Capturing device to be introduced into a tubular biological conduit of the human or animal body, includes a support sheath (1) having a first axial cavity (2), a pusher (3) capable of sliding in the said axial cavity, a first control permitting a relative displacement between the pusher and the support sheath, and flexible grippers including fastening elements (7) which are disposed peripherally on the pusher. The fastening elements extend forwards, inside the support sheath, and spread apart radially from one another outside the support sheath. The fastening elements (7) are each provided at their distal end with a hook capable of entering into engagement with an inner surface of a tubular article to be captured in the conduit and of compressing it radially by traction. |
