USE OF ECHOGENIC COATING FOR ULTRASOUND IMAGING OF MEDICAL DEVICES IN DEEP TISSUE LAYERS.

摘要

The invention relates to the use of an echogenic coating composition on a medical device to be inserted into a body at depths greater than 5 cm, comprising: (i) a polymer matrix and (ii) an amount of ultrasound-reflective microparticles having a diameter that is at least 10 and at most 250 µm in size, with a defined relationship between the particle size, expressed as D 50, and the surface density. The invention further relates to a method for ultrasound detection of a medical device at a scan depth greater than 5 cm, by providing the medical device with the echogenic coating composition and to an echogenic assembly comprising the medical device and a convex probe.
