Powering future generations of implanted medical devices will require cumbersome transcutaneous energy transfer or harvesting energy from the human body. No functional solution that harvests power from the body is currently available, despite attempts to use the Seebeck thermoelectric effect, vibrations or body movements. Glucose fuel cells appear more(More)
BACKGROUND Tissue kallikrein (tK) and vascular endothelial growth factor (VEGF) are potent angiogenic agents. Upregulation of tK or VEGF was documented in animal models of acute ischemia, yet it remains unknown whether these endothelial cell mitogens are overexpressed in chronic peripheral vascular insufficiency. METHODS AND RESULTS Circulating tK and(More)
The design of the standard CMOS IC core of a commercial wireless burglar alarm system is presented as an example of a very low-power analog VLSI design for battery-operated systems. The main constraint is battery life, which must be at least five years (with standard camera-battery). The chip is composed of a digital (decision) part and an analog interface(More)
OBJECTIVE The objective of this study is to explore the feasibility and efficacy of a new technique for sutureless vascular anastomosis, using glued prosthesis, as a sole anastomosis fixation method in rabbits. METHODS Ten rabbits were randomly selected to conduct the experiment. Five rabbits underwent direct anastomosis of infrarenal abdominal aorta,(More)
BACKGROUND In recent years, several methods and new techniques have been studied and proposed for establishment of sutureless vascular anastomoses, streaming use of sutureless vascular surgery in the future. PRESENTATION OF THE HYPOTHESIS The new vascular connector (NVC) is a hypothetical design of a vascular device, proposed for creation and maintenance(More)
