Problems solved by technology

However, since the sheath can slide relative to the pushing catheter along the axial direction of the pushing catheter, and the pushing catheter is made of a flexible material, during the process of withdrawing the sheath, that is, when the sheath slides toward the proximal end of the pushing catheter, The push catheter is easy to bend, which affects the smooth withdrawal of the sheath

Embodiment Construction

[0041] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings. Apparently, the described embodiments are only some, not all, embodiments of the present invention. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0042] First of all, it needs to be explained that in the field of interventional medicine, the end of the instrument close to the operator is usually called the proximal end (ie, the operating end), and the end of the instrument away from the operator is called the distal end (ie, the insertion end). Specifically, the distal end refers to the end of the instrument that can be freely insert...

Abstract

The invention discloses an anti-bend medicine-coated balloon catheter which comprises a push catheter, a medicine-coated balloon, a protective jacket and a slide mechanism. The medicine-coated balloonis fixed to a distal end of the push catheter, the slide mechanism is connected to the protective jacket and comprises a support component and a slide component, the support component sleeves the push catheter, and the slide component is arranged between the protective jacket and the support component in a connected manner, and can axially slide along the push catheter by the aid of the support component, so that the medicine-coated balloon can be accommodated in the protective jacket or can be exposed out of the protective jacket. The anti-bend medicine-coated balloon catheter has the advantages that the medicine loss ratio of the anti-bend medicine-coated balloon catheter can be reduced in transportation procedures, and the push catheter can be prevented from being bent.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anti-bending drug-coated balloon catheter. Background technique [0002] Arterial stenosis has always been a kind of disease that plagues human beings. In order to cure this kind of disease, human beings have successively experienced treatment stages such as bare balloon, bare stent, and drug-eluting stent. However, the aforementioned treatment options have different defects. Drug-coated balloon catheters emerged as the times require. It not only establishes a channel for blood circulation through balloon expansion, but also the drugs loaded on the balloon can effectively inhibit the proliferation of smooth muscle cells and prevent vascular restenosis. [0003] In traditional drug-coated balloon catheters, the active drug coating on the surface of the drug-coated balloon is exposed in the vascular environment before the drug-coated balloon is inflated, which is easily ...
