Abstract

There is a continuous need for angioplasty related products to achieve lower profiles than before This means that the devices have the opportunity to reach more distal lesions and have potential uses in neural catheterisation. Lower profiles can be achieved by reducing the wall thickness of the device, and thus, reducing the outer diameter of the tubing. However, this, on its own, can have major consequences on the mechanical properties and performance of the device. One of these consequences is the kinking of tubing. This paper identifies a test method that can accurately reflect the kink properties of any thermoplastic tubing using Dynamic Mechanical Testing Analysis (DMTA).
