Multiple drug delivery from a balloon and a prosthesis
First Claim
1. A system for delivering beneficial agents, comprising:
- a balloon having an outer surface, at least a portion of the outer surface of the balloon having a continuous coating of a therapeutically effective amount of a first beneficial agent; and
a prosthesis that can be delivered or implanted having a surface that is at least partially coated with a therapeutically effective amount of a second beneficial agent,wherein the first beneficial agent is different from the second beneficial agent with respect to hydrophobicity and at least the coating of the first beneficial agent has a varied local areal density as a measure of beneficial agent per unit local surface area, and wherein the system is useful for the treatment and prevention of a vascular disease.

Abstract
Disclosed is an interventional device for delivery of therapeutic agents from an angioplasty balloon and from a prosthesis such as an intraluminal stent. The invention also relates to the method of loading the beneficial agents onto the balloon and the device, as well as the method of delivery of the agents from separate surfaces. The invention also relates to an interventional device having a prosthesis surface that is loaded with a first beneficial agent, and a balloon surface loaded with a second beneficial agent. The invention also relates to a method of loading multiple beneficial agents onto the prosthesis surfaces and the balloon surfaces, and to a method of manufacturing an interventional device for the delivery of a first beneficial agent and a second beneficial agent from separate surfaces.

31. A system for delivering beneficial agents, comprising:
-
a balloon having an outer surface, at least a portion of the outer surface of the balloon having a continuous coating of a therapeutically effective amount of a first beneficial agent, the continuous coating comprising a first carrier adapted to release the first beneficial agent at a first release rate; and a prosthesis capable of being implanted, the prosthesis including a coating containing a second carrier adapted to release a therapeutically effective amount of a second beneficial agent at a second release rate different from the first release rate, wherein at least the first beneficial agent has a varied local areal density as a measure of beneficial agent per unit local surface area. - View Dependent Claims (32, 33, 34, 35)

36. A system for delivering beneficial agents, comprising:
-
a balloon including a plurality of balloon areas covered by a continuous first coating of a therapeutically effective amount of a first beneficial agent, the plurality of balloon areas having local areal densities of the first continuous coating that are different from each other; and a prosthesis capable of being implanted, the prosthesis including a plurality of prosthesis areas covered by a second coating containing a therapeutically effective amount of a second beneficial agent, the plurality of prosthesis areas having local areal densities of the second coating that are different from each other, wherein areal density is amount of beneficial agent per unit local surface area. - View Dependent Claims (37, 38, 39)
