Abstract
A method for making a tubular device includes coating a first surface of a thin sheet, rolling the sheet such that side edges of the sheet are disposed adjacent one another with the coating disposed inwardly, creating a longitudinal seam along the side edges to create a sleeve, and attaching a tubular structure around the sleeve. In another embodiment, the method includes coating a first surface of a thin sheet, wrapping the sheet partially around a mandrel with the coating disposed inwardly, positioning a slotted tube around the sheet and mandrel, attaching the tube to the thin, and trimming any excess material of the sheet. In another embodiment, the method includes coating an outer surface of a thin sleeve, inverting the sleeve, and attaching a tubular structure around the inverted sleeve, thereby providing a tubular device including a lubricious, hydrophilic, and/or otherwise coated inner surface.
