Beschreibung
Zusammenfassung:	An echogenic coating composition on a medical device to be inserted into a body at depths greater than 5 cm includes: (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 D50, and the surface density. A method for ultrasound detection of a medical device at a scan depth greater than 5 cm includes: providing the medical device with the echogenic coating composition and to an echogenic assembly including the medical device and a convex probe.
