Abstract: A positioning device for a stent includes a positioning member including a handle and an extension secured to the handle wherein the handle and the extension are coaxially connected, and an open end of the extension is provided with a hollow first magnetic member; and a stent inserted into a blood vessel and including a first stent member inserted into an artificial blood vessel, the first stent member being separated into two second stent members inserted into the artificial blood vessel wherein a diameter of the first stent member is greater than that of each second stent member, and a diameter of each second stent member is greater than that of the extension, the stent further comprising at least one second magnetic member on the first stent member proximate an open end thereof, the second magnetic member being configured to attach to the first magnetic member.

Abstract: A tissue repair material derived from fish skin and manufacturing method thereof is applied to provide the tissue repair material suitable for use as a patch, a cover, a carrier, a scaffold, an implant or a reagent in various tissues. The tissue repair material has collagens to improve the wounded tissue repair, and has particular characters for desired tissue repair application. Furthermore, so far the factors of the terrestrial animal transmitted disease (caused by virus) do not survive on the tissue repair material derived from fish skin.
