ESI O-cluder
ESI O-cluder ... Endovascular Eloquence
The ESI O-cluder is the latest innovation in minimally-invasive aneurysm treatment.
A novel, eloquent, and industry-changing device, the ESI O-cluder overcomes many of the limitations of the current endovascular method of treating aneurysms: coiling.
The thin, hourglass-shaped design of the ESI O-cluder provides superior treatment for most of the aneurysms that coils currently treat.
Like coiling, the ESI O-cluder is delivered endovascularly and works by reducing the circulation of fresh blood into the aneurysm, triggering a thrombus that allows the healing process to begin.
The similarities between the ESI O-cluder and coiling, however, end there.
Ease of Delivery
The ESI O-cluder, a small dumbbell or hourglass-shaped gold balloon, is compacted for endovascular delivery via catheter.
After delivery, with one lobe inside the aneurysm and the other lobe contained in the artery, the compacted ESI O-cluder is pressure expanded, inflating the ESI O-cluder to its original shape.
A simple mechanical collapse of the ductile gold lobes follows, forming a pop-rivet-like structure that captivates the neck of the aneurysm and reduces blood circulation into the aneurysm.
Finally, a balloon catheter contours the collapsed ESI O-cluder to the arterial wall, fully opening the parent artery.
Efficiency and Efficacy
The entire ESI O-cluder deployment procedure requires much less time than coiling, thereby reducing stress on the patient and physician, while also drastically reducing the cost.
By minimizing the amount and number of objects inserted into the aneurismal sac, the ESI O-cluder decreases the possibility of complications resulting from perforation of the aneurismal sac, and by eliminating the danger of coils protruding into the parent artery, the ESI O-cluder prevents the formation of a partial blockage that may lead to clot and stroke.
Eliminates the Mass Effect
Furthermore, the ESI O-cluder reduces the mass effect by eliminating the permanent lump of coils contained within the aneurysm that maintains an undesirable pressure on the surrounding brain tissue.
The design of the ESI O-cluder also allows for the removal of blood from the aneurysm through the catheter, reducing the size of the aneurysm.
Moreover, as time passes, the thrombus may be slowly absorbed, further reducing pressure on the surrounding tissue.
Eradicates Recanalization
Finally, and most importantly, the collapsed lobes of the ESI O-cluder completely cover the neck of the aneurysm, virtually eliminating recanalization: the reformation of the aneurysm at its neck.
Recanalization occurs in approximately 15 percent of coiled aneurysms and in nearly 50 percent of coiled giant aneurysms.
The virtual elimination of recanalization, the reduction of the mass effect, and the superior efficiency and affordability of the ESI O-cluder clearly places it well ahead of all other aneurismal treatments.
