MEDICAL DEVICE FOR OCCLUDING A LEFT ATRIAL APPENDAGE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240016496 titled 'MEDICAL DEVICE FOR OCCLUDING A LEFT ATRIAL APPENDAGE
Simplified Explanation
The abstract describes a medical implant designed to occlude a left atrial appendage. It consists of an expandable framework that can transition between a collapsed and expanded configuration, and an occlusive element attached to the framework. The expandable framework includes a proximal hub and interconnected struts that form a main body in the expanded configuration. Additionally, the framework has elongate anchoring appendages with anchoring barbs extending from them.
- The implant is used to block or close off the left atrial appendage in the heart.
- It can shift between a collapsed and expanded configuration, allowing for easier insertion and deployment.
- The expandable framework provides structural support and stability to the implant.
- The occlusive element ensures effective occlusion of the left atrial appendage.
- The elongate anchoring appendages with anchoring barbs help secure the implant in place.
Potential Applications
- Treatment of atrial fibrillation: The implant can be used to reduce the risk of blood clots forming in the left atrial appendage, which is a common source of stroke in patients with atrial fibrillation.
- Stroke prevention: By occluding the left atrial appendage, the implant can help prevent blood clots from entering the bloodstream and causing a stroke.
- Cardiac surgery: The implant may be used during cardiac surgeries to close off the left atrial appendage and reduce the risk of complications.
Problems Solved
- Stroke risk reduction: The implant addresses the problem of blood clots forming in the left atrial appendage, which can lead to strokes.
- Invasive procedures: By providing a minimally invasive solution, the implant reduces the need for more invasive surgical procedures to occlude the left atrial appendage.
- Long-term anticoagulant use: Patients with atrial fibrillation often require long-term anticoagulant medication to prevent blood clots. The implant offers an alternative solution that may reduce or eliminate the need for such medication.
Benefits
- Minimally invasive: The implant can be inserted and deployed using minimally invasive techniques, reducing the risks and recovery time associated with open-heart surgery.
- Effective occlusion: The expandable framework and occlusive element ensure reliable and secure occlusion of the left atrial appendage.
- Potential reduction in stroke risk: By blocking the left atrial appendage, the implant may help reduce the risk of stroke in patients with atrial fibrillation.
- Improved patient outcomes: The implant may offer a less invasive and more convenient treatment option for patients, potentially improving their quality of life.
Original Abstract Submitted
a medical implant for occluding a left atrial appendage may include an expandable framework configured to shift between a collapsed configuration and an expanded configuration, and an occlusive element secured to the expandable framework. the expandable framework includes a proximal hub and a plurality of interconnected struts extending from the proximal hub, the plurality of interconnected struts defining a main body in the expanded configuration. the expandable framework includes a plurality of elongate anchoring appendages extending from the main body, the plurality of elongate anchoring appendages each including a plurality of anchoring barbs extending therefrom.
