Blocked Arteries Helped by the Crosser
Blockages in arteries are a cause of great concern. When an artery becomes totally obstructed it is called a "Chronic Total Occlusion". They can be found in patients with heart disease triggering chest pain and angina. Or they can occur in the legs and in some cases lead to amputation if blood flow is impaired.
Patients may be treated with medication or bypass surgery. Another treatment involves inserting a wire into the artery and pushing it slowly through the blockage, but the wire may tear the artery accidentally.
Researchers, however, have been conducting trials on a new exciting method to treat blocked arteries. A tiny vibrating device, less than one millimetre wide, that acts like a mini pneumatic drill, produces vibrations that break apart the blockage in the artery, allowing them to be flushed out of the bloodstream. The tool, called the "Crosser Catheter," helped patients trials that had not responded to other treatments.
The high-frequency vibration of the tool creates mirco-bubbles in the surrounding fluid of blood and saline. These bubbles expand and implode producing liquid jets that help to chip away at the surface. One study from the University of Catania, Italy, used the device on 46 patients, with 39 being treated successfully. These results are very encouraging. The manufacturers reported that if further tests were successful, the device would become more widely available. We hope the findings will support further distribution, so many can be saved from much pain and agony.
