Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
117 words
A method of providing thermal therapy to prostate tissue of a patient, comprising the steps of: inserting a fluid infusing device into the patient; locating the fluid infusing device at a location adjacent a portion of the patient's prostate and the patient's rectum to provide passage of a volume of a fluid from the device to said location without a containment structure between the portion of the patient's prostate and the rectum, said location selected to allow said fluid to begin physically separating the portion of the prostate and the rectum; continuing to infuse said fluid causing physical separation of the portion of the prostate and the rectum; and applying said thermal therapy to the prostate tissue.
Claim 2
Independent Claim
117 words
A method of providing thermal therapy to prostate tissue of a patient, comprising the steps of: inserting a fluid infusing device into the patient; locating the fluid infusing device at a location adjacent a portion of the patient's prostate and the patient's rectum to provide passage of a volume of a fluid from the device to said location without a containment structure between the portion of the patient's prostate and the rectum, said location selected to allow said fluid to begin physically separating the portion of the prostate and the rectum; continuing to infuse said fluid causing physical separation of the portion of the prostate and the rectum; and applying said thermal therapy to the prostate tissue.
Claim 3
Dependent Claim
32 words
The method as defined in claim 1, further including the step of continuing to infuse said fluid to completely physically separate all portions of the prostate and the rectum with said fluid.
Claim 4
Dependent Claim
20 words
The method as defined in claim 1, wherein said location is disposed in a biplane fascial layer of the patient.
Claim 5
Dependent Claim
16 words
The method as defined in claim 1, including the step of delivering the fluid under pressure.
Claim 6
Dependent Claim
19 words
The method as defined in claim 1, including the step of using a recirculating apparatus to recirculate said fluid.
Claim 7
Dependent Claim
24 words
The method as defined in claim 1, and including the step of positioning the temperature sensor to be disposed in contact with said fluid.
Claim 8
Dependent Claim
13 words
The method as defined in claim 1, wherein said fluid cools the rectum.
Claim 9
Dependent Claim
13 words
The method as defined in claim 1, wherein said fluid is a liquid.
Claim 10
Independent Claim
75 words
A method of providing thermal therapy to prostate tissue of a patient, comprising the steps of: providing a gel to a location adjacent a portion of the patient's prostate and the patient's rectum, said location selected to allow said gel to begin physically separating the portion of the prostate and the rectum; said gel causing physical separation of the portion of the prostate and the rectum and applying said thermal therapy to the prostate tissue.
Claim 11
Independent Claim
75 words
A method of providing thermal therapy to prostate tissue of a patient, comprising the steps of: providing a gel to a location adjacent a portion of the patient's prostate and the patient's rectum, said location selected to allow said gel to begin physically separating the portion of the prostate and the rectum; said gel causing physical separation of the portion of the prostate and the rectum and applying said thermal therapy to the prostate tissue.
Claim 12
Independent Claim
139 words
A method of providing thermal therapy to prostate tissue of a patient, comprising the steps of: inserting a fluid infusing device into the patient; locating the fluid infusing device at a location adjacent a portion of the patient's prostate and the patient's rectum to provide passage of a volume of a fluid from the device to said location without a containment structure between the portion of the patient's prostate and the rectum, said location selected to allow said fluid to begin physically separating the portion of the prostate and the rectum; continuing to infuse said fluid causing physical separation of the portion of the prostate and the rectum; applying said thermal therapy to the prostate tissue; and using a temperature sensor to sense temperature of the volume of fluid to minimize damage to the prostate and to the rectum.
Claim 13
Independent Claim
139 words
A method of providing thermal therapy to prostate tissue of a patient, comprising the steps of: inserting a fluid infusing device into the patient; locating the fluid infusing device at a location adjacent a portion of the patient's prostate and the patient's rectum to provide passage of a volume of a fluid from the device to said location without a containment structure between the portion of the patient's prostate and the rectum, said location selected to allow said fluid to begin physically separating the portion of the prostate and the rectum; continuing to infuse said fluid causing physical separation of the portion of the prostate and the rectum; applying said thermal therapy to the prostate tissue; and using a temperature sensor to sense temperature of the volume of fluid to minimize damage to the prostate and to the rectum.
