Method for manufacturing a surgical device for extracting a foreign object
First Claim
1. A method for manufacturing a retrieval basket having a proximal end and a distal end and constituted by a plurality of wire filaments extending from the proximal end towards the distal end, comprising:
- selecting at least one wire;
weaving the basket from the wire, wherein said weaving includes forming portions from wire filaments that are bound together to define a plurality of strands, said plurality of strands ramify at corresponding branching points into loops having various shapes and sizes, at least a part of the loops are overlapped and/or interlaced at spaced points so as to define a net at least in the vicinity of, and spaced from the distal end; and
forming a shape of the retrieval basket, thereby imparting structural rigidity and dilatation abilities to the basket when opened.

Abstract
A method for manufacturing the surgical device for removing a foreign object from a body and a retrieval basket of the device are described. The retrieval basket is adapted for entrapping and retaining the object located in 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, and are bound together to define a plurality of strands. The strands ramify at corresponding branching points into loops having various shapes and sizes. At least a part of the loops are overlapped and/or interlaced so as to define a net, and thereby impart structural rigidity and dilatation ability to the basket when opened. The method of manufacturing the retrieval basket includes selecting at least one wire; weaving the basket from the wire by overlapping and/or interlacing the filaments so that to form a net at least in the vicinity of the distal end; and binding the filaments for forming a shape of the retrieval basket.
