Abstract
A method for applying a paving material to a tissue surface is described. The method involves positioning a non-fluent polymeric material at the surface to be paved, rendering the material fluent, contacting the fluent polymer with the tissue surface, and allowing the polymer to return to its non-fluent condition.
Claims21
A method for forming a biocompatible polymer coating on a tissue surface of a lumen in a body vessel or hollow organ which comprises the steps of:
- a) providing a biocompatible polymeric material which is non-fluent at body temperature and which is fluent at an elevated temperature;
- b) heating the material to render the polymer fluent;
- c) contacting the fluent polymer with a surface to be coated;
- and
- d) allowing the fluent polymer to cool into a non-fluent biocompatible polymeric coating on the surface.
A method for forming a biocompatible polymer coating on a tissue surface of a lumen in a body vessel or a hollow organ which comprises the steps of:
- a) providing a biocompatible polymeric material having a variable degree of fluency in response to a stimulus;
- b) providing the stimulus to the material to render the polymer fluent;
- c) contacting the fluent polymer with a surface to be coated;
- and
- d) allowing the fluent polymer to return to a non-fluent state, thereby providing a biocompatible polymeric coating on the surface.
A method for forming a biocompatible polymer coating on a tissue surface which comprises the steps of:
- a) providing a biocompatible polymeric material which is non-fluent at body temperature and which is fluent at an elevated temperature;
- b) heating the material to render the polymer fluent;
- c) contacting the fluent polymer with a surface to be coated;
- and
- d) allowing the fluent polymer to cool into a non-fluent biocompatible polymeric coating on the surface, the coating defining a passageway open to fluid flow.
