Catheter device for repositioning or explanting an implantable medical device

A method for operating a catheter device for repositioning or explanting an implantable medical device, comprising:

• providing a catheter device comprising:
• a non-steerable outer catheter and a steerable catheter extending through the non-steerable outer catheter, wherein the non-steerable outer catheter is axially movable with respect to the steerable catheter;
• a handle piece comprising a control device having a steering mechanism comprising a rotatable wheel for directly controlling a deflection of the steerable catheter, the handle piece further comprising a lock mechanism for axially locking the snare catheter with respect to the steerable catheter,
• establishing a connection to the implantable medical device using a snare catheter extending through the steerable catheter, a mandrel extending through the snare catheter and comprising a distal end, and a snare arranged on the distal end of the mandrel,
• wherein said establishing the connection includes axially moving the snare catheter relative to the steerable catheter, axially moving the mandrel relative to the snare catheter, and retracting the snare, by moving the mandrel with respect to the snare catheter, at least partially into the snare catheter.
