Connection structure and connection method of implantable pulse generator and pulse generator

Abstract

The application discloses a connecting structure and method of an implantable pulse generator and the pulse generator. The connecting structure is formed between a feedthrough lead and an antenna. The antenna has an antenna lead-out end which is columnar. The diameter of the feedthrough lead is substantially the same as that of the antenna lead-out end. The antenna lead-out end is arranged along the length direction of the feedthrough lead. The head of the antenna lead-out end and the head of the feedthrough lead are respectively provided with a first bending part and a second bending part. The first bending part and the second bending part are hooked and connected through at least one laser spot welding. The application can better overcome the axial and radial tension through the hooking and welding mode, improve the stability of the connection, and reduce the possibility of falling off, thereby solving the problems that the connection between the antenna and the feedthrough lead of the implantable pulse generator is unstable and easy to fall off in the prior art.
