SCREW ANASTOMOSIS DEVICE Russian patent published in 2008 - IPC A61B17/11 A61B17/64 

FIELD: medicine.

SUBSTANCE: invention refers to anastomosis devices and can be used for anastomosis of either lateral face of one vessel to another vessel, or end of one vessel to lateral face of another vessel, such as, e.g. blood vessels, intestine, ureters or trachea with walls of certain thickness. Screw device comprises screw-shaped coiled spiral spring with non-cutting perforating assembly. Coils of screw-shaped spiral spring are connected by preset minimal distance. Minimal distance between coils corresponds to thickness of vessel walls. Non-cutting perforating assembly is rigid to screw-shaped spiral spring or detachable to screw-shaped spiral spring. As a result device provides possibility of joined either lateral parts of two vessels (side-to-side) or end of one vessel to lateral part of another vessel (end-to-side) without suturing.

EFFECT: development of device design, allowing vessels joining without suturing.
