PROBLEM TO BE SOLVED: To provide a catheter attachment system employed for use in a kit-type medical operational implant.;SOLUTION: The attaching system, which is a fixing system for fixing a catheter in an operational implant, comprises a bendable enlargement expanding from the operational implant to the periphery of the catheter attached to the operational implant, wherein the bendable enlargement has a form to regulate a slot inside the enlargement, and a connector having at least one expanding tab is disposed around the catheter to attach to the operational implant. The tubular connector is rotated to allow at least one tab to touch with the slot of the bendable enlargement, so that the connector is rotated from the unfixing position to the fixing position inside the slot to bend releasably at least one part of the slot. The rotation movement fixes the catheter to the operational implant, and can generate a feedback for a surgeon to sense.;COPYRIGHT: (C)2008,JPO&INPIT
