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 a 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 surfaces, 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.
