Focal Therapy

with Fusion-Guided
Laser Ablation

Precise Treatment. Precise Results.

Focal laser ablation provides a minimally invasive treatment that targets and ablates (destroys) only specific parts of glands, organs, or other tissue needing treatment, while preserving the surrounding and remaining tissue. This generally produces faster recovery, fewer side effects, and less pain and discomfort for patients that may not be good candidates or are inoperable for traditional open surgery*.

About CLS

CLS AB is an innovative medical device company within healthcare technology and therapy. With people in mind, we are at the forefront of developing more precise, more effective interventional healthcare solutions. 

Our TRANBERG™ systems marketed in the US by CLS Americas provide minimally invasive alternatives to traditional treatments and are FDA 510(k) cleared.

Focal therapy using TRANBERG™ Thermal Therapy System

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, saving healthy tissue.

Patient Focused

  • Minimally invasive outpatient procedure.
  • Performed in office, ASC, or hospital.
  • Low risk of complications.
  • Reduced risk of erectile dysfunction and urinary incontinence.
  • Quick procedure – quick recovery. 

A precisely controlled, image-guided laser ablation system for successful Focal Therapy

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 the TRANBERG™ Thermal Therapy System for image-guided focal laser ablation.

  • Precise positioning of the laser applicator in the defined target area using image-guidance.
  • Accurate temperature monitoring and control.
  • Option to choose between transperineal and transrectal pathway access.
  • Targeted tissue destruction.
  • Surrounding, non-cancerous tissue is spared.

How it all started

Through research by our co-founder, professor Karl-Göran Tranberg, CLS has gained significant knowledge and experience with treating/killing cancer tumors using laser ablation under image guidance. 

Today, our TRANBERG™ Thermal Therapy System is optimized for minimally invasive focal therapy of soft tissue and used to treat patients with localized prostate cancer.
