The electrical conductor extends from a bond pad integral with integrated circuit at least partially through the package substrate. The electrical conductor functions as the conductive member that extends between the integrated circuit an electrode with which the integrated circuit is associated.Type: ApplicationFiled: June 8, 2012Publication date: December 27, 2012Inventors: John Janik, Rob Brindley, Edward Chia-Ning Tang, James Bernard Dunlop, JR., Leland Joseph Spangler

Patent number: 8271084Abstract: An earlier intrinsic activation and a later intrinsic activation of a right ventricle and a left ventricle are determined. This information is used for computing a biventricular pacing interval as a function of an interval from a pacing energy delivered to a ventricle corresponding to the later intrinsic activation and a depolarization sensed in a ventricle having earlier intrinsic activation, the depolarization evoked in response to the pacing energy.Type: GrantFiled: October 27, 2008Date of Patent: September 18, 2012Assignee: Cardiac Pacemakers, Inc.Inventors: Yinghong Yu, Jiang Ding

Publication number: 20120232629Abstract: A lead for use in Deep Brain Stimulation (DBS) and similar applications has a rigid lead tip with multiple electrodes thereon. The electrodes are formed by coating a lead tip core with a conductive material; selectively removing the conductive material to define the electrodes and conductive tracks leading therefrom; and then applying a layer of insulating material over the tracks to leave the electrodes exposed. Terminals are also left exposed on the tracks for connection to energy supply and/or data transmission lines. Such lines are preferably provided on or within a flexible lead body connected to the lead tip.Type: ApplicationFiled: February 23, 2012Publication date: September 13, 2012Inventors: Frank Bloemer, Erhard Flach

Patent number: 8249725Abstract: Methods, apparatus, and systems are provided to stimulate multiple sites in a heart. A controller senses electrical activity associated with sinus rhythm of the heart. A signal generator is configured to generate an electrical signal for stimulating the heart. Based on the electrical signal, a distributor circuit then distributes the stimulating signals, such as pacing pulses, to a heart. The distributor circuit may vary the delay time between stimulating signals, inhibit a stimulating signal, trigger application of a stimulating signal, or vary the characteristics, such as the pulse width and amplitude, of a stimulating signal.Type: GrantFiled: May 8, 2007Date of Patent: August 21, 2012Assignee: Mirowski Family Ventures, L.L.C.Inventor: Morton M Mower
