Implantable devices such as cardiac pacemakers, drug-delivery systems, and defibrillators have had a tremendous impact on the quality of live for many disabled people. To date, many devices have been developed for implantation into various parts of the human body. In this paper, we focus on devices implanted in the head. In particular, we describe the technologies necessary to create implantabl...

t-wave oversensing occurs when the counter starts giving dual beeps for every cardiac cycle instead of one. this usually happens when the monitoring lead displays a tall t wave, which is also sharp. r wave sensing algorithms of the devices do not sense t wave because the slow rate of the t wave is much less than that of the r wave. but the slow rate of t waves may change with time and also beca...

Abstract Background Totally implantable central venous access devices (ports) have been available for over 10 years, but have not been achieved widespread use in pediatric oncology patients. Ports facilitate the administration of chemotherapy in children with cancer. Materials and Methods In this study, early complications of implantable central venous access devices in children with diff...

Implantable Medical Devices In article number 2201973, Pyungwoo Yeon, Min-gu Kim, and co-workers demonstrate that reliability lifetime estimation of implantable medical devices (IMDs) is one the essential steps in their design development. Traditional leak tests are applicable to large cm-scale IMDs, they often destructive, laborious, costly. This paper presents an automated wireless accelerate...

Background: Dextrocardia is a congenital anomaly, which may have coexistent coronary artery disease (CAD), arrhythmias and conventional indications for device therapy. However, the implantation of transvenous leads can be technically challenging and the approach needs to be tailored to the patient's individual anatomy. Case presentation: A 54-year-old male with dextrocardia situs inversus and i...

One of the current trends in the rehabilitation of lower limb neuromuscular disabilities is to use fully or partially implantable systems based on Functional Electrical Stimulation (FES). In this paper, the conceptual design of a possible fully or partially implantable system with submillimiter size is presented. The system presents increased flexibility, adaptability and comfortability. Prelim...

Introduction A subcutaneous implantable cardioverter-defibrillator (S-ICD) is now being used as an alternative to a transvenous implantable cardioverter-defibrillator (TV-ICD). Because the location of the device in the body differs between S-ICD and TV-ICD, ICD-related complications need to be managed in a device-specific manner. Therefore, therapeutic strategies for infected wounds may differ ...
