1. A process for forming a polymeric coating on an interior surface of a hollow organ or tissue lumen, comprising:
- applying, from a distal end of a catheter, a prepolymer fluid to an interior surface of a hollow organ or tissue lumen to be coated; and
polymerizing the prepolymer fluid adjacent the surface to form thereon a polymer coating.

Abstract
A novel process for paving or sealing the interior surface of a tissue lumen by entering the interior of the tissue lumen and applying a polymer to the interior surface of the tissue lumen. This is accomplished using a catheter which delivers the polymer to the tissue lumen and causes it to conform to the interior surface of lumen. The polymer can be delivered to the lumen as a monomer or prepolymer solution, or as an at least partially preformed layer on an expansile member.

44. A method of forming a layer of polymeric material on a tissue surface internally of a mammal, comprising:
-
applying to a tissue surface internally of a mammal an initially entirely fluent, pre-polymeric material that is activatable to a non-fluent, polymeric condition; and polymerizing the pre-polymeric material on the tissue surface to form thereon a layer of polymeric, non-fluent material.

-
45. A method comprising:
-
applying to a tissue surface internally of a mammal an initially entirely fluent, pre-polymeric material that is activatable to a non-fluent, polymeric condition by exposure to actinic light; and thereafter applying to the material actinic light for a sufficient length of time to effect in situ conversion of the material from a pre-polymeric, fluent to a polymeric, non-fluent condition.

46. A method for applying to a surface of mammalian tissue a polymeric, non-fluent material comprising:
-
via minimally-invasive surgery, applying internally of a mammal an initially entirely fluent, pre-polymeric material to the tissue, the material being activatable to a non-fluent, polymeric condition by exposure to actinic light; and thereafter applying to the material actinic light for a sufficient length of time to effect in situ conversion of the material from a pre-polymeric, fluent to a polymeric, non-fluent condition.
