Occlusion system for left atrial appendage
A newly granted patent (Publication Number: US12011174B2) discloses an innovative occlusion system designed for occluding a treatment site, such as in the heart. The system comprises an outer catheter with an elongated body and at least one lumen, an inner catheter radially positioned within the outer catheter, a detachable balloon at the distal end of the outer catheter, and an adhesive-absorbing membrane at the distal portion of the balloon. The membrane is engineered to absorb a specific volume of adhesive delivered through the inner catheter and expose it on the membrane's outer surface. The system's unique design and components aim to enhance the occlusion process effectively and efficiently.
Furthermore, the patent details various configurations and features of the occlusion system, including the composition and structure of the adhesive-absorbing membrane, the valves within the balloon to control fluid flow, and the method for occluding blood flow in a left atrial appendage in a patient's heart. The system's valves prevent inflation fluid from entering the adhesive-containing depression of the balloon, ensuring precise delivery of adhesive to the treatment site. The method outlined in the patent involves advancing the balloon, inflating it, delivering adhesive, absorbing it with the membrane, and detaching the outer catheter. These claims highlight the system's intricate design and functionality, showcasing its potential for improving occlusion procedures in medical settings.
