Abstract

The invention discloses a rechargeable implantable medical device. The device comprises a casing, a battery arranged in the casing, and a coil which is used for receiving charging energy for the battery. A printed circuit board assembly and a shield layer are arranged in the casing. The printed circuit board assembly is arranged between the battery and the coil. The shield layer is arranged between the printed circuit board assembly and the coil. Cooling fins are arranged on one side, which is close to the coil, of the casing. According to the rechargeable implantable medical device, the speed at which the temperature of the casing rises to a highest temperature point is decreased during a charging process, which enhances the temperature experience of a user.

Description

technical field [0001] The invention relates to a rechargeable implanted medical device, in particular to a rechargeable implanted medical device with a heat dissipation structure that can be implanted inside a human body. Background technique [0002] There are many types of implanted medical devices, such as pacemakers and spinal cord stimulators, implanted neurostimulators, and more. Implantable medical devices are generally equipped with external control devices, and information is exchanged between the two through two-way wireless communication. [0003] In the prior art, the implantable medical device uses battery power to send out stimulation pulses of a specific frequency to provide long-term stimulation to specific targets, thereby improving the patient's symptoms. However, implantable medical devices powered by primary batteries are generally more expensive and often have a shorter lifespan. The main factor that limits the life of implantable medical devices is t...
