A blocked blood vessel is usually
replaced by another vessel taken from the body or by an artificial blood
vessel.
Scientists at Vienna University of
Technology and Vienna Medical University in Austria have developed artificial
blood vessels that are made from biocompatible and biodegradable thermoplastic
polyurethanes that transform into biological ones when implanted.
An Artificial Blood Vessel That can Help Test Medical Devices Used for Clot Removal
This in-vitro platform permitted quantification and characterization of the pattern and timing of endothelial cell injury with various thrombectomy devices.

This latest breakthrough could allow surgeons to carry out more bypass operations and reduce the risk of blockages associated with smaller artificial blood vessels.
"By selecting very
specific molecular building blocks we have succeeded in synthesizing a polymer
with the desired properties," said Robert Liska from Vienna University of
Technology's synthetic chemistry institute.

A gene that plays a vital role in blood vessel formation has been discovered by University of Leeds researchers.
The blood vessel created by the scientists is slightly porous and initially allows a small amount of blood to steep through, encouraging nearby tissues to thrive. Over time natural endogenous cells replace the artificial blood vessel.
The researchers tested the new vessels on laboratory rats, implanting them and checking up on them six months later. "We did not find any aneurysms, thromboses or inflammation. The natural cells had also turned the artificial vessel into natural body tissue," said, Helga Bergmeister from Vienna Medical University.
