Cardiac implant and methods
First Claim
1. A cardiac implant comprising:
- (a) a scaffold defining an open interior volume, an open first end, and an opposite open second end;
(i) said open interior volume comprising a blood flow conduit to direct blood flow through the scaffold including through the open first end and the open second end;
(ii) said scaffold having an exterior surface and an opposite, interior surface;
(A) said interior surface lining said open, interior volume;
(b) a first therapeutic agent in at least partial covering relation to at least a first portion of one of said exterior surface and said interior surface; and
(c) a second therapeutic agent, different from said first therapeutic agent, in at least partial covering relation to at least a second portion of one of said exterior surface and said interior surface,wherein said first therapeutic agent is not in covering relation to the second portion.

Abstract
Cardiac implants include a conduit or scaffold having a first therapeutic agent in at least partial covering relation to at least a first portion of the scaffold, and a second therapeutic agent, different from the first therapeutic agent, in at least partial covering relation to at least a second portion of the scaffold. The first therapeutic agent and second therapeutic agent may include one of: antithrombotic agents, anti-inflammatory agents, antiproliferative agents, antibiotic agents, angiogenic agents, antiplatelet agents, anticoagulant agents, rhestenosis preventing agents, hormones and combinations thereof. Methods for making cardiac implants include providing a scaffold, covering at least a first portion of the scaffold with a first therapeutic agent, and covering at least a second portion of the scaffold, different from the first portion, with a second therapeutic agent different from the first therapeutic agent. Methods for treating a patient and for using cardiac implants include forming a blood flow path from a heart chamber directly to the coronary vessel, which includes placing a conduit in a heart wall between the chamber and the vessel with the first end of the conduit protruding into the chamber and protruding beyond an interior surface of the heart wall. The conduit will include a first therapeutic agent in covering relation to at least a first portion of the conduit and a second therapeutic agent in covering relation to at least a second portion.

31. A method for making a cardiac implant for establishing a blood flow path through a myocardium between a heart chamber and a lumen of a coronary vessel residing at an exterior of the myocardium;
- the method comprising;
(a) providing a scaffold defining an open interior volume, an open first end, and an opposite open second end; (b) covering at least a first portion of the scaffold with a first therapeutic agent, and (c) covering at least a second portion of the scaffold with a second therapeutic agent, different from the first therapeutic agent, wherein said first therapeutic agent does not cover the second portion. - View Dependent Claims (32, 33, 34, 35, 36, 37)

38. A method for performing a coronary vessel bypass procedure for supplementing a flow of blood to a coronary vessel;
- the method comprising;
(a) forming a blood flow path from a heart chamber directly to the coronary vessel at a site in the vessel positioned between an obstruction in the vessel and tissue of the heart to be supplied with blood by the vessel; (i) the forming including placing a conduit in a heart wall between the chamber and the vessel with a first end of the conduit protruding into the chamber and protruding beyond an interior surface of the heart wall; (ii) the conduit including a first therapeutic agent in covering relation to at least a first portion and a second therapeutic agent in covering relation to at least a second portion, wherein the first therapeutic agent is not in covering relation to the second portion.
