Endoluminal filter having enhanced echogenic properties

A system for positioning a filter within the vasculature, the system comprising:

• 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 guidewire having a proximal end, a distal end, and a first pressure sensor located near the distal end of the guidewire;
• a sheath having a proximal end, a distal end and a lumen, the lumen configured to receive the guide wire;
• the filter attached to a distal portion of the sheath;
• an intravascular ultrasound transducer disposed at the distal end of the sheath;
• a user interface configured to receive input from an operator regarding a surgical procedure including an insertion site and a destination site for positioning the filter according to the surgical procedure;
• a display;
• a processor programmed to:
• receive input from the user interface regarding the surgical procedure;
• determine anatomical landmarks between the insertion site and the destination site;
• receive an intravascular ultrasound signal from the intravascular ultrasound transducer;
• process the intravascular ultrasound signal into an image;
• and
• send the image to the display.
