Vessel connector and kit having an applicator for surgery

摘要

The invention relates to a vessel connector (10) for surgically connecting two vessels and/or prosthetics to each other, comprising a sleeve-shaped body (1), the walls of which are designed to be elastic, such that the force acting on the ligature or suture is limited to the extent that no pressure points or necroses occur in the vessel. It is made of two substantially rigid outer rings (2), delimiting the sleeve-shaped body, and webs (3) present between the rings, wherein at least regions of individual webs have a shape (4) deviating from a straight line over longer distances, and it has at least one ring-shaped region (5) of higher elasticity between the rigid rings. The connector provides a blood-tight connection of at least two natural or artificial vessels, including prosthetic connections, a prosthesis to a natural vessel, or two prostheses to each other. The vessel connection is possible much faster, more easily, and more securely with the novel mechanical connector than using conventional surgical circumferential sutures.

主权项

1. A vessel connector for surgically connecting vessels or vascular prostheses by ligature, comprising
a sleeve-shaped body having
two spaced apart rigid outer rings being fixed in shape, anda plurality of webs connected to said two spaced apart rigid outer rings and which extend longitudinally between said two spaced apart rigid rings, said plurality of webs having outer sections adjoining each of the two spaced apart rigid outer rings and at least one annular area between said outer sections, wherein said sleeve-shaped body has a center axis which passes through said two spaced apart rigid outer rings, and wherein said at least one annular area is configured to yield elastically in a radial direction towards said center axis when pressure is applied, and wherein the at least one annular area is of greater elasticity than the outer sections and the outer sections are of greater elasticity than the two spaced apart rigid outer rings and wherein the at least one annular area is configured to have a smaller diameter than the outer sections and the outer sections are configured to have a smaller diameter than the two spaced apart rigid outer rings when pressure is applied to the at least one annular area.
