Patent Images
1. A catheter assembly comprising:
- an expandable and collapsible structure having an outer surface, the expandable and collapsible structure being adapted to expand between a contracted state and a dilated state;
a guard bonded to the outer surface of the expandable and collapsible structure, the guard and the expandable and collapsible structure cooperatively defining a plurality of reservoirs; and
a coating disposed in the reservoirs, the coating including a bioactive agent, wherein the coating protrudes from the reservoirs when the expandable and collapsible structure is expanded to the dilated state.

Abstract
A catheter assembly includes an expandable and collapsible structure having an outer surface. The expandable and collapsible structure is adapted to expand between a contracted state and a dilated state. A guard is bonded to the outer surface of the expandable and collapsible structure. The guard and the expandable and collapsible structure cooperatively define a plurality of reservoirs. A coating disposed in the reservoirs. The coating includes a bioactive agent. The coating protrudes from the reservoirs when the expandable and collapsible structure is expanded to the dilated state.

16. A catheter assembly comprising:
-
an expandable and collapsible structure having an outer surface, the expandable and collapsible structure being adapted to expand between a contracted state and a dilated state, the expandable and collapsible structure being made of a first material; a guard bonded to the outer surface of the expandable and collapsible structure, the guard being made of a second material that is less flexible than the first material, the guard and the expandable and collapsible structure cooperatively defining a plurality of reservoirs with the outer surface of the expandable and collapsible structure forming base walls of the reservoirs and the guard forming sidewalls of the reservoirs; and a coating disposed in the reservoirs, the coating including a bioactive agent, wherein the coating protrudes from the reservoirs when the expandable and collapsible structure is expanded to the dilated state. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A catheter assembly comprising:
-
an expandable and collapsible structure having an outer surface, the expandable and collapsible structure being adapted to expand between a contracted state and a dilated state; a guard disposed on the outer surface of the expandable and collapsible structure, the guard including a fold line that extends between a first end of the guard and an oppositely disposed second end, the fold line having an area of reduced thickness, the guard and the expandable and collapsible structure cooperatively defining a plurality of reservoirs with the outer surface of the expandable and collapsible structure forming base walls of the reservoirs and the guard forming sidewalls of the reservoirs; and a coating disposed in the reservoirs, the coating including a bioactive agent, wherein the coating protrudes from the reservoirs when the expandable and collapsible structure is expanded to the dilated state.

31. A method of applying a coating to a catheter assembly, the method comprising:
-
heating a coating so that the coating is in a flowable state; applying a measured amount of the coating to reservoirs cooperatively defined by a expandable and collapsible structure and a guard that is bonded to an outer surface of the expandable and collapsible structure; and cooling the coating so that the coating is in a non-flowable state. - View Dependent Claims (32, 33, 34, 35, 36)

37. A method of applying a coating to a catheter assembly, the method comprising:
-
applying a coating to an exterior surface of a guard that is affixed to an expandable and collapsible structure of a catheter assembly, wherein the guard and the expandable and collapsible structure define a plurality of reservoirs having openings at the exterior surface of the guard; placing the guard and expandable and collapsible structure in an inner bore of a sheath; heating the coating so that the coating is in a flowable state; and sliding the guard and expandable and collapsible structure out of the sheath so that coating on the exterior surface of the guard is substantially removed. - View Dependent Claims (38, 39, 40)
