Recently 3 randomized trials were presented in treating FP ISR; the EXCImer Laser Randomized Controlled Study for Treatment of FemoropopliTEal In-Stent Restenosis (EXCITE ISR) trial (randomized laser + PTA vs PTA alone), the RELINE trial (Propaten Bioactive Surface vs. standard balloon angioplasty for treatment of in-stent restenosis in the superficial femoral artery) and the Randomized Femoral Artery In-Stent Restenosis (FAIR) Trial. All these studies showed superiority over PTA in treating FP ISR. Early animal data (porcine model of FP ISR) and feasibility human data (JetStream ISR study) have shown that the JetStream device is effective in ablating restenotic tissue within restenotic FP stents and had no safety concerns within well apposed stents and in the absence of Class III and IV fractures.
