1. An external vein support comprising an elongate axial body including an axis, said body is plastically deformable by at least one of:
- stretching, bending, twisting, and any combination thereof, relative to said axis;
wherein said elongate body has a first end and a second end with a channel therebetween, said elongate body having a relaxed pre-deformation configuration, said channel sized to freely receive the vein when said body is in said pre-deformation configuration so that an axis of said channel extends along an axis of the vein;
said body being manually manipulatable from said pre-deformation configuration to a relaxed post-deformation configuration selected in response to the vascular system, said channel in said post-deformation configuration supporting receiving the vein therein so as to inhibit tissue-response induced occlusion of the desired flow.

29. An external vein support comprising an elongate resilient axial body including an axis, said body is plastically deformable by at least one of:
- stretching, bending, twisting, and any combination thereof, relative to said axis;
wherein said external vein support body comprises a plurality of fibers arranged so that at a first average diameter, the resilience of said body relative to said axis is substantially greater than at a second average diameter. - View Dependent Claims (30, 31, 32, 33, 34, 35)

40. An external vein support comprising an elongate axial body including an axis, said body is plastically deformable by at least one of:
- stretching, bending, twisting, and any combination thereof, relative to said axis;
wherein said external vein support body includes at least two plastically deformable elements intersecting to form a braiding angle, wherein a plasticity of said support increases along a longitudinal axis as said angle decreases from a larger angle in a support first less extended position, to a smaller angle in a support second more extended position. - View Dependent Claims (41, 42, 43, 44)
