PURPOSE:To provide a device for halting the medical equipment in organism, wherein a device surface exibits an elevated lubricating property to facilitate the insertion and the removal of equipment in organism, while a device surface becomes relatively frictional for the convenience of fixing and halting of equipment in organism. CONSTITUTION:Surface of a baloon 5 located at the inserting portion 4 is devised to have the temperature sensitive lubricating layer 6. The layer exibits hydrophilic and lubricity at a temperature below a critical value, while it shows hydrophobic and nonlubricity at above the critical temperature. |
