Abstract
An echogenically enhanced medical device and method for manufacture are disclosed. A mask is applied to the surface of the medical device, and portions of bare metal are exposed through the mask. The masked device is subjected to a process which removes material from the exposed portions. The resulting depressions enhance echogenicity of the device under ultrasound. In a preferred embodiment the depressions comprise alternating rows of squares and diamonds disposed around the circumference of the device.
