摘要： An improved method of weldbonding utilizing inclusion bodies, placed directly between materials to be bonded or included in a weldbonding adhesive. The inclusion bodies maintain a gap between the materials to be welded which provides a gas releasing egress route to disperse the gas and gaseous byproducts produced during welding. This egress route substantially prevents the gases and gaseous byproducts from being expelled through the weld pool and the resultant degradation of the quality of the weld pool, particularly with coated materials, partial penetration welds, and such materials as 6000 series aluminum. The method further comprises an optional step of including a crack-reducing additive, applied either directly to the materials to be welded or included in the adhesive. A laser weldbonding embodiment may use a plurality of phased heat cycles to reduce weld imperfections, and enhance the effects of the adhesive and optional crack-reducing additive.

摘要翻译： 一种改进的使用包含体的焊接方法，其直接放置在待粘合的材料或包含在焊接粘合剂中。 包合体在待焊接的材料之间保持间隙，其提供气体释放出口路径以分散气体和在焊接期间产生的气体副产物。 该出口路线基本上防止气体和气体副产物通过熔池排出，并导致熔池质量的下降，特别是涂覆材料，部分渗透焊缝以及6000系列铝等材料。 该方法还包括任选的步骤，包括直接施加到待焊接材料或包含在粘合剂中的抗裂减添加剂。 激光焊接实施例可以使用多个相位热循环来减少焊接缺陷，并且增强粘合剂和任选的抗裂附加剂的效果。

摘要： The present invention is an apparatus and method for making a polymer patterned electrode for cardiac pacing and sensing. The electrode surface includes a polymer overlayed on an electrode. The polymer layer is patterned to form an electrode surface consisting of a polymer and a conductive metal surface. The electrode can be made of a high or low impedance electrode by changing the conductivity of the polymer. Furthermore, the electrode surface texture can be optimized with a micro pattern that may enhance the biocompatibility. The polymer may be conductive or insulative.

摘要： A lead assembly for an implantable medical device. The lead assembly comprises a lead body having a first portion and a second portion. The first portion is adapted for coupling to a pulse generator and the second portion is adapted for implantation in or near a heart. First and second co-radial conductive coils are positioned within the lead body and electrically isolated from each other. The first and second conductive coils include a first and second number of coil turns and the first number is substantially equivalent to the second number. A ring electrode is located at the second portion and a tip electrode is located distal to the ring electrode and coupled to the second conductive coil. The first conductive coil extends past the ring electrode and transitions to a non-coiled region, which extends back to and couples to the ring electrode.
