Radiofrequency Device Opens Stubborn Chronic Venous Occlusions
A new device provides relief to patients with swollen arms and legs as a result of their medical conditions, such as those who are on dialysis for kidney failure, or who have pacemakers. These patients have permanent devices in their veins, which can causes scarring and reduce blood flow, leading to swollen extremities. Doctors use a variety of techniques to open up the completely blocked veins (called a central venous occlusion, or CVO), but efforts fail 10 to 12 percent of the time, and those patients are miserable because their extremities are very swollen. The new device, the Baylis PowerWire™ Radiofrequency (RF) Guidewire, is advanced to the site of the scarring using minimally invasive techniques. RF energy is used to burn through the blockage.
