Use of Catheter Rail System for Delivery and Deployment of a Graft Device for the Ascending Aorta

Tech ID: sie000702

 

Introduction

This device assists surgical treatment of aneurysm and dissection of the ascending aorta. Aneurysm and dissection are potentially life threatening conditions in which a blood vessel becomes compromised. An aneurysm is an enlargement of the vessel which can burst and cause internal bleeding. A dissection is a tear or branch in a vessel wall through which blood can flow into surrounding tissues. Large arteries close to the heart may be at a higher risk for aneurysm and dissections due to higher and more variable pressures. Further, the internal bleeding caused by these conditions can become massive and rapid, with potentially life-threatening repercussions for the patient.

 

Description

Treating aneurysms in the upper sections of the heart can be quite challenging. Typically, catheter-based treatments of the descending aorta are known, however these procedures are not well adapted for treating dissections or aneurysms of the ascending aorta. A significant risk of these surgical procedures is that the catheter will go down the wrong path, causing severe bleeding in the aorta. Dr. Siegel’s device provides a stable rail system so a stent graft can easily be placed on the ascending aorta, reducing the risk of an unstable catheter going down the wrong path and causing bleeding or other complications.

 

Stage of Development

Concept only.

 

Advantages/Novelty

The device provides for repair of aneurysms in the ascending aorta, which is typically quite challenging.

 

Applications

The concept can be developed into a vascular graft device for treatment of aneurysms and dissections in the ascending aorta.
