Embolism material composition as well as preparation method and use thereof

Abstract

The invention provides an embolism material composition as well as preparation method and use thereof, the embolism material composition is prepared from reactant raw materials, wherein the reactant raw materials comprise a biocompatibility material, a roentgenopaque substance and a magnetic resonance imaging substance, the roentgenopaque substance and the magnetic resonance imaging (MRI) substance are covered by the biocompatibility material. The embolism material composition not only can be directly detected by an X-ray image device, but also can be directly detected by the MRI, so that a doctor can select a detection method according to self condition of a patient and the medical device condition.

Description

technical field

[0001] The invention belongs to the field of interventional medicine, and in particular relates to an embolic material composition, a preparation method and application thereof. Background technique

[0002] Interventional embolization therapy refers to the introduction of embolic agents into the human body through precision instruments such as special guide wires and catheters for local treatment under the guidance of medical imaging equipment. Embolization therapy has achieved good results in the treatment of uterine fibroids, liver cancer, kidney cancer, hemangioma, vascular malformation and hemostasis, and has become an alternative to partial surgical treatment.

[0003] Currently clinically used embolic agents, such as polyvinyl alcohol irregular particles or microspheres, gelatin sponge irregular particles or microspheres, etc., cannot be detected by X-ray imaging equipment (including digital Subtraction Angiography, DSA) and computed tomography (Compu...
