Abstract
The present invention provides a novel vascular anastomosis device capable of anastomosing readily the side (lateral portion) of a vessel to the side of another vessel. By employing the vascular anastomotic device of the present invention, it is possible to anastomose two vessels in the side to-side type which is generally very difficult in the art associated with anastomosis, by simple procedure without using a suture, whereby the operative time decreases remarkably. Furthermore, since the operative site needs not to be opened fully, a patient's pain can be released.
Claims7
A vascular anastomotic device for side-to-side anastomosis comprising,
- a pair of assembly members being able to join and disjoin along its axial plane, the joined assembly members generally being of a tubular shape of which the bottom is closed, wherein each assembly member comprises upper and lower units;
- a protruding member installed at the upper portion of each assembly member, the protruding member having a plurality of hooking means which are positioned downwardly along the circumferential surface of the bottom of the protruding member;
- a connecting member installed inside each assembly member between the upper and lower units, the connecting member connecting the upper and lower units when these units are separated by the pulling force applied to the device;
- and
- semicircular openings formed at both sides of each assembly member, the semicircular openings of an assembly member making two circular openings together with the semicircular openings of the corresponding assembly member when a pair of assembly members join, wherein the two circular openings provide a passage penetrating the assembly members laterally.
