Embodiment Construction

[0033] figure 1 An implantable medical device 100 is shown according to one example. The implantable medical device 100 includes a hermetically sealed metal housing 110 with an attached head 120 . Head 120 includes one or more ports 122 to receive terminal pins 124 of implantable lead 130 . Guide 130 is configured, for example, to deliver pacing pulses, defibrillation energy, or cardioversion therapy to the heart. Implantable medical device 100 may be implanted in a surgically formed pouch or other desired location on a patient's chest. Implantable medical device 100 generally includes electronic components for performing signal analysis, processing, and control. Implantable medical device 100 may include a power source such as a battery, a capacitor, and other components housed within housing 110 . Implantable medical device 100 may include a microprocessor mounted to a circuit board or flexible circuit to provide processing and evaluation to respond to heart rhythms incl...

Abstract

This document describes an implantable medical device including a housing. Electronic components are located within the housing, and a non-metallic hydrogen getter is located within the housing.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority under 35 U.S.C. §119(e) of U.S. Provisional Patent Application Serial No. 61 / 989,720, filed May 7, 2014, which is hereby incorporated by reference in its entirety. Background technique [0003] A pulse generator (implantable medical device or IMD), such as a cardiac rhythm management device, may include a sealed housing containing multiple electronic and electrochemical components. Various sources of hydrogen such as heating insulation or circuit boards, electrochemical systems such as batteries or capacitors, and trapped hydrogen from previous processing or fabrication can allow the build-up of hydrogen in the device. [0004] Hydrogen has been shown to have a potentially harmful effect on electronic components such as capacitors. For example, capacitors may experience an increase in leakage current. US Patent 4,127,134 describes a pacemaker with a palladium metal hydrog...
