The introducer system features a clear sheath for enhanced visualization, as well as ink markings on the delivery system to improve placement of the stent pigtail.

The ink markings are used as a reference to assist in both the first and second pigtail deployment for all stent sizes to ensure accurate placement.

The Resonance Metallic Ureteral Stent coil design allows urine to flow even in instances of extreme compression.

It is introduced coaxially through a clear sheath and removed using cystoscopy techniques.

A retrospective analysis conducted during 2009 showed that the Resonance Metallic Ureteral Stent remains in patients up to 12 months, giving a 43% cost savings in treating benign upper ureteral obstruction.

Cook Medical Urology Business Unit leader Jean-Marc Creissel said the updated Resonance Metallic Ureteral Stent System will have a positive impact on physician use as a result of the ease of placement and visualization.
