20110071627 | DEVICE FOR REVERSIBLY ATTACHING AN IMPLANT IN AN EYE - 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. | 03-24-2011 |
20110152969 | EXTRAOCULAR EPIRETINAL IMPLANT - The object of providing a visual prosthesis in the form of a retinal implant, which is distinguished by the least possible space requirement inside the eye, is achieved according to the present invention by a visual prosthesis having an intraocular implant and an extraocular implant, which supplies the intraocular implant with energy and controls it. The visual prosthesis according to the invention therefore offers the advantage that virtually all the electronic components, which do not necessarily need to be accommodated with the intraocular implant inside the eye, can be arranged outside the eyeball, for example on the sclera. In this way, the space requirement of the stimulation system inside the eye is reduced and the operative intervention for implanting the stimulation system inside the eye is kept as small as possible. The present invention furthermore discloses a bidirectional inductive interface between an extracorporeal part of the visual prosthesis and an intracorporeal part, comprising the intraocular and extraocular implants, via which an current supply and bidirectional data transmission can be carried out. | 06-23-2011 |
20130131797 | RETINAL IMPLANT AND VISUAL PROSTHESIS INCORPORATING SUCH AN IMPLANT - A system for generating artificial vision in a subject, comprising: an image capture means for capturing an image from a surrounding environment; an image processing means for processing the image and converting the image into an image signal; and a retinal implant or stimulation device ( | 05-23-2013 |
20150080996 | DEVICE WITH FLEXIBLE MULTILAYER SYSTEM FOR CONTACTING OR ELECTROSTIMULATION OF LIVING TISSUE CELLS OR NERVES - 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. | 03-19-2015 |
