Anastomosis assembly

An anastomosis assembly for joining one stump of a cut tubular organ to another comprising:

• a device having a body with a longitudinal axis and two opposite axial projections, each of which being configured for insertion into a stump to be joined to another stump and to permit the stump walls to be pulled over a stump-engaging portion of the external surface of the axial projections;
• a plurality of curved, open needle-guiding channels, each of which extending in a general axial direction between a first end and a second end defined in the stump-engaging portion of one of the axial projections and configured for receiving a suturing needle, having a pointed front and a rear linked to a suturing thread, wherein each open needle-guiding channel is configured to guide the pointed front of the suturing needle to pierce through stump walls;
• and each of the two opposite axial projections comprises a retaining element in the form of an elastic element, fitted directly over the open needle-guiding channels within a circumferential groove defined on the surface of the axial projection directly over the open needle-guiding channels, the retaining element is configured for retaining the suturing needles within the open needle-channels before and during the needles movement in the open needle-guiding channels to pierce through stump walls, and the retaining element is configured to be cut or broken to permit freeing of the suturing threads from the device upon the removal of the retaining element.
