Intended Use
Increase of Local Blood Circulation. Treatment of Range of Motion when combined with exercise. Treatment for minor pain and stiffness of non-rheumatoid arthritis.
Device Story
Thermo-Therapy (Models TT-101, TT-201, TT-202) is a dry heat therapy device for professional physical and occupational therapy use. The device utilizes a fluidizing bed technology where ground cellulose is suspended in a heated air stream. The patient immerses an extremity (hand, wrist, foot, ankle, or lower leg) into the heated, fluidized cellulose. The medium provides gentle, warm massage to the extremity. The device is operated by clinicians to improve blood circulation, facilitate wound healing, and provide comfort. It is intended to assist in range of motion therapy and manage minor pain and stiffness.
Clinical Evidence
No clinical data provided; substantial equivalence is based on identical technological characteristics to the predicate devices.
Technological Characteristics
Dry heat therapy device using a fluidizing bed of ground cellulose. Operates via heated air stream to suspend cellulose particles. Dimensions vary by model (TT-101, TT-201, TT-202). Professional use only. No software or electronic algorithm described.
Indications for Use
Indicated for patients requiring increased local blood circulation, range of motion improvement (with exercise), or treatment for minor pain and stiffness associated with non-rheumatoid arthritis.
Regulatory Classification
Identification
An immersion hydrobath is a device intended for medical purposes that consists of water agitators and that may include a tub to be filled with water. The water temperature may be measured by a gauge. It is used in hydrotherapy to relieve pain and itching and as an aid in the healing process of inflamed and traumatized tissue, and it serves as a setting for removal of contaminated tissue.

Thermo-Electric Company is an Ohio Corporation having been in business since 1924 and is also The manufacture of many other products for the use in the professional physical and occupational therapy market.
The substantially equivalent (SE) product to our Thermo-Therapy is 510 (K) K871802 and 510 (K) K896817 both product code LSB and commonly known as Fluidotherapy.
The Fluidotherapy type devices describe a process where ground cellulose is held in animated The railoonetapy type do roos attrough a screen filter (often called the Fluidizing Bed) and held captive by a housing and flexible velcro tightening sleeves.
This process then allows for a hand, wrist, foot, ankle, and on larger units, the lower leg to be immersed in the heated cellulose.
The now fluidized cellulose gently and warmly massages the extremity resulting in improved blood circulation, wound healing, comfort, etc.
Thermo-Electric's Thermo-Therapy devices have identical technology characteristics to that of Fluidotherapy.
