Abstract:
A percutaneous drug delivery catheter comprising:a catheter jacket, having proximal and distal ends, and at least a first lumen;at least a first drug delivery device within the first lumen of the catheter jacket, the first drug delivery device having proximal and distal ends;a deflection mechanism at the proximal end of the catheter, the deflection mechanism operatively attached to a deflector device at the distal end of the catheter jacket, the deflection mechanism comprising a groove portion on a deflection actuator which cooperates with a set of thread pins attached to a rotatable inner deflection knob coupled to the catheter jacket, activation of the deflector device by movement of the deflection mechanism deflects the distal end of the catheter jacket and the drug delivery device therein; anda relative movement compensation mechanism operatively attached to the deflection mechanism and the proximal end of the first drug delivery device, the relative movement compensation mechanism comprising a thread portion on a handle which cooperates with a groove portion on the inner deflection knob,wherein, during movement of the deflection mechanism, simultaneous movement of the relative movement compensation mechanism occurs whereby the alignment between the distal end of the catheter jacket and the distal end of the first drug delivery device is maintained during the deflection.
