Abstract
A medical retrieval device, and related method, uses a basket formed by one or more legs to retrieve material such as calculi. At least one of the legs has at least an inner and an outer surface. The outer surface is an atraumatic surface such as a curved surface. The atraumatic surface can include one or more radii. The inner surface can be flat such that the leg has a D-shaped cross section. Other shapes are possible for the inner surface including a pointed shape that enhances the basket'"'"'s stone crushing or breaking ability. The inner surface, whatever its shape, can have a rough surface (e.g., serrated, etched, toothed, etc.) for further enhancing the basket'"'"'s ability to capture stones and other calculi.
