Pain Management RF Generator Companies & Models

Pain Management RF generators and companies have gone through some significant changes since year 2000 when Radionics, Inc. was sold with 98% market share.  Therefore, this article will focus on pain management RF generators manufactured after year 2000 with the introduction of Stryker, Baylis Medical-Kimberly/Clark, and Neurotherm.  We encourage facilities considering new RF generators to bring in all the companies through their limited free trial programs. The trial programs are an ideal way to accommodate initial patients, gain clinical & administrative experience, while simultaneously learning the details about the company’s RF products and support.

How much does a RF Generator Cost?

New Pain Management RF Generators range in price from $15,000.00-$45,000.00 depending on the system, the electrode configuration, the competition involved, and the anticipated consumable volume at a center.  The most advanced RF generators are dedicated multi-lesion systems that perform 4 lesions simultaneously with independent controls of the electrodes. The Boston Scientific/Cosman G4, Abbott Medical/Neurotherm NT2000IX, and the Stryker  MultiGen RF generators are dedicated 4 lesion RF generators. The Avanos/Halyard Baylis PMG RF generator is the original single lesions system but the MLM to disperse the energy to the electrodes. This design is categorized as multi-lesion, but on the lower end technology solution with inherent limitations due to the lack of control of the energy.   

Abbott Medical/St. Jude Medical/Neurotherm RF Generator

Neurotherm RF generators were originally imported from the UK by former Radionics, Inc. employees. Neurotherm was the first company to introduce a multi-lesion 3 electrode RF generator in 2007, which accelerated their market integration.  This quick growth lead to the initial management selling Neurotherm in year 2008 to a Venture Capital firm. In 2014, the capital firm sold Neurotherm to St. Jude Medical for $200 million. In 2016, St. Jude Medical was purchased by Abbott Medical for $25 billion. Neurotherm has had 4 owners since year 2002 with financial growth initiatives and inferior GMP which resulted in a 2012 FDA action.

The Neurotherm products have had an extensive history with adverse clinical events that Abbott Medical is working to improve.

Neurotherm NT 1000: The first multi-lesion 3 lead RF generator.

The NT 1000 Series 3 lesion RF generator success and sales growth gained significant market share for Neurotherm   The Neurotherm NT1000 & 1100 are lower powered 30 watt systems have a large angled screen that is not active during the operation. The unit must be operated with a set of 14 buttons on the front panel, which requires some training.

Neurotherm NT1100:

Neurotherm did not upgrade the power on the 1100 leaving it underpowered at 30 watts, which is the lowest available.  Users should be aware that a larger RF cannula may take up to 60 seconds to get to temperature if a impedance issue is experienced.  And many users find the system difficult to operate with a slow ramp up time that can take as long as two minutes, slow screen transitions, and hidden button functions codes that require training.

Neurotherm NT 2000IX RF Generator

The Neurotherm NT2000 display is angled and does not fully operate the system. Operators must use the output control knobs during the procedure. Upgrading the power to 50 Watts helped their ramping and power issues but the NT2000 lacks some basic functions and readouts that other systems have in all modes. The NT2000 does not read impedance when in stimulation mode, you cannot change setting during the procedure which requires ending the procedure to change a setting.

Avanos Pain Management/Halyard/Baylis RF Generator:

Baylis Medical out of Canada was the the original founders of the RF generator provided by this company. Baylis Medical was purchased by Kimberly-Clark in the mid 2000’s and operated under the Kimberly-Clark name until a name transfer to Halyard Health in 2016, In 2018 another name transferred occurred and they are operating as Avanos Pain Management as of 2018.  4 names in 15 years seems confusing to the long established and new to market end-users. We hope this helps a little. Software Version 3 was released in 2007 with software level determining system capability.

One should note that Avanos is continuing to market the original single lesion PMG RF generator from the early 2000’s, They are the only company that has not released a new generator since its introduction in year 2000.  The Baylis (MLM) Multi Lesion Module enables the splitting of the systems power to each electrode, which is not a dedicated multi lesion system.  Avanos continues to pursue a technology called Cool RF that was invented by Dr. Eric Cosman Sr, PhD.(MIT), coordinating physicians, and engineers at Radionics, Inc. See Cosman’s family history with MIT programs and the innovations that were developed at Radionics, Inc.

Boston Scientific /Cosman G4 RF Generator:

In 2016 Boston Scientific purchased Cosman Medical, Inc. from the Cosman family in July 2016.  The Cosman family are the founders and innovators of RF Medicine for over 60 years out of MIT Physics department.   The Cosman’s history and contributions are significant in the field of RF Medicine The Cosman G4 is the most advanced system, the easiest to use, and the most reliable technology available.

The G4’s quality is evident by their scarcity on the secondary market. The G4 consists of a 12” color-coded screen that only displays active electrodes creating large readouts. With a test plug operators can always test the system prior to clinical operation. With the only wireless hand control available, 3 USB ports, and the reputation of Cosman customers are always please with their systems.

Cosman RFG-1B Single Lesion RF Generator

Cosman RFG-1B is an advanced system but with analog look and operation.  This system will likely be with a user their entire career if they choose.  No color coded screens, no software with drivers, no touch screen.  The readouts are clear, the function is practical, and the generator is robust.

Stryker RF Generators:

Stryker Pain Management RF generators released their automated single lesion automated RF generator in the early 2000s.. Initially the Stryker RF systems were manufactured by Valley Forge, Scientific Inc. in PA with manufacturing transferring to St. Louis, Missouri by Synergetics. Inc.  Synergetics, was purchased by Stryker in 2016.

Stryker MultiGen RF Generator:

Stryker released the MultiGen in year 2006 and it has been proven to be a reliable but costly system to operate. The MultiGen has a corded wired hand control, a manual stagger start, and a 9.5” screen that continuously shows 4 electrodes-even when using less. The small monochromatic numeric create a display that is difficult to read and navigate. The MultiGen Rev 1 are starting to appear on the secondary market in the $10,000.00 range. It is a more difficult system to operate in comparison to a Boston Scientific Cosman G4 or MultiGen 2.

Stryker MultiGen 2 RF generator

In 2017 Stryker released the Stryker MultiGen 2 with a 100 watts of power to reduce ramp up times on larger cannula and Venom electrodes. Other features include electrode usage tracking, USB data exportation, and a smart splitter electrode module with full touch screen controls.  The MultiGen 2 has a reduced screen size from 9.5″ to 8”.  The electrode module is a drop consideration and should be handled and secured accordingly.
