in the past, medical device design always was performed with medical engineers, technicians and physicians in all design stages and the industrial design role was pale in this field. today the industrial design responsibilities in designing of these devices are considered increasingly. the industrial design role in medical device design was investigated in two fields. first are aesthetic and it...

Background: Peritoneal dialysis (PD) is an efficient alternative for hemodialysis. Removal of waste metabolites and excess water from the blood circulation are the two main tasks done during dialysis. These are done by using a filter; in PD, the naturally semi-permeable peritoneal membrane acts as the filter. Automated PD machines control intelligently the operations to enhance the efficiency a...

We consider a device-to-device (D2D) aided multicast channel, where a transmitter wishes to convey a common message to many receivers and these receivers cooperate with each other. We propose a simple computationally efficient scheme requiring only statistical channel knowledge at transmitter. Our analysis in general topologies reveals that, when the number of receivers K grows to infinity, the...

background the forced oscillation technique (fot) is a non-invasive means of measuring respiratory resistance and reactance. we tested our hypothesis that endotracheal intubation would cause more substantial preoperative increases in fot parameters than a supraglottic airway device (sgd). methods forty patients requiring general anesthesia and mechanical ventilation for transurethral bladder tu...

today, congenital heart diseases may be treated without surgery through advances in interventional cardiology. however, complications such as infection and thrombus formation may develop due to foreign materials used during these procedures. surgical intervention may be required for the removal of the device utilized for the procedure. in this case report, we present the surgical treatment of a...

a secundum atrial septal defect is the most common congenital heart defect. transcatheter treatment of secundum atrial septal defects is a popular and less invasive alternative to surgery. procedural complications may occur in a wide spectrum, particularly device embolus as the most emergent one, but luckily they do not commonly occur in the clinical setting. mortality from adverse events relat...
