Which Interventional Device - expert independent opinion of interventional devices

The locking device works well but is difficult to release. We tend to cut the catheter at the hub when we want to remove it making sure that the thread also pulls free. Another point to note is that you cannot aspirate from it until it is locked as air is sucked up into the syringe via the locking mechanism. This also seems to be a problem with other locking mechanisms (Uresil).

I use both catheters (from Boston and Cook). In my experience, the Mac-Loc catheter slides easier along the track, the 0.018 guidewire (included in the set) doesn't kink, but the locking arm is quite hard to be pushed down. The major disadvantage of Boston's nephrostomy set is that the dilator can be easier teared on the tip while passing through tissues. On the other hand, the Chiba needle included on Boston's set is better visualized on ultrasound than the one of Cook's set.
