Abstract

Appts., comprising long and short elastic fibres (3,4) connected at one end by cylindrical plug (n/s), has the means of progressively and successively regrouping the threads via adjacent coaxial conical surfaces (10,11,12) with increasing angles of conicity (13,14,15) by pressure on the plug. The filter is composed of fibres (3,4) of different lengths, the longer fibres (4) being twice the length of the shorter fibres (3). Each fibre is curved towards the exterior and the ends of the longer fibres (4) are curved towards the interior. USE/ADVANTAGE - Introduction of blood filter to human or animal circulatory systems. Stable and precise positioning in vein. Low cost. Low number of components of appts. reduces manipulation by surgeon. Sterility maintained.
