Abstract
The aim of this research program was to develop vessel connectors to replace the difficult microsurgical suture, which could be implanted quickly, safely and without any special training. Three types of connectors were developed specially for the anatomical features of the head and neck region: miniconnectors, stick connections with vascular prosthesis, and interposition connectors. The development of the model, the biomechanical tests on the in-vitro system comprising a free, muscular, porcine latissimus-dorsi flap, and the in-vivo tests involving implantation of the connectors in vessels of rats, rabbits, dogs and pigs are outlined. The results are compared with those obtained with conventional microsurgical interrupted sutures.--The indications for these three different types of connector are determined by the diameter and quality of the vessels (vein, artery).
