The STAR™ Tumor Ablation System is indicated for palliative treatment in spinal procedures by ablation of metastatic malignant lesions in a vertebral body.

Targeted therapy for fast, local control

The SpineSTAR Ablation Instrument is uniquely designed specifically for use in the complex anatomy of the spine. This small steerable device is inserted into the vertebra to deliver targeted RF energy to the tumor. RF energy heats and destroys metastatic tumor cells, while temperature sensors within the SpineSTAR continuously monitors the ablation zone progress to minimize patient risk. Additionally, the instrument is created with a coaxial lumen to facilitate biopsy or injection of cement if indicated without removing the cannula.

While any patient with focalized pain from a metastatic spinal tumor may be a candidate for t-RFA, several specific patient groups will likely benefit most from the procedure.

These include patients…

  • with radio-resistant tumors.
  • with recurrent pain after radiation therapy.
  • with posterior vertebral body metastatic tumors.
  • who have reached their maximum radiation dose limit.
  • with localized pain and symptoms that are preventing palliative radiation.
  • who cannot undergo other palliative treatments due to current systemic treatments.
  • in which myelosuppression is of concern.

Fast & Durable

Oncologists and cancer care team members recognize the fast and durable pain relief patients achieve with minimally invasive targeted radiofrequency ablation (t-RFA).

Single Treatment

Using the STAR Tumor Ablation System, t-RFA delivers meaningful pain relief and localized tumor destruction in a single treatment, often in an outpatient setting.


With the STAR System, physicians have the control to create site-specific ablation zones and monitor real-time ablation zone development within the vertebral body.


Compatible with systemic therapies, t-RFA expands the range of treatment options for patients with painful spinal tumours.

Meaningful Clinical Outcomes

Clinical data show that rapid and lasting pain relief from metastatic spinal tumors is a reality for patients who receive t-RFA using the STAR System. This multicenter retrospective study included 128 treated lesions in 92 patients, many of whom had failed radiation therapy. Pain was decreased by 77% and 54% of the patients were able to reduce pain medication usage after t-RFA.


 “The spine tumor ablation procedure is particulary helpful for those patients who have a type of tumor that is radiation therapy resistant. In these patients the local control for a tumor in the spine and the pain relief we can offer can be significant.”
