<p>Material may be implanted or injected into cardiac veins as discrete masses for treating various cardiac conditions. A catheter suitable for delivering occluding agent into the cardiac venous system the heart includes a distal end that is positionable within a cardiac vein at a location where an occlusion is to be established. A barrier is provided for occluding the vein adjacent the barrier. A lumen (more than one lumen may be provided if desired) is disposed within the catheter tube and passes through the barrier to terminate at an aperture (more than one aperture may be provided if desired) distal of the barrier, for delivering the occluding agent into the vein beyond the barrier. An inner tube may be provided for introducing an occluder into the vein and spaced away from the barrier, for defining a vein segment between the barrier and the occluder. Methods and kits are also contemplated.</p> |
