Abstract
Disclosed is an implantable device with enhanced drug delivery area, wherein a pre-crimped stent assembly mounted on a balloon further comprises a homogenous coating of drug and associated polymeric matrix resulting in the formation of a circumferential cylindrical film formation, upon expansion of the balloon. The cylindrical film formation by the drug delivery medical devices enables maximum coverage area of the vascular lumen area, thereby preventing any untreated area within a lumen.

1-11. (canceled)
A method of coating a stent comprising:
- crimping a stent assembly on a balloon assembly to form a pre-crimped stent mounted on a balloon, the stent assembly comprising a plurality of strut components with a plurality of interconnected space regions defined within the plurality of strut components;
- and
- covering an outer surface of the pre-crimped stent mounted on the balloon with a coating, wherein a plurality of sections of the balloon assembly are exposed to the coating, forming a homogenous cylindrical coating.
An apparatus comprising:
- a pre-crimped stent mounted on a balloon;
- and
- a coating surrounding the pre-crimped stent mounted on the balloon, wherein the coating comprises a homogenous cylindrical coating of a matrix of one or more drugs and one or more polymers, and wherein the coating covers a circumferential area of a vascular body lumen on expansion of the balloon.
A system comprising:
- a balloon insertable into a blood vessel, wherein the balloon is configured to expand and contact inner walls of the blood vessel;
- a stent coupled to the balloon;
- and
- a coating surrounding the stent and the balloon, wherein the coating comprises one or more drugs and one or more polymers.
