Note: individual trials are not directly comparable and data is presented for observational purposes only.
- Total study population = 260 patients. Results presented include concomitant cohort only. Per IFU: when using the LDP Catheter, the LDP Catheter must be used in conjunction with a Zoom Catheter.
