ThermoBLOCK is INVAMED's thermal coagulation radiofrequency ablation probe designed for use in hemorrhoid and anal fistula procedures. This article provides a technical overview of the device's design features and general mechanism of action, intended for healthcare professionals evaluating radiofrequency-based options in proctology practice.
What Is the ThermoBLOCK System?
ThermoBLOCK is a bipolar radiofrequency ablation probe engineered to deliver targeted thermal energy for coagulation of hemorrhoidal and select fistula-related tissue. The system operates using 4 MHz radiofrequency energy generated at the probe tip, with the generator providing up to 30 W of adjustable power supported by a catheter-recognition feature. The probe is designed as a sterile, single-use, disposable device, individually packaged in laminated sterile packaging to support standard procedural workflows.
What Are the Probe's Design Features?
The ThermoBLOCK probe is built around the following general specifications, as described on INVAMED's product materials:
- Tip length: 10 cm overall probe tip, with a 2 cm active treatment tip
- Catheter gauge: 18 gauge (1.3 mm) probe diameter
- Power delivery: Bipolar RF energy at 4 MHz, up to 30 W adjustable output
- Handling: Designed with a catheter pen holder intended to support control during energy delivery
- Sterility: Single-use, disposable, individually sterile-packaged
These features are intended to support a controlled, repeatable approach to thermal coagulation in the anorectal region, consistent with the device's intended use by trained healthcare professionals.
How Does the Mechanism of Action Work?
ThermoBLOCK is designed to induce coagulative necrosis at the treatment site through targeted radiofrequency-generated heat. The intended clinical effect described in general terms is protein denaturation and cellular desiccation within the targeted hemorrhoidal or fistula-related tissue, which is intended to promote fibrosis and volume reduction as part of the healing process. This mechanism places ThermoBLOCK within the broader category of thermal coagulation approaches discussed alongside laser-based hemorrhoidoplasty techniques, though the two use different energy modalities.
What Is the Device's Intended Clinical Context?
ThermoBLOCK is intended for use in hemorrhoid and select anal fistula procedures by trained healthcare professionals in appropriate clinical settings. As with other minimally invasive coagulation-based approaches, patient selection typically incorporates hemorrhoid grade, fistula characteristics, and overall clinical presentation. All procedures carry inherent risks and limitations, and the device should be used strictly according to its official Instructions for Use (IFU).
Frequently Asked Questions
What patient population is ThermoBLOCK generally discussed for?
ThermoBLOCK is generally discussed in the context of hemorrhoidal disease and select anal fistula presentations where a bipolar thermal coagulation approach may be considered appropriate by the treating physician, based on individual evaluation.
Is ThermoBLOCK reusable across multiple patients?
No. The ThermoBLOCK probe is designed as a single-use, disposable device, individually sterile-packaged, and is not intended for reprocessing or reuse between patients.
How does ThermoBLOCK's mechanism differ from laser-based hemorrhoid treatment?
Both approaches aim to induce controlled coagulation of hemorrhoidal tissue, but they use different energy sources — ThermoBLOCK delivers bipolar radiofrequency energy, while laser hemorrhoidoplasty uses laser fiber-delivered thermal energy. Clinical selection between modalities is determined by the treating physician based on the specific case.
