Embodiment Construction

[0041] like figure 1 and figure 2 As shown, the therapeutic apparatus for human lumen diseases includes a delivery tube 1 , a catheter hub 2 and a delivery wire assembly, and the delivery tube 1 communicates with the delivery wire assembly through the catheter hub 2 . The delivery wire assembly includes a soft grid tubular structure 4, a three-way sealing valve 7, a guide tube 5 and an introduction wire 6 connected in sequence, and one end of the guide tube 5 is connected to the said guide tube 5 through the three-way sealing valve 7 and the connecting seat 3. The catheter base 2 is connected, and the other end of the guide tube 5 is connected with an introduction wire 6 . The grid tubular structure 4 is arranged at one end close to the catheter base 2 , and the surface of the grid tubular structure 4 is coated and has micropores.

[0042] In this embodiment, the material of the grid tubular structure 4 includes natural protein, biological polysaccharide material, synthetic...

Abstract

The invention relates to a treatment instrument used for a human body lumen disease. The treatment instrument comprises a delivery tube, a catheter base and a wire delivery assembly. The wire delivery assembly comprises a grid tubular structure, a three-way seal valve, a guide tube and a lead-in wire. The grid tubular structure is arranged at one end close to the guide tube base, a coating is arranged on the surface of the grid tubular structure, micro holes are formed in the coating, and the coating comprises medicines, anti-coagulation substances, anti-bacterial substances, substances for promoting vascularization or substances for restraining the vascularization, so that different purposes of treatment are achieved. The defects of a spring coil and a covered stent are overcome, the normal anatomical structure of the vessels is reconstructed, and besides normal blood supplying of the collateral branch vessels is not affected. The treatment instrument has the advantages that a reliable entire occlusion rate of the radiography is obtained; a long-term stable effect is achieved; the treatment instrument is especially suitable for treating most of complex arterial aneurysms; complications at the later period are few; safety is high. The operation process is simple, cost is saved, and wide market prospects and good social effects are achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a therapeutic device for human body lumen diseases. Background technique [0002] In the past 30 years, the interventional treatment of aneurysms in the human body's natural lumen has achieved rapid development. For example, in the field of blood vessels, the main existing materials and technologies for interventional therapy include: (1) covered metal stents for the treatment of aneurysms, by implanting covered metal stents in the aneurysm cavity to isolate the aneurysm from the vascular circulation. The technology has been approved by the US FDA; (2) various improved coils, including surface modification, biological modification, etc., aiming at improving the dense embolization rate and healing rate; (3) multi-catheter embolization technology, balloon-assisted technology and stent Auxiliary embolization technology, which can prevent the coil from protruding into the pa...
