20110015686 | SEALING OF AN IMPLANTABLE MEDICAL DEVICE - A method of adhering a protective layer applied to a substrate region of an implantable medical device (IMD) to form a covered substrate region. The method includes obtaining the IMD, depositing an intermediate layer on a portion of the substrate region of the IMD such that the intermediate layer binds to the portion of the substrate region to create a modified substrate region, and depositing the protective layer after depositing the intermediate layer onto the intermediate layer and adhering the protective layer to the intermediate layer. In an embodiment of the present invention, this method enhances the sealing characteristics of the protective layer by, for example, reducing the likelihood of delamination of the protective layer from the IMD relative to IMDs prepared by certain other methods. | 01-20-2011 |
20110056725 | INSULATED CONDUCTIVE ELEMENT HAVING A SUBSTANTIALLY CONTINUOUS BARRIER LAYER FORMED VIA RELATIVE MOTION DURING DEPOSITION - Coating an elongate, uncoated conductive element with a substantially continuous barrier layer. An uncoated conductive element is around a frame comprising spaced supports. During deposition, the relative position of the conductive element to the frame is adjusted so that all sections of the conductive element are physically separated from the supports for a time that is sufficient to form a desired coating of barrier material on all sections of the conductive element. | 03-10-2011 |
20110056729 | INSULATED CONDUCTIVE ELEMENT HAVING A SUBSTANTIALLY CONTINUOUS BARRIER LAYER FORMED THROUGH CONTINUOUS VAPOR DEPOSITION - A continuous vapor deposition system for coating an elongate, uncoated conductive element with a substantially continuous barrier layer. The system comprises an internal deposition chamber configured to have a section of the conductive element extend there through; a vapor supply system connected to the internal deposition chamber configured to provide a barrier material to the internal deposition chamber, wherein the barrier material is deposited on the section of the conductive within the internal deposition chamber to form a substantially continuous barrier layer; and a guide system positioned adjacent to the first deposition chamber configured to maintain tension in the section of the conductive element in the internal deposition chamber to control movement of the conductive element through the internal deposition chamber. | 03-10-2011 |
20110127243 | ELECTRODE CONTACT CONTAMINATE REMOVAL - Manufacturing an electrode assembly comprising forming an intermediate assembly comprising a carrier member having one or more electrode contacts embedded therein, the surface of the electrode contacts having a layer of carrier member material thereon; removing the layer of carrier member from the surface of the one or more electrode contacts, wherein a residual amount of the carrier member material remains on the surface of at least one of the electrode contacts; and substantially removing the residual carrier member material from the surface of the at least one electrode contact so as to increase the effective surface area of the at least one electrode contact. | 06-02-2011 |
20120143284 | IMPLANT STIMULATION DEVICE - An implantable stimulation device is disclosed which provides for reduced power consumption when compared with bipolar stimulation and better stimulation performance when compared with monopolar stimulation. Implantable stimulator devices use less power in monopolar stimulation mode than that of bipolar stimulation but stimulation performance is greater when using bipolar stimulation. The device comprises circuitry capable of simultaneous stimulation between a reference electrode and an electrode of a stimulation array and between electrodes of the stimulation array, the ratio of current to the reference electrode and array electrodes being selectable. | 06-07-2012 |
