Studies of biocompatibility of the wireless bladder monitoring system. Images for (A) H&E, (B) trichrome, and (C) M1/M2 inflammatory responses of bladder muscle near a strain gauge sutured onto the outer surface of a normal bladder. Images for (D) H&E, (E) trichrome, and (F) M1/M2 inflammatory responses of bladder muscle near a strain gauge sutured onto the outer surface of a bladder after a partial cystectomy. Quantitative histological evaluation of (G) collagen, (H) M1, and (I) M2 inflammatory responses for bladder muscle near strain gauges applied to a normal bladder and one with partial cystectomy.
