The object,—to create a printed circuit board for an implant having improved properties in connection with the electrical contacting via the contact points of the conductor tracks on the printed circuit board,—is achieved, according to the present invention, by means of a device for contacting and/or electrostimulation of living tissue cells or nerves with having a printed circuit board having with at least one contact point for electrical contacting, the printed circuit board encompassing comprising a flexible multilayer system with at least one conductor track. In accordance with the invention, the contact points for the conductor track in the multilayer system are galvanically reinforced. To this end, a galvanically reinforced layer is grown onto the already preprocessed contact point, for example by means of a galvanic process. By virtue of the application of one or more additional material layers onto the contact points of the conductor tracks, these latter are mechanically more stably anchored in the printed circuit board in mechanically more stable manner and hence become more reliable in their function.

The object of providing a device for reversibly attaching an implant to an eye, with which the implant can be attached in a simple way to the eye and can if necessary be detached or removed from the eye, is achieved according to the present invention by means of a device for attaching an implant by means of a pin that comprises a substantially elongated shaft, wherein the implant includes an implant film for contacting living tissue or nerves in the visual system of the eye and the implant film has an opening through which the shaft of the pin can be at least partially inserted, characterised in that the device includes a holding element that can be arranged on the shaft of the pin so that the holding element engages on the shaft of the pin and is fixed in an attachment position to the pin. By means of the device according to the invention the implant is on the one hand reliably attached, but can if necessary be detached from the retina by removing the holding element or retainer, wherein the pin anchored in the eye does not have to be removed at the same time, but can be re-used. Damage or injury to the tissue of the eye that would otherwise be associated with the removal of the pin can thereby also be avoided.

The task of providing a device which makes it possible for the natural visual faculty of a partially vision-impaired person to be restored or supported as realistically as possible by means of a visual aid or visual prosthesis is achieved with the visual aid according to the invention in that, beyond the pure acquisition of a two-dimensional image, additional information is included in the image processing. For this purpose, a visual aid system is proposed which, during the reproduction of the processed image, visualizes additional information regarding the spatial position and/or specific attributes of objects in the acquired image which is associated with objects in the acquired image. The present invention thus affords the advantage that a three-dimensional image of the current environment of the user can be acquired owing to the fact that the image visualized to the user by the visual aid system according to the invention comprises additional information, for example, about the relative distance of the objects contained in the image and a depth-selective representation of the acquired image can thus be achieved.

摘要:
Retinal prostheses are configured to apply retinal stimulus signals based on retinal cell classification such as cell types or cell clusters identified based on retinal cell signals. Cell types are identified based on spontaneous or induced retinal electrical signals and analyzed based on temporal patterns of electrical activity, spatio-temporal voltage waveforms, and signal correlations that can be obtained from temporal spike patterns. Cell type indications are stored, and a signals are applied to the retina based on the stored cell type indications.

The present invention relates to a microelectronics element, such as an optical receiver element, for a medical implant device to be implanted in the human or animal body, particularly for a retinal implant device. The microelectronics element comprises a functional unit including application specific microelectronics, such as a photodiode, for performing a function in the medical implant device, and rectifier means adapted for converting an AC supply voltage into a DC voltage. The DC voltage provided by the rectifier means, or an operating voltage derived from the DC voltage, is configured to be supplied to the functional unit. Further, the functional unit and the rectifier means are integrated on a common semiconductor substrate and configured such that the rectifier means isolates the microelectronics element from application of an external DC supply voltage. The invention also relates to a medical implant device, such as a retinal implant, which incorporates such a microelectronics element.
摘要:
A power supply for a retina implant at least partly located in the interior of a patient's eye is described. The power supply comprises a first transmission coil (4, 23), a second transmission coil (5, 24). The power supply further comprises a signal generation unit adapted for generating a first high frequency signal and a second high frequency signal, and for applying the first high frequency signal to the first transmission coil and the second high frequency signal to the second transmission coil, the second high frequency signal being phase shifted relative to the first high frequency signal. The first transmission coil is adapted for transmitting the first high frequency signal, and the second transmission coil is adapted for transmitting the second high frequency signal.
