Problems solved by technology

At the same time, the existing drug balloon can infiltrate the drug into the vascular tissue through the filling of the balloon, but because the balloon blocks the blood flow, it can only be filled for about 40 seconds at most, otherwise it may cause myocardial ischemia, so the drug Limited release time and limited healing

Abstract

The invention discloses a drug eluting balloon system which comprises a balloon catheter and a drug eluting balloon, wherein the balloon catheter is provided with a wire guide cavity arranged along the axial direction; the drug eluting balloon is arranged along the partial length of the balloon catheter and is expanded by virtue of a pressure medium provided by the balloon catheter; the external surface of the balloon body of the drug eluting balloon is provided with a drug coating; the drug coating comprises an inner layer and an outer layer, wherein the inner layer is a taxol and hirudin mixed drug coating, and the outer layer is a hirudin drug coating; a flow channel is also arranged in the wire guide cavity, and the flow channel is arranged at the partial length position of the balloon catheter; and the flow channel is provided with two openings which are respectively formed in two ends of the drug eluting balloon. When the drug eluting balloon system releases drugs, blood flow can not be blocked and drug release can be prolonged to any time, so that the action time of the drugs is increased and the curative effect is improved.

Description

technical field [0001] The invention relates to a medical device. More specifically, the present invention relates to a drug eluting balloon system. Background technique [0002] Percutaneous coronary intervention (PCI) has become the standard treatment for stenotic coronary artery disease. Drug-eluting balloon (DEB) can deliver and release drugs that inhibit restenosis to the treatment segment of blood vessels, and at the same time The lack of metal implants, which reduces the need for long-term dual antiplatelet therapy (DAPT), has received widespread attention since its birth. However, the incidence of short-term and mid-term restenosis after balloon dilatation and traditional stenting is as high as 5%-60%, which seriously limits the development of PCI. With the in-depth study on the mechanism of restenosis after coronary intervention and the successful development of drug-coated stent (DES), it is possible to prevent restenosis with DES. Even so, [0003] There is st...
