Abstract
We prepared an external shunt cannula with collagen-immobilized polyethylene sponge cuff for the purpose of attaining adhesiveness to the skin tissue through the cuff. Both ends of silicone cannulas with and without the cuff were implanted into the rabbit dorsal subcutaneous tissue. The skin tissue grew over and strongly adhered to the cuff of the silicone cannula. Attachment of the cuff was quite effective on adhesiveness to the skin and prevention of tunnel infections. This cuff can be used for peritoneal catheters for CAPD.
