Arterial Remodeling Technologies (ART) has disclosed the results of an in vivo study of 48 porcine arteries implanted with its biodegradable stent. The study demonstrated that the ART stent’s biodegradation is measurable and begins at the first day of implant.

The study also demonstrated that the ART stent retains high radial strength, thus maintaining its structural integrity during biodegradation and that the ART stent causes virtually no inflammation of the blood vessel wall.

Machiel van der Leest, CEO of ART, said: “We will continue to disclose new data related to the ART bioresorbable stent platformadditional data that dramatically validates the Company’s innovative approach of simultaneously balancing biocompatibility, biomechanics and bioresorption in a bioresorbable PLA (polylactic acid) stent.”

Mr Leest said: “We have designed ARTs next-generation bioresorbable coronary stent to provide an impermanent yet effective scaffold that will dismantle and loose its primary mechanical scaffolding function after three months which is the period universally accepted by experts as necessary to permit the healing process to stabilize the artery following the trauma caused by an angioplasty. The complete resorption of all the monomers (basic elements that form polymers) is estimated to occur within 18 months.”
