Abstract
A medical retrieval device includes a handle, a sheath, and a basket having basket legs and an atraumatic distal tip. The atraumatic tip of the basket is formed, for example, by entwining the ends of the basket legs together at the distal tip of the basket. Baskets with atraumatic tips according to the invention allow the capture of material from difficult to reach areas of the body while reducing the risk of tissue damage.
