Title: Philip J. Haarstad: Inventor of an Incisionless Gastric Bypass System

Introduction

Philip J. Haarstad is an inventor associated with Chanhassen, Minnesota. His work includes a patent for an endoscopic system designed to form an anastomosis between naturally adjacent points in the digestive tract.

Latest Patents

Haarstad’s listed patent is “Incisionless gastric bypass system.” The invention uses elongated magnetic devices connected across a tissue boundary. The magnets cause the intervening tissue to necrose until an anastomosis forms, after which the devices pass naturally through the body. Although the devices are elongated, the resulting anastomosis is substantially round. Increasing the devices’ length can create a larger-diameter opening without requiring a wider endoscope. Haarstad is credited with 1 patent.

Career Highlights

The gastric bypass system represents Haarstad’s contribution to endoscopic medical technology. Its design aims to form a digestive-tract connection without conventional incision-based surgery while addressing the practical limits of endoscope size.

Collaborations

Haarstad’s listed coworkers include David J. Blaeser and Todd A. Krinke.

Conclusion

Philip J. Haarstad’s patented system applies magnetic devices to create a substantially round anastomosis endoscopically, offering a design intended to enlarge the opening without requiring a wider endoscope.
