Abstract: A composition for forming a temporary intestinal occlusion in a mammal is flowable and solidifiable to form a solid plug at a predetermined site in the intestine, the structure of the plug being changeable to allow for a subsequent, at least partial removal of the occlusion. The composition is or comprises a flowable solution, suspension, or dispersion in a solvent or mixed solvent, and comprises the following: a) a suspension of a solid in water or an aqueous mixed solvent, the suspension having a water content which exceeds the flow limit of the suspension by a specific amount; b) a dehydrating agent in an amount which is sufficient to bind the specific amount of water, so that, as a consequence of dehydration, the flow limit of the suspension is exceeded; and c) a means for passivating the dehydrating agent.

Abstract: The present invention relates to a method for forming a temporary obstruction of the intestine of a mammal, using a solidifiable composition, said composition being flowable and solidifiable to form a solid plug at a desired site within the intestine, the structure of said plug being changeable in order to allow for the subsequent, at least partial removal of the obstruction.

Abstract: An instrument for the surgical closure of a trocar puncture through a posterior fascia introduced during a laparoscopic operation comprises a tube (1) with a forward insertion end (2) and a rearward end (3), in whose shell wall (5) opposing window openings (7) are formed, in which terminates at its margins remote from the insertion end (2) of the tube (1) at least one bore (8) extending in the shell wall (5) in the longitudinal direction of the tube (1), hollow needles (10), each disposed in one of the bores (8) and displaceable between a retracted position, in which they clear the particular window opening (7), and an end position, in which they cross the window opening (7), and each having an inner channel (17), wherein each of the inner channels (17) of the hollow needles (10) forms a section of a guide channel for guiding through a suture thread (36), and this guide channel further includes at least one curved connecting section (18), which connects the front ends of the inner channels (17) of two holl
