|1. (WO2018107355) POLYMER-BASED ARTERIAL HEMANGIOMA EMBOLIZATION DEVICE, MANUFACTURING METHOD AND APPLICATION OF SAME|
|Applicants:||BEIJING ADVANCED MEDICAL TECHNOLOGIES, INC.
|Inventors:||ZHAO, Hugh Qinghong
|Title:||POLYMER-BASED ARTERIAL HEMANGIOMA EMBOLIZATION DEVICE, MANUFACTURING METHOD AND APPLICATION OF SAME|
A polymer-based embolization device, comprising a helix constructed using a linear structure. The linear structure is either a fibrous structure or an assembly of an A structure (1) and a B structure (2), wherein the A structure (1) is a protrusion on the linear structure and the B structure (2) is a pillar-shaped structure positioned between two A structures (1) for connecting the two A structures (1). The embolization device adopts a linear structural design and is seamlessly manufactured using a polymer material via a four-axis rapid forming system or via a compression method, thereby addressing issues of generation of image artifacts during CT and magnetic resonance imaging. The design, material, and technique of the invention combine to provide the device with improved flexibility and embolus formation, and can satisfy different clinical requirements. When a biodegradable macromolecular material is selected for manufacturing, blood vessel obstruction caused by implant degrading can be avoided, allowing the blood vessel to return to a normal structural state.
