Abstract
A system including an implantable neurostimulator device capable of modulating cerebral blood flow to treat epilepsy and other neurological disorders. In one embodiment, the system is capable of modulating cerebral blood flow (also referred to as cerebral perfusion) in response to measurements and other observed conditions. Perfusion may be increased or decreased by systems and methods according to the invention as clinically required.
Claims19
An implantable device for modulating cerebral blood flow in a human patient and configured to be implanted in the human patient, the device comprising:
- a therapy output adapted to receive a signal and deliver a corresponding stimulus to the patient's brain in response thereto, wherein the stimulus changes a characteristic of the patient's cerebral blood flow;
- and
- a therapy controller configured to automatically generate the signal representative of the stimulus based on measured cerebral blood flow and a determined cerebral blood flow trend and communicate the signal to the therapy output.

- and
- a therapy controller configured to automatically generate the signal representative of the stimulus based on measured cerebral blood flow and a determined cerebral blood flow trend and communicate the signal to the therapy output, the therapy controller further adapted to initialize a cerebral blood flow trend value by performing a sequence of perfusion measurements and taking the average of the sequence and storing the average in a memory in a trend variable as a trend value.
