Abstract
A method for coating the lumen of a tube comprises the steps of inserting the distal opening of a tube into a first coating solution, drawing the first coating solution into the lumen of the tube, draining the first coating solution from the lumen leaving a film of the first coating solution on the lumen of the tube, and curing the first coating solution. This leaves a first coating on the lumen of the tube. A coating apparatus comprises a pallet, and one or more dip funnels. The pallet comprises a manifold and is configured to fluidically connect the manifold to one or more tubes. The one or more dip funnels are configured to hold a coating solution and are located below the pallet so that when the pallet is moved vertically, the one or more tubes are inserted into the dip funnels.
