DIATHERMY Diathermy is when high frequency currents are used to heat, cut, coagulate, anddestroy tissues. Diathermy Machines were used to lower blood pressureelectrically before medications were available. When used surgically, theywere most beneficial in the removal of cancerous cysts. Unlike thescalpel, where excessive bleeding occurred (and re-infecting good tissueswith bad cancer cells) electrical cutting of tissues allowed the blood vesselsto be sealed as they were cut...cysts could be cooked in a sense before removed,and all in all the procedures had an overall success rate that was higher andwith a speedier recovery. Today they are replaced with lasers, andalthough they look straight out of Frankenstein were actually legitimate medicaltools in the 1920s, even if occasionally they were pawned off by quacks ;) ... Oudin Resonators were large Tesla Coils used to apply sparks to the skin anddiffuse electricity to produce physiological effects on the body.
H. G. Fischer G2 Spark Gap Diathermy Machine, 1930s
Slicing instantaneously through 25mm of steak using a diathermy machine. Themeat was sliced 18mm deep using a a 1/2mm needle moving as fast as my hand couldtravel.

An inexpensive 1940s Diathermy Machine made by Physician's Equipment Co.
After short wave Diathermy they experimented with ultrasonic diathermy.
Unpulsed as this machine generates and later they switched to pulse diathermy toavoid breaking down bone structure.

Most manuals recommended practicing on steak before moving to patients...
Diathermy was commonly used for electro surgery in cases where excessivebleeding could occur with a scalpel.
It was often used to remove the tonsils.
Diathermy was also used to induce heat in tissues for rehabilitation.
It was used to treat skin cancer as well as for removing malignant growthssurgically.
Diathermy was also used to treat the cervix and prostate.

Originally designed for brain surgery.
A larger version of the same machine. This machine became a long standingsurgical unit well into modern times.

A series of pristine Diathermy Machines from David Genser (RIP) AKA Darkerwaters.
Dave was a great guy who did special effects for X-files and provided highvoltage props for Alice Cooper concerts.
He also blamed me for spending over $35K in machines after gettinginspired from my website.
He restored machines to better-than-new condition, a painstaking process!

By passing electricity through her body to a metal wand she was able to igniteexplosive gases that were introduced into the jack-o-lanterns.
Dr. FrederickFinch Strong and his wife Ethel. Pioneers in this field.
The concept of the Oudin Resonator modified by Jeff Behary and engineeredto make artificial lightning.
Note the lamps lighting without wires in the photo above.
