Electrothermal Cautery Units, HIgh-Resistance, Transcatheter, Angioplasty
Definition : Electrothermal cautery units designed to coagulate and/or destroy tissue by applying an electric current to a high-resistance element to perform angioplasty through a catheter that is percutaneously inserted into the blood vessels (e.g., arteries). These units typically consist of a power source (e.g., radiofrequency or microwave generator) that delivers the electric current, appropriate controls, a catheter, and appropriate connectors and/or adapters to attach the catheter to the unit. Electrothermal cautery units do not deliver electric current to the tissues; the high-resistance tip becomes heated when an electric current is passed through it. The unit usually controls temperature and energy delivery automatically. Angioplasty electrothermal cautery units can be used to eliminate areas of narrowing in blood vessels by performing thermal compression and ablation of atheromatous plaque; they are used mainly to open total occlusions or high-grade stenoses in peripheral arteries.
