Abstract
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 les than 25 μm. 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.
