It's a battlefield in the stim market right now, and MRI ability is one of the points of contention. Nuvectra will be conditional for extremity only; and depends upon where the device is placed in the spine (typical for all companies). Medtronic has full-body with their main device (as well as the new Intellis system that will hopefully be approved this year by FDA). Boston has a full-body device, but it's larger; i.e. Possible patient discomfort. Their Spectra is conditional for head only. So Nuvectra's move is a GOOD one, stays competitive.
