Abstract
Abstract Conditions, such as tumors, in a living body are treated by applying localized infrared electromagnetic energy to the affected area of the body. The energy is selected to have a wavelength such that the energy is absorbed by the cells, and the amplitude of the energy is adjusted to a value that is effective to cause destruction of defective cells without destroying healthy cells. Preferably, the energy is derived from a flowing fluid having a temperature within the normal operating temperature range of the body, which determines the wavelength of the energy, and the amplitude of the energy is adjusted by controlling the flow rate of the fluid.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
107 words
A method of treating a condition in a living body that is produced by defective cells comprising applying to an area of the body containing the defective cells localized infrared electromagnetic energy having a wavelength such that the energy is absorbed by the defective cells, the energy being derived from a flowing fluid having a temperature within the normal operating temperature range of the body and the wavelength of the energy being determined by said temperature, and adjusting the amplitude of the energy, by adjusting the flow rate of the fluid, to a value that is effective to substantially destroy defective cells without substantially destroying healthy cells.
Claim 2
Independent Claim
107 words
A method of treating a condition in a living body that is produced by defective cells comprising applying to an area of the body containing the defective cells localized infrared electromagnetic energy having a wavelength such that the energy is absorbed by the defective cells, the energy being derived from a flowing fluid having a temperature within the normal operating temperature range of the body and the wavelength of the energy being determined by said temperature, and adjusting the amplitude of the energy, by adjusting the flow rate of the fluid, to a value that is effective to substantially destroy defective cells without substantially destroying healthy cells.
Claim 3
Dependent Claim
19 words
The method of claim 1, wherein the energy is selected to have a wavelength at which the cells resonate.
Claim 4
Dependent Claim
16 words
The method of claim 2, wherein the wavelength is in the 9 to 10 micron range.
Claim 5
Dependent Claim
22 words
The method of claim 1 wherein the temperature of the fluid is in the range of about 96° F. to 102° F.
Claim 6
Dependent Claim
11 words
The method of claim 1, wherein said condition is a tumor.
Claim 7
Dependent Claim
37 words
The method of claim 5, wherein said flowing fluid comprises a gas that is injected into the body adjacent to the tumor and removed from the body such that a gas flow is produced across the tumor.
Claim 8
Dependent Claim
31 words
The method of claim 6, wherein the gas that is injected into the body is supplied from a source of pressurized gas that is heated to provide a predetermined gas temperature.
Claim 9
Dependent Claim
30 words
The method of claim 7, wherein the gas is injected into and removed from the body by first and second tubes, respectively, implanted within the body adjacent to the tumor.
Claim 10
Dependent Claim
29 words
The method of claim 8 further comprising removing gas that flows across the tumor from the body at the same rate as the gas is injected into the body.
Claim 11
Dependent Claim
16 words
The method of claim 9, wherein said removing comprises applying a vacuum to the second tube.
Claim 12
Dependent Claim
36 words
The method of claim 10 further comprising controlling the temperature and flow rate of the gas to provide a temperature of the order of 102° F. and a flow rate of the order of 2.4 CFM.
Claim 13
Dependent Claim
26 words
The method of claim 5, wherein the flowing fluid comprises a liquid flowing through a tube implanted within the body at the region of the tumor.
Claim 14
Dependent Claim
18 words
The method of claim 12, wherein the tube is implanted within the body in contact with the tumor.
Claim 15
Dependent Claim
38 words
The method of claim 12 further comprising controlling the temperature and flow rate of the liquid to provide a temperature of the order of 102° F. and a flow rate of the order of 15 ounces per second.
Claim 16
Dependent Claim
26 words
The method of claim 5 further comprising applying energy to the tumor for a period of time that is proportional to the size of the tumor.
Claim 17
Independent Claim
76 words
A method of treating a tumor in a living body comprising implanting a tube within the body adjacent to the tumor, passing a flowing fluid into the body through the tube, the fluid having a temperature within the normal operating temperature range of the body, removing the flowing fluid from the body, and adjusting the flow rate of the fluid to a value that is effective to substantially destroy tumor cells without substantially destroying healthy cells.
Claim 18
Independent Claim
76 words
A method of treating a tumor in a living body comprising implanting a tube within the body adjacent to the tumor, passing a flowing fluid into the body through the tube, the fluid having a temperature within the normal operating temperature range of the body, removing the flowing fluid from the body, and adjusting the flow rate of the fluid to a value that is effective to substantially destroy tumor cells without substantially destroying healthy cells.
Claim 19
Dependent Claim
46 words
The method of claim 16, wherein the fluid comprises a gas injected into the body adjacent to the tumor such that a gas flow across the tumor is produced, and wherein the gas flowing across the tumor is removed by another tube implanted within the body.
Claim 20
Dependent Claim
22 words
The method of claim 16, wherein the fluid comprises a liquid that flows into and out of the body via the tube.
Claim 21
Dependent Claim
28 words
The method of claim 16 further comprising subjecting the tumor to said flowing fluid for a period of time that is proportional to the size of the tumor.
Claim 22
Dependent Claim
22 words
The method of claim 16, wherein the temperature of the fluid is in the range of about 96° F. to 102° F.
