ABSTRACT:
A surgical device for removing a foreign object from a body is described. The device includes a retrieval basket for entrapping and retaining the object located in the body, a basket control assembly comprising a tubular sheath adapted to penetrate into the body for reaching the object, and a manipulator for manipulating the basket for extraction the object from the body. The basket comprises a structure having a proximal end and a distal end. The structure is formed by a plurality of filaments fabricated from a single or several wires. The filaments extend from the proximal end towards the distal end. At least a part of the filaments are configured in the form of loops. At least a part of the loops are interlaced so as to define a net at the distal end, and thereby impart structural rigidity and dilatation ability to the basket when opened.
