conduction electrode adapted to be placed on a vagus nerve of a patient at a blocking site proximal to an innervation site.

  • Publication number: 20040172085
    Abstract: A treatment apparatus and method have a stimulation electrode adapted for placement on a nerve of a patient at a stimulation site and a stimulation signal generator for generating a stimulation signal at the stimulation electrode and selected to electrically stimulate a nerve to induce bi-directional propagation of nervous impulses in a stimulated nerve. The apparatus includes a blocking member for placement on the nerve at a blocking site and creating localized conditions at the blocking site that at least partially diminish transmission of nerve impulses past the blocking site.

  • Publication number: 20040167583
    Abstract: At least one of a plurality of disorders of a patient characterized at least in part by vagal activity innervating at least one of a plurality of organs of the patient is treated by a method that includes positioning a neurostimulator carrier around a body organ of the patient where the organ is innervated by at least a vagal trunk. An electrode is disposed on the carrier and positioned at the vagal trunk. An electrical signal is applied to the electrode to modulate vagal activity by an amount selected to treat the disorder. The signal may be a blocking or a stimulation signal.

  • Publication number: 20040102686
    Abstract: Vulnerable plaque is identified through a diagnostic method by identifying pathologic markers such as C-reactive proteins or pH change generated by the pathologic site. First and second detectors are advanced through a blood vessel with each of the detectors selected to detect the pathological marker. The detectors are spaced apart while seeking the marker. Differential concentration of the pathological marker as measured by the first and second detectors indicates a presence of the pathological site in proximity to at least one of the detectors.

  • Publication number: 20040077988
    Abstract: A transmyocardial implant establishes a blood flow path through a myocardium between a heart chamber and a lumen of a coronary vessel residing on an exterior of the heart. The implant includes a coronary portion sized to be received within the vessel. A myocardial portion is sized to pass through the myocardium into the heart chamber. A transition portion connects the coronary and myocardial portions for directing blood flow from the myocardial portion to the coronary portion. The coronary portion and the myocardial portion have an open construction for permitting tissue growth across a wall thickness of the coronary portion and the myocardial portion. The myocardial portion includes an agent for controlling a coagulation cascade and platelet formation.

  • Publication number: 20030216801
    Abstract: A transmyocardial implant includes a hollow rigid conduit having a vessel portion and a myocardial portion. The vessel portion is sized to be inserted into a blood vessel segment taken from a non-coronary artery or vein. The myocardial portion is sized to extend from the vessel portion and through a myocardium into a heart chamber. The conduit has open vessel and myocardial ends on respective ends of the vessel and myocardial portions to define a blood flow pathway within an interior of the conduit between the vessel and myocardial ends. The myocardial portion is formed of a conduit material sufficiently rigid to resist deformation and closure of the pathway in response to contraction of the myocardium. The vessel portion has a radial compliance approximating a radial compliance of the vessel.
