Title: Donal F. Manley and Radiopaque Cobalt-Based Implant Materials.

Introduction

Donal F. Manley is an inventor associated with Cork, Ireland, and Abbott Cardiovascular Systems, Inc. His patent work addresses the processing of cobalt-based alloys for radiopaque implantable structures, including stents.

Latest Patents

Manley is associated with 1 patent, titled “Processing of Cobalt-Tungsten Alloys.” The invention concerns cobalt-based alloys containing cobalt, chromium, tungsten, nickel, and platinum or another metal with a higher atomic number or density than cobalt. These materials are designed to improve radiopacity in implantable structures.

The patent describes heat treating the alloy to remove precipitate inclusions, including tungsten-rich precipitates, that could make the material unsuitable for stents or similar implants. It identifies a narrow treatment range centered around 1,250°C for approximately 30 minutes. According to the described process, higher temperatures or longer treatment times do not achieve the same result. The treatment substantially removes the inclusions and produces a more homogeneous structure suitable for implant use.

Career Highlights

Manley’s disclosed patent work focuses on materials processing for cardiovascular implants. The invention links precise heat-treatment conditions with improved alloy homogeneity and radiopacity, addressing material properties relevant to stent manufacture.
