Problems solved by technology

[0003] However, the fragile and non-linear nature of the neurovascular vessels limits the suitability of such stents in, for example, procedures to repair neurovascular defects
Furthermore, known delivery methods are less useful in vessel occlusion surgery, especially in the treatment of tiny vessels such as those present in the brain

Abstract

The present invention discloses an expandable ring for a braided stent. The present invention provides a braided stent system comprising expandable rings attached to the interior and exterior surfaces of a lumen. A frame of the ring may impart a radial force to expand the lumen outward, the frame comprising a plurality of joints joined at a connector and at first and second intersections opposite the connector. Slender member. A clamp is extendable from the intersection and is operable to slidably secure the frame to the inner surface and the outer surface of the lumen.

Description

technical field [0001] The present disclosure relates generally to treating certain defects in a patient's vasculature, and more particularly to expanding a braided stent to a treatment site in a patient's vasculature. Background technique [0002] A stent may be understood as a tubular reinforcement insertable into a blood vessel to provide an open path within the blood vessel. Stents have been widely used for endovascular angioplasty treatment of blocked heart arteries, during which a stent may be inserted after angioplasty to prevent restenosis of the artery. Stents are often deployed using a delivery device that opens the stent to strengthen the artery wall and provide a clear path through the artery to prevent restenosis. [0003] However, the fragile and non-linear nature of neurovascular vessels limits the suitability of such stents in, for example, procedures to repair neurovascular defects. Furthermore, known delivery methods are less useful in vessel occlusion su...
