Patent number: 10363411Abstract: A medical microelectrode includes an elongate electrode body including a tip section, a main body section and, optionally, a coupling section. The tip section, the main body section and, optionally, the coupling section are embedded in a first electrode matrix element, which is substantially rigid, biocompatible and soluble or biodegradable in a body fluid. Additionally the microelectrode includes a dissolution retarding layer on the first electrode matrix element and/or a second electrode matrix element disposed between the first electrode matrix element and the electrode. Upon dissolution or biodegradation of the first electrode matrix element a drug comprised by the first electrode matrix element or the second electrode matrix element is released into the tissue. Also disclosed are bundles and arrays of the electrodes and their use.Type: GrantFiled: June 13, 2017Date of Patent: July 30, 2019Assignee: NEURONANO ABInventors: Fredrik Ek, Nils Danielsen, Jenny Eriksson Linsmeier, Per Petersson, Jens Schouenborg

Patent number: 6905628Abstract: In etching, an etchant (4) for etching of a substrate (1) is applied in a given pattern. Before etching, a resist layer (2) is applied to the substrate (1) in said pattern to define at least one exposed portion (3) of the substrate (1). In order to minimize under etching, a passivating substance is arranged, before etching, on the substrate (1) to also define said pattern, i.e., at the periphery of the exposed portion (3). The passivating substance is such as to form, during etching, an etch-protecting compound at the periphery.Type: GrantFiled: September 20, 2001Date of Patent: June 14, 2005Assignee: Obducat AktiebolagInventors: Bjarni Bjarnason, Per Petersson

Patent number: 6656341Abstract: In a method of etching a substrate having a surface layer of conductive material, a circuit pattern is transferred to the surface layer in a central surface area portion of the substrate by electrochemical etching. To prevent excessive current densities from forming at the periphery of the central surface area portion during the etching step, a frame adapted to attract electrical field is provided adjacent to the central surface area portion. The frame can be part of a separate frame element which is placed on the substrate before the etching step, or be incorporated in a resist coating on the substrate. The frame can be transferred to the resist coating by any suitable means, for example by photolithographic exposure through a mask with a suitable frame pattern. Alternatively, the frame can be incorporated in a prefabricated substrate element, to which the circuit pattern is transferred in the etching step.Type: GrantFiled: September 18, 2001Date of Patent: December 2, 2003Assignee: Obducat AktiebolagInventors: Per Petersson, Mikael Gustavsson, Jenny Sjöberg, Bin Xie, Bjarni Bjarnason, Gust Bierings, Göran Frennesson
