Experimental data on the use of carbon-coated medical implants and pro
stheses are described. It was found that the best results are achieved
with carbyne coatings. Carbyne is the linear carbon form based on the
sp bond. Carbyne-covered material is produced by specific chemical an
d physical processes. From long-term experiments an excellent result w
as obtained in biocompatibility, thromboresistivity and flexibility of
vascular prostheses, urethra prostheses and endoprostheses. Applicati
on of carbyne-coated prostheses increases the probability of positive
operation results by 30% and widens the operating capabilities especia
lly for small-diameter veins and arteries.
