Abstract
The present disclosure describes intravascular systems that may be used for a variety of functions. The elements of the disclosed systems include at least one device body implanted within the vasculature. Electrodes on a lead and/or on the device body itself are used to direct electrical energy to neurological targets. These systems may additionally include one or more fluid reservoirs housing drugs or other agents to be delivered to tissue.
Claims29
A method of electrically modulating a nervous system target, comprising the steps of:
- introducing a neuromodulation implant into the vasculature of a patient, the neuromodulation implant including a device body and a pulse generator within the device body;
- positioning at least one electrode within a superior vena cava of the patient, the electrode in communication with the device body,
- chronically retaining the neuromodulation implant within the vasculature;
- and
- with the electrode in the superior vena cava, stimulating the nervous system target using the electrode.
A neuromodulation system comprising:
- a neuromodulation implant including an intravascular pulse generator;
- an anchor engageable with a wall of a superior vena cava to anchor the neuromodulation implant within the vasculature;
- and
- at least one electrode carried by the anchor, wherein engagement of the blood vessel wall by the anchor positions the electrode in contact the superior vena cava wall proximate to a nervous system target.
