Abstract:
A device for extracting an object featuring a longitudinal inner lumen from its attachment in a body, wherein said extracting device comprises:a tube having a longitudinal axis, a distal end, and a proximal end, said distal end having a contact surface;a cable extending through said tube, said cable having a distal end which projects from said distal end of said tube, said distal end having an anchoring part with a stop surface facing said contact surface of said tube, said stop surface and said contact surface defining an acute angle from about 15 degrees to about 75 degrees, one of said stop surface and said contact surface disposed at an acute angle to said longitudinal axis, wherein said anchoring part, together with said tube, can be inserted into the inner lumen of the object to be extracted; andan actuation device for activating relative motion between said tube and said cable such that, when said stop surface of said anchoring part is drawn towards said contact surface of said tube distal end, said anchoring part tilts with respect to the longitudinal axis of said tube as said contact surface and said stop surface are drawn together and causing said anchoring part to engage said inner lumen, thereby anchoring said anchoring part in said inner lumen of the object to be extracted.
