INTRODUCTION AND OBJECTIVES The authors summarize the findings of the Spanish Implantable Cardioverter-Defibrillator Registry for 2010 compiled by the Spanish Society of Cardiology Working Group on Implantable Cardioverter-Defibrillators. METHODS Members of the Spanish Society of Cardiology were prospectively surveyed; data were recorded voluntarily by each implantation team on one-page quest...

Many implantable medical devices contain sophisticated electronic circuits. Hermetic packaging is required to provide the implant’s electronic circuitry with protection from the harsh environment of the human body. This chapter provides a review of available hermetic sealing methods and their applications. General considerations of implantable medical device packaging are discussed. Various tes...

The microphone in a fully implantable hearing device (FIHD) is generally implanted under the skin covering the temporal bone. However, the implanted microphone can be affected by the skin, which causes both sound attenuation and distortion, particularly at high frequencies. As the degree of attenuation and distortion through the skin is severe, speech quality evaluation parameters are needed fo...

below, most of the patients undergoing heart transplantation are on some form of LVAD as BTT. At first, extracorporeal devices were the norm. Implantable devices were initially only used as part of clinical trials, but BTT therapy using an implantable LVAD, allowing treatment at home, is increasingly coming into use since medical insurance coverage became available for nonpulsatile implantable ...

BACKGROUND Vascular occlusion is a rare, but serious complication after kidney transplantation often resulting in graft loss. We therefore aimed to develop an experimental porcine model for stepwise reduction of the renal venous blood flow and to compare an implantable Doppler probe and microdialysis for fast detection of vascular occlusion. METHODS In 20 pigs, implantable Doppler probes were...

OBJECTIVE Implantable cardioverter-defibrillator has become the first-line therapy for prevention of sudden cardiac death. Controversial results still exist regarding the effectiveness of implantable cardioverter-defibrillator (ICD) in non-ischemic heart failure. METHODS The PubMed, Embase, and Cochrane Central databases were searched for randomized trials comparing implantable cardioverter-d...

Experiments were conducted to evaluate a silicon accelerometer as an implantable sound sensor for implantable hearing aids. The main motivation of this study is to find an alternative sound sensor that is implantable inside the body, yet does not suffer from the signal attenuation from the body. The merit of the accelerometer sensor as a sound sensor will be that it will utilize the natural mec...

Electronic article surveillance (EAS) systems are widely implemented in public spaces and can adversely affect the performance of pacemakers and implantable cardioverter defibrillators. The interaction between implantable devices and EAS systems is a serious problem that can be minimized through appropriate facility design. Careful facility design and employee education along with patient vigil...

BACKGROUND Inadvertent damage to leads for transvenous pacemakers, implantable cardioverter-defibrillators, and cardiac resynchronization therapy defibrillators is an important complication associated with generator-replacement procedures. We sought to estimate the incidence and costs associated with transvenous lead damage following cardiac implantable electronic device replacement. METHODS ...
