Bored hollow lumen
A manufacturing process forms a bored hollow lumen. The manufacturing process includes providing a solid rod of a bioresorbable material and boring a hole axially through the solid rod. The manufacturing process also includes modifying surface defects formed on a luminal surface by the boring, the luminal surface defining the hole, thereby forming the bored hollow lumen. A bored hollow lumen includes a lumen wall including a bioresorbable material. The lumen wall has an abluminal surface and a luminal surface. The luminal surface defines a bore through the bored hollow lumen. The bioresorbable material has a uniform crosslinking density.
1. A bored hollow lumen comprising:
a lumen wall comprising a bioresorbable material, the lumen wall having an abluminal surface and a luminal surface, the luminal surface defining a bore through the bored hollow lumen; and
an overbraid on the abluminal surface;
wherein the bioresorbable material has a uniform crosslinking density.
2. The bored hollow lumen of claim 1 , wherein the bioresorbable material is poly(glycerol sebacate).
3. The bored hollow lumen of claim 1 further comprising an outer coating over the overbraid.
4. The bored hollow lumen of claim 1 further comprising an inner coating on the luminal surface.
5. The bored hollow lumen of claim 1 , wherein the inner coating comprises at least one additive encouraging endothelial cell growth on the luminal surface.
6. The bored hollow lumen of claim 1 , wherein the lumen wall has a uniform radial thickness.
7. The bored hollow lumen of claim 1 , wherein the luminal surface defines a bore hole having a diameter of less than 6 mm.
8. The bored hollow lumen of claim 1 , wherein the luminal surface has a surface feature selected from the group consisting of microgrooves, an embossment, bores, scores, a microarchitecture, and combinations thereof.
