Title:
身体管腔において適合性の構造物を配置するための方法および装置
Document Type and Number:
Japanese Patent JP2008505703
Kind Code:
A
Abstract:
Occluding structures may be created within a body lumen by advancing a length of material distally through the body lumen. By drawing a distal location on the advanced length of material in a proximal direction, the material may be compacted into a structure which at least partially occludes the lumen. The occluding structure may be used for a variety of purposes, including removing obstructions from the body lumen, such as kidney stones from the ureter; providing hemostasis in a blood vessel; providing occlusion of a fallopian tube; temporary constraint of stone fragments in the urinary tract; capture or restraint of clot in blood vessels; and the like. Apparatus for performing the method may comprise a length of material attached at its distal end to tubular guide or other advancement member. Tensioning members may also be provided for collapsing and compacting the length of material within the body lumen.
