Catheters with lubricious linings and methods for making and using them
First Claim
1. A method for making a tubular device sized for introduction into a body lumen, comprising:
- providing a thin sheet comprising first and second side edges;
coating a first surface of the thin sheet with a coating having one or more desired properties;
rolling the thin sheet such that the first and second side edges are disposed adjacent one another and the coating is disposed inwardly;
creating a longitudinal seam along the first and second side edge to create a sleeve; and
attaching-a tubular structure around the sleeve.

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.

13. A method for making a tubular device sized for introduction into a body lumen, comprising:
-
coating a first surface of a thin sheet with a coating imparting one or more desired properties to the first surface;
wrapping the thin sheet at least partially around a mandrel with the first surface disposed inwardly;
positioning a slotted tube around the thin sheet and mandrel;
attaching the slotted tube to the thin sheet to form a tubular structure; and
removing the tubular structure from the mandrel. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A method for making a tubular device sized for introduction into a body lumen, comprising:
-
providing a sheet of material comprising a first surface and a second surface;
coating the first surface of the sheet with a coating to impart the first surface with one or more desired properties; and
rolling the sheet until longitudinal edges of the sheet are disposed adjacent one another; and
attaching the longitudinal edges to one another to form a continuous wall defining a lumen. - View Dependent Claims (26, 27, 28)

29. A method for making a tubular device sized for introduction into a body lumen, comprising:
-
providing a thin sheet comprising a first surface and a second surface;
coating the first surface with a coating to impart the first surface with one or more desired properties;
forming the thin sheet into a thin sleeve such that the first surface defines an inner surface; and
attaching a tubular structure around the thin sleeve, thereby providing a tubular device comprising an inner surface with the one or more desired properties.
