Abstract:
A method of treating a patient having a blood pressure comprises delivering neuromodulation therapy to sustain or increase the blood pressure. The neuromodulation therapy includes placing a sympathetic therapy electrode in a posterior portion of a blood vessel and stimulating at least one extravascular cardiac sympathetic nerve fiber using said electrode.
Abstract:
A method of treating autonomic imbalance in a patient includes energizing a first therapeutic element disposed to deliver therapy to a parasympathetic nerve fiber (e.g. vagus nerve), and energizing a second therapeutic element to deliver therapy to a sympathetic cardiac nerve fiber. At least one of the therapeutic elements is disposed in the vasculature superior to the heart. The therapy decreases the patient's heart rate and elevates or maintains the blood pressure of the patient.
Abstract:
The present application describes a retention device for anchoring a medical device within the vasculature. The device may include expandable member coupled to an intravascular medical device and proportioned for receipt within a vessel. At least a portion of the expandable member is expandable to radially engage a vessel wall and to thereby retain the medical device within the vessel. The system is suitable for a variety of intravascular devices, including but not limited to ICD's, pacemakers, and intravascular drug delivery systems.
