Thermal ablation probe for minimal invasive body tissue high frequency thermal treatment has temperature sensor on star shaped flexible arms with adjustable protrusion from insulating sheath

摘要

A thermal ablation probe (14) has a temperature sensor (28) on the end and metal electrodes (16) for high frequency power application with star shaped flexible arms (26) having a spiral, zigzag or meander central section (M) adjusted and retracted by a flexible adjuster (36) and protruding from an insulating sheath (18). Includes Independent claims for the manufacture of the prove using microslitting of the tube (32).
