Title:
ANTI-BEND DRUG-COATED BALLOON CATHETER
Document Type and Number:
WIPO Patent Application WO/2020/038024
Kind Code:
A1
Abstract:
An anti-bend drug-coated balloon catheter (100), comprising a pushing catheter (20) and a drug-coated balloon (30) fixed to a distal end of the pushing catheter (20). The drug-coated balloon catheter (100) further comprises a sheath (40) and a sliding mechanism (50) connected to the sheath (40); the sliding mechanism (50) comprises a support member (51) sleeved outside the pushing catheter (20) and a sliding member (52) between the sheath (40) and the support member (51); the sliding member (52) slides in the axial direction of the pushing catheter (20) by means of the support member (51), so that the drug-coated balloon (30) is housed in the sheath (40) or exposed outside the sheath (40). During the conveying process of the anti-bend drug-coated balloon catheter (100), not only can the drug loss rate be reduced, but also the pushing catheter (20) can be prevented from being bent.
