Abstract: The present disclosure relates to a dialysis device (1), more particularly a microdialysis device for the sampling of substances from the surface of a body organ. The device is particularly useful in the context of the monitoring of a moving organ, such as a beating heart, as the device comprises attachment means (2) allowing for a flexible and reliable attachment thereto. Furthermore, the microdialysis device provides for an efficient exchange of substances, such as metabolic substances, between the organ and the dialysis fluid through a semi-permeable material forming part of the device. There is also provided a method encompassing the device of the disclosure.

Abstract: A micro-calorimeter apparatus includes a thermostated housing (3,4,5); a pair of essentially flat heat sinks (9,10), suspended in the housing (2) and thermally floating relative to the environment inside the housing (3,4,5). The heat sinks (9,10) are arranged with their surfaces facing each other. A pair of Peltier elements (11) are thermally attached to the heat sinks (9,10), one element (11) on each heat sink (9,10), on the facing surfaces, forming a gap between them for the accommodation of a generally flat biosensor unit (12).

Abstract: In general terms the biosensor apparatus according to the invention comprises a housing (5, 6), a pair of heat sinks (11, 12) and a pair of heat reflectors (13, 14) thermally floating relative to the heat sinks, and a pair of Peltier elements (16) attached to and in thermal contact with the heat sinks (11, 12), one element (16) on each heat sink (11, 12). The housing is made of an insulating material, and the heat sinks (11, 12) are made of a material with thermal properties large enough to absorb the heat flow with only a very slight, negligible disturbance in its temperature, to render their envelope surface having a high heat emissivity. The heat reflectors (13, 14) are made of a material having a very low emissivity and have a generally flat and thin disc shaped structure and acts primarily as radiation shields.
