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.
