Patent number: 11881325Abstract: Various embodiments of a nuclear radiation particle power converter and method of forming such power converter are disclosed. In one or more embodiments, the power converter can include first and second electrodes, a three-dimensional current collector disposed between the first and second electrodes and electrically coupled to the first electrode, and a charge carrier separator disposed on at least a portion of a surface of the three-dimensional current collector. The power converter can also include a hole conductor layer disposed on at least a portion of the charge carrier separator and electrically coupled to the second electrode, and nuclear radiation-emitting material disposed such that at least one nuclear radiation particle emitted by the nuclear radiation-emitting material is incident upon the charge carrier separator.Type: GrantFiled: October 19, 2020Date of Patent: January 23, 2024Assignee: Medtronic, Inc.Inventors: Andreas Fenner, David A. Ruben, Anna J. Malin, Paul F. Gerrish, Bruce C. Fleischhauer, Larry E. Tyler

Patent number: 8543190Abstract: A device includes a flexible substrate, N coiled conductors, and a plurality of folding regions. The N coiled conductors are deposited on the flexible substrate and connected in series by conductive interconnects. N is greater than 1. Each of the folding regions is defined by a separation distance between adjacent ones of the N coiled conductors. The conductive interconnects traverse the folding regions between the N coiled conductors to connect the N coiled conductors in series. The flexible substrate is folded such that the N coiled conductors form a stack of N coiled conductors.Type: GrantFiled: July 30, 2010Date of Patent: September 24, 2013Assignee: Medtronic, Inc.Inventors: James R. Wasson, Clark B. Norgaard, Bruce C. Fleischhauer, Michael F. Mattes, Randal C. Schulhauser

Patent number: 8513120Abstract: The present disclosure relates to an implantable medical device. The implantable medical device includes a component comprising a first substrate bonded to a second substrate. A method for forming the component includes removing a first portion of tin (Sn) from gold tin (AuSn) through a halogen plasma. A first portion of gold (Au) is exposed in response to removing the first portion of the Sn. The first portion of the Au through a wet etch. A second portion of the Sn is exposed in response to removing the first portion of Au.Type: GrantFiled: April 28, 2011Date of Patent: August 20, 2013Assignee: Medtronic, Inc.Inventor: Bruce C Fleischhauer
