Title: Innovations by Frederick S Keller in Medical Devices
Introduction
Frederick S Keller, an accomplished inventor based in Portland, OR, has contributed significantly to the field of medical devices, holding a remarkable total of 11 patents. His innovative designs are instrumental in advancing health care technology, particularly in vascular and occlusion devices.
Latest Patents
Keller's latest patents include two groundbreaking inventions aimed at improving medical treatments. The first is a multi-stage occlusion device, which features a covering attached to a support frame that comprises a disc-shaped member and a crossbar. This occlusion device can transition between two configurations: a deployed state, where the crossbar forms a curve extending from the disc, and a resting state, where both components lie nearly flat. Each part includes a core wire threaded through a coil multiple times, ensuring durability and effectiveness.
His second notable invention is an implantable vascular device, which features a resilient frame with a series of bends that can transform from a flat configuration to a serpentine shape. This device is designed to be pushed through a delivery catheter into the lumen of a vessel and may contain barbs for secure anchoring. Additionally, it can be covered with materials such as DACRON, PTFE, or collagen-based substances like small intestinal submucosa (SIS), making it suitable for applications such as stent grafts or intraluminal valves to treat incompetent veins.
Career Highlights
Frederick S Keller has also collaborated with notable companies such as Cook Incorporated and Oregon Health & Science University. His work has significantly impacted medical practices, driving innovation in vascular and occlusion technologies that are now utilized in various clinical settings.
