摘要： A vascular implant, comprising a sheet comprising thin film nickel titanium (NiTi), wherein the sheet has at least one super-hydrophilic surface having a water contact angle of less than approximately 5 degrees. The sheet is configured to have a compacted form having a first internal diameter and a deployed form having a second internal diameter larger than the first internal diameter. The sheet may be delivered into a blood vessel in the compacted form and expanded to its deployed form at a treatment location within the blood vessel, wherein the stent is configured to expand onto an internal surface of the blood vessel and exert a radial force on said internal surface.

摘要： An intralumenal implant material, which comprises, a polymer having a sol-gel transition temperature in an aqueous solution thereof, shows a substantial water-insolubility at a temperature higher than the sol-gel transition temperature, and shows a thermo-reversible water-solubility at a temperature lower than the sol-gel transition temperature. Such an intralumenal implant is capable to be endovascularly or percutaneuosly delivered into a vascular lumen in a liquid state at the temperature lower than the sol-gel transition temperature, is capable to be instantly converted into a gel state in the vascular lumen at the blood temperature higher than the sol-gel transition temperature and is capable of occluding aneurysms, vascular tumors or vascular malformation. Such intralumenal implant material shows excellent biocompatibility and mechanical matching for the vascular tissue and the surrounding tissue because it is a highly water-containing hydrogel. In addition, biologically active substances for promoting a prompt neo-endothelium formation and/or endothelialization can be easily incorporated into such an intralumenal implant material.
