Abstract
An ultrasonic echogenic device (100) includes a base layer (1), an echogenic layer (2) covering the base layer (1) and adhered to the base layer (1) at least by a separate lower adhesive (4), an outer layer (3) covering the echogenic layer (2) and adhered to the echogenic layer (2) at least by a separate upper adhesive (5), wherein the ultrasonic echogenic device (100) is configured such that a rough interface is provided at a position where the echogenic material of the echogenic layer (2) contacts at least the upper surface of the upper adhesive (4), and the outer surface of the outer layer (3) at least partially follows an undulation of the rough interface. An ultrasonic echogenic device (100) with a simple structure and easily formed is obtained.
