Components of the Angioseal Closure Device
The Angioseal closure device comprises three essential components that work together to effectively seal puncture sites after angioplasty and atherectomy procedures. Each component plays a crucial role in achieving the desired outcome.
Collagen Plug:
The collagen plug forms the core of the device. Composed of bovine or porcine collagen, this soft, biocompatible material gently expands when in contact with blood. Acting like a sealant, it fills the puncture hole, creating an initial barrier against bleeding. The collagen plug is secured in place by the other components, ensuring a stable closure.
Nitinol Clip:
The nitinol clip is a small, spring-like device crafted from nitinol, a superelastic alloy. Its primary function is to hold the collagen plug firmly in position. The clip is designed to apply an optimal amount of pressure, preventing the plug from dislodging or retracting. The nitinol clip ensures a secure seal, reducing the risk of bleeding complications.
Suture:
The suture is a fine thread that provides additional reinforcement to the collagen plug and nitinol clip. It is typically made from polyester and acts as a safety measure, ensuring the closure remains intact even in the event of any unexpected movements or forces applied to the puncture site. The suture adds an extra layer of protection, further minimizing the chances of bleeding and hematoma formation.

Mechanism of Action: Simplicity that Seals
The Angioseal closure device’s mechanism of action is a testament to its ingenuity and effectiveness. It’s a procedure that unfolds like a carefully choreographed dance, with each component playing a vital role in achieving a secure and lasting closure.
First, the collagen plug, a soft and pliable material, is gently inserted into the puncture site. It acts like a plug, filling the opening and creating an initial barrier against blood leakage.
Next, a nitinol clip takes center stage. This robust clip is deployed to firmly embrace the collagen plug, providing additional support and preventing it from dislodging.
Finally, like a meticulous tailor, the procedure concludes with the secure placement of a suture. This suture reinforces the closure, ensuring that the seal is impenetrable and long-lasting.
This simple yet effective mechanism of action has revolutionized angioplasty and atherectomy procedures, enabling physicians to perform these interventions with greater confidence and precision. The Angioseal closure device has become an indispensable tool in the interventional cardiologist’s arsenal, paving the way for safer and more efficient patient care.
