Latest Advancements Launched for Penumbra's Stroke Thrombectomy Aspiration Technology
September 4, 2018—Penumbra, Inc. announced commercial availability in the United States of the company's Jet 7 and Jet D reperfusion catheters powered by the Engine aspiration source. The devices are part of the company's fully integrated Penumbra System, which utilizes aspiration-based mechanical thrombectomy for stroke revascularization. The Jet 7 and Jet D reperfusion catheters deliver the deep vacuum aspiration power of the Engine to enable physicians to safely and effectively extract thrombus in acute ischemic stroke patients.
According to the company, the Jet 7 is the Penumbra System’s seventh-generation reperfusion catheter for proximal large vessel occlusions, and the Jet D reperfusion catheter is specifically designed for distal occlusions. The Jet 7 reperfusion catheter has a large 0.072-inch lumen for deep vacuum aspiration and is designed for trackability and navigation, featuring 20 transitions from the proximal shaft to distal tip, a progressive distal coil wind for flexibility, and Quad-Wire technology in the proximal shaft for enhanced pushability. Jet D brings deep vacuum aspiration power to distal occlusions with a smaller profile.
As the third-generation aspiration source, Engine provides the deepest vacuum available (-29.2 in Hg) with the Penumbra System. It also features a new design with one-touch aspiration control, a new canister with integrated clot catcher, and LED canister lighting. With the new devices, the Penumbra System Engine offers a high thrombus removal force for revascularization of acute ischemic stroke patients with large vessel occlusions, stated the company.
In Penumbra's press release, Alejandro M. Spiotta, MD, commented, “The Jet 7 reperfusion catheter with its advanced tracking technology and large 0.072-inch aspiration lumen is the most advanced device for stroke. In my clinical experience, I was able to easily and quickly navigate the Jet 7 through tortuous anatomy to the face of the clot and achieve full revascularization after a single pass."
Dr. Spiotta, who is with Medical University of South Carolina in Charleston, South Carolina, continued, "We know from our own published experience that increases in aspiration lumen size have led to faster recanalization times and higher likelihood of success at first pass without compromising safety. I eagerly await collecting and publishing our clinical experience with Jet 7.”
Ian Kaminsky, MD, also commented in the company's announcement, “The Jet 7 and Jet D along with the new Engine provide a suite of tools to effectively address both proximal and distal occlusions." He added, "In our initial case experience, we saw the easy tracking of the Jet 7 and Jet D in a range of tortuous conditions and vessel locations that, combined with the deep vacuum of the Engine, offer the potential to increase our rate of complete first pass revascularization while decreasing procedure times.” Dr. Kaminsky is with Radiology Imaging Associates/Swedish Medical Center in Englewood, Colorado.
