Abstract
The method for manufacturing a blood filter adapted to be disposed in a blood vessel comprises, in the invention, the steps of a) providing a thin wall comprising a biocompatible material, b) producing in said thin wall a series of essentially parallel elongated sections, for defining the elongated legs, and having the elongated legs joined to each other, at a first end of the elongated sections, wherein step b) comprises the steps of producing adjacent essentially parallel strips comprising a first strip and a second strip separated by a slot, the strips extending essentially parallel the axis and each slot being interrupted at a distance from a second end of the elongated sections, so that the first and the second strips are connected to each other at said second end, by a continuous zone of said thin wall, and having the first strip of the elongated sections joined to each other, at said first end thereof.
