ABSTRACT:
A prosthetic blood conduit comprises two porous concentrically associated tubes with a helical spring enclosed therebetween. Spring strength and frictional engagement between the spring and tubes enables the conduit to resist collapse under a wide variety of stress forces. Convolutions in the tube walls provide flexibility without kinking.
