At least one of the three wires 14 can be moved longitudinally with respect to the sheath 12. The at least three wires 14 have distal portions 16 which all together form a means 18 to allow engaging with and removal of the object from the patient. The sheath 12 has an interior 26 with a predetermined cross-sectional area. The at least three wires 14 can substantially fill the cross-sectional area of the interior 26 of the sheath 12.
