What is Angio-Seal™?

Angio-Seal 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 does Angio-Seal stop 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.

How long is Angio-Seal left in place?

Your body will absorb Angio-Seal within 90 days. Your healthcare provider may need to do a Doppler ultrasound to check if it has been absorbed.

When should I contact my healthcare provider?

  • You have a fever.
  • Your groin is red, painful, and warm to the touch.
  • You have bleeding or increased swelling at the site.
  • 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.
