Vascular Replacement (Physical Conduit)

Molecular classification
Medical Device, Physical Implant, Biomaterial
01

Overview

A vascular replacement (physical conduit) is an artificial or biological structure used to replace, bypass, or repair damaged blood vessels. These conduits serve as physical channels for blood flow when native vessels are diseased, injured, or otherwise unsuitable for direct repair. Options include autologous veins/arteries, synthetic prosthetics, allografts/xenografts, and tissue-engineered constructs. The choice depends on patient factors, site/caliber requirements, urgency, infection risk, and long-term patency needs.
