Are integrated by, for example, sewing or bonding. As particularly preferred means of integration, a coarse-pitch sewn stitch that can easily separate the two after surgery can be exemplified, and the thread ends thereof are extended to an appropriate length in order to facilitate the separation operation. It is desirable to put out. Examples of the sewing thread include a sewing thread for sewing clothing, a medical suture, and the like.
It is composed of any of non-biodegradable and absorbable materials such as polyester, vinylon, cotton and silk and the above-mentioned biodegradable and absorbable materials. In consideration of the possibility that the suture is caught and remains in the body, it is preferable that the suture be made of the same material as the biodegradable and absorbable material of the present invention. Further, it is important to achieve the above-mentioned purpose that the inner diameter of the tube formed by the integration is equal to or smaller than the outer diameter of the suturing device to be applied. Therefore, the size, shape, It is desired that the sewing means and the like for integration match this purpose.

The cloth-shaped body cut to the size is joined by an arbitrary method such as suturing or bonding. For example, it is advantageous in terms of workability after a suturing operation to be described later that rough sewn or temporary bonding is used. Therefore, it is particularly preferable. However, a knitted fabric knitted in a high-density tubular shape may be used as a suture prosthetic material so as to be suitable for the use.
