Abstract: Scissors including a pair of shanks with one end forming an upper shear blade and a lower shear blade and with the other end of the pair of shanks forming handles, the handles being opened and closed centered about a pivot where the shanks intersect and causing the upper shear blade and lower shear blade to open and close, and screw for loosely fastening the pivot with a degree of freedom so that the screws do not interfere with sliding of the blades when cutting an object, at least one of the upper shear blade and the lower shear blade being formed by an alloy having an elastic deformation ability of 0.2% or more.

Abstract: The present invention provides scissors obtained by selecting materials sliding against each other, utilizing their springiness, enabling the shape of a blade to be followed so that a shear blade slides against the opposite shear blade, and can cut along the opposite blade. The present invention relates to scissors for medical use comprised of a pair of shanks with one ends forming an upper shear blade and a lower shear blade and with the other ends of the pair of shanks forming handles, the handles being opened and closed centered about a pivot where the shanks intersect and causing the upper shear blade and lower shear blade to open and close, at least one of the upper shear blade and the lower shear blade being formed by an alloy having an elastic deformation ability of 0.2% or more.

Abstract: It is an object of the present invention to provide a catheter, whereby a tunnel infection route is closed such that infection can be prevented, by improving adhesiveness between a medical catheter and a biologically-derived adhesive (fibrin adhesive), cells, or biological tissue. The present invention provides a medical catheter which is composed of material selected from the group consisting of silicone, polyurethane, polypropylene and polytetrafluoroethylene (PTFE), at least a portion of the surface of which is modified by plasma ion implantation.

Abstract: It is an object of the present invention to provide a polymer material, the histocompatibility of which has been improved by irradiation of ion beam, which prevents an aneurysm having a risk of rupture from actually rupturing. The present invention provides a material for treating aneurysms, which is composed of a polymer material containing carbon as a constitutional element, and which is produced by modifying at least a portion of the surface thereof by ion bombardment.

Abstract: An object of the present invention is to provide a means for improving the affinity of an in vivo embedded material such as an artificial blood vessel or an artificial dura mater with a tissue adhesive, so as to quickly prevent the leakage of the blood or spinal fluid. The present invention provides a polymeric material used in combination with a tissue adhesive, which comprises carbon or silicon as a constitutional element, and at least a portion of the surface of which is modified by ion bombardment.
