Implementing implantable sensors which are robust enough to maintain long term functionality inside the body remains a significant challenge. The ideal implantable sensing system is one which is simple and robust; free from batteries, telemetry, and complex electronics. We have developed an elementary implantable sensor for orthopaedic smart implants. The sensor requires no telemetry and no bat...

The first clinical application of the first-generation pulsatile implantable left ventricular assist system (LVAS) was in the mid 1980 s as a bridge to transplantation and contributed to an advancement of this field from a clinical experiment to an established therapeutic option for treating advanced heart failure patients. However, there have been technological limitations that have surfaced a...

Implantable devices are currently used regularly for chronic pain relief, cardiac pacemakers, arterial infusion for cancer and insulin delivery. A MEMS based implantable drug delivery system (IDDS) integrating a subcutaneous reservoir, an in plane silicon pump and associated circuitry for local or centralized delivery of therapeutic agents for chemotherapy is proposed. System configurations, fl...

BACKGROUND: Totally implantable venous access devices are widely used for infusion of chemotherapy or parenteral nutrition. Device associated complications include technical operative problems, infections, paravasal infusions and catheter or punction chamber dislocation. CASE PRESENTATION: We present the case of a 49-year-old patient with the rare complication of a intrapulmonal catheter disloc...

Conductive hydrogels are promising material candidates in artificial skin and muscles, flexible implantable bioelectronics, tissue engineering.

An implantable biosensor consisting a sensing element an electronic circuits receiving signals from sensing elements to produce data. The innovative development process which concludes implantable biosensors for continuous analysis of metabolites is an area of sustained, quantitative and technological interest. Nanotechnology is the promising field of research because of its tendency to revolut...

A method of recharging implantable biosensors based on solar radiation is proposed. Firstly, the models of the proposed method are developed. Secondly, the recharging processes based on solar radiation are simulated using Monte Carlo (MC) method and the energy distributions of sunlight within the different layers of human skin have been achieved and discussed. Finally, the simulation results ar...

We describe the case of a patient with hypertrophic cardiomyopathy who had recurrent syncopal episodes, the cause of which remained unexplained despite a thorough evaluation. Two years after his first evaluation, an implantable loop recorder revealed asymptomatic episodes of advanced second degree atrioventricular block while the patient was awake. Although a permanent pacemaker was implanted, ...

ASSOCIATED INFECTION OF MEDICAL IMPLANTS J.-H. Lee, H. Wang, M. Libera, and W.Y. Lee Stevens Institute of Technology, USA ABSTRACT This paper reports the exploration of microfabricated bioreactors (“microreactors”), as new in vitro tools for studying the complexity of biofilm-associated infection of implantable medical devices. We designed, fabricated, and evaluated microreactors in an iterativ...
