ABSTRACT:
A controller for moving an elongated medical instrument in a catheter comprising a supporting structure including a mounting section adapted to be coupled to a catheter and a drive section. The controller also includes a drive wheel and a secondary wheel with each of the wheels having a peripheral surface. Each of the peripheral surfaces has an instrument groove portion. One of the wheels has a circumferential recess in its peripheral surface and the other of the wheels provides a circumferential projection. The wheels are rotatably mounted on the drive section with the peripheral surfaces in generally confronting relationship and with the projection in the recess to align the wheels and to maintain the wheels in alignment as the wheels rotate. The instrument groove portions are in confronting relationship to provide an instrument groove which is sized and adapted to receive an elongated medical instrument.
