Handheld massage device

1. A massage device comprising:

a housing having a surface and an internal cavity;

a plurality of rounded upwardly projecting pressure point protrusions formed on at least a part of the surface of the housing;

an elongate linear recess having no protrusions over a surface of the elongate linear recess, the recess being formed in the part of the surface having the protrusions and having a width which enables it to receive the spine of a person;

a first and second lateral wall on first and second sides of the recess respectively, the lateral walls having a top edge and being spaced from each other by a distance sufficient to straddle the spine of the person, and wherein the protrusions are adapted to contact the back of the person on each side of the spine;

a plurality of rounded top edge protrusions arranged linearly on a part of the top edge of the lateral walls and undulations on a second part of the top edge of the later walls;

a fill material in the form of water contained within the internal cavity, the water being heatable to a selected temperature so that the water temperature and the pressure of the pressure point protrusions in combination provide an enhanced therapeutic effect.

2. A massage device as claimed in claim 1 configured in the form of an elongate roller, and wherein the pressure point protrusions are in the form of radially outwardly projecting ribs extending in circular rows outwardly from the elongate linear recess toward outer ends of the roller.

3. A massage device as claimed in claim 2 wherein one of the row of ribs project outwardly and differ in size and orientation from at least one other of the row of ribs.

4. A massage device as claimed in claim 2 wherein one of the row of ribs project outwardly and differ in size and orientation from at least one other of the row of ribs.

5. A method of massaging a user comprising:

providing a massage device having a surface which defines an internal cavity;

forming a plurality of rounded upwardly projecting pressure point protrusions on at least a part of the surface of the massage device;

providing an elongate linear recess with no protrusions over a surface of the elongate linear recess, the recess being formed in the part of the surface having the protrusions and having a width which enables it to receive the spine of a person;

locating a first and second lateral wall on first and second sides of the recess respectively, the lateral walls being spaced from each other to straddle the spine of the person, and wherein the protrusions contact the back of the person on each side of the spine;

forming a plurality of rounded top edge protrusion arranged linearly on a part of a top edge of the lateral walls and undulations on a second part of the top edge of the lateral walls

filling the internal cavity with a medium in the form of water; and

heating the massage device and the water contained in the internal cavity so that the temperature of the heated massage device in combination with the pressure point protrusions provide an enhanced therapeutic benefit, and applying the massage device to the user.

6. A method as claimed in claim 5 wherein the internal cavity is filled with approximately 375 g of water and heated in a 1000 W microwave for about two minutes for generating about 130 minutes of constant and substantial heating creating a temperature of about 101.3 degrees F. on the user's body surface.

7. A method as claimed in claim 5 wherein the internal cavity is filled with approximately 375 g of water and heated by boiling for about 15 minutes for generating about 130 minutes of constant and substantial heating creating a temperature of about 101.3 degrees F. on the user's body surface.

8. A method as claimed in claim 5 wherein the massage device is formed as a roller with the plurality of pressure point protrusions formed in circular rows about the roller.

9. A method as claimed in claim 8 wherein the internal cavity is filled with approximately 300 g of water and heated in a 1000 W microwave for about 90 seconds for generating about 105 minutes of constant and substantial heating creating a temperature of about 101.3 degrees F. on the user's body surface.

10. A method as claimed in claim 8 wherein the internal cavity is filled with approximately 300 g of water and heated by boiling for about 12 minutes for generating about 105 minutes of constant and substantial heating creating a temperature of about 101.3 degrees F. on the user's body surface.

11. A method as claimed in claim 5 wherein the combination of heat and pressure facilitates release of tight areas in spinal joints, connective tissues, and muscles without application of active force.

12. A method as claimed in claim 5 wherein the pressure point protrusions are formed as ribs extending outwardly from the surface of the massage device.

13. A method as claimed in claim 12 wherein the ribs are configured with different shapes and sizes over the surface of the massage device.
