Abstract
A method for coating a cannula having a proximal portion opposite a distal portion and a cannula body extending between the distal portion and the proximal portion includes, providing the cannula body, loading the cannula body onto a mandrel, dipping the cannula body into a polymer solution to form a dip coating along an inner surface of the cannula body, and applying an outer layer of polymer onto a cannula.

A method of coating a cannula for use with a circulatory support device, the cannula having a proximal portion opposite a distal portion and a cannula body extending between the distal portion and the proximal portion, the cannula body defined by an inner surface and an outer surface, the method comprising:
- providing the cannula body;
- loading the cannula body onto a mandrel;
- dipping the cannula body into a polymer solution to form a dip coating along the inner surface of the cannula body;
- and
- applying an outer layer of polymer onto the cannula.
