Trial Outcomes & Findings for Clinical Study to Evaluate the Safety and Performance of MANTA Vascular Closure Device (NCT NCT02521948)

NCT ID: NCT02521948

Last Updated: 2018-10-29

Results Overview

Composite endpoint that includes any of the following adverse events: * Access site-related bleeding requiring blood transfusion or vascular repair * Vascular injury requiring repair (e.g. perforation, dissection, arterio-venous fistula, retroperitoneal bleed, pseudoaneurysm) * Femoral artery stenosis at the access site requiring intervention * New ipsilateral lower extremity ischemia causing a threat to the viability of the limb * Access site-related infection requiring intravenous antibiotics and/or extended hospitalization * New onset access site-related neuropathy in the ipsilateral lower extremity requiring surgical repair * Permanent access site-related nerve injury (lasting\>30 days)

PRIMARY outcome

Timeframe: Within the first 10 minutes of cutting the MANTA suture

Hemostasis at the puncture site within 10 minutes of cutting the MANTA suture without need for manual or mechanical compression and without later re-bleeding (trivial or subcutaneous oozing will not be considered bleeding; light finger pressure to control subcutaneous oozing will not be considered manual compression)
