The CTC-7 Device

The CTC-7 Device is an iceless and portable all in one rehabilitation system for athletes recovering from sports injuries and for patients’ post-operative recovery. The CTC-7 offers cryotherapy, thermotherapy and contrast therapy treatments. With the option of intermittent pneumatic compression therapy alongside these temperature settings. These treatments can help to reduce the recovery time period of a patient or athlete.

G&N are now offering direct rental services for the CTC-7 device for patients and athletes for just £290 a month. Submit your interest here.

The CTC-7 device allows you to customise the temperature, compression level and cycle time for optimum treatment. There are a variety of wraps available with the CTC-7: Elbow Wrap, Knee Wrap, Ankle Wrap, Shoulder Wrap, Back Wrap & Universal Wrap, to cover all treatment areas.

The iceless nature of the CTC-7 device means that only 200ml of distilled water is needed to perform multiple treatment cycles and that there is a continuous temperature applied to the patients’ therapy area. Providing more convenience without having to regularly top up with ice and more effective treatment without temperature fluctuation as the ice melts.
