Patients with damaged arteries can now add on to their optimism. Scientists developed a new material that can help such patients to regenerate new arteries! Thanks to the engineers and scientists of the Virginia Commonwealth University.
The new material — a blend of polydioxanone (PDO) and elastin fibers – is to be used for vascular grafts to enhance elasticity and bioactivity of the graft. The material could in the future be implanted in patients undergoing coronary artery graft surgery.
The PDO, a synthetic polymer used in suture materials for years, is biodegradable. Lead author Gary Bowlin, Ph.D., the Harris professor of biomedical engineering in the VCU School of Engineering explained that the material’s composition reinforces the mechanical strength of the graft, and it is critical for holding the blood pressure and forces during the period of regeneration process’ occurrence.
Bowlin said,
We have created a vascular graft with a combination of strength and bioactivity – two things we need to maintain and regenerate the graft. Although the body is the best bioreactor for tissue regeneration or wound healing, we hope this new material will be recognized by the body as an environment conducive for regeneration.
