Avago Medical specializes in the manufacturing of tube occluding clamps for dialysis and blood collection centers. We combine science and technology to design and create safe and reliable clamps to occlude medical grade tubing 1 mm to 8 mm OD without any damage. Each bag of clamps is accompanied with instructions for use (IFU's) in four different languages. The founder worked for major medical device manufacturers and learned the design and manufacturing of invasive and non-invasive medical devices. Our clamps are made of Nylon. They are tested to be safe, reliable, lightweight and inexpensive compared to clamps made of metal.
