Title: David F Leighton: Innovations in Endoscopic Catheter Technology
Introduction:
In the field of medical device innovation, David F Leighton has made significant contributions with his expertise in endoscopic catheter technology. Hailing from West Lawn, PA (US), Leighton has earned commendation for his extensive patent portfolio, particularly in the realm of multi-lumen endoscopic catheters. This article delves into his latest patents, career highlights, and collaborations that have shaped the field of endoscopic catheterization.
Latest Patents:
David F Leighton's recent breakthrough in endoscopic catheter technology lies in the development of the multi-lumen endoscopic catheter. These catheters are specifically designed for the advancement through the accessory channel on an endoscope into the gastrointestinal system. The key feature of these catheters is the presence of two or more independent lumens extending continuously to ports at the distal tip.
These multi-lumen catheters allow for the injection of contrast medium simultaneously with a guide wire, enabling efficient ERCP (endoscopic retrograde cholangiopancreatography) procedures. Furthermore, they provide a pathway for the passage of various accessories, including visualization devices, polypectomy snares, cytology brushes, papillotomes, and stone baskets, thus facilitating catheterization, diagnosis, and treatment within the biliary tract.
Leighton's patents also reveal the employment of balloons to maintain a catheter in a fixed position within the biliary tract, as well as for dilation purposes. These catheters are typically extruded from a resin comprised of nylon and PEBA, while polyurethane is also used as an alternative material. Additionally, Leighton has developed multi-lumen catheters that feature a reduced diameter distal tip portion with a dilatation balloon, which can also serve as a platform for the support of a stent.
Career Highlights:
Throughout his career, David F Leighton has brought invaluable expertise to prominent companies in the medical device industry. He has notably worked with Arrow Precision Products, Inc., a company specializing in precision medical instruments. Leighton's contributions to this company have undoubtedly played a role in advancing endoscopic catheter technology.
