Title: Nasser William Saleh and His Expandable Sheath Invention.

Introduction

Nasser William Saleh is an inventor associated with Stockton, California, and Edwards Lifesciences Corporation. His patent work includes an expandable sheath designed to help introduce endovascular delivery devices into the body.

Latest Patents

Saleh is named on 1 patent: “Expandable Sheath for Introducing an Endovascular Delivery Device into a Body.” The invention describes a sheath used with a catheter assembly to deliver a prosthetic device, such as a heart valve, into a patient.

The sheath can temporarily expand to accommodate the delivery apparatus and then return to its original diameter after the prosthetic device passes through. In some examples, it has inner and outer layers, with a folded portion of the inner layer extending through a slit in the outer layer. An overlapping portion of the outer layer and an optional elastic outer cover help form the expandable structure.

By allowing temporary expansion, the design aims to reduce vessel trauma and avoid multiple insertions to dilate the vessel, offering an alternative to prior-art introducer sheaths.

Career Highlights

Saleh’s listed patent reflects work on medical-device technology for endovascular procedures. The invention focuses on adapting an introducer sheath to accommodate a prosthetic delivery system while limiting the need for repeated vessel dilation.

Collaborations

Saleh is associated with Edwards Lifesciences Corporation. His named coworkers include Leah Paige Gaffney and Erik E. Bulman.

Conclusion

Nasser William Saleh’s patent describes an expandable introducer sheath intended to support prosthetic-device delivery while reducing vessel trauma and the need for multiple insertions.
