Abstract: According to some embodiments there is provided an anastomosis device configured to reduce leakage, comprising: a first set of rings sized to be positioned at a first tissue wall; a second set of rings sized to be positioned at a second tissue wall adjacent the first tissue wall; and an element configured to draw the ring sets towards each other; wherein each set of rings comprises an inner ring, an outer ring, and a coupling for aligning the inner and outer rings with respect to each other; wherein the inner ring applies a first pressure onto the tissue wall which is sufficient to gradually form a passage between the first and second tissue walls; and the outer ring applies a second pressure onto the tissue wall, the second pressure applied radially outwardly relative to the first pressure, the second pressure sufficient to reduce leakage in a vicinity of the passage.
