PURPOSE: To provide a better weaving pattern for a cloth used for a transplantation tube by forming fixing weaving elements at a plurality of positions over a whole cloth matrix, according to a specific weaving way. CONSTITUTION: The left end of a transplantation tube 10 is cut at a slantwise angle and formed out of woven fabric 12 in this case. Ribs 145 are provided on the tube 10 along a lengthwise direction and formed by permanently shrinking the tube 10 after the weaving thereof into a cylindrical form. Prior to fitting the tube 10 to a patient's blood vessel along a suturing line 22, the tube end is cut at a slantwise angle and an opening corresponding to the cut part is formed on the blood vessel, thereby allowing the tube 10 to be properly fitted at the time of transplantation. Also, woven fabric 24 is wound around the external surface of a take-up roll 25 rotating in a counterclockwise direction. Furthermore, the woven fabric 24 is manufactured by use of transverse fill threads woven via warps indicated as 28a and 28b. For forming each type of the patterns of a plain weave, a twilled weave and a leno elastic weave, colored threads 29a and 29b are selectively moved. |
