Problems solved by technology

[0006] The aforementioned liquid embolic agent using solvent-insoluble metal tantalum powder as a contrast agent found during postoperative follow-up that the contrast agent had sedimentation during the operation pushing process, and then remained in the human body, and there was metal artifact interference in the subsequent imaging In addition, the metal developer remaining in the human body will also bring inconvenience to life, for example, in some metal induction occasions, there will be misjudgment

Abstract

The invention relates to a liquid embolism composition and application thereof, a medical interventional instrument and an interventional therapy drug. The liquid embolism composition is a dispersed mixed solution, the dispersed mixed solution comprises a dispersing agent solution in a continuous phase and developable solid particles which are dispersed in the dispersing agent solution and are in a dispersed state, and the developable solid particles are provided with holes allowing the dispersing agent solution to enter. And the dispersing agent solution contained in the holes and the dispersing agent solution outside the developable solid particles form a continuous phase. Therefore, the loss of the developer caused by rapid diffusion of the solvent can be reduced, and the developer is effectively cured through the polymer, so that the developing and embolism performances of the liquid embolism composition are ensured.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a liquid embolism composition and its application, medical interventional devices and interventional therapy drugs. Background technique [0002] Interventional embolization is widely used in the clinical treatment of vascular abnormalities such as cerebral arteriovenous malformation (AVM) and cerebral arteriovenous fistula (DVF). Interventional embolization agent is a reagent required for interventional embolization technology. It is a reagent that has the function of embolizing tumor blood vessels. It can form embolism in the lumen of tumor blood vessels, and then block the lumen of blood vessels, and finally achieve tumor ischemia. and necrotic purposes. [0003] At present, there are many types of interventional embolic agents, classified according to their status, including solid embolic agents and liquid embolic agents. Although the embolization process of solid e...
