Aortic Graft Occluder

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention concerns an aortic graft occluder, a medical device designed for use during heart surgeries such as valve-sparing aortic root replacements. The device functions as a plug that can seal the open end of a tubular aortic graft (a vascular prosthesis) during surgery. It features pathways that allow fluid injection and/or pressure monitoring, enabling surgeons to test for leaks at the surgical connection between the graft and the patient's vessel before completing the procedure. This intraoperative testing ensures the graft and sutures are leakproof and the aortic valve functions correctly, reducing the need for additional corrective surgeries.

Use CasesContent extracted from patent full text and abstract with AI.

• Leak testing of aortic grafts during valve-sparing aortic root replacement surgery.
• Intraoperative assessment of graft connections in repairs for aortic aneurysms or other vascular reconstructions.
• Pressurization of grafts to simulate physiological conditions to test for leaks before restoring blood flow.
• Facilitating imaging-based testing (e.g., ultrasound) of aortic valve functionality while the graft is being assessed for leaks.
• General use in surgical installation of vascular prostheses involving tubular grafts that require verification of leak-tightness.

BenefitsContent extracted from patent full text and abstract with AI.

• Allows immediate detection and correction of leaks during surgery, improving patient safety.
• Reduces the likelihood of post-surgical complications associated with undetected leaks, such as bleeding or need for re-operation.
• Saves time and resources by preventing repeated clamping and re-establishment of circulation.
• Enables accurate pressure simulation and verification under controlled, safe conditions (up to and above normal physiological pressures).
• Minimizes patient risk and surgical stress by allowing for precise and non-destructive testing before concluding the operation.
• Enhances surgical workflow through standardized connectors and user-friendly design features, including secure and flexible attachment methods.
• Adaptable to a wide range of graft types and diameters, supporting various surgical preferences and patient anatomies.

Patent Abstract

The present invention relates to an aortic graft occluder for intraoperative leak testing of a tubular aortic graft attached to an aortic root, the aortic graft occluder comprising a plug adapted for sealingly closing an opening of the aortic graft, wherein the plug comprises a first pathway adapted for connecting a lumen of the aortic graft with a feed line.
