EMBOLUS FORMING IN-VIVO INDWELLING IMPLANT

摘要

The invention provides an embolus forming in-vivo indwelling implant capable of being reliably indwelled in a predetermined region and allowing re-indwelling operation to be reliably performed, thus having high safety and high operability. The invention is an embolus forming in-vivo indwelling implant comprising an axial extension control member having a predetermined degree of tensile break strength and disposed in a coil main body having pliability, the axial extension control member being fixed to a coil through a loop made of a material thicker than a wire that constitutes an axial extension control member disposed at the far-side end of the coil main body. The axial extension control member, the loop and the coil main body are preferably made of the same metal material, such as platinum alloy, and the axial extension control member is preferably formed of stranded wire.
