Diametrically Adjustable Endoprostheses And Associated Systems And Methods

Patent No. EP3445282 (titled "Diametrically Adjustable Endoprostheses And Associated Systems And Methods") was filed by W L Gore & Associates on Apr 21, 2016. The application was issued on Jun 28, 2023.

Patent Summary

A diametrically adjustable endoprosthesis for treating conditions such as portal hypertension, comprising a self-expanding stent-graft and a controlled expansion element that constrains the stent-graft's expansion. The controlled expansion element can be adjusted to a desired diameter, and once set, maintains that diameter under physiological conditions. The endoprosthesis can be deployed in a constrained state and then expanded to a larger diameter, with the controlled expansion element limiting further expansion. The device enables dynamic adjustment of the endoprosthesis diameter to achieve optimal fluid flow and pressure management.
