摘要： A cuff member that enhances the invasion and engraftment of cells from subcutaneous tissue of a living body and robustly adheres to the subcutaneous tissue through the vascularization of capillary vessels, and can consequently isolate a wound from the outside, block exacerbating factors such as bacterial infection during healing, inhibit the downgrowth, and reduce infection problems including tunnel infection. A cuff member 2 includes a flange 3 and a tubular portion 4. The cuff member 2 includes a three-dimensional network open-cell porous structure, which is formed of a thermoplastic resin or a thermosetting resin and has an average pore size of 100 to 1000 μm and an apparent density of 0.01 to 0.5 g/cm3. A pad 5 overlies the flange 3. A tube 6 passes through the pad 5 and the flange 3.
