AI Technical Summary
Technical Problem
Current self-expanding vascular devices face challenges in maintaining a stable throat diameter after implantation, as they are prone to excessive compression or expansion, which affects the flow restriction effectiveness and clinical applicability.
Method used
The design incorporates a self-expanding tubular structure with a stabilized throat portion, achieved by varying the cell angle within the throat section to minimize diameter changes and enhance stability, allowing for controlled flow restriction.
Benefits of technology
The stabilized throat maintains consistent diameter and flow restriction, preventing excessive compression or expansion, thereby improving the device's effectiveness and clinical suitability.

Abstract
A self-expanding implant useful as a vascular flow reducer is disclosed. This implant has a variable cell angle and limits the amount of diameter change in a specific part of the implant (e.g., the throat or the inner diameter of the central throat of an hourglass shape). A method for fabricating such an implant is also described.
