A DEVICE, A SYSTEM AND A METHOD OF MOVING IN A TUBULAR CHANNEL

摘要

The invention relates to a device (100) for moving in a tubular channel comprising a first part (302) and a second part (306). The first part comprises a reservoir (A) and a piston (304) and is connected to the second part (306) via a hollow tubular member (305) attached to the piston (304) in such a way that translation movement of the piston performs a translation movement of the hollow tubular member (305) and the second part (306) attached thereto. The device (100) additionally comprises two gripping means (101) fluidly connected via a pump (400); wherein a first (G1) of the two gripping means comprises a fluid; the pump is adapted to inflate a second (G2) of the gripping means by pumping the fluid from the first of the two gripping means to the second of the two gripping means; and the gripping means comprises a flexible member (201) contained in a woven member (202), wherein the flexible member provides fluid-tightness and the woven member provides the shape of the gripping means. The invention also relates to a method of moving a device (100) in a tubular channel and a system therefor.
