An apparatus and method for a micro-patterned thin film Nitinol (TFN) that is used as a cover for an expandable stent structure, and has elongation/expansion properties that are configured to match the elongation/expansion properties of the expandable stent structure is presented.

Apparatus and methods for bidirectional hyperelastic stent covers

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.

Thin film vascular stent and biocompatible surface treatment

A flow diverter is described and fabricated using ultra-thin porous thin-film Nitinol, and is configured for implantation to a treatment site within a vessel for significant reduction in an intra-aneurismal flow velocity and vorticity. Using small size pores in a coverage area of only 10%, a 90% reduction in flow velocity into a pseudo-aneurysm can be achieved, with an almost immediate cessation of flow into an anatomical feature such as aneurysm sac in vivo. The size of the holes can be tailored to be any shape and range in size from 1-400 &#x3bc;m using photolithography and from 5-1000 nm using ebeam lithography.
