is a closure device. It stops the bleeding after angiography procedures, such as cardiac catheterization. During this procedure, a catheter punctures an artery in your groin.

How Angio-Seal stops the bleeding:

Angio-Seal is placed after the catheter is removed. A dissolvable anchor is inserted on the inside of your artery. An absorbable sponge made of collagen is placed on the outside of your artery. A stitch pulls the anchor and collagen together to form a seal. The seal stops the bleeding and allows your artery to heal. Your body will absorb Angio-Seal within 90 days.

Contact your healthcare provider if:

  • You have a fever.
  • Your groin is red, painful, and warm to the touch.
  • You have severe pain or cramps in your leg that Angio-Seal was placed.
  • You see a change in the color of your leg.
  • You have questions or concerns about your condition or care.

Follow up with your healthcare provider as directed:

Your healthcare provider may need to do a Doppler ultrasound to check if Angio-Seal has been absorbed. Write down your questions so you remember to ask them during your visits.
