What is it indicated for?
The IB-Stim is a percutaneous electrical nerve field stimulator (PENFS) system intended to be used in patients 8-21 years of age with functional abdominal pain associated with irritable bowel syndrome (IBS) and functional dyspepsia (FD). The IB-Stim is intended to be used for 120 hours per week, using 1 device per week for 4 consecutive weeks, through application to branches of Cranial Nerves V, VII, IX and X, and the occipital nerves identified by transillumination, as an aid in the reduction of pain when combined with other therapies for IBS and FD. FD patients for whom IB-Stim is indicated have also been shown to experience reduction of nausea symptoms.
