Thermal response and ablation characteristics of light weight ceramic ablators
28th Thermophysics Conference, 1993An account is given of the thermal performance and ablation characteristics of the NASA-Ames Lightweight Ceramic Ablators (LCAs) in supersonic, high-enthalpy convective environments, which use low density ceramic or carbon fiber matrices as substrates for main structural support, with organic resin fillers.

Radiofrequency Thermal Ablation
2007Over the last decade, radiofrequency thermal ablation (RFA) has become an accepted treatment modality for unresectable primary and metastatic liver tumors. It can be performed either percutaneously, laparoscopically, or via an open approach. With experience, indications and selection criteria have been determined for each tumor type. RFA has become the

Imaging appearances following thermal ablation
Clinical Radiology, 2008Radiofrequency ablation (RFA) has an increasingly important role in the management of a number of solid tumours. Treatments usually take place at specialist centres that draw patients from a wide geographical area, but follow-up imaging is often undertaken at the referring institution. This review aims to describe and illustrate the range of normal and

Recanalization After Endovenous Thermal Ablation
Annals of Vascular Surgery, 2018Endovenous thermal ablation in the form of radiofrequency ablation (RFA) or endovenous laser ablation (EVLA) has quickly ascended to a prime position in the treatment of venous insufficiency. Although there are good data examining the rates of thrombotic complications, there is a relative paucity of data examining the recanalization rates after ...

Thermal endometrial ablation: a simple technique
Acta Obstetricia et Gynecologica Scandinavica, 2000Background. To evaluate the effectiveness and safety of a technique for thermal endometrial ablation.Method. The study was carried out in three steps; step I on 10 fresh uterine specimens, step II on 14 intact uteri during hysterectomy and step III in five patients, two weeks prior to hysterectomy. A simple device comprising a Foley catheter No. 14F, a

Man constantly strives for excellence and perfection. Patients with varicose veins can seldom be offered a complete cure. The aim of treatment is adequate control of the disease process. Chronic venous disorders can be controlled by conservative measures or by the use of interventions.

Principles of Thermal Ablation
2017Within the field of local–regional hepatic therapies, the area of thermal ablation plays an important role. First conceptualized in the 1840s, thermal ablation greatly expanded after the advent of cross-sectional imaging. These techniques are generally used for patients with unresectable and borderline resectable disease, which may be due to the size ...

Overview of Thermal Ablation Devices: Radiofrequency Ablation
2012“Thermal ablation” is de fi ned as the application of heating agents to a specific area of the body with the intention of tissue destruction. The deleterious effect of heat is based on the fact that when biological tissues reach a temperature above 45°C, irreversible cell damage occurs.

Prior to the introduction of endovenous ablation, surgery was considered the only effective treatment option for venous insufficiency caused by saphenous venous reflux. Lack of patient acceptance and discouragingly high rates of varicose vein recurrence have led to efforts to find less traumatic, more cost-effective, and more successful methods of ...
