Abstract
A tissue treatment apparatus is provided which includes a thermally conductive bandage, a heater in thermal contact with the bandage over a tissue treatment area, a heat spreading means acting between the heater and the bandage for laterally spreading heat transferred from the heater to the bandage in order that heat be substantially uniformly distributed across the bandage.
Claims15
A tissue treatment apparatus comprising:
- a flexible, planar bandage with a surface for being depressed into tissue;
- adhesive on the surface of the bandage;
- a flexible, planar heater;
- and,
- a heat-spreading layer of thermally conductive material sandwiched between the heater and the bandage;
- the heat-spreading layer being a pouch and a thermally conductive fluid in the pouch.

A tissue treatment apparatus comprising:
- a flexible, planar bandage with a surface for being depressed into tissue;
- a pattern of adhesive on the surface;
- the pattern of adhesive having a pull strength;
- a flexible, planar heater;
- a heat-spreading layer of thermally conductive material sandwiched between the heater and the bandage;
- and
- double-sided tape attaching the heater to the heat-spreading layer;
- the double-sided tape having a pull strength less than the pull strength of the pattern of adhesive.
