artery disease affects 15 million people in the United States and is a leading
cause of death worldwide. The Absorb bioresorbable heart stent is the world’s
first FDA-approved dissolvable stent to treat coronary artery disease.
What Is the Absorb
The Absorb stent is a naturally dissolvable heart stent that
treats coronary artery disease.
Typically, heart stents are made of metal and remain in the
body forever. Absorb, on the other hand, is a stent made of polylactide, a
naturally dissolving material similar to dissolving stitches.
The first of its kind, the Absorb stent begins dissolving
after 1 year and is completely absorbed 3 years after implantation. At that
point, the artery has healed and blood flow is restored.
All but two small metallic markers dissolve completely. Those markers tell physicians where the device was implanted.
How Does the Absorb Stent Work?
Once implanted, the dissolvable stent opens the clogged artery and restores blood flow. It’s flexible and allows the artery to pulse and flex naturally.
The stent releases everolimus, a medication that prevents scar tissue from forming and potentially narrowing the artery. After the blockage clears, the blood vessel heals within months so it can stay open on its own.
Unlike metal stents, a dissolvable stent allows the vessel to heal and function after the stent is no longer needed.
The Absorb stent’s performance happens in 3 phases:
- Revascularization: From implantation to about 6 months post-implantation, the stent provides vessel support. It also suppresses neointimal hyerplasia, or scar tissue, so that it does not cause the artery to become too narrow and hinder the healing process.
- Restoration: From 6 months to 18 months post-implantation, the stent becomes a passive implant and begins dissolving. The neointima, or lining of the artery, also begins to form.
- Resorption: From 18 months to 3 years post-implantation, the stent eventually dissolves completely, and the vessel heals.
Benefits of the Absorb Stent
Coronary artery disease is a temporary problem, so it can be
treated with a temporary solution.
To understand this concept more clearly, it’s helpful to
relate the stent to a cast: After a broken bone heals, a cast is no longer
needed. When a heart vessel heals, the stent becomes obsolete.
Patients can feel immediate relief from chest pain caused by coronary artery disease with the implantation of a dissolvable stent.
However, the benefits are not only short-lived. The Absorb stent has long-term effects:
- Much like with metal stents, it reduces risk of future blockages.
- Unique to the Absorb stent, it allows the artery to pulse and flex naturally.
- The Absorb stents allow doctors to offer future interventions more easily, if necessary. This is especially important if bypass surgery is required in the future, as there is nothing in the way.
