Abstract
Medical devices, wherein at least one part of the outer surface of the container is grooved, preferably with a curved groove are disclosed. The grooved outer surface is preferably substantially free from angularities. Such grooves enhance the echogenicity of the device using medical ultrasound at a greater range of angles to the ultrasound probe, thus enhancing the ultrasound visibility of the device.
