Patent number: 6085115Abstract: A method for measuring biopotential of an organism includes electroporating a portion of a tissue surface of the organism. The biopotential of the organism is then measured with electrodes at the electroporated portion of the organism. The portion of the organism that is electroporated can be, for example, a skin surface of the organism. A resistance-decreasing agent, such as heparin, sodium thiosulfate, thioglycolic acid solution and dithioglycolic acid can be applied to the tissue surface to facilitate reduction in electrical resistance. Another example of a resistance-decreasing agent is a keratin-disrupting agent, such as sulforhodamine. Examples of suitable biopotential measurements include electrocardiographic, electroencephalographic, electromyographic, electrohysterographic and elctrokymographic measurements. The method decreases skin resistance to diminish unwanted electrical voltages that compete with biopotential measurements, thereby significantly improving the biopotential measurement.Type: GrantFiled: May 22, 1998Date of Patent: July 4, 2000Assignee: Massachusetts Institite of TechnologyInventors: James C.

Patent number: 5911223Abstract: A method of modifying epidermis for transport of a material by electroporation includes applying to epidermis an agent that, upon entry into the epidermis, will modify the epidermis to thereby cause and altered rate of transport of a material across the epidermis. Typically, the altered rate will be an increased rate of transport. The epidermis is electroporated, whereby at least a portion of the modifying agent enters the electroporated epidermis, thereby modifying the epidermis to cause an altered rate of transport of a material across the epidermis. In another embodiment, the modifying agent can modify the epidermis to enable measurement and/or monitoring of physiological conditions or change within or beneath the epidermis. The modifying agents can also be employed to facilitate discharge of fluids from within an organism, such as by providing pathways for discharge of fluids from a tumor.Type: GrantFiled: August 9, 1996Date of Patent: June 15, 1999Assignees: Massachusetts Institute of Technology, The Regents of the University of CaliforniaInventors: James C.
