Abstract

Disclosed herein is a method comprising transporting a conduit and a template through a guide tube; the template being disposed on an outer surface of the conduit between the conduit and the guide tube; and transferring a texture from the template to the conduit as the conduit and the template are transported through the guide tube. Disclosed herein too is an apparatus comprising a guide tube; the guide tube being operative to facilitate a transfer of a pattern from a template to a conduit; a first feed spool and a first take-up spool for feeding the conduit through the guide tube and for taking up the conduit after it has travelled through the guide tube respectively; and a second feed spool and a second take-up spool for feeding the template through the guide tube and for taking up the template after it has travelled through the guide tube respectively.

First claim

What is claimed is:

1. A method comprising:
transporting a conduit and a template through a guide tube, the template being disposed on an outer surface of the conduit between the conduit and the guide tube;
centering the conduit in the guide tube via a centering device;
guiding the conduit into the guide tube via a conical guide that communicates with the guide tube; and
transferring a texture from the template to the conduit as the conduit and the template are transported through the guide tube, wherein the template is in the form of a single film that is wrapped around the entire circumference of the conduit, and wherein the conduit is a catheter.

2. The method of claim 1 , further comprising pressurizing the template, conduit, or the guide tube.

3. The method of claim 2 , wherein the pressurizing the conduit or the template is accomplished by increasing fluid pressure within the conduit or within the template.

4. The method of claim 1 , further comprising unwrapping the template after the transferring of the texture is completed.

5. The method of claim 1 , further comprising curing the texture on the conduit.

6. The method of claim 5 , wherein the curing is accomplished by heat and/or by radiation.

7. The method of claim 1 , wherein the texture comprises a plurality of patterns.
