1. A prosthesis for trapping undesired particles in a body lumen comprising:
- a generally tubular body having a contracted state and an enlarged state;
said generally tubular body being comprised of a plurality of microfilaments that interconnect to create a pore size no greater than about 500 microns substantially along the length of said generally tubular body;
said generally tubular body being self expandable from said contracted state to said enlarged state; and
, said generally tubular body being sufficiently flexible such that said tubular body conforms to a contour of an inner surface of said body lumen.

Abstract
The present invention includes a prosthesis device composed of a plurality of filaments engaged together to self expand against the inner surface of a vessel. In this respect a pocket is created between the prosthesis and the vessel walls which prevent plaque and other debris from escaping downstream to potentially cause complications.

34. A prosthesis for trapping undesired particles on a body organ comprising:
-
a body having an enlarged state and a contracted state;
said body being comprised of a plurality of microfilaments that interconnect to create a pore size no greater than about 500 microns substantially along said body;
said body being self compressible from said enlarged state to said contracted state; and
,said body being sufficiently flexible such that said body conforms to a contour of an external surface of said body organ. - View Dependent Claims (35, 36, 37)

38. A method of treating a body lumen comprising:
-
providing a self expanding tubular body comprised of microfilaments and having a pore size no greater than about 500 microns;
identifying a region in said body lumen having a probability of generating particle debris;
delivering said tubular body to said region;
expanding a distal end of said tubular body in said body lumen at a location distal to said region;
expanding a remaining portion of said tubular body in said body lumen such that said tubular body substantially conforms to the contour of said body lumen, including the contour of said region. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)
