Abstract:
A method for manufacturing a blood filter adapted to be disposed in a blood vessel, the blood filter having an axis and comprising elongated legs extending around the axis, the method comprising the steps of:a) providing a thin wall comprising a biocompatible material, b) from the thin wall, producing a series of essentially parallel elongated sections, for defining the elongated legs, the elongated sections having a longitudinal first end and a longitudinal second end, c) joining the elongated legs to each other, at the first end of the elongated sections, so that the elongated legs are radially movable between a first position in which the legs are radially expanded and a second position in which the legs are radially restricted, wherein step b) comprises the step of: d) in at least some of said parallel elongated sections, 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 the second end, so that the first and the second strips are connected to each other at the second end, by a continuous zone of said thin wall, and wherein step c) comprises the step of: e) joining the first strip of the elongated sections to each other, at said first end thereof.
