  • Publication number: 20040172054
    Abstract: A pharyngeal airway having a pharyngeal wall of a patient at least partially surrounding and defining the airway is treated by selecting an implant dimensioned so as to be implanted at or beneath a mucosal layer of the pharyngeal wall and extending transverse to said wall. The implant has mechanical characteristics for the implant, at least in combination with a fibrotic tissue response induced by the implant, to stiffen said pharyngeal wall to resist radial collapse. The implant is implanted into the pharyngeal wall transverse to a longitudinal axis of the airway.

  • 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.

  • Patent number: 6742524
    Abstract: A patient's upper airway condition such as snoring and sleep apnea is treated by selecting a particulate material selected for limited migration within tissue and for encouraging a fibrotic response of tissue to the material. A bolus of the particulate material is injected into the tissue area to structurally stiffen the tissue.

  • 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: 20040073272
    Abstract: The present disclosure relates to methods and apparatuses for treating snoring by implanting a stimulating electrode into a patient. The electrode is placed in stimulating contact with an airway passage-controlling muscle of the patient. The electrode is energized to contract the muscle and alter the airway passage.

  • Patent number: 6699275
    Abstract: An intraluminal stent comprises a reticulated tube having an un-deployed diameter and expandable to an enlarged diameter. When the tube is at the un-deployed diameter, the tube has cell-defining portions with opposing surfaces defining an open cell bounded by the cell-defining portions.

  • Publication number: 20040020498
    Abstract: A method and apparatus for treating snoring of a patient includes providing an implant for altering a dynamic response of a soft palate of the patient to airflow past the soft palate. The implant is embedded in the soft palate to alter the dynamic response. For example, the implant has a mass, stiffness or dampening sufficient to alter the dynamic response following the implantation without substantially impairing a function of the soft palate to close a nasal passage of the patient during swallowing.

  • Publication number: 20030199865
    Abstract: A method for treating a body lumen having a pathologic occlusion at least partially occluding a flow of body fluid in the lumen includes obstructing the lumen with an artificial occlusion distal to the pathologic occlusion. The pathologic occlusion is ablated in a process which may create a plurality of emboli of the pathologic occlusion on a proximal side of the artificial occlusion. The emboli are removed from the lumen and, subsequently, the artificial occlusion is removed.

  • Publication number: 20030199917
    Abstract: A method for treating a body lumen having a natural occlusion at least partially occluding a flow of body fluid in the lumen includes obstructing the lumen with an artificial occlusion distal to the natural occlusion. The natural occlusion is ablated in a process which may create a plurality of emboli of the natural occlusion on a proximal side of the artificial occlusion. The emboli are removed from the lumen and, subsequently, the artificial occlusion is removed.

  • Publication number: 20030196669
    Abstract: An apparatus for use in treating snoring of a patient suffering from snoring includes an implant of bio-compatible material sized to be embedded within the soft palate. The implant is disposed within a bore of a distal tip of a needle for penetration into the soft palate. The bore is sized to receive a rod from a proximal end of the needle with the rod opposing the implant to eject the implant from the distal tip upon relative sliding movement of said needle and said rod. The needle at the distal tip is perforated for fluid to flow through a wall of the needle into engagement with the implant. The implant is selected to altering a dynamic response of the soft palate to airflow past the soft palate.
