  • Patent number: 6314315
    Abstract: The invention provides methods and kits relating to identification of ductal orifices on a mammalian breast nipple. The methods employ technology to measure characteristic electrical signals on a nipple surface to locate and image or map the ductal orifices on the nipple surface. Kits are also provided comprising materials for identifying a duct by characteristic electrical signal, and for additionally analyzing the signals, and accessing or marking the ducts once they have been identified by the characteristic electrical signal values.

  • Patent number: 6197327
    Abstract: Methods, devices, and compositions for treatment of dysmenorrhea comprise an intravaginal drug delivery system containing an appropriate pharmaceutical agent incorporated into a pharmaceutically acceptable carrier whereby the pharmaceutical agent is released into the vagina and absorbed through the vaginal mucosa to provide relief of dysmenorrhea. The drug delivery system can be a tampon device, vaginal ring, pessary, tablet, suppository, vaginal sponge, bioadhesive tablet, bioadhesive microparticle, cream, lotion, foam, ointment, paste, solution or gel. The system delivers a higher concentration to the muscle of the uterus, the primary site for the dyskinetic muscle contraction, which is the pathophysiologic cause of dysmenorrhea.

  • Patent number: 6063051
    Abstract: A computer based system for tracking a patient's fluid volume and electrolyte (cation or anion concentration) balances, during the period extending from before surgical procedures through the recovery process, which will assist the attending physician in maintaining proper balances in the patient. The system contains automatic sensors for measuring the volumes of fluids administered to and recovered from the patient. The system also preferably contains sensors for measuring electrolyte concentrations in these fluids, and, when sensors are not available, assists the attending physician in estimating. The system assists the attending physician in creating baseline values for a patient's fluid and electrolyte values, and then accounts for the fluids going into and out of the patient to continuously track current values. Out of bounds conditions for these balances, when detected, will cause the system to issue alarms and make suggestions to the attending physician for remedial action.

  • Patent number: 6041260
    Abstract: An endometrial ablation apparatus and method wherein an RF current having a frequency of between 250 kHz and 100 MHz is passed through the entire surface of an endometrium in order to provide heating of the endometrium. An electroconductive expandable member such as a balloon is used as the medium for passing the current and causing the heating of the endometrium. The temperature of the endometrium is raised to a temperature between 45.degree. C. and 90.degree. C. and preferably not above 70 for a time sufficient to destroy the cells of the lining while maintaining the average temperature of the myometrium at a temperature below approximately 42.degree. C. The expandable balloon is connected to a power source which provides the radio frequency power having the desired characteristics to selectively heat the endometrial lining to the desired temperature.

  • Patent number: 5897552
    Abstract: An ablation electrode carries a temperature sensing element for measuring the temperature of the tissue being ablated. A thermal insulating element associated with the sensing element blocks the transfer of heat energy from between the temperature sensing element and the body. The temperature sensing element therefore measures temperature without being affected by the surrounding thermal mass of the electrode.
