THIN FILM VASCULAR STENT AND BIOCOMPATIBLE SURFACE TREATMENT

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.
