The company said that Evolution requires less surgical finesse and is more intuitive to use than laser-powered systems. It is also designed to negotiate chronic heavily fibrosed and calcified lesions more rapidly and effectively than powered sheaths utilizing forward depth of tissue disruption.
Barry Norlander, global marketing manager for Cook Vascular, said: “We’ve designed Evolution to be an extremely attractive alternative to current lead extraction technology. Current laser extraction requires a stand alone unit that weighs over 275kg to power the device.
“Additionally, laser sheaths need calibrating before each operation. Evolution needs no additional capital equipment nor annual maintenance contracts and inspections. No electricity is required, neither is an on-site laser technician, it’s a viable alternative, both from an operation and fiscal efficiency perspective. With Evolution we hope to minimize the risk of vascular perforations seen with laser-powered extraction.”
