Abstract: A device for anastomosis of a tubular structure comprises first and second hollow members having a rigid part and an elastic part, and a connection member for interlocking the first and second members. The elastic parts are essentially circular rings, and are made of a polymeric, a biocompatible and/or biodegradable material. The rigid parts have an outer surface that is partly semi-circular in cross section, wherein the diameter at a non-connecting end is larger than or equal to the diameter at a connecting end, which ends in an edge. The first and second members are connected to each other so that a distance is formed between the elastic parts. A cavity is formed between the rigid parts and the connection member and the tubular structure, when arranged in the device.

A tool (400) for use in connection with an anvil (300), according to above, is also provided, and a kit of parts comprising the two. The tool (400) comprises a receiving member (401) for receiving the connecting rod (302) of the anvil (300), and a seat (405) for a second member (20) of the anastomotic device (100), said seat (405) being arranged circumferentially of said receiving member (401), and said receiving member (401) being displaceable in relation to said seat (405).

Abstract: A device (100) for arrangement on the side wall of an intestine is provided. The device (100) comprises a first member (10) and a second member (20) of a generally hollow open configuration. The first member (10) comprises an elastic part (11), with a first and a second axial end, and a rigid support part (12), arranged at the first axial end of the elastic part (11). The second member (20) comprises a first and a second axial end, said first end of the second member (20) matching the shape of the second axial end of the elastic part (11), such that an intestine wall may be uniformly distributed between the second axial end of the elastic part (11) and the second member (20). The device (100) also comprises a connection member (30) for connecting the rigid support part (12) and the second member (20) to each other. A method for arranging said device at the side wall of a tubular structure, and a connector (200) for connecting two devices (100) is also provided.

Abstract: A mounting tool for mounting a flexible ring-shaped part of an anastomotic device on a rigid part of an anstomotic device is provided. The tool comprises a receiving portion (104) in a distal end of the mounting tool for receiving the flexible part thereat and a handle portion (103) proximally of said receiving portion (104). Said receiving portion (104) comprises an elongated tubular sheet element (101), and a tubular displacement element (201), arranged within the sheet element (101) to be longitudinally displaceable in relation to the sheet element (101), such that a shelf (401) is obtained circumferentially of the tubular displacement element (106) and distally of the sheet element (101). The shelf (401) is configured to receive the flexible part. A mounting tool for receiving a flexible ring-shaped part of an anastomotic device on a rigid part of an anstomotic device is also provided.

Abstract: A mounting tool (20) and method for mounting an anastomotic device (10, 200) to an end (220, 221) of a tubular structure (90) comprises a receiving portion for receiving a rigid part (11, 13) of said device (10, 200) and a conical portion with a large end facing said rigid part (11, 13) having a diameter larger than or equal to the rigid part (11, 13) and a small end. The conical portion comprises a releasable portion and is insertable into the elastic part (12) arranged inside the tubular structure (90) for expanding the diameter thereof and for passing the elastic part (12) beyond the large end and onto a rigid part (11, 13) arrangeable at the receiving portion.

Abstract: Devices and methods for anastomosis are provided. The devices can include a first and a second member of a generally hollow open configuration. The first and second members may each include a rigid part and an elastic part arranged circumferentially of the rigid part. The devices may also include a connection member for interlocking the first and second members such that anastomosis is obtained at a contact area in-between the elastic parts. The methods can include arranging an elastic part inside a tubular structure at a first end of the tubular structure, folding an edge of the first end over the elastic part, and mounting the elastic part on a rigid part, forming a first member. This may be repeated at a second end of the tubular structure, forming a second member, and the first and second members may be locked to each other by a connection member.
