Abstract
Disclosed are embodiments of devices and methods for providing enhanced echogenicity to medical devices. At least two adjacent echogenic features with an intervening section positioned between the echogenic features are formed as a helical groove in a medical device surface. Each of the echogenic features has a depression that spans between first and second transition lips. In one form, each depression includes a steep portion adjacent a shallow portion wherein the steep portion has a first radius and the shallow portion has a second radius that is larger than the first radius such that the radii capture different wavelengths of ultrasound. The intervening section has a planar surface in which the first and second transition lips do not extend above. In one form, each of the at least two echogenic features has a length that is within 0.1 mm of a length of the intervening section.
