How do bioresorbable stents work?
While traditional metal stents are permanent implants and can restrict vessel motion, the Absorb bioresorbable stent is made of a dissolving polymer, similar to dissolving sutures, allowing the artery to pulse and flex naturally.
How is a drug-eluting stent placed?
What Is the Procedure for Stent Placement? Once the artery is open, your doctor will place the drug-eluting stent against your artery walls. It will help hold it open and slowly release medication directly into your artery. After your surgery, you will need to take blood thinners long-term.
Are there dissolvable stents?
Absorb naturally dissolving stent After the stent is placed, it acts like a drug-eluting stent to keep the artery open. However, the Absorb stent dissolves over three years, leaving a restored and fully functioning artery. The benefits of a bioresorbable scaffold over a metallic stent are not immediate.
Why are drug-eluting stents better than bare metal?
The use of drug-eluting stents has been shown to be more effective in the prevention of restenosis than the use of bare-metal stents,1 and the use of newer-generation drug-eluting stents, as compared with first-generation devices,3,4 may also reduce the rate of stent thrombosis.
How long does a dissolvable stent last?
The flexible tube and the balloon are removed after placing the stent. Both traditional and dissolving stents often contain medication that is slowly released over time to treat the diseased area of the artery where the stent was placed. Dissolving stents fully disappear within about three years.
What is a bioresorbable vascular scaffold?
Bioresorbable Vascular Scaffold is similar in appearance to a stent, but is a non-metallic, non-permanent, mesh implant which gets absorbed gradually, dissolves over time and allows the artery to function naturally again, similar to the way a cast supports a broken arm and is then removed.
Are bioresorbable stents the future of interventional cardiology?
Bioresorbable stents: The future of interventional cardiology? The introduction of stents has drastically reduced target-lesion restenosis rates associated with percutaneous coronary angioplasty. Bare-metal stents were the first introduced, followed by drug-eluting stents, both of which had significant impacts on the complication rates.
Do bioresorbable polymers reduce stent inflammation?
STENTS WITH BIORESORBABLE POLYMERS As described above, the presence of a polymer on the stent predisposes it to inflammation. Therefore, it would be logical to hypothesize that a bioresorbable polymer would reduce the inflammation. This approach is typified by the second-generation paclitaxel-eluting stent (Synergy, Boston Scientific).
What is a Bioresorbable Scaffold?
Bioresorbable stents: Current and upcoming bioresorbable technologies Bioresorbable scaffolds (BRS) represent a novel horizon in interventional cardiology for the treatment of coronary artery disease.
What are the different types of stents?
Bare-metal stents were the first stents developed, followed by first- and second-generation drug-eluting stents, which have progressively reduced complication rates. Despite the improvements with conventional stents, persistent rates of restenosis and stent thrombosis remain, which can lead to increased coronary morbidity and mortality.
