Esprit BTK offers treatment for people with peripheral artery disease (PAD) below the knee (BTK). Abbott designed it to keep arteries open and deliver the drug everolimus to support vessel healing. Following the therapy, the stent completely dissolves over time.

According to Abbott, Esprit BTK is the first resorbable scaffold of its kind for use BTK. The company constructed the stent from material similar to dissolving sutures. Esprit BTK is implanted through a minimally invasive, catheter-based procedure via a small incision in the leg.

Once the stent clears the blockage, the scaffold helps seal the vessel and provide support until the vessel can remain open on its own. After that point, the scaffold resorbs.
