Abstract

Disclosed is an implantable sacral nerve stimulator adopting a wireless percutaneous charging mode. The implantable sacral nerve stimulator comprises an implantable medical device and an external charging apparatus for charging the implantable medical device wirelessly, wherein the implantable medical device comprises two internal charging coils, namely, a first internal charging coil and a second internal charging coil; the external charging apparatus comprises two external charging coils, namely, a first external charging coil and a second external charging coil; and the first internal charging coil and the second internal charging coil are used for performing wireless charging on the implantable medical device alternately.

Description

technical field [0001] The present invention generally relates to an implantable medical system, and more particularly relates to a wireless percutaneous charging implantable medical system, and more particularly relates to a wireless percutaneous charging implantable sacral nerve stimulator. Background technique [0002] Implantable medical devices (IMDs) are implanted in a patient to monitor the patient's physical condition and / or deliver therapy to the patient. Power sources for implantable medical devices include non-rechargeable batteries and rechargeable batteries. Non-rechargeable batteries typically require replacement after a fixed period of time, and the surgery to replace the battery is painful and expensive for the patient. A rechargeable battery has the distinct advantage of being depleted or near depleted using a charging device located outside the patient. Typically, rechargeable batteries are recharged through an inductive coupling system. Specifically, an...
