DETECTING AND TREATING NERVOUS SYSTEM DISORDERS

摘要

Some embodiments of a mapping device may be capable of passing through cerebral veins and other cerebrovascular spaces to provide electrophysiological mapping of the brain. These embodiments of the device may also be capable of providing, simultaneously or separately, ablation energy or other treatments to targeted brain tissue. In such circumstances, a user may be enabled to analyze an electrophysiological map of a patient's brain and, at the same time or within a short time period before or after the mapping process, may be enabled to apply ablation energy for treatment of a central nervous system disorder. Such treatment may be accomplished without the use of invasive surgery in which the brain is accessed through an opening in the patient's cranium.

主权项

1. An electrophysiological brain mapping device, comprising
an elongated body having a distal end to pass through one or more cerebral veins proximal to brain tissue, the elongated body defining a fluid input conduit in fluid communication with a fluid input port near the distal end and defining a drain conduit in fluid communication with a drain port near the distal end; one or more electrodes to detect electrophysiological signals in a portion of the brain and to deliver ablation energy, the electrodes being disposed near the distal end of the elongated body; and a balloon structure disposed near the distal end so as to surround the fluid input port, the drain port, and the electrodes, the balloon structure being adjustable from a non-expanded state to an expanded state when a fluid flows from the input port and to the drain port.
