Abstract
A percutaneous epicardial injection apparatus for myocardial repair and treatment includes a catheter having a tubular wall, an interior portion surrounded by the tubular wall, a base end, a distal end, and a central longitudinal axis extending between the catheter base end and the catheter distal end. The catheter distal end has an end face that is formed at an oblique angle relative to the catheter longitudinal axis and adapted to attach to a patient's myocardium using suction. A lumen extends from the catheter base end to the catheter distal end within the catheter interior. The lumen is adapted to slidably support an elongated syringe having a needle tip adapted for movement between a retracted position wherein the needle tip is recessed within the catheter interior to an extended position wherein the needle tip extends from the catheter interior. The injection apparatus may be used to introduce a myocardial repair or treatment material into a dysfunctional area of the myocardium while the catheter distal end is attached thereto by extending the needle tip into the myocardium and injecting the myocardial repair or treatment material into the dysfunctional area.
