Patent number: 8311606Abstract: 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.Type: GrantFiled: September 20, 2006Date of Patent: November 13, 2012Assignee: Cardiac Pacemakers Inc.Inventors: Xiangchun Jiang, Kevin J.

Patent number: 6932879Abstract: 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.Type: GrantFiled: August 13, 2002Date of Patent: August 23, 2005Assignee: Edison Welding InstituteInventors: Kevin J.
