  • Publication number: 20130190835
    Abstract: According to various method embodiments, a person is indicated for a therapy to treat a cardiovascular disease, and the therapy is delivered to the person to treat the cardiovascular disease. Delivering the therapy includes delivering a vagal stimulation therapy (VST) to a vagus nerve of the person at a therapeutically-effective intensity for the cardiovascular disease that is below an upper boundary at which upper boundary the VST would lower an intrinsic heart rate during the VST.

  • Patent number: 8457734
    Abstract: Various aspects provide an implantable device. In various embodiments, the device comprises at least one port, where each port is adapted to connect a lead with an electrode to the device. The device further includes a stimulation platform, including a sensing circuit connected to the at least one port to sense an intrinsic cardiac signal and a stimulation circuit connected to the at least one port via a stimulation channel to deliver a stimulation signal through the stimulation channel to the electrode. The stimulation circuit is adapted to deliver stimulation signals through the stimulation channel for both neural stimulation therapy and CRM therapy. The sensing and stimulation circuits are adapted to perform CRM functions. The device further includes a controller connected to the sensing circuit and the stimulation circuit to control the neural stimulation therapy and the CRM therapy. Other aspects and embodiments are provided herein.

  • Patent number: 8386045
    Abstract: Various system embodiments comprise an implantable lead, an implantable housing, a neural stimulation circuit in the housing, and a controller in the housing and connected to the neural stimulation circuit. The lead has a proximal end and a distal end. The distal end is adapted to deliver neural stimulation pulses to the ventral nerve root and the dorsal nerve root. The proximal end of the lead is adapted to connect to the housing. The neural stimulation circuit is adapted to generate neural stimulation pulses to stimulate the ventral nerve root or the dorsal nerve root using the implantable lead. The controller is adapted to control the neural stimulation circuit to deliver a neural stimulation treatment.

  • Publication number: 20100228310
    Abstract: According to various embodiments of a method for modulating autonomic neural activity in a body having a spinal cord, a subclavian vein and thoracic lymphatic vessels that include a thoracic duct and a right lymphatic duct, at least one programmed therapy is implemented using an implanted medical device to modulate autonomic neural activity. Implementing the therapy includes increasing or decreasing sympathetic activity in sympathetic nerves branching from a first region of the spinal cord using a first electrode in the thoracic duct, and further includes increasing or decreasing parasympathetic activity in parasympathetic nerves adjacent to the desired thoracic lymphatic vessel or sympathetic activity in sympathetic nerves branching from a second region of the spinal cord using a second electrode in the desired thoracic lymphatic vessel.

  • Publication number: 20090270960
    Abstract: Various system embodiments comprise a lead having a distal end and a proximal end. The distal end includes a plurality of electrodes. The lead is configured to be fed into a dorsal epidural space of a human to a desired region of a spinal column and to be fed laterally to at least partially encircle a spinal cord in the desired region to place at least one stimulation electrode in position to stimulate a dorsal nerve root and at least another stimulation electrode in position to stimulate a ventral nerve root. The desired region may include cervical vertebrae, thoracic vertebrae, or lumbar vertebrae. Some embodiments stimulate the spinal cord in the T1-T5 region.
