Title:
INTRATUMOR TURBULENT FLOW DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/247145
Kind Code:
A1
Abstract:
The present invention relates to an intratumor turbulent flow device, comprising: a turbulent flow net disc of a double-layer metal wire braided structure, wherein a developing mark is provided at the bottom in the center of the turbulent flow net disc, and metal wires in the center of the turbulent flow net disc are fixed in the developing mark; the center of the turbulent flow net disc is protruded upwards; the bottom end of the developing mark does not exceed the lowest end of the turbulent flow net disc; a release portion, a distal end of the release portion being fixedly connected to the developing mark; a pushing guide wire, the pushing guide wire being connected to the turbulent flow net disc by means of the release portion, and being used for pushing the turbulent flow net disc; and a microcatheter used for transporting the turbulent flow net disc. The pushing guide wire pushes, into a tumor cavity of the aneurysm along the microcatheter, the turbulent flow net disc compressed to be bundle-shaped. The turbulent flow net disc expands in the tumor cavity and is fitted to the inner wall of the tumor cavity. The release portion is broken by electrolysis or electric heating, so that the center of the turbulent flow net disc is restored to be protruded for pulling the developing mark into the tumor cavity, and thus the developing mark is prevented from forming an embolism in the blood vessel.
