Plug device for assisting aneurysmal neck

Abstract

The invention relates to a plug device for assisting an aneurysmal neck. The plug device comprises a microcatheter, a fixing guide wire, a developing guide wire, a plug device body and aids, wherein the developing guide wire is fixed on the aid at the far end of the plug device body; the fixing guide wire passes through insides of the aids and the microcatheter; two ends of the plug device body are funnel-shaped when the plug device body is in an unfolded state, and a conical angle ranges from 20-70 degrees; the plug device body adopts a meshed spatial solid structure woven by 8-20 memory metal wires, and ballooning-outs are formed by bulging of deformation of the metal wires at the middle parts of the plug device; the angle of the ballooning-outs is 110-160 degrees. The plug device for assisting the aneurysmal neck has the following advantages: the therapeutic safety is improved, and trauma is small; the plug device can be supported in a parent artery to assist a spring coil for plugging when the aneurysm is difficult to plug only by the spring coil, and the plug device can be recovered completely to be in vitro after plugging; the defect of ischemic complications caused by long-time blockage of blood flow in the parent artery is overcome when the plug device is compared with a balloon-assisted plug.

AI Technical Summary

Benefits of technology

This patented technology helps treat abnormalities (aneurism) inside or near them without causing damage during surgery. It involves inserting a special catheter into the patient's vasculature that extends from their heart to reach where there may bleeding due to any blockages within this vessel. A small tube called a stenotic plug is then inserted along the pathway create space around the blocked area. An elastic material like rubber fills these spaces, allowing the stem to expand smoothly when injected under pressure. When used properly, they help keep the treated section open up again preventing further problems such as rebleasing strokes or recurrence after angioplasty procedures. Overall, this technology provides better outcomes than existing methods but also reduces risk factors associated with traditional interventional therapies.

Problems solved by technology

There currently exist methods used to prevent narrowing of large vessel lumen due to plaque builation or inflammation associated with diseases like stroke or trauma. These techniques involve injecting liquid agents directly inside the affected area through small holes made in the wall's surface layer. They aim to reduce these issues while maintaining their effectiveness over longer periods.
