It repeats the material or the fluid in the organism organizational region of goal and it plants over the long term in order delivery to do intermittently the possible guide tube

摘要

Biological and chemical, it is the remedy delivery system which delivery does the medicine intermittently in organism organization. Plants in order the possible guide tube and, 1st stop to operate mechanically mutually, possesses the 2nd stop which is provided this system, is provided in the proximal edge of the guide cannula and the aforementioned guide cannula which possess the proximal edge and the distal (2036) edge at the same time, in order to plant in the long term in the patient, is provided the 1st stop which is provided in the distal (2036) edge vicinity of the access port, and the aforementioned guide cannula, over the long term when it possesses, passes by the aforementioned access port and the insertion possible delivery cannula and, has possessed in the aforementioned guide cannula. The delivery cannula operates is constituted mechanically 1st stop and mutually, at the same time, the delivery cannula exceeding specified distance from the distal (2036) edge of the guide cannula, in order to prevent the fact that it extends. The organism organizational - stab tip/chip is provided in the distal (2036) edge of the delivery cannula which penetrates target region adjacent growth organism organization. When the delivery cannula is not in the midst of using, sutairetsuto is used in order to possess the lumen of guide cannula.
