Abstract:
A device for delivering a therapeutic solution from a solution supply into cardiac tissue, the device comprising:a hollow needle having a needle proximal end and a needle distal end, said needle proximal end being adapted for fluid attachment to said solution supply, said needle comprising an elongated flexible body, and a sharpened tip disposed at said needle distal end for penetration of cardiac tissue, a steering cable having a cable distal end secured to the hollow needle at a coupling, said coupling being spaced from the distal end of the hollow needle, said steering cable extending toward the proximal end of the hollow needle and having a cable proximal end, said steering cable being manipulable to flex the needle distal end relative to the needle proximal end along a flexion radius when a tensioning force is applied to the cable proximal end, and a steering sleeve movable disposed about the elongated flexible body and said steering cable such that a distance between the steering sleeve and said coupling determines the flexion radius and whereby movement of the steering sleeve along the hollow needle adjust the flexion radius.
