The invention relates to a neural prosthesis, a neural prosthesis for use in the treatment of severed nerves and to a method for producing a neural prosthesis. Said neural prosthesis comprises a coupling element receptacle and at least one coupling element having a first and a second coupling section, wherein the coupling element is fixed by the coupling element receptacle, and wherein the first coupling section can be arranged on a first nerve region and the second coupling section on a second nerve region so that both nerve regions can be coupled by means of the neural prosthesis.

Neural prosthesis and method for producing a neural prosthesis

A wide-angle optical unit for ophthalmological implants in the eye includes a lens system arranged in a rotationally symmetrical manner about an optical axis and further includes at least two lenses that rest one on top of the other in a planar manner and which are made of materials having different optical refractive indices. In addition, the wide-angle optical unit includes an optical decoupling structure and a trailing lens arranged proximally with respect to the interior of the eye. The trailing lens is mounted around the optical decoupling structure.

In a sensor system for determining the control signal supplied to the ciliary muscles of an eye for adjusting the focal length of the lens of an eye, a contact element of an electrically non-conductive material and provided with sensors is disposed on the cornea of the eye so that the sensors are arranged in contact with an annular area of the cornea next to the ciliary eye muscles so as to be able to sense the focal adjustment signals supplied to the ciliary muscles and the sensed adjustment signals are supplied to a signal processing unit which provides a control signal to a lens system with adjustable focal length for adjusting the focal length thereof depending on the focal adjustment signals of the ciliary eye muscles.

Sensor system for determining the control signals activating ciliary muscles

An implantable system for restoring accommodation capacity includes at least one ring configured to be implanted in a ciliary sulcus and a capacitor with a first capacitor plate and a second capacitor plate. The first capacitor plate is arranged on an implantable ring and the second capacitor plate is connected to a capsular bag.

Implantable system for restoring accommodation capacity using internal energy

An implantable system for determining the accommodation requirement in an artificial accommodation system by optical measurement of the pupil diameter and the surrounding luminance, including at least one optical system, at least one data acquisition system that does not contact the ciliary muscle and measures a diameter of the pupil and luminance around at least one eye as a physical control signal for the accommodation requirement, at least one data processing system for generating an actuating signal for the optical system from the detected physical control signals or for the purpose of switching to the standby mode, at least one energy supply system, and at least one fixing system. The system has one sensor or a plurality of sensors with sensor elements for measuring the pupil diameter and the surrounding luminance.
