Device for deployment into an interior body using expandable bodies attached to first and second catheter tubes

摘要

A device for deployment into an interior body region comprising a first catheter tube having a distal end, the being formed from a first material, a second catheter tube extending beyond the distal end, the second catheter tube being formed from a second material which is more compliant than the first material, and a structure carried by the first and second catheter tubes comprising a body adapted to assume a collapsed geometry for deployment into the interior body region and an expanded geometry for use within the interior body region, the body including a first end region secured to the first catheter tube and second end region secured to the second catheter tube, the body being formed from a material more compliant than the first material.
