Compression anastomosis system, and use thereof

A compression anastomosis system comprising matching first and second compression ring devices (1, 40, 50, 60, 70, 80, 90), each compression ring device configured for adjustment from an elongated delivery configuration suitable for passing through a lumen of a minimally invasive surgical instrument to a deployed radially expanded configuration,

• wherein the compression rings comprise coupling elements (20, 41, 56, 57) for coupling the rings together in a face-to-face compression anastomosis configuration, and
• wherein each compression ring device comprising tissue anchors (12, 58) configured to anchor the ring to a wall of a body lumen when the ring is deployed in the body lumen,
• in which the or each anastomosis ring in the deployed radially expanded configuration comprises:
• an annular tube that is biased into a ring shape and resiliently deformable;
• and
• a plurality of ring segments disposed within the annular tube.

A compression anastomosis system comprising matching first and second compression ring devices (1, 40, 50, 60, 70, 80, 90),

• wherein each anastomosis ring is configured to self-deploy from an elongated delivery configuration suitable for delivery in a minimally invasive surgical instrument to a radially expanded configuration,
• wherein each anastomosis ring in the radially expanded configuration comprises:
• an annular tube that is biased into a ring shape and resiliently deformable;
• and
• a plurality of unconnected ring segments disposed within the annular tube.
