About Vascular Closure

There are two methods of closing the femoral artery after cardiovascular procedures – manual compression and vascular closure devices. Manual compression entails up to 30 minutes of firm manual pressure applied directly to the access site, which is often painful for the patient, followed by many hours of bed rest in a hospital recovery room. Physicians frequently choose to use a vascular closure device (VCD) as an alternative to manual compression because it stops the bleeding more quickly, thereby allowing patients to leave the hospital earlier. However, despite the benefits of VCDs, many patients find that deployment of a VCD is extremely painful. The Mynx addresses this shortcoming by eliminating the tugging and cinching of the artery that occurs with other closure devices. The sealant is designed for gentle placement on top of the artery without the use of a suture or permanent metal implant.
