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.

16 . A computer-implemented method for treating a medical condition involving stimulating neural activity of one or more nerves adjacent to a splenic arterial loop comprising:
controlling at least one electrode in signaling contact with the one or more nerves wherein at least one controller is electrically coupled to the at least one electrode, the at least one controller configured to control operation of the at least one electrode to apply an electrical signal to the one or more nerves, wherein the electrical signal has a waveform that comprises one or more pulse trains, and
applying a charge density per phase applied to the one or more nerves by the electrical signal is between 5 μC to 1100 μC per cm2 per phase, wherein the electrical signal produces an improvement in a physiological parameter in a subject, and wherein the improvement in the physiological parameter is one or more of a group consisting of: a reduction in a pro-inflammatory cytokine, an increase in an anti-inflammatory cytokine, an increase in a catecholamine, a change in an immune cell population, a change in an immune cell surface co-stimulatory molecule, a reduction in a factor involved in the inflammation cascade, a change in a level of an immune response mediator, and a decrease in splenic blood flow.
17 . The method of claim 16 , wherein the site is a position of the splenic artery separated from the surface of the pancreas by a distance in a range of from 0.5 cm to 4 cm.
18 . The method of claim 16 , wherein the site is at a splenic arterial loop.
19 . The method of claim 16 , further comprising the step of sending a set of control instructions that are performed by software in a machine readable form on a tangible storage medium.
20 . The method of claim 19 , wherein the software is suitable for execution on either a parallel or serial processor.
21 . The method of claim 16 , wherein the method further comprises providing a remote computer.
22 . The method of claim 21 , further comprising the step of providing a set control instructions that are located on the remote computer.
