Injection Innovation
Combined benefits of fixed and rotating luer-lock designs

Control syringes are commonly used in angiographic procedures to inject viscous contrast media, medications, and saline.

There are two types of control syringes commonly used in angiographic procedures:

  • Fixed-Luer Syringes

  • Rotating-Luer Syringes

Fixed-luer syringes feature a solid, one-piece design that enables secure, leak-free connections, but connecting and disconnecting them from catheters and manifolds can be awkward.


Rotating-luer syringes are easier to connect and disconnect as a result of their O-ring design, but they are prone to loose, wobbly connections and air leakage, putting patients at risk of air embolism.

The patented AirTight Syringe with Slip-Ring Technology bridges the gap between fixed- and rotating-luer designs, offering easy connection and disconnection to catheters and manifolds without compromising patient safety.

Rotating Finger Loops

Loops freely rotate around barrel for fast, easy connection/disconnection and improved injection ergonomics.

Tight Fixed-Luer Connection

One-piece luer design locks for secure, air-tight, and wobble-free connection to catheters, manifolds, and other devices.
