Abstract
A low cost, single-use disposable system for the thermocoagulation of tissue. The preferred embodiment of the present invention comprises an exothermic device for the treatment of cervical tissue or the like to provide low cost but effective treatment of, for example, precancerous conditions such as HPV (Human Papilloma Virus). The system provides an extremely cost efficient, easily implemented, single use, hygienic, rugged device which can be used in diverse conditions, requiring no power to operate, little training, and no other equipment.
Claims8
The method of applying heat to a target area, comprising the steps of:
- a. providing a canister containing an exothermic chemical, said canister formed of a heat conductive material, said canister having an exterior with an application tip shaped to engage a cervix of a patient;
- b. providing an extension to facilitate placement of said application tip to provide heat to said cervix;
- c. utilizing a catalyst fluid to react with said exothermic chemical to heat said application tip;
- d. positioning said application tip to engage said cervix with said extension, heating said cervix.
The method of applying heat to a target area, comprising the steps of:
- a. providing a canister having an exothermic chemical situated therein, said canister comprising a heat conductive material, said canister having associated therewith an application tip formed to thermally engage a cellular tissue of a patient, said canister having situated therein a membrane to contain said exothermic chemical, and to provide a volume for receiving a catalyst fluid for activation of said exothermic material;
- b. providing an extension to facilitate placement of said application tip so as to provide heat to said cellular tissue;
- c. providing said pre-measured amount of catalyst fluid to said canister comprising the sub-steps of:
- ci. filling said volume provided in said canister with said catalyst fluid, and
- cii. allowing said catalyst fluid to permeate said membrane to react with said exothermic material.
- d. utilizing said catalyst fluid to react with said exothermic chemical to heat said application tip of said canister, providing a heated application tip;
- e. positioning said heated application tip to engage said cellular tissue with said extension, so as to heat said cellular tissue.
The method of applying heat to a target area, comprising the steps of:
- a. providing a canister having an exothermic chemical situated therein, said canister having associated therewith an application tip formed to thermally engage a cellular tissue of a patient, said canister having situated therein a fluid impermeable membrane to separate said exothermic chemical from a pre-measured amount of catalyst fluid for activation of said exothermic material;
- b. providing an extension having a tip, said extension engaging said canister;
- c. utilizing said extension to position said application tip to engage said cellular tissue at said target area;
- d. urging said tip of said extension into said canister so as to rupture said membrane in said canister and facilitate the flow of said catalyst fluid to said exothermic material;
- e. utilizing said catalyst fluid to exothermically react with said exothermic chemical to heat said application tip so as to heat said cellular tissue at said target area.
