A system for treating chronic inflammation may include an implantable microstimulator, a wearable charger, and optionally an external controller. The implantable microstimulator may be implemented as a leadless neurostimulator implantable in communication with a cervical region of a vagus nerve. The microstimulator can address several types of stimulation including regular dose delivery. The wearable charger may be worn around the subject's neck to rapidly (<10 minutes per week) charge an implanted microstimulator. The external controller may be configured as a prescription pad that controls the dosing and activity of the microstimulator.

A catheter based method and apparatus for reflectance generated absorption spectral analysis of chronic inflammatory vascular conditions such as seen with atherosclerotic plaque within a blood vessel or other body cavity or compartment. The use of a bright mid range infrared light (mid-IR) source yields detectable reflected optical signals that may be sampled from an area smaller or larger than the typical diameter of a mammalian cell. The mid-IR light is delivered at selected mid-infrared wavenumbers. Using the apparatus and methods, the reflectance spectra and reflectance generated absorption spectra of a target tissue can be compared to reference spectra to identify and distinguish normal epithelium from tissue containing physiological markers indicative of vascular disease or other inflammatory conditions.

The invention provides pharmaceutical compositions, methods for the treatment of, and related diagnostics and computer-implementable systems that relate to, the treatment of a variety of metabolic syndromes, including hyperlipidemia, weight gain, obesity, insulin resistance, hypertension, atherosclerosis, fatty liver diseases and certain chronic inflammatory states. In an additional aspect of the invention, compositions and methods of treatment are calibrated to the ileal brake response to surgical intervention e.g. Roux-en-Y gastric bypass (RYGB)) as both activate the ileal brake, which acts in the gastrointestinal tract and the liver of a mammal to control metabolic syndrome manifestations and thereby reverse or ameliorate the cardiovascular damage (atherosclerosis, hypertension, lipid accumulation, and the like) resulting from progression of metabolic syndrome.

It is now recognized that chronic inflammation is an important risk factor for the development of cancer. The proinflammatory cytokine IL-6 is implicated in cancer because it is important for the activation of STAT, a key regulator of cancer growth, survival, metastasis, immune evasion and angiogenesis. Increased IL-6 and Stat-3 exists in vitro in pancreatic cancer, malignant melanoma, papillary thyroid cancer, breast cancer, colon cancer, and prostate cancer cells with high basal expression of Toll-like receptor 3 (TLR3) and Wnt5a. IL6 / STAT3 activation, mediated by overexpressed TLR3 signaling, appears important in the tumor growth process, it may increase Wnt5a signaling, and be associated with increased cellular growth and migration. Using a novel inhibitor of pathologic TLR3 signaling (5-phenylmethimazole [C10]) we have demonstrated decreases in these markers plus suppression of cell growth and migration in human pancreatic cancer, malignant melanoma, papillary thyroid cancer, breast cancer, colon cancer, and prostate cancer cells.
