Submillimetric precision is essential for stereotactic neurosurgical procedures. However, accuracy of standard neuro-surgical procedures such as navigated biopsies and shunts is currently limited due to manual alignment of the biopsy needle or manual placement of the shunt catheter. The aim of this study is to evaluate the feasibility and accuracy of a novel robotic positioning device for stere...

totally implantable venous access devices (tivad) or implantable catheter ports are devices which can be implanted subcutaneously. they enable prolonged and repeated access to the vascular system, into the peritoneal cavity or intravertebral space. this device is particularly useful for repeated medical injection, for blood sampling or transfusion of blood and blood derivatives and for total pa...

device-associated nosocomial infection is a significant part of nosocomial infection and can cause the majority of its mortality, morbidity, extra lengths of hospital stay and cost. in a 13-year review, the online database was searched for full articles to find research on epidemiology of device-associated nosocomial infection in pediatric and neonatal wards. twenty two papers were included fiv...

statement of problem: snoring is the most common sleep disorder which in itself may only be viewed as an obnoxious disturbance in human society; however it must be considered a potential indicator of significant medical problems such as: hypertension, obstructive sleep apnea, cerebrovascular infarction and ischemic heart disease. purpose: the purpose of this study was to evaluate the effectiven...

This case describes some of the commonly overlooked device-related issues in patients who have reportedly failed to respond to cardiac resynchronization therapy (CRT). The case demonstrates voltage-dependent right ventricular capture instead of right atrial capture by a subtly malpositioned right atrial lead. CRT therapy failed to improve symptoms of heart failure and the diagnosis of "CRT nonr...

BACKGROUND Humeral fracture after subpectoral tenodesis of the long head of biceps tendon (LHB) is a rare but devastating complication. PURPOSE To determine whether malpositioned (laterally eccentric) tenodesis screw placement has an influence on humerus strength reduction compared with central placement. STUDY DESIGN Controlled laboratory study. METHODS Two groups, each consisting of 10 ...
