摘要： For an implantable medical devices, a system is provided for welding electrically conductive ribbon, typically stainless steel, to electrically conductive wire, typically platinum, the melting point of steel being substantially lower than that of platinum. An aperture is formed in the ribbon having an opening smaller than that of the wire. The ribbon is engaged with the wire such that the aperture is generally coextensive with the wire. Thereupon, a pulse laser beam is directed transversely of the ribbon through the aperture and onto the wire to simultaneously melt the wire and the ribbon and to create a homogeneous mix of the molten steel and platinum in the region surrounding the aperture. Thereafter, operation of the laser beam is discontinued to allow solidification and thereby achieve a welded connection between the ribbon and the wire.

摘要： Particularly applicable to implantable stimulation devices, a system is provided for laser-welding an electrically conductive elongate member, typically a lead, or elongate member, interconnecting operating components of a stimulation device. A bore is formed in a termination component for the slidable reception of the elongate member. Also formed in the termination component is an aperture in communication with the bore and having an axis which extends in a direction transverse that of the axis of the bore. The elongate member is positioned so it extends through the bore in the termination component and is thereby coplanar with and intersects the axis of the aperture. Thereupon, a laser beam, which may be from a pulse laser, is directed transversely of the elongate member through the aperture in the termination component and onto the elongate member to simultaneously melt the elongate member and the termination component in the region of the aperture and create a homogeneous mix of the molten material of both the elongate member and the termination component within the aperture. Then, operation of the laser beam is discontinued to allow solidification of the homogeneous mix of the molten material within the aperture to thereby achieve a welded connection between the elongate member and the termination component. The aperture in the termination component must be large enough to allow the laser beam to pass therethrough yet small enough to allow the melt of the rim of the aperture and the elongate member simultaneously.
摘要翻译： 特别适用于植入式刺激装置，提供了一种用于激光焊接导电细长构件（通常为引线或细长构件）的系统，其互连刺激装置的操作部件。 在终端部件中形成孔，用于可滑动地接收细长构件。 还在端接部件中形成的是与孔连通并具有沿垂直于孔的轴线的方向延伸的轴线的孔。 细长构件被定位成使得其延伸穿过终端部件中的孔，并且由此与孔的轴线共面并与之相交。 因此，可以来自脉冲激光器的激光束通过终端部件中的孔横向地指向细长构件并延伸到细长构件上，以在孔的区域中同时熔化细长构件和端接构件，并且 在孔内产生细长构件和终端组件的熔融材料的均匀混合物。 然后，中断激光束的操作，以允许熔融材料在孔内的均匀混合物固化，从而实现细长构件和端接构件之间的焊接连接。 终端部件中的孔径必须足够大，以允许激光束穿过其中，但是足够小以允许孔的边缘和细长构件同时熔化。
