The Ark utilizes 3D technology to create a porous device made from titanium alloy, designed to:
The Ark is not a one-size-fits-all. It comes in multiple sizes to accommodate patients with different medical needs. Surgeons determine which Ark to recommend to patients.
While the Ark comes in different diameters, the access window is the same for all models. The Ark’s length remains three centimeters, allowing cannulators to have the same cannulation experience when performing various cannulation methods, including the Rope Ladder technique.
Complications from multiple and deep needle infiltration can cause damage to the fistula during cannulation. The more times the vein is poked with a needle, the weaker it gets.
