Dredger™ Supporting Catheter

The Dredger™ Supporting Catheter is designed to provide robust support and precise lesion navigation in peripheral arterial procedures, especially those involving arteriosclerosis obliterans. Key features include:

• Dual‑tapered tip with an ultrafine profile for easier lesion penetration and improved guidewire seating.

• Triple radiopaque markers plus a highly visible polymer tip to ensure accurate positioning and lesion length estimation under fluoroscopy.

• Double flat‑wire braided shaft provides superior support, torque transmission, and resistance to kinking.

• Four pre‑shaped curve options help accommodate varied vessel anatomies and improve control during guidewire manipulation.

Available in a variety of guidewire compatibility options (0.014″, 0.018″, 0.035″) with matching distal/proximal diameters and effective lengths around 65–170 cm across straight and 17°, 30°, and 45° curves. Certain versions are coaxially compatible between sizes to streamline device pairing in complex peripheral interventions.

• NEW: double-sided, dual diaphragm chestpiece for both adult and paediatric assessment.
• NEW: The paediatric side is also easily transformed into a traditional open bell by replacing the single-piece diaphragm with the supplied non-chill rim.
• NEW: chestpiece is precision-machined into an aesthetically pleasing, less angular shape.
• NEW: single-piece diaphragm instead of separate diaphragm/rim making it easier to attach and easier to clean due to the smooth unbroken surface.
• NEW: The stem features an open side indicator to easily identify which diaphragm is in operation.
• NEW: next-generation tubing gives even longer tube life with improved resistance to skin oils, alcohol and staining.
• 3M’s ‘Tunable Technology’ lets you easily switch from low to high frequency sounds by switching from light to firm pressure on both the adult and paediatric sides of the chestpiece.
• High acoustic sensitivity when performing general physical assessment.
• Laser engraving of text and symbols to personalise your scope and avoid theft/loss
• Larger ear tubes on the anatomically designed headset comfortably positioned for better sound transfer. Easy adjustment by simply squeezing or pulling apart the eartubes.
• Comfortable Snap-Tight soft seal eartips create an excellent acoustic seal to reduce ambient noise.
• No natural rubber latex or phthalate plasticisers are used in the tubing or any other component—to help protect health and the environment.
