Problems solved by technology

A technical difficulty of this design lies in the machining of very small holes (eg 0.4mm diameter) around the diameter of the ceramic shell, since the shell is made of a very hard material
Another issue is the cost of machining such a small and precise hole as it must be ground with diamond tools

Embodiment Construction

[0048] Neurostimulation implants can be used to stimulate and / or measure electrophysiological signals. Examples of neurostimulation implants are cochlear implants such as figure 1 shown in .

[0049] A cochlear implant includes an inner portion 100 that is surgically implanted in a patient (eg, under the skin, on the skull) and an outer portion 120 that is attached over the implanted portion. exist figure 1 In the example shown, a cochlear implant includes an implantable sealed housing 101 and an external antenna 108 . Implantable sealed housing 101 includes electronic circuitry 102, receive / transmit antenna 103 and magnet 104 to hold outer portion 120 with antenna 108 in place. The external antenna 108 can thus communicate with the electronic circuit 102 implantable in the sealed housing. The antennas 103, 108 may be coils whereby magnetic energy and information may be passed from one coil to the other.

[0050] The design of the housing 101 is based on a body 105 made o...

Abstract

A cochlear implant includes a sealed housing (201) containing electronics (208) for at least stimulation or collection of data and at least one antenna (310) for communicating with an external device and a magnet (314)configured to hold the external device in proximity to the sealed housing. The sealed housing (201) includes an upper cover (203) being closest to the skin when the device is implanted, and a lower cover (206) that is hermetically connected to the upper cover. The lower cover includes an elevated region (210, 211), a recessed region (220), and at least one feedthrough element (204, 209) formed in the recessed region of the lower cover. The recessed region provides space for a lead to connect to the feedthrough element and protects it from shock and other environmental risks.

Description

technical field [0001] The present invention relates to the field of small connection ports, which are known in the art as feedthroughs and which can be used in subcutaneous active medical devices. The feedthrough may comprise a conductor placed in a small opening in an electrically insulating material. Background technique [0002] Many implantable devices use feedthroughs to connect a hermetically encapsulated electronics board to implanted devices such as measurement and / or stimulation electrodes and / or electromechanical actuators. The feedthrough includes an electrical connection between the hermetically closed housing and the exterior surrounded by insulating material, which enables electrical signals to be communicated between the environment and the sealed housing while maintaining the integrity of the sealed housing. [0003] The implantable shell can be made of titanium. In the case of titanium casings, the feedthroughs for the entire casing unit can be assembled ...
