Catheter with locking device

摘要

A catheter with a locking device is formed of a catheter and a locking device attached to a proximal end of the catheter. The locking device is formed of a cylindrical portion fixed to the proximal end of the catheter and having a dent at one side thereof, and a movable ring rotatably attached to the cylindrical portion and having a slit. The movable ring is rotatable to open and close the dent, so that when a portion of the catheter is placed in the dent through the slit, the movable ring is rotated to close the dent to securely hold the portion of the catheter in the slot. Accordingly, the catheter can be locked in the looped condition.
