  • Publication number: 20070135856
    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: 20070073354
    Abstract: A method and apparatus are disclosed for treating a variety of conditions include treating a disorder associated with neural activity near a region of a brain. In such condition, the method includes placing an electrode to create a field near said region, creating said field with parameters selected to at least partially block neural activity within said field. For treating a tissue sensation, the method includes identifying a target area of tissue to be treated and placing an electrode to create a field near the target area, and creating the field with parameters selected to at least partially block neural activity within the target area. For treating a condition associated with neural activity of a spinal cord, the method includes placing an electrode to create a field near a nerve associated with the spinal cord, and creating the field with parameters selected to at least partially block neural activity within the nerve.

  • Publication number: 20060235462
    Abstract: A patient's pharyngeal wall is treated by inserting an expander member into the airway and positioning an active portion of the expander member in opposition to portions of the pharyngeal wall to be treated. The expander member is activated to urge the wall portions outwardly to an outwardly displaced position. The expander member is then deactivated while leaving the wall portions in the outwardly placed position and the expander member is removed from said airway. A further aspect of the treatment includes stabilization of at least a portion of the pharyngeal wall after compression of portions of the wall.

  • Publication number: 20060185673
    Abstract: A method for treating a patient diagnosed with obstructive sleep apnea includes identifying a patient as having sleep apnea susceptible to a first positive airway treatment which is at a first operating pressure level in excess of that which is otherwise tolerable to the patient. The patient is treated with an airway treatment selected to alter a portion of an airway tissue of the patient. The patient is then treated with a second positive airway pressure treatment at a second pressure level, which is below the pressure threshold.

  • Publication number: 20060189840
    Abstract: A method for treating a disease of the heart such as congestive heart failure includes forming an access opening from a heart chamber into a pericardial space defined between an epicardial surface of the heart and a pericardium opposing the epicardial surface. A cardiac support member is deployed into said pericardial space through said access opening with said cardiac support member selected to engage an epicardial surface of said heart and relieve a wall tension of said heart.

  • Publication number: 20060106332
    Abstract: A method and apparatus for treating a patient's health condition by diverting pancreatic exocrine secretions include a flow diverter of material compatible with chronic residence within a small intestine of the patient. The flow diverter has a cover end and a discharge end. The flow diverter is sized to be placed within the small intestine with the discharge end placed distally from said cover end and with said flow diverter further sized so permit passage of chyme through the small intestine and past the flow diverter. The cover end is sized to cover a discharge papilla of the pancreatic duct. The diverter is adapted to divert at least a portion of pancreatic exocrine secretion from the papilla to the distal discharge end.

  • Publication number: 20050268923
    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: 20050268922
    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: 20050251255
    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: 20050131485
    Abstract: A method for treating at least one of a plurality of disorders characterized at least in part by vagal activity includes positioning an electrode at a body organ innervated by the vagus. An electrical signal is applied to the electrode to modulate vagal activity. The electrical signal is applied at a frequency in excess of 3,000 Hz for the signal to create a neural conduction block to the vagus with the neural conduction block selected to at least partially block nerve impulses on the vagus.

  • Publication number: 20050092332
    Abstract: A method and apparatus are disclosed for treating a condition of a patient's airway. The condition is attributed at least in part to a spacing of tissue from opposing surfaces in the airway. In one embodiment, the method and apparatus include placing a tissue contractor within the tissue. The contractor includes a static end and a tissue in-growth engaging end. The static end is secured to a bony structure adjacent to tissue to be contracted. The tissue in-growth engaging end is secured to the tissue and spaced from the bony structure. A spacing between the tissue engaging end and a bony end is contracted in order to place the tissue under tension.
