FIG. 1 is a schematic illustration of an implanted medical device and its relative position within a human body. The medical device ICM100 is implanted in a subcutaneous region of a human body 101. If the medical device is an ICD or pacemaker, the implant site is an atrium or ventricle within the heart, and the determination of a particular implant site is related to the number of medical devices implanted. The types of implantation are classified according to the number of implanted medical devices: single-cavity, double-cavity and three-cavity types. If the implantation type is a single-cavity implantation type, the implantation position is the right ventricle; if the double-chamber implantation type is adopted, one is implanted in the right atrium and the right ventricle respectively; if the three-cavity implantation type is adopted, the right ventricle, the right atrium and the left ventricle are implanted one by one. The ICM has sensing function to the human body electrocardiosignal and has no treatment function; while ICDs have not only a sensing function but also a therapeutic function on cardiac electrical signals. The ICM is typically implanted using a syringe, and in the clinic, a scalpel, syringe, and ICM are mated. When the device leaves a factory, the scalpel, the ICM and the injector are matched for use.
