In this paper we perform signal strength and channel impulse response simulations using an accurate human body model and we investigate the variation in signal loss at different RF frequencies as a function of position around the human body. It was observed that significant variations in received signal strength (RSS) occurred with changing position of the(More)
In most patients with an atrial septal defect or patent foramen ovale, a single defect of the interatrial septum may be closed with a single device. However, patients with multiple defects of the interatrial septum may require the use of multiple devices, which involves some technical challenges. We present 5 cases requiring 2 closure devices with clinical(More)
