In this vignette, I continue to follow the encapsulation tissue track that accompanies the intramuscular electrode implant. Here is the cross section of the encapsulation along the lead, and here a cross section of the encapsulation of the deinsulated end of the electrode and the barb section. I call your attention to layer of cells encapsulating one of the barbs and the terminal end of the barb. I interpret these results to mean that the encapsulation layer extends throughout the entire length of the implanted device. If this encapsulation is comprised of a tight cell layer adjacent to the implant it is acting as both an mechanical stabilizer and a pathogen barrier.
