  • Patent number: 8413662
    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.

  • Patent number: 8369952
    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 an electrode on a vagus nerve. An electrical signal is applied to the electrode to modulate vagal activity by an amount selected to treat the disorder. In some embodiments, the disorder is gastroparesis. The signal may be a blocking or a stimulation signal. In some embodiments, the signal is selected to a) at least in part, upregulate neural activity on the vagus nerve without triggering muscular contractility, and, b) increase pancreobilliary output.

  • Publication number: 20120041509
    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 around 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 selected 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. The application of the electrical signal is discontinued. The application of the signal and the discontinuing of the signal are repeated with durations of the discontinuing and the application selected to treat the disorder.

  • Publication number: 20110282411
    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.

  • Patent number: 8027718
    Abstract: A method and apparatus are disclosed for anesthetizing a region of a patient's body. The method includes identifying a target nerve which, upon activation, anesthetizes a region of a patient's body including a surgical site. The target nerve is located and an active site of a nerve blocking apparatus is placed in proximity to the nerve. The nerve blocking apparatus is activated to block neural propagation along the nerve. The activation of the nerve blocking apparatus is maintained during a surgical procedure at the surgical site.

  • Publication number: 20110174525
    Abstract: A method and an electronic assembly for attaching a component to a substrate, or printed circuit board, is recited. The printed circuit board comprises a solder-nonwettable surface and a bond pad being formed of a solder-wettable surface. The printed circuit board defines a through hole extending through the printed circuit board and the bond pad. A plate lining a first portion of the through hole in the printed circuit board is formed of a solder-wettable material. Solder paste is applied to the bond pad and into the through hole. A component including a terminal overlies the bond pad in an arrangement. Reflowing the solder paste forms a solder fillet that bonds the terminal to the bond pad. The solder fillet extends within the through hole attaching the component to the printed circuit board.

  • Publication number: 20110021968
    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: 20100229876
    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.
