New Dialysis Catheter Reduces Thrombus Accumulation03/16/2010
MAPLE GROVE, Minn.—r4 Vascular has released its new Duraspan Biomimetic Coated long-term hemodialysis catheter, which has a coating on the catheter surface that mimics the glycocalyx layer found on natural endothelial tissue surfaces in vessel walls.
Laboratory tests of the Duraspan catheter have demonstrated an 87 percent reduction in platelet adhesion and thrombus accumulation compared to uncoated catheters, according to r4 Vascular.
Thrombus accumulation is one of the leading causes of failure among long-term hemodialysis catheters,” said Kyle Smith, DO, who is with Vascular Access Center of Southwest Louisiana “Initially, thrombus may cause reduced flow rates, significantly decreasing the efficiency of even the largest catheters. Ultimately, thrombus may have catastrophic effects to the patient as it may prevent use of the venous access site for permanent forms of dialysis.”
Studies have shown almost 30 percent of prevalent hemodialysis patients use catheters for vascular access. Catheter complications are a major cause of morbidity and mortality for hemodialysis patients and increase the burden on the healthcare system. Surface treated catheters have been developed to combat the three most common causes of catheter failure: infection, fibrin sheath formation and thrombus formation. Thrombotic reducing coatings reduce platelet adhesion, inhibit the inflammatory response, and reduce thrombus formation on coronary stents, ventricular assist devices, central venous catheters, and vascular grafts.
R4 will be “launching” sales of the catheter at the S.I.R. (Society of Interventional Radiology) conference March 13 through March 18 in Tampa, Fla..
