Abstract

The invention discloses a feedthrough filter, a manufacturing method thereof, and an implantable electrical stimulator. The feedthrough filter includes a feedthrough connector and a filter attached tothe feedthrough connector, wherein the feedthrough connector includes a ferrule, a feedthrough member, and at least one signal line; the ferrule is provided with an upper edge, a lower edge and an inner hole; the upper edge and the lower edge form an annular mounting groove for assembling with the outer side surface of the ferrule; the inner hole seals the feedthrough member; the inner hole and the feedthrough member have the identical shape and are matched and connected to each other; the feedthrough member is composed of a single or combined implantable ceramic or glass material, and formsa sealing body with the ferrule and the at least one signal line; and the at least one signal line passes through a first through hole in the feedthrough member for connecting an internal interface terminal and an external terminal of an electrical stimulator. By attaching the filter to the feedthrough connector, the feedthrough filter can satisfy the demand of a feedthrough connector and also hasfiltering performance.

Description

technical field [0001] The invention relates to the technical field of implantable medical equipment manufacturing, in particular to a feedthrough filter for an implantable electrical stimulator, a manufacturing method thereof, and an implantable electrical stimulator. Background technique [0002] Feedthrough connectors are also widely used in implantable medical devices, especially implantable medical devices with electrical stimulation functions (electrostimulators). Feedthrough connectors are currently used in implantable medical devices such as cardiac pacemakers, deep brain stimulators, and spinal cord stimulators. Known implantable electrical stimulator systems generally include a pulse generator implanted in the body, extension wires and electrodes, and an external control device. The signal sent by the pulse generator is transmitted to the electrode through the feedthrough connector and the extended wire to stimulate the target tissue to achieve the purpose of elec...
