Wireless vital signs from a life-supporting medical device exposed to electromagnetic disturbance.
To evaluate the level of agreement of simulated wired and Wi-Fi vital signs output from an intra-aortic balloon pump during exposure to electromagnetic interference from frequency overlapping ZigBee sensors. ⋯ Level of agreement in wired and wireless (Wi-Fi) arterial blood pressure and electrocardiogram during single or multiple sensor interference was high. No clinically relevant degradation of Wi-Fi transmission of aortic blood pressure or ECG signals was observed.

Percutaneous use of ePTFE/FEP-covered metallic stent for palliation of malignant biliary obstruction.
Placement of self-expanding metallic stents has been a standard palliative treatment for patients with inoperable biliary malignancy, aiming at improving quality of life via a minimally invasive procedure. This study aimed to evaluate the efficacy of percutaneous placement of expanded polytetrafluoroethylene/fluorinated ethylene propylene-covered metallic stents for palliation of inoperable biliary malignancy. ⋯ Percutaneous placement of expanded polytetrafluoroethylene/fluorinated ethylene propylene-covered metallic stents offered an effective palliative therapy for patients with inoperable biliary malignancy.
