3 results about "Aneurysm treatment" patented technology

This invention provides an aneurysm embolization auxiliary device, belonging to the field of medical device technology. The device includes a delivery catheter, an operating handle, a balloon, and a filling unit. The delivery catheter delivers a treatment device to the aneurysm location. The operating handle is located at the proximal end of the delivery catheter. The balloon, after inflation, supports the blood vessel. The filling unit fills the aneurysm with an injectable gel for treating the aneurysm from the operating handle location along the delivery catheter. The injectable gel solidifies within the aneurysm. During operation, the delivery catheter delivers the balloon to the aneurysm location. After inflation, the balloon supports and positions the blood vessel. The filling unit fills the aneurysm with the injectable gel, which solidifies upon entering the aneurysm to treat it. This invention primarily addresses technical problems in existing interventional aneurysm treatment methods, such as easy displacement of coils and the increased risk of bleeding due to the need for long-term medication after stent implantation.

Method of endovascular treatment of an aneurysm having a sac with a neck in fluid communication with a parent vessel. A delivery catheter is navigated through the vasculature to the aneurysm. Next, a delivery system is advanced through the delivery catheter to the aneurysm. A liquid metal embolic is injected via the delivery system into the aneurysm with the injected liquid metal embolic at least partially filling the aneurysm. Optionally, a liquid metal embolic seepage preventative element (e.g., radially self-expanding braided structure or plurality of radially self-expanding coils) may be deployed in the aneurysm prior to the injection of the liquid metal embolic prohibiting the liquid metal embolic injected in the aneurysm from entering the parent vessel.

Treatment of aneurysms can be improved by delivering an occlusive member (e.g., an expandable braid) to an aneurysm sac in conjunction with an embolic element (e.g., coils, embolic material). A treatment system for such treatment can include an electrolytically corrodible core wire having a proximal portion, a distal portion, and a detachment zone between the proximal portion and the distal portion. An occlusive member having a proximal hub is coupled to the core wire distal portion. A conduit extends along at least a portion of the core wire. The conduit has a lumen configured to pass an embolic element therethrough.
