'The insertion site may be closed with a closure device that uses collagen to seal the opening in the artery or with sutures. Your physician will determine which method is appropriate for your condition.'

'Vascular Closure Devices
Percutaneous vascular closure devices (PVCDs) have been used for hemostasis of a femoral artery puncture site after catheterization since the 1990s. The advantages of their use, compared with the traditional methods of securing hemostasis by manual or mechanical compression, are that they increase patient comfort and decrease time to hemostasis and ambulation.

PVCDs can be broadly categorized in two types: those that use various mechanisms of collagen or other substance deposition at an arterial puncture site and others that use a suture to close the arteriotomy site.'
