Abstract: A method of treating a neurological disorder comprises introducing an electrical stimulation lead within a patient's head, locating the stimulation lead within the 4th ventricle of the patient's head, and placing the stimulation lead adjacent the fastigium nucleus of the patient's brain. The method may further comprise stimulating the fastigium nucleus with the stimulation lead to treat the neurological disorder, for example, by increasing the flow of blood within the patient's brain.

Abstract: A method of treating a disorder in a patient is provided. The method comprises delivering a stimulation lead within a blood vessel, intralumenally puncturing a wall of the blood vessel to create an exit point, and then introducing the stimulation lead through the exit point into direct contact with tissue the stimulation of which treats the disorder. Optionally, the method comprises implanting a source of stimulation within the patient's body, and then electrically coupling the proximal end of the stimulation lead to the implanted stimulation source. Using the stimulation lead, the tissue can then be stimulated in order to treat the disorder.

Abstract: Apparatus and methods are disclosed for vein and arterial-venous fistulas stenosis and occlusion therapies, including enhancing permeability of the vessel wall using ultrasound energy and delivering a therapeutic agent into the vessel wall. Ultrasound energy may be delivered at frequencies less than 10 MHz and power less than 20 watts using transcutaneous techniques and endovascular methods. Therapeutic agents may be delivered to the treatment area via intravenous and endovascular methods. In some embodiments, ultrasound energy and therapeutic agent application may be combined with angioplasty techniques and with blood flow protection devices. In some other embodiments, a therapeutic agent may be removed from the body after exposure to the vessel wall to minimize a systemic effect of the therapeutic drug.

Abstract: A medical lead and method of treating a patient are provided. The medical lead comprises an electrically insulative tubular membrane, a resilient spring element associated with the insulative membrane, and at least one electrode associated with the insulative membrane. The medical lead is configured to be collapsed into a compact form for percutaneous delivery into the patient, thereby obviating the need to perform an invasive surgical procedure on the patient. The body formed by these elements, when expanded, can be sized to fit within the epidural space of a patient. The patient can be treated by placing the medical lead into a collapsed state by applying a compressive force to the medical lead, percutaneously delivering the collapsed medical lead into the patient adjacent tissue to be treated, and placing the medical lead into an expanded state by releasing the compressive force. In one preferred method, the stimulation lead is used to stimulate tissue, such as spinal cord tissue.
