aspect according to the invention a basket 10 of a device for retrieving biological or foreign material from a body has a plurality of legs for example as shown in fig1 b four legs 11 a 11 b 11 c 11 d an end on view of the basket 10 in fig1 d illustrates a substantially tipless or atraumatic distal end 100 a small insubstantial protrusion or depression may remain at the distal tip as a result of the manufacturing process such features on the basket tip do not poke tear pierce perforate bruise or otherwise inflict injury or cause trauma to the tissue and may enhance basket performance in one embodiment for example the legs 11 a 11 b 11 c 11 d and the atraumatic basket 10 can be cut etched stamped or otherwise removed as a single shape or profile from a substantially flat piece of material 101 as illustrated in fig1 a in another embodiment referring to fig1 e 1 g and 6 b just the distal end portion 5 of the basket 10 is removed as a single shape or profile from a single piece of substantially flat material alternatively the basket 10 or distal end portion 5 can be injection molded into the desired shape by for example plastic injection molding metal injection molding mim or by compression of metal powders as illustrated in fig1 a and fig1 c the starting profile.
