Abstract
A set of cannula components, the cannula being of a kind which has an end region of sufficient dimensions as to be located, in use, in an aperture of body tissue, a thread being woven around the aperture so that, when the thread is drawn, the fluid is primarily channelled through the cannula, wherein the set comprises at least one clamp configured to tightly fasten onto the outside of the wall of the cannula whilst in a region being sufficiently spiced from the cannla wall to be able to accommodate the passage of a flexible wall tube through which a thread may be drawn; and at least a second clamp configured to squash said flexible wall tube in order to substantially immobilise a thread located inside the tube in order to keep the thread in its desired position.
