Pain Points

Cov kws tsim qauv tsim ntsib ntau lub fwj dej thaum siv crimped hypotube rau hauv vascular-intervention catheter-delivery-systems. Kev tsim tsis raug crimp-zone geometric-tsim ua rau muaj kev pheej hmoo: crimp-indent occupies ntau radial qhov chaw ua rau sab nrauv profile ntawm catheters rau tortuous-vascular navigation; tsis tsim nyog crimp-segment ntev txo kev sib koom tes-mechanical-lub zog; crimp-txoj hauj lwm teeb ua puas laser-txiav-hom-enabled yooj-torque-tswj nta ntawm lub hauv paus hypotube. Vascular-intervention scenarios nrog rau percutaneous transluminal coronary angioplasty, peripheral-vascular thiab neurological kev cuam tshuam yuav tsum tau hypotube xws li Ø0.20 mm-20 mm nrog yam tsawg kawg nkaus 0.012 mm kerf dav rau laser-cut-base lug. Kev tsim kho qhov tsis xws luag tsuas yog nthuav tawm tom qab kev tsim qauv tsim, ua rau muaj kev rov ua dua tshiab thiab txuas ntxiv kev kho mob-duab R & D voj voog. Cov neeg tsim qauv kuj tseem yuav tsum sib npaug cov kev xav tau ntawm cov khoom siv, qhov loj me, kev tsim khoom thiab ISO13485-raws li kev xav tau.

Txoj Cai Ua Haujlwm

Crimped hypotube rau vascular-delivery-systems hloov lub zog thawb thiab lub zog los ntawm cov khoom siv-interlock crimp zones ntawm hypotube substrate thiab mating-components. Geometric-design parameters suav nrog crimp-indent kom muaj nuj nqis, indent qhov tob, crimp-axial-length, circumferential-distribution thiab crimp-zone-txoj hauj lwm txheeb ze rau laser-txiav qauv. Crimp-indent qhov tob tswj cov yas-deformation magnitude thiab tuav-force; crimp-axial-length txiav txim qhov zoo-sib cuag-chaw rau mechanical inter-locking. Crimp-zones yuav tsum tsis txhob laser-txiav kerf slots ntawm hybrid-structure hypotube; overlapping crimp-indent thiab laser-txiav slots yuav rhuav tshem cov txheej txheem-kev ncaj ncees thiab degrade kink-tsis kam, torque-hloov kev ua tau zoo. Base hypotube cov ntaub ntawv suav nrog 304,316L stainless hlau, 17-7PH, Nitinol thiab L605 alloy. Cov khoom sib txawv ntawm cov khoom siv sib txawv ntawm cov khoom siv sib txawv tau teeb tsa cov kev txwv siab tshaj plaws rau crimp-geometric-parameters. Lub rooj sib txoos zaum kawg yuav tsum khaws kom txaus lumen-cross-section rau kev qhia-xaim hla thiab xa cov kua dej hauv qab crimp-deformation.
