Filter media and methods of manufacture
First Claim
1. A method of constructing a filter for use in connection with an embolic protection device, the method comprising:
- forming a first section of a filter material by masking a larger section of a filter material according to a predetermined pattern and removing the excess filter material outside of the predetermined pattern with at least one of a laser beam and a solvent, the first section having a first edge and a second edge;
contacting at least a portion of the first edge with at least a portion of the second edge;
bonding together the at least a portion of the first edge with at least a portion of the second edge, such that the first section is formed into a sack-like shape.

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.
