Brief Summary

To evaluate the safety and effectiveness of MynxGrip, in hemostasis of common femoral artery puncture site, compared with manual compression hemostasis in patients who have undergone diagnostic or interventional endovascular procedures utilizing a 5F, 6F or 7F procedural sheath.

Conditions

Endovascular

Keywords

Vascular closure

Outcome Measures

Primary Outcomes (2)

• Primary Effectiveness Endpoint: Time to Hemostasis

  The time to hemostasis is defined as the time from the sheath removal to the time to achieving hemostasis for the subject. The "hemostasis" here refers to that at the puncture site, there is no pulsating bleeding, nor expansionary/progressive hematoma.

  Post procedure (time from the sheath removal to the time to achieving hemostasis)

• Primary Safety Endpoint: Major Complication Rate

  Defined as major complications during procedure, at discharge, and 30 days post procedure: vascular injury or vascular repair required; Permanent access site-related nerve injury; Access site-related nerve injury requiring a surgery; Access site-related bleeding requiring transfusion; New ipsilateral lower extremity ischemia discovered, which requires invasive/noninvasive intervention; Local access site-related infection combined with other indicators, which requires intervention; Classic signs/symptoms occurred in a short time after receiving the specified hemostasis procedures and generalized infection with positive blood culture, sepsis, which requiring intervention; Inflammatory reaction, including the local reaction and discharge of pus, which requires intervention

  Through 30 days post procedure

Secondary Outcomes (5)

• Secondary Effectiveness Endpoint: Time to Ambulation

  Post procedure

• Secondary Effectiveness Endpoint: Length of Hospital Stay

  Index procedure through discharge

• Secondary Effectiveness Endpoint: Procedure Success Rate

  Index procedure

• Secondary Effectiveness Endpoint: Device Success Rate

  Intraoperatively

• Secondary Safety Endpoint: Minor Complication Rate

  Through 30 days post procedure
