Abstract:
A guidewire deflection system comprising:a catheter body having a proximal end, a distal end, a longitudinal axis, and at least one lumen extending along the catheter body; a nosecone formed at the distal end of the catheter body having a distal opening in communication with the catheter body lumen, a lateral opening spaced relatively proximal to the distal opening that is in communication with the catheter body lumen, and an inclined surface formed proximally adjacent to the lateral opening; and a cannula having a proximal end, a distal end, and at least one passageway extending through at least a distal portion of the cannula, wherein the distal end of the cannula is configured to deflect away from the longitudinal axis of the catheter body when the distal end thereof engages the inclined surface adjacent to the lateral opening, wherein the guidewire deflection system is configured for use in coronary vasculature.
