20100010604 | PASSIVATED METAL CONDUCTORS FOR USE IN CARDIAC LEADS AND METHOD OF PREPARING THE SAME - An implantable medical device is made more durable and long-lasting by providing a passivating layer or film on at least a portion of a metal or metal alloy outer surface of an electrically conducting device. An insulating layer is placed on the passivating layer or film. The passivation can be a chemical passivation, and is preferably an acid treatment. | 01-14-2010 |
20120290060 | METHOD OF PRODUCING A PROXIMAL CONNECTOR END OF AN IMPLANTABLE LEAD - A connector for an implantable medical lead that is electrically and mechanically connectable to an implantable medical device, has a connector pin made of a first conducting material. A tubular insulator made of an insulating material concentrically surrounds at least a portion of the pin. A connector ring made of a second conducting material is concentrically positioned around at least a portion of the insulator. The insulator is connected to the connector ring by spark plasma sintering in the case of an active fixation lead, and is connected to the ring and the pin by spark plasma sintering in the case of a passive fixation lead. | 11-15-2012 |
