Memokath™

Memokath™ is a unique range of biocompatible nickel-titanium stents used to safely counteract urinary tract obstructions. Learn more about Memokath™ and each product group below.

What is Memokath™?

Memokath™ is a urological stent produced in advanced nickel-titanium alloy with memory-shape effect, developed with the aim of providing free flow of urine through obstructions in the urinary system. Memokath™ stents have a tight spiral structure which allow it to conform and adapt to the natural curves of the urinary tract, while making tissue in-growth between the coils difficult. The Memokath™ range consists of five different product groups each customized to treat obstructions in their respective areas of the urinary system.

How does Memokath™ work?

Memokath™ is inserted unexpanded into the desired location in the urinary system. Once positioned correctly across the stricture, sterile water above 55°C is flushed through the system, allowing the advanced nickel-titanium formula to expand either one, or both ends of the coil. The expansions act as anchors keeping Memokath™ safely in place, allowing urine to flow freely. When exchange of Memokath™ is desired, sterile water below 7°C is flushed through the system softening the coils whereby Memokath™ can be removed as easily as it was inserted.

Memokath™ – a new generation of easily removable stents

Unlike early examples of urological metallic stents, Memokath™ is easily removable due to its advanced NiTinol-formula, and can safely be exchanged, or removed altogether even after years insitu.
