Cook Medical has announced some improvements to its Resonance Metallic Ureteral Stent System.
First launched in 2007, the device now has an updated introducer system that includes a clear sheath for enhanced visualization, as well as ink markings on the delivery system to improve placement of the stent pigtail. The system provides ink markings as a reference to aid in both the first and second pigtail deployment for all stent sizes to ensure accurate placement.
In 2009, the results of a 13-patient, single-site retrospective analysis showed that the Resonance Metallic Ureteral Stent could remain in patients up to 12 months, generating a 43 percent cost savings in treating benign upper ureteral obstruction. These cost savings resulted from the reduction in stent changes required with the Resonance stent compared to standard plastic stents.
The Resonance Metallic Ureteral Stent is introduced coaxially through a clear sheath and removed using standard cystoscopy techniques. The unique coil design allows urine to flow even in instances of extreme compression.
