| 摘要 |
The present invention is directed to a device and method for safely removing matter collected by a matter collecting catheter from body organ or internal passage by means of a collecting sheath comprising an elongated tube having at a distal end thereof a deformable container sleeve, a main lumen passing therealong, said lumen being suitable for the passage of the matter collecting catheter through said elongated tube and said deformable container sleeve, and a secondary lumen passing along the walls of said elongated tube and said deformable container sleeve, wherein said secondary lumen terminates in a distal opening near a distal opening of said deformable container sleeve such that a distal end portion of a wire passed through said secondary lumen may be adapted to close said distal opening of said deformable container sleeve by proximal retraction of said wire. |
