Central vein stenosis is a well-documented consequence of cardiovascular implantable electronic devices. In hemodialysis patients, where preserving venous real estate is crucial, use of subcutaneous implantable cardioverter-defibrillators (S-ICDs) remains controversial. We present a novel approach for implanting an S-ICD in a patient with endstage renal disease, central venous stenosis, and pre...

Implantable drug-delivery systems provide new means for achieving therapeutic drug concentrations over entire treatment durations in order to optimize drug action. This article focuses on new drug administration modalities achieved using implantable drug-delivery systems that are enabled by micro- and nano-fabrication technologies, and microfluidics. Recent advances in drug administration techn...

Portable implantable medical device systems are playing a larger role in modern health care. Increasing attention is now being given to the wireless control interface of these systems. Our position is that wireless security in portable implantable medical device systems is just a part of the overall system security, and increased attention is needed to address low-tech security issues.

gap resonator coil; B) a loop-gap resonator implantable coil coated with PDMS; and C) a surface coil. Each coil contains two tuning capacitors and a decoupling circuit that includes a hand-wound inductor and Schottky anti-parallel diodes. Development of a Receive-Only Inductively-Coupled RF Coil System to Enhance H NMR Localized Spectroscopy to Monitor an Implantable Bioartificial Construct at ...

An infrared (IR) transcutaneous remote control was designed for use in the totally implantable middle ear system. Considering the IR reflection, absorption and scattering effect of the skin, the required IR radiant intensity is calculated. After we have implemented the designed control, the transcutaneous operation experiment was carried out using a porcine skin. key words: implantable middle e...

Stored atrial and ventricular electrograms retrieved from dual chamber implantable defibrillators facilitate the diagnosis of arrhythmias. This case also illustrates the usefulness of programmed atrial and ventricular stimulation for noninvasive rhythm diagnosis in patients with a wide QRS tachycardia and an implantable defibrillator.

BACKGROUND The Cook-Swartz implantable Doppler system was introduced at the Uppsala University Hospital to ease free flap monitoring and improve salvage rates by an earlier detection of vascular compromise. The aim of the current analysis was to investigate whether the system indeed improved the salvage rate of revisions. METHODS All cases that needed revision among a consecutive series of pa...

BACKGROUND Studies of cardiac resynchronization therapy in addition to an implantable cardioverter defibrillator in patients with mild to moderate congestive heart failure had not been shown to reduce mortality until the recent RAFT trial (Resynchronization/Defibrillation for Ambulatory Heart Failure Trial). We performed a meta-analysis including the RAFT trial to determine the effect of cardia...

Semi-implantable transcutaneous bone conduction devices are treatment options for conductive and mixed hearing loss (CHL/MHL). For counseling of patients, realistic simulation of the functional result is desirable. This study compared speech recognition in noise with a semi-implantable transcutaneous bone conduction device to external stimulation with a bone conduction device fixed by a headban...

Controlled drug through diffusion and activation-based drug delivery devices have become commercially feasible due to converging technologies and regulatory accommodation. Combination products constructed using implantable technology offer revolutionary opportunities to address unmet medical needs related to dosing. These products have the potential to completely control drug release, meeting r...
