An endoluminal filter, comprising a first support member having a first end and a second end; and a second support member attached to the first end of the first support member or the second end of the first support member and forming a crossover with the first support member to form two loops one on either side of the crossover, wherein at least a portion of the first support member, the second support member, the first end, the second end or a region adjacent to the cross over or any portion of one of the above is modified to provide an enhanced echogenic characteristic of the endoluminal filter. A method of positioning a filter within a lumen, comprising advancing a sheath containing a filter through the lumen; deploying a portion of the filter from the sheath into the lumen to engage the lumen wall while maintaining substantially all of a material capture structure of the filter within the sheath; and deploying the material capture structure of the filter from the sheath to a position across the lumen, wherein any of the above steps are performed using an intravascular ultrasound system and the filter is modified to provided at least one echogenic characteristic.
