An innovative microcatheter-delivered vascular device provides rapid and focal occlusion of a wide range of peripheral arterial targets.

The Okami Medical (Aliso Viejo, CA, USA) LOw-profile Braided Occluder (LOBO) is a minute embolic device that is designed to occlude a blood vessel by self-expanding when deployed. A unique braiding method that uses wires less than 20 microns in diameter--about ¼ the thickness of a human hair--and a multiple-disk design provide LOBO with a dense-pore scaffold structure that spans the vessel lumen, rapidly reducing flow and accelerating hemostasis in vessels as small as 1.5 mm. Other features include radiopaque marker bands for visualization and instantaneous mechanical detachment.

To provide smooth navigation throughout the peripheral vasculature, the microcatheter-compatible occluder employs a three-disc design that provides excellent trackability in small, tortuous vessels, which allows conformance to curved vessels and focal occlusion. The intuitive, single-click mechanical detachment handpiece allows for precise, instant release of the occluder at the target location and retrievability, if necessary. The device is not indicated for use in blood vessels where crush or bend forces are anticipated, such as in joint areas and superficial vasculature.

“The Okami team brings more than a decade of leadership in braiding technology and minimally invasive vascular solutions,” said Bob Rosenbluth, PhD, President and CEO of Okami Medical. “The LOBO system is uniquely designed to provide a one-and-done solution for many occlusion targets, thus potentially avoiding the need for several embolic devices and enabling more efficient interventions.”
