ABSTRACT
Objective To develop an interlocking-style vascular shunt device for the treatment of distal limb ischemia resulting from vascular disconnection and defect.Methods A one-way interlocking buckle was designed with the space between the clamping teeth being 0.5 mm,which prevented the device from moving backwards and fixed the vessel and shunt tube conveniently.The interlocking buckle combined with silicone tube was used to connect the two ends of the defected vessel,which was compared with conventional method by suture ligation and silicone tube by the tests on vessel bursting pressure and tensile biomechanics.Results The vessel repaired with the developed device behaved better than that by the conventional method in the tests on vessel bursting pressure and tensile biomechanics (P<0.05).Conclusion The vascular shunt device can be used for the treatment of distal limb ischemia resulting from vascular disconnection and defect,and thus facilitates the vascular graft in rear hospital after evacuation.
