A retrieval medical device for entrapping and retaining an object located in a body for its extraction therefrom is described. The device includes a basket-filter constituted by a plurality of filaments extending from the proximal end towards the distal end. The filaments are bound together in the vicinity of the proximal end to form a plurality of main branches. Each main branch includes at least two filaments. The filaments are entangled together in the vicinity of the distal end. Each main branch has a ramification point at which it ramifies into at least two single filaments extending from the ramification point towards the basket distal end of the basket-filter. One of the single filaments extends in the form of a right spiral, whereas another single filament extends in the form of a left spiral. The filaments extending from the ramification points interlace with each other, thereby forming a mesh between the branching point and the basket proximal end having density greater than 5.1 crossover points per inch.
