These days angioplasty, is an endovascular procedure to widen narrowed or obstructed arteries or veins, is almost considered a routine procedure, yet the technology behind it is exacting and subject to rigorous quality and performance control. In this procedure a n empty, collapsed balloon, known as a balloon catheter, is passed over a wire into the narrowed locations and then inflated to a fixed size. The balloon forces expansion of the narrowing within the artery or vein and the surrounding muscular wall, opening up the blood vessel for improved flow, and the balloon is then deflated and withdrawn. A stent may, or may not, be inserted at the time of ballooning to ensure the vessel remains open. Not only are the stents themselves, and the wire used in their construction, tested for tensile strength, compressive strength and stiffness properties, so too are the balloon catheters used to deliver the stent into the body. In recent times, more attention is being paid to
Tinius Olsen engineers are continuously working to improve
the effectiveness of gripping technology to make testing quicker, easier and
more comprehensive. One of their recent
developements are our wedge grip adaptors. These adaptors work with our model
HW14 100kN wedge grips & help operators
test smaller samples without the effort of removing these heavy high force
grips. This cost effective solution allows smaller capacity grips to be
fitted to the testing machine for lower force tensile tests & makes the work easier.
