Treatment of Acute Medical Conditions

Electrical stimulation of neural activity in the neural innervation of the spleen that is associated with neurovascular bundles provides a useful way to treat acute medical conditions, such as trauma, hemorrhaging and shock.

Treatment of Disorders Associated with Inflammation

Stimulation of neural activity in a nerve supplying the spleen, wherein the nerve is adjacent to the splenic artery at a position where the splenic artery is not in direct contact with the pancreas, can modulate pro- and anti-inflammatory molecules levels, thereby reducing inflammation and providing ways of treating disorders, such as disorders associated with inflammation. The invention provides improved ways of reducing inflammation with minimized off-target effects, in particular surgical trauma.
