Abstract: The subject of the invention is a system for inducing an electric field in a conducting medium, especially for medical applications. The system induces flow of electric current through objects located in the conducting medium, and has a medical application consisting in a nerve impulse block. In one embodiment the system, which may be implantable, comprises a torus-shaped encasement having an electrically non-conductive outer surface and one or more cores, which are optionally locally joined together by a joining material, situated inside the encasement. One or more windings are configured to pass electric current to change magnetic flux, which is substantially confined within the one or more cores and the joining material, if present. In some embodiments the outer surface has geometric continuity of order 1 or higher.

Abstract: The subject of the invention is a system for inducing an electric field in a conducting medium, especially for medical applications. The system according to the invention induces a flow of electric current through objects located in the conducting medium, which may have shapes that are complex or change with time, and has a medical application consisting in a complete or partial nerve impulse block. The system for inducing an electric field in the conducting medium comprises at least two component cores, whose magnetization is configured to be changed independently by a change of electric currents flowing through windings that are wound around them, and a torus-shaped encasement whose outer surface is electrically non-conductive, wherein the component cores are situated inside the encasement and encircle its opening, and the encasement is situated inside the conducting medium.

Abstract: The subject of the invention is a system for inducing an electric field in a conducting medium, especially for medical applications. The system according to the invention induces a flow of electric current through objects located in the conducting medium (7), which may have shapes that are complex or change with time, and has a medical application consisting in a complete or partial nerve impulse block. The system for inducing an electric field in the conducting medium (7) comprises at least two component cores (2), whose magnetization is configured to be changed independently by a change of electric currents flowing through windings (5) that are wound around them, and a toms-shaped encasement (3) whose outer surface is electrically non-conductive, wherein the component cores (2) are situated inside the encasement (3) and encircle its opening, and the encasement (3) is situated inside the conducting medium (7).

Abstract: The invention relates to a field of biochemistry, and more precisely to a method of isolation, purification, and/or concentration of nucleic acids, in particular from biological samples, which is performed in flow within a conduit, and comprises steps of nucleic acid binding on a bed, bed washing and elution of the bound nucleic acids. The invention relates also to devices and systems for nucleic acid isolation according to this method.
