Human body lumen therapeutic device

Abstract

The invention relates to a human body lumen therapeutic device which comprises a delivery tube, a guide tube seat and a delivery wire component. The delivery wire component comprises a grid tubular structure, a three-way seal valve, a guide tube and a guide wire, the grid tubular structure is arranged at one end close to the guide tube seat, a coating and micropores are arranged on the surface of the grid tubular structure, and the coating comprising medications, anticoagulants, antibiotic substances, angiopoiesis promoting substances or angiopoiesis inhibiting substances so as to achieve different therapy purposes. By the human body lumen therapeutic device, defects of a spring ring and a covered stent are overcome, a normal vascular anatomical structure is reconstructed, and normal blood supply of collateral vessels is unaffected. The human body lumen therapeutic device has the advantages that reliable arteriography total occlusion rate is obtained; and the human body lumen therapeutic device has long-term stability effect, and is particularly suitable for therapy of most complicated aneurysms, less in late complications and high in safety. Besides, the human body lumen therapeutic device is simple in surgery process and cost-saving, and has broad market prospects and excellent social effects.

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...

AI Technical Summary

Problems solved by technology

[0004] The interventional treatment of existing aneurysms mainly faces two major problems: the long-term stability needs to be improved (that is, the imaging recurrence rate is high), and the treatment of refractory aneurysms

[0005] Existing covered stents are used in endovascular exclusion of aneurysms, which can achieve real parent artery reconstruction, but its disadvantage is that it is limited to the treatment of aneurysms without important branch arteries
