The Absolute Pro Vascular Self-Expanding Stent System is a medical device designed primarily for use in the treatment of vascular diseases, including peripheral artery disease (PAD) and other conditions that require the support and restoration of blood vessel patency. Manufactured by Abbott Vascular, this stent system is intended for use in the femoral and popliteal arteries, which are crucial vessels in the lower limbs.

Design and Features

The Absolute Pro stent system is a self-expanding metallic stent made from a high-strength, biocompatible material—usually a form of nitinol (a nickel-titanium alloy). Nitinol is known for its unique "shape memory" properties, meaning it can return to a predetermined shape after being deformed. This feature is critical in the design of self-expanding stents, allowing them to automatically expand once deployed inside the artery, exerting outward pressure to hold the vessel open.

The stent’s design incorporates a mesh-like structure that provides strong radial force, ensuring the artery remains open after treatment. The open-cell architecture helps in reducing vessel restenosis (re-narrowing of the artery) by allowing for optimal flexibility and vessel conformability, which is important in the dynamic and often challenging environment of blood vessels. Additionally, the stent has a low-profile delivery system, meaning it can be introduced into the body through minimally invasive procedures, such as angioplasty, which involves the use of a catheter to place the stent.

Indications for Use

The Absolute Pro stent system is indicated for use in the treatment of vascular lesions caused by occlusions or stenosis in the femoral or popliteal arteries, which are the primary arteries supplying blood to the legs. Conditions like peripheral artery disease (PAD), which results from the narrowing or blockage of these arteries due to a buildup of plaque, can lead to severe consequences like limb ischemia, pain, or even amputation if not properly managed. The stent helps to restore adequate blood flow by keeping the artery open, improving circulation and alleviating symptoms.

It is typically used in patients who are suffering from significant arterial narrowing or blockages that cannot be resolved with less invasive treatments such as balloon angioplasty alone. In some cases, it may be used in conjunction with drug-coated balloons or other vascular interventions to optimize results.

Clinical Benefits and Safety

One of the major advantages of the Absolute Pro stent system is its flexibility and ability to conform to the natural curves of the arteries. This minimizes complications during deployment and reduces the risk of stent fracture, a common concern with other stents, especially in the challenging anatomy of the femoral-popliteal region. The stent's self-expanding nature also minimizes the need for post-deployment balloon angioplasty, simplifying the procedure and reducing the time required.

 

Conclusion

The Absolute Pro Vascular Self-Expanding Stent System represents a significant advancement in vascular stenting technology, providing physicians with a reliable tool for treating vascular lesions in the lower extremities. By using a self-expanding stent made from durable nitinol, it offers strong mechanical support, excellent flexibility, and long-term effectiveness in improving blood flow. This system has become a crucial option in the management of peripheral artery disease and similar vascular conditions, offering enhanced patient outcomes and a lower risk of complications.
