Filters and method of manufacturing filters are disclosed herein. The filter has a substantially sack-like shape having a closed distal end and an open proximal end. The filter can be constructed from thin film. The filter material can be an organic or inorganic polymer. In one embodiment, the filter material is a polyurethane film having a thickness of less than 25~m. The filter can be constructed from one or more sections of filter material. In the two-section embodiment, the outer edges of the first and second sections are overlapped and bonded using solvent, heat or other bonding process. In the single-section embodiment, the outer edges of the first section are overlapped and bonded using bonding agents, such as solvent or adhesive, heat or other bonding process. Filters of the present invention have a reduced amount of hysteresis so as to reform to its original shape when deployed.

Cette invention porte sur des filtres et un procédé pour les fabriquer. Un tel filtre se présente sous forme d'un sac à fond fermé et extrémité proximale ouverte. Il peut être en film mince. Son matériau est un polymère indifféremment organique ou inorganique. Dans un mode de réalisation, il s'agit de film de polyuréthane de moins de 25 ?m. Il peut être fait d'une ou de plusieurs pièces de matériau filtrant. Pour le modèle deux-pièces, les bords extérieurs des deux pièces sont collés en chevauchement par un solvant, par thermosoudage ou autre procédé de liaison. Pour le modèle une-pièce, les bords extérieurs sont mis en chevauchement et réunis par des agents collants (solvant ou colle), ou par thermosoudage ou autre procédé de liaison. Les filtres de l'invention présentent une moindre hystérésis concernant le retour à la forme initiale une fois déployé.
