1. A method of connecting a first wire comprising a first longitudinal axis to a conductive piece, the method comprising:
- positioning the first wire and the conductive piece such that the first wire and the conductive piece contact;
resistance welding the first wire and the conductive piece together; and
energy beam welding the first wire and the conductive piece together, wherein energy beam welding the first wire and the conductive piece together comprises;
aiming an energy beam at an edge of the first wire such that a portion of the energy beam is tangent to the edge.

Abstract
Methods of making an implantable pulse generator are disclosed herein. The implantable pulse generator can include a body defining an internal volume and a plurality of wires extending from out of the internal volume of the body. Some of these wires can be connected, either directly or indirectly to a lead via a welded joint. The welded joint can be created by first resistance welding and then laser welding some of the wires to a connector.
