Pellethane valves merit further preclinical optimization; leaves open durable patency in human venous disease.
Does a Pellethane prosthetic venous valve improve patency compared to an umbilical vein venous valve in a canine jugular vein model?
Pellethane prosthetic venous valves showed slightly longer patency (up to 5 days) compared to umbilical vein valves (occluded by 48 hours) in a canine model, suggesting potential for future development.
Hill et al. (1985) studied this question.
