1. A cannula for moving fluids between a pump and a circulatory system of a patient, the cannula comprising:
- a liner comprising an intermediate portion between a proximal portion and a distal portion and a lumen extending between the proximal and distal portions, wherein at least the intermediate portion is constructed from a tissue in-growth material for supporting the growth of endothelial cells, the proximal portion is configured for connecting to the pump and the distal portion is configured for connecting to the circulatory system; and
a jacket surrounding at least a part of the liner.

Abstract
A cannula for moving fluids between a pump and the circulatory system of a patient. The cannula includes a liner having an intermediate portion between a proximal portion and a distal portion, and a lumen extending between the proximal and distal portions. At least the intermediate portion of the liner is constructed from a tissue in-growth material for supporting the growth of endothelial cells. A jacket surrounds at least part of the liner.
