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.
