This is a technical overview of an INVAMED device within the oncology ablation portfolio. Because ablation is a local therapy, tumor size, number, location relative to vessels and organs, and overall clinical status all influence whether it is appropriate, as determined by a multidisciplinary clinician team. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Percutaneous Tumor Ablation
RFA has an extensive track record in hepatocellular carcinoma (HCC), MWA is frequently applied to liver and lung tumors, and cryoablation is often described for renal cell carcinoma, though indications are always defined by the treating team. Percutaneous tumor ablation is a group of minimally invasive techniques in which energy is delivered through a needle-like applicator, placed through the skin under imaging guidance, to destroy a focal tumor in situ. Beyond needle-based approaches, focused laser energy delivered through endoscopic instruments can be used trans-urethrally to vaporize or coagulate bladder tumors and to treat benign prostatic hyperplasia (BPH) with the aim of limiting bleeding.
Fusion Intraosseous Radiofrequency Ablation System for Spinal Tumors: Overview
Intraosseous radiofrequency ablation system designed to deliver targeted radiofrequency energy, effectively ablating spinal tumors while preserving surrounding healthy tissue (per invamed.com content surfaced via search index; the product page body is client-rendered and returned no additional detail on fetch).

How It Works and Where It Fits
INVAMED groups its ablation portfolio by the energy modality and anatomical target, offering radiofrequency platforms for soft tissue and bone as well as an intracavitary hypothermia set. Each device is intended for use by trained clinicians under appropriate image guidance and per the instructions for use (IFU). Microwave ablation generates an oscillating electromagnetic field at the antenna tip that agitates water molecules, producing frictional heat that can create a cytotoxic ablation zone in seconds to minutes. Laser trans-urethral ablation uses focused laser energy delivered through endoscopic instruments to vaporize or coagulate tissue from within the urinary tract without an external incision.
Key Considerations
- Achieving an adequate ablation margin is widely emphasized in the literature for durable local tumor control, and may call for overlapping applications in larger lesions.
- Tumor size, number, and proximity to vessels and adjacent organs are central factors in deciding whether ablation is appropriate and which modality to use.
- All INVAMED ablation devices are intended for use by trained clinicians under appropriate image guidance and in accordance with the IFU.
Frequently Asked Questions
What determines the ablation zone size?
Published sources note that factors such as generator power, applicator design, application time, and local blood flow influence the ablation zone, and settings are selected by the treating physician.
What radiofrequency ablation systems does INVAMED offer?
INVAMED offers the Peta RFA System, positioned for soft-tissue, liver, and nerve applications, the multi-application ThermoEdge RFA Platform, and the Fusion Intraosseous RFA System for spinal tumors.
Does ablation replace surgery?
Not necessarily; ablation is a local, minimally invasive option that may be considered instead of or alongside surgery in appropriately selected patients, and the decision is made within a multidisciplinary team.

Clinical and Technical Context
Manufacturer descriptions of INVAMED platforms reflect intended design and applications rather than guaranteed individual outcomes. Percutaneous tumor ablation is a group of minimally invasive techniques in which energy is delivered through a needle-like applicator, placed through the skin under imaging guidance, to destroy a focal tumor in situ. Achieving an adequate ablation margin around the tumor is a recognized goal in the literature, and the treating clinician judges whether a single or overlapping-ablation approach is warranted. Image guidance, applicator trajectory, and the decision to treat percutaneously versus by another route remain clinical judgments made by the operator.
