Apparatus for entrapping and extracting objects from body cavities

A retrieval apparatus for entrapping and retaining an object located in a body for its extraction therefrom, the apparatus comprising a retrieval snare being changeable between its contracted state and a deployed state and formed by a plurality of filaments defining proximal and distal sections interconnected to each other, the proximal section having a longitudinal axis;

• wherein the filaments extend from a proximal end of the proximal section towards the distal section, and then return to the proximal end to form a plurality of loops,
• wherein the loops are interlaced with each other only within the proximal section, while being free within the distal section in the deployed state,
• wherein the filaments forming sides of at least a part of the filament loops are bent at least one time to define a sequence of straight wire segments angled with respect to each other within the proximal and distal sections, when viewed from a plane substantially parallel to the longitudinal axis, and arcuate into arcs at a distal end of the distal section.
