People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

New material for creating artificial blood vessels developed by Swiss scientists

RATE THIS! +35

Researchers have developed artificial blood vessels made from a special elastomer material. The artificial blood vessels are designed to be broken down by the body and replaced with its own tissue. At the end of this restorative process, a natural, fully functional vessel will be in place.

 
Arteriosclerotic vascular disorder is one of the most common causes of death in industrialized countries. A bypass operation is often the only solution. Normally, blood vessels are taken from another part of the patient’s body and used to replace the damaged vessel. The artificial materials used so far are not fully compatible with body tissue, and the blood vessel can easily become blocked.
 
To produce the new vascular prostheses, polymer solutions were spun in an electrical field to form very fine threads and wound onto a spool. “The wall of these artificial blood vessels is very similar to that of natural ones,” says Heinz Schima of the Medical University of Vienna.
 
The polymer fabric is slightly porous, so it allows a small amount of blood to permeate the material. This enriches the wall with growth factors, encouraging migration of endogenous (body’s own) cells. A few more preclinical trials are necessary before the artificial blood vessels can be used in humans, which the researchers expect in a few years.

Very good prospect - artificial blood vessels could help surgeries and improve cardiovascular treatments. Clinical trials are the key step ahead Reply
