A steerable catheter (310) having a handle, a manifold strain relief (314) securely mounted at a front distal end of the handle, a steering dial (316) rotatably mounted within the handle, the steering dial (316) comprises a steering dial left fastener (316L) and a steering dial right fastener (316R). A lumen extrusion shaft (318) is securely fastened at a rear distal end to the manifold strain relief(314). The lumen extrusion shaft (318) has at least one lumen extrusion shaft large lumen opening (318B) and at least one lumen extrusion shaft small lumen opening (318C) contained therein. A lumen extrusion tip (320) is securely fastened at a front distal end of the lumen extrusion shaft (318) by a lumen extrusion shaft connection (318A). A manifold (334) is securely fastened at a rear end of the manifold strain relief (314). At least one luer lock (324) is securely mounted at a rear distal end of the handle. A steering wire (328) securely fastened at a rear distal end to the steering dial (316). The steering wire (328) is slidably mounted within the manifold (334) and the manifold strain relief (314) and the lumen extrusion shaft (318). The steering wire (328) has a left steering wire (328L) securely fastened at a rear distal end to the steering dial left fastener (316L) and a right steering wire (328R) securely fastened at a rear distal end to the steering dial right fastener (316R). The steering wire (328) is slidably positioned within the at least one lumen extrusion shaft small lumen opening (318C). The steering wire (328) is securely affixed at a front end to the lumen extrusion shaft (318) by a lumen extrusion shaft small lumen attachment (318CA). The steering wire (328) terminates at a front distal end wire flat lumen extrusion tip which is securely mounted within the lumen extrusion tip (320). A catheter body lumen tubing (330) securely fastened at a rear distal end to the least one luer lock (324) and is securely fastened at a front distal end to the at least one lumen extrusion shaft large lumen opening (318B). A front end of the catheter body lumen tubing (330) is securely mounted within the manifold (334).
