6 Month Study Results
PROMISE II is a landmark multi-center, prospective pivotal study of the LimFlow System conducted at 20 U.S. centers in 105 No-option CLTI patients typically excluded from other clinical studies. All patients were confirmed as “No-Option” and facing imminent amputation by an independent review committee of vascular surgeons. Patients were enrolled between December 2020 to March 2022. This study was a success and met its primary endpoint.
