sutento - transplantation one synthetic instrument and production method of tube condition

摘要

(57) Abstract The internal professional thesis instrument for the sutento - transplantation one synthetic tube cavity has the PTFE liner which distribution facilities is done for long diameter direction alongside PTFE sutentokaba and the inside surface of sutento which distribution facilities are done alongside the outer part surface of enlarging reduction possible tube condition sutento and sutento. As for one side inside sutentokaba and sutentoraina, it is formed from the extrusion type tube which does not have connection, another side inside the aforementioned cover and the aforementioned liner is formed from long ePTFE seat. The long seat it has the longitudinal direction end of opposition side, connects mutually and forms the tube condition structure. As for sutento, way the enlarging reduction of diameter direction is possible, between the surface inside and outside opposite side it has the plural opening areas which extend, the liner and the cover it is connected mutually via the opening area of sutento. The liner and the cover with the adhesive may be adhered by gluing via the aforementioned area, the cover and the liner may be covered mutually via the opening area of sutento.
