A tumor ablation device is an example of an image-guided device

 

Tumor ablation is one example of an image-guided technology that has developed into a potent tool for the definitive treatment of some benign and malignant tumors of the lungs, liver, kidneys, bone, and soft tissues as well as for pain relief over the past 20 years. Tumor Ablation Devices are one of the minimally invasive techniques used to eliminate cancerous cells from the patient's liver, chest, and other organs. The main contributor to the rise in cancer cases is the change in lifestyle, bad eating patterns, and increased use of alcohol and tobacco.

A technique that is increasingly used to treat localized cancer is image-guided tumor ablation. Thermal ablation and chemical ablation are the two main subcategories of tumor ablation. The authors provide an overview of the current techniques for thermal and chemical Tumor Ablation Devices, addressing the fundamental science behind these techniques as well as briefly summarising the commercial devices currently on the market in the United States. Tissue ablation has been used in some capacity in the field of medicine for more than a century1, but its use has increased in recent years.

Focused Tumor Ablation Devices have been used with both chemical and thermal techniques. Both of these treatments take the use of different physical, chemical, and metabolic characteristics of tumors to trigger local cell necrosis, despite the fact that procedure indications, patient selection criteria, and methodologies vary between them. Thermal ablation directly changes the lesion's local temperature by heating or chilling it, which results in either direct or indirect cell death. While cryoablation therapy uses rapid chilling cycles to destroy tissue, radiofrequency ablation (RFA), microwave ablation, laser ablation, and high-intensity focused ultrasound (HIFU) use heat to affect cell death. Chemical ablative agents, on the other hand, such as pure ethanol, rely on direct toxicity to cause necrosis.
