Title: Amy L. Foley: Innovator in Membrane Technology and Artificial Pancreas Development
Introduction
Amy L. Foley is a prominent inventor based in Framingham, MA (US). She has made significant contributions to the fields of membrane technology and biomedical devices. With a total of 2 patents, her work focuses on innovative solutions that enhance productivity and improve health outcomes.
Latest Patents
Foley's latest patents include a "Method and apparatus for casting hollow fiber membranes" and an "Artificial pancreatic perfusion device." The first patent describes an automated system for casting hollow fiber membranes into various shapes, such as spiral, linear, circular, and rectangular. This system allows for configuration changes during casting, which increases productivity. It utilizes a co-extrusion die that is rotated over a stationary coagulation bath, with a computer controlling the die's motion to achieve the desired membrane shape. The nozzle design compensates for distortions in wall thickness, resulting in a uniformly symmetric wall thickness.
The second patent, the "Artificial pancreatic perfusion device," features a hollow fiber with an inner diameter of about 5 mm, surrounded by islets of Langerhans enclosed in a housing. The islets are suspended in a semi-solid matrix, ensuring optimal distribution around the hollow fiber. This device selectively allows the passage of substances with a molecular weight of less than about 100,000 Daltons, utilizing materials such as alginate or agar for the semi-solid matrix.
