Pyrexar Medical Innovative Cancer Solutions

We are the global leader in superficial and deep regional hyperthermia systems, developed as an adjunct solution, for the treatment of solid cancer tumors. Pyrexar RF uses non-ionizing radiation to excite surrounding cellular tissue to "fever" temperatures to increase effectiveness when used with radiotherapy.

    MA-151: mini-dual ridge wave guide applicators have an aperture of 4 x 5 cm and individual heating patterns approximately 2.5 x 2.5 cm by 2 cm deep. Advanced annular phased array principles create a central focusing of energy, which significantly overcomes the penetration losses of the energy radiated into the body.
  • MA-100 Wave Guide Applicator

    MA-100: side loaded wave guide applicators have a 10 x 13 cm aperture and a heating pattern approximately 8 x 10 cm by 2.5 cm deep.
  • Wave Guide Applicator

    MA-120: side-loaded wave guide applicator has an 18 x 24 cm aperture and a heating pattern of approxi- mately 12.5 x 19.5 cm by 2.5 cm deep.
  • Probe Calibration

    The Thermal Calibration Well can be used to quickly verify probe accuracy prior to treatment
  • Brachytherapy Treatment Support

    Interstitial hyperthermia delivers heat directly to the site of the tumor via brachytherapy catheter. The microwave power delivered to the antennas (available as an optional kit) can be adjusted in amplitude and phase to conform the heating pattern to the tumor.
  • The BSD-500 offers two USB ports for the offloading of patient records and keyboard/mouse. The system includes a wireless color printer. (model subject to change)
  • Water Circulation System

    Provides constant volume water supply to the Applicator Bolus with temperature range of 5 ̊C to 45 ̊C.
  • 915 MHz Eight-Channel Power Amplifier

    915 MHz Eight-Channel Power Amplifier Multi-channel solid state amplifier producing an available 480 Watts of RF power, (60 watts per channel) independently adjustable phase and amplitude.
  • Interchangeable Superficial Applicators

    Applicators available in multiple configurations to treat a range of tumor sizes and locations. Base model includes the MA-100 wave guide as shown.
  • MA-251 Microwave Interstitial Antenna

    The semi-rigid MA-251 microwave interstitial applicators can be inserted into 15.5 gauge (5 French) radiation implant catheters. The heat- ing pattern is ellipsoidal and approximately 4.5 cm in length along the applicator shaft with heating to the applicator tip.
  • BSD-500 Features

    • Portable
    • No shielding room needed
    • FDA Approved for palliative
      treatment of certain tumors
    • Delivers both superficial and
      interstitial hyperthermia

Who is Pyrexar Medical

Pyrexar Medical was formed to take on the fight against cancer. We purchased the Hyperthermia product line from BSD Medical in April 2015. Our plan is to support the existing BSD-500 and BSD-2000 customers, continue to make product improvements, support the growth of Thermal Oncology and spread the word about this amazing cancer therapy.

  • Color Printer

    The BSD-2000 computer system includes a wireless printer, keyboard/mouse, and USB ports for the offloading of patient records. (model subject to change)
  • Sigma 60 Applicator

    The Sigma 60 is an annular phased array applicator with 8 radiating dipoles, and a bolus membrane. The largest in the series with a 60cm opening. Advanced annular phased array principles create a central focusing of energy, which significantly overcomes the penetration losses of the energy radiated into the body.
  • Sigma 30

    The Sigma 30 is an annular phased array applicator designed for limbs. This applicator has also been used for Pediatric cancer treatment
  • Sigma Ellipse

    The Sigma Ellipse is an annular phased array applicator with 8 radiating dipoles, and a bolus membrane. The Sigma Ellipse provides improved comfort for smaller size patients. Applicator can be swapped out for different sizes.
  • Water Circulation System

    Provides constant volume water supply to the Applicator Bolus with temperature range of 5 ̊C to 45 ̊C.
  • Patient Support System

    Hydraulic patient sling allows for the centering of the patient in the applicator.
  • Control Panel

    Easy to use controls for patient positioning and bolus water fill/circulation

Benefits of Hyperthermia in Cancer Treatment

Shrinks Tumors

In the delicate micro-environment of a cancer cell, heat can lead to direct cell death, shrinking tumors size for easier surgical resection.

Low Toxicity

Very low to no toxicity is often reported when administering hyperthermia. There is no known toxicity build-up from multiple treatments.

Increase Blood Flow

Increased blood flow and perfusion at the tumor site promotes oxygenation, increasing radiosensitivity.

Survival Benefit

A phase III clinical study shows an increased survival benefit when hyperthermia was added to traditional therapies.

Inhibits DNA Repair

Hyperthermia in combination with Radiotherapy will inhibit the DNA repair cycle of radiation damaged cancer cells.

Heat Shock Proteins

Tumor cells express heat shock proteins when exposed to hyperthermic temperatures allowing tumor specific antigens to reach the immune system.
