Most device loaders are almost exclusively made from Minnesota MedTec and are a unique offering to introduce odd shaped/non push-able items into catheters. Loaders are used with catheters when a device such as an expandable NiTi device must be pushed through a catheter and expand when it exits the tip.

The present designs come with push (snap) or rotation connectors that attach to specially designed sheaths. The loaders distal end mates up into the sheaths hub for a smooth inside diameter transition from the loader to the sheath and allows for an easy device transfer.
