An apparatus for determining a thermal property of tissue includes a base unit with one or more energy source and at least two, preferably detachable, leads. The distal end of each lead, which is introduced into the tissue to be treated, has at least two longitudinally spaced temperature measuring elements to measure surrounding tissue temperature and at least two longitudinally spaced electrode surfaces for applying current to the tissue. Each distal end is also provided with an element which uses energy emitted by the sources of energy to heat up the surrounding tissue. The base unit has computing elements, current generating elements for generating an alternating current, and conductance determining elements for determining the tissue conductance between pairs of electrode surfaces based on the alternating current applied by the current generating elements to the tissue. Methods for using the device and leads for use in the device are also described.

Apparatus and methods for determining a property of a tissue

An arrangement for the exposure of a pumpable medium to an electric field. The arrangement comprises, at least two power supplies () for the generation of electrical voltage, at least one non-conducting chamber () for pumping said pumpable medium, which said at least one chamber () is provided with a first () and a second electrode plate (), a control means () for controlling said at least two power supplies (). During control the control means (), by synchronous control, establishes a series connection between at least two of said at least two power supplies (), the first electrode plate () and the second electrode plate (). A resulting composite voltage arises between the first () and the second electrode plate (), which resulting composite voltage will result in an electric field between the first () and the second electrode plate (). The pumpable medium is exposed to the electric field. A method for the exposure of a pumpable medium to an electric field is also provided.
