Abstract:
A method and apparatus for treating patients suffering from obesity or eating disorders by applying a predetermined stimulating signal to the patient's vagus nerve appropriate to alleviate the condition and by applying a neural conduction block to the vagus nerve at a blocking site with the neural conduction block selected to at least partially block nerve impulses on the vagus nerve at the blocking site.
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.
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.
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.
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.
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.
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. The implant has multiple fibers braided along a length of the implant.
