MEDICAL DEVICE WITH THERAPEUTIC AGENTS
First Claim
1. A medical device for at least partial implantation, comprising:
- a main body having a length extending between a first end and a second end, the main body including a first tube at least partially positioned within a lumen of a second tube to form an annular space between an interior surface of the second tube and an exterior surface of the first tube, the first tube having a lumen extending from the first end to the second end;
a first section along the length of the main body proximal the first end of said main body and having a first therapeutic agent, said first therapeutic agent comprising one or more members selected from the group consisting of antiproliferatives, anticoagulants, antithrombotics, thrombolytics, and fibrinolytics; and
a second section along the length of the main body proximal the second end of said main body and having a second therapeutic agent, said second therapeutic agent comprising an antimicrobial.

Abstract
A medical device is adapted for at least partial implantation into a body and includes first and second sections along the length of the device. A first therapeutic agent is associated with the first section and a second therapeutic agent is associated with the second section. The first therapeutic agent can be one or more antiproliferative, such as paclitaxel, a paclitaxel derivative, or a paclitaxel pro-drug, anti-coagulant, antithrombotic, thrombolytic, fibrinolytic, or combination thereof. The second therapeutic agent can be one or more antimicrobials, such as one or more antibiotics. Each of the first and second therapeutic agents can either be posited on one or more surfaces of the respective section, or impregnated within the section. The device can include a separator to space the first and second sections. A method of making a medical device and a method of establishing access to a vessel within a body are also provided.

19. A method of establishing access to a vessel of the body, the method comprising
(a) implanting a distal portion of medical device within a body vessel with a proximal portion of the medical device outside the body vessel, the medical device including: - (i) a main body having a length extending between a first end and a second end, the main body including a first tube at least partially positioned within a lumen of a second tube to form an annular space between an interior surface of the second tube and an exterior surface of the first tube, the first tube having a lumen extending from the first end to the second end;
(ii) a first section along the length of the main body proximal the first end of said main body and having a first therapeutic agent, said first therapeutic agent comprising one or more members selected from the group consisting of antiproliferatives, anticoagulants, antithrombotics, thrombolytics, and fibrinolytics; and
(iii) a second section along the length of the main body proximal the second end of said main body and having a second therapeutic agent, said second therapeutic agent comprising an antimicrobial; and
(b) forming an interface between the distal end and the vessel to provide access to the vessel through the lumen of the first tube.
- (i) a main body having a length extending between a first end and a second end, the main body including a first tube at least partially positioned within a lumen of a second tube to form an annular space between an interior surface of the second tube and an exterior surface of the first tube, the first tube having a lumen extending from the first end to the second end;
-
20. A method of making a medical device for at least partial implantation within a body, the method comprising
(a) providing a main body having a first end, a second end, a length extending from the first end to the second end, a first section along the length, and a second section along the length; -
(b) exposing the first section to a solvent so that the first sections swells;
soaking the first section in a solution containing a first therapeutic agent;
drying the first section; and
(c) coating at least a portion of the second section with a second therapeutic agent.
