Precision in Practice

Using Minimally Invasive Laser Ablation

Aiming for the precise

The challenges in healthcare are many. At CLS we are committed to developing better therapies for use in cancer care and neurosurgery. We do this by providing tools for precise tissue ablation using heat generated by laser light. Our close collaboration with healthcare professionals ensures our products meet their requirements and seamlessly fits into hospital workflows. This enables more patients to be treated based on their specific diagnosis and needs. Carefully precise.

Focal therapy in localized prostate cancer

Focal therapy using laser ablation is a growing treatment option for patients with prostate cancer. It is an effective method that treats the tumor locally without damaging healthy tissue. The procedure is minimally invasive and thus gentle on the patient, who typically can return quickly to normal life. 


Careful therapy of brain lesions

A tumor or epileptogenic foci in the brain means major challenges – for the patient and for healthcare. When using laser ablation in neurosurgery the lesion is directly targeted and treated with high precision. The treatment spares healthy tissue and causes less side effects than surgery and chemotherapy.

Immune stimulating laser ablation – using new hot technology

The thermal effects on cells depend mainly on two factors – temperature and time. Research has shown that moderate heating of cancerous tumor cells during a long time will not only kill the targeted tumor itself, but also activate the immune system to attack cancer cells throughout the body.

Integrated therapy systems for high precision laser ablation

Our driving force is to design and develop tools for treatment of severe diseases, such as cancer, in a precise and careful way. It is from this perspective we have developed CLS TRANBERG® Thermal Therapy Systems – seamlessly integrated systems for laser ablation, with several options for real time monitoring and control of the treatment.
