ThermoBLOCK Thermal Coagulation Ablation Probe for Hemorrhoids & Anal Fistulas

A minimally invasive device designed to deliver precise thermal energy, effectively coagulating tissue to treat hemorrhoids and anal fistulas while minimizing discomfort and promoting rapid recovery.

ThermoBLOCK is an advanced radiofrequency-based solution engineered for fast, safe, and effective treatment of hemorrhoids (HD) and anal fistulas. Utilizing 4 MHz radiofrequency to generate targeted thermal energy at the probe’s tip, ThermoBLOCK induces coagulative necrosis—offering a minimally invasive technique that can significantly alleviate patient symptoms with reduced procedural discomfort and faster recovery times compared to conventional surgical approaches.

Key Features and Technology

4 MHz Radiofrequency Generator
  • High-Frequency Energy: Produces rapid radio waves that heat tissue at the probe tip, delivering precise thermal ablation.
  • Controlled Coagulation: Limits excessive spread of heat, preserving surrounding healthy tissue and minimizing collateral injury.
  • Intracellular Vaporization: The intense heat causes intracellular water to boil, raising cell pressure until it ruptures from within—known as cellular volatilization.
  • Coagulative Necrosis: Targeted tissue necrosis leads to fibrotic changes or plication of the anorectal mucosa in hemorrhoids, diminishing prolapse and related symptoms.
  • Slim, Maneuverable Probe: Facilitates straightforward positioning in the anal canal, ensuring minimal discomfort and easy angle adjustments.
  • Reduced Postoperative Pain: With no significant cutting or stitching, ThermoBLOCK can enable a quicker return to daily activities.
  • Short Ablation Times: High-frequency radio waves rapidly create the desired necrotic effect, reducing total procedure length.
  • Outpatient Potential: Many treatments can be performed under local or regional anesthesia, lowering hospital resource usage.

Clinical Advantages & Indications

Hemorrhoid Management
  • Targeted Hyperthermia: Elevates local temperature in the bladder to potentiate chemotherapeutic effects, thereby improving tumor cell kill rates.
  • Increased Drug Penetration: Heated environment encourages deeper and more consistent uptake of anticancer agents.
  • Combination of Heat & Ionized Molecule Delivery: Creates a synergy that overcomes drug resistance and fosters thorough coverage of bladder lesions.
  • Reduced Systemic Toxicity: Local administration confines drug exposure mainly to the bladder region, potentially lowering systemic side effects.
  • Outpatient/Local Anesthesia: Many procedures can be performed on a short-stay basis, optimizing hospital resources and improving patient quality of life.
  • Reliable Monitoring & Control: Comprehensive alarm systems plus real-time temperature feedback maintain high standards of safety.
  • Automatic Safety Shutdown: Mitigates risk if unexpected temperature or pressure fluctuations occur.
  • Alarm Alerts: Minimizes operator error and ensures the procedure remains within the safe therapeutic window.
