A method and device for modulating the autonomic nervous system adjacent a pericardial space to treat cardiac arrhythmia includes a treatment source arranged to supply a treatment medium, a catheter having an end sized for insertion into the pericardial space, a medium delivery assembly having a distal end arranged to be positioned by the catheter into the pericardium, with the distal end of the delivery assembly comprising a delivery tip arranged to extend away from the distal end of the catheter into the pericardial space. A connector operatively couples the delivery tip of the medium delivery assembly to the treatment source, and the delivery tip of the medium delivery assembly including a plurality of delivery points for delivering the treatment medium at a plurality of treatment areas within the pericardial space. The device performs modulation or ablation of the autonomic nervous system at selected treatment areas within the pericardium.

Method and apparatus for percutaneous epicardial ablation of cardiac ganglionated plexi without myocardial injury

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.

Neural blocking therapy

Device and method for treating cardiac disorders by modulating autonomic response

Various methods and apparatus for treating a condition associated with impaired glucose regulation in a subject comprising in one embodiment, applying a neural conduction block to a target nerve at a blocking site with the neural conduction block selected to at least partially block nerve pulses. In another embodiment, combinations of down-regulating and or up-regulating with or without pharmaceutical agents are used to treat impaired glucose regulation. In other embodiments, up-regulation or down-regulation of various nerves, such as the vagus and its branches, and the splanchnic is used to modify the production of GLP-1 and GIP, thereby controlling glucose levels. In yet further embodiments, combinations of down-regulating and or up-regulating with or without pharmaceutical agents are used to modify the production of GLP-1 and GIP, to treat impaired glucose regulation.

Methods and systems for glucose regulation

A system for designing a therapy or for treating a gastrointestinal disorder or a condition associated with excess weight in a subject comprising at least one electrode configured to be implanted within a body of the patient and placed at a vagus nerve, the electrode also configured to apply therapy to the vagus nerve upon application of a therapy cycle to the electrode; an implantable neuroregulator for placement in the body of the patient beneath the skin layer, the implantable neuroregulator being configured to generate a therapy cycle, wherein the therapy cycle comprises an on time during which an electrical signal is delivered, the electrical signal comprising: a) a set of pulses applied at a first selected frequency of about 150-10,000 Hz, wherein each pulse of the set of pulses has a pulse width of at least 0.01 milliseconds and less than the period of the first selected frequency.

Neural modulation devices and methods

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.

Nerve stimulation and blocking for treatment of gastrointestinal disorders

A method and apparatus for treating a condition associated with impaired blood pressure and/or heart rate in a subject comprising applying an electrical treatment signal, wherein the electrical treatment signal is selected to at least partially block nerve impulses, or in some embodiments, to augment nerve impulses.

Systems for regulation of blood pressure and heart rate

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 obesity. The signal may be a blocking or a stimulation signal. In some embodiments, the signal is selected to, at least in part, downregulate neural activity on the vagus nerve.
