Abstract
The present invention provides systems and methods for locking and detecting the presence of a catheter. In an embodiment, a catheter system comprises a catheter and a magnet attached to a proximal end of the catheter. The catheter system further comprises a lock receptacle configured to receive and lock the proximal end of the catheter therein, and a Hall-effect sensor configured to detect the presence of the magnet, and hence the catheter, when the catheter is locked in the lock receptacle.

15. A system comprising:
-
a catheter system comprising an elongated catheter body having a proximal end, an imaging transducer disposed in the catheter body, a lock receptacle configured to receive and lock the proximal end of the catheter therein; a magnet disposed on a portion of the catheter system; and a Hall-effect sensor disposed on a portion of the catheter system; wherein the catheter system is configured and arranged so that locking the proximal end of the catheter in the lock receptacle aligns the magnet with the Hall-effect sensor; a motor drive unit coupled to the catheter system; and a processing unit coupled to the catheter system and configured and arranged for receiving signals from the imaging transducer. - View Dependent Claims (16)
