Patent ID: 7914517

Claim:
A system for manipulating a catheter used for delivering a substance to a body cavity of a patient, the system comprising: a catheter comprising at least one lumen or tube, the catheter having a proximal end configured for receiving a substance intended for delivery to a body cavity and a distal end comprising a flexible tip biased in a pre-shaped curve; and an introducer apparatus comprising: a body defining a bore sized to receive the catheter; a catheter adjustment mechanism having a rotatable knob that is rotatably attached to the body and offset from the catheter, the catheter adjustment mechanism configured to rotate the catheter relative to the body of the introducer apparatus about a longitudinal axis of the catheter via rotation of the rotatable knob, wherein the catheter is axially movable relative to the rotatable knob; wherein the catheter adjustment mechanism is operably connected to the catheter to simultaneously control both axial and rotational orientation of the catheter relative to the body of the introducer apparatus; and wherein the catheter adjustment mechanism further comprises: a first gear arrangement operably connected with the rotatable knob and configured to rotate the catheter relative to the body in response to rotation of the rotatable knob; and a second gear arrangement operably connected with the rotatable knob and configured to move the catheter longitudinally relative to the body in response to rotation of the rotatable knob simultaneously with rotation of the catheter.
