Title: Albertien Greijdanus and a Transcatheter Approach to Interatrial Anastomosis.

Introduction

Albertien Greijdanus is an inventor associated with Houston, Texas, and the Texas Medical Center. His patent work addresses a catheter-based approach to treating heart failure by reducing elevated pressure in the left atrium.

Latest Patents

Greijdanus is credited with 1 patent: “Transcatheter Device for Interatrial Anastomosis.” The patent describes a device assembly and method for creating a sized opening in the interatrial septum, the wall between the heart’s left and right atria. The opening is intended to help relieve elevated left atrial pressure.

The disclosed assembly includes a delivery catheter, a tissue stabilizer, and a cutter. The stabilizer is attached to a catheter with a central lumen and a penetrating tip that allows a guidewire to pass through. The cutter is attached to a second catheter, whose lumen accommodates the first catheter. Alternative configurations may include an additional catheter for access to and from the right atrium, a tissue-retention mechanism, and an optional coaxial alignment mechanism.

Career Highlights

The patent reflects work on a transcatheter technique designed to create an interatrial aperture without relying on open-heart surgery. Its components are arranged to stabilize tissue and guide the cutting process, with the goal of producing an opening of a selected size.

Collaborations

Greijdanus’s listed coworkers include Christopher Alexander Arevalos and Jacob Kriegel. The patent information provided does not specify their individual roles or contributions.

Conclusion

Albertien Greijdanus’s patent describes a catheter-based device for creating an interatrial opening intended to relieve elevated left atrial pressure, highlighting his contribution to an interventional approach to heart failure treatment.
