Gradient Coated Hypotube Rau Asymmetric Interventional Device Performance

Pain Point

Cov txheej txheem laser-txiav hypotubes txais yuav hloov pauv cov qauv txiav kom ua tiav qhov yooj yim gradient: distal kawg yog hloov tau yooj yim rau nkoj navigation, proximal kawg khaws cia siab thawb thiab torque kis tau tus mob. Txheej kev kho mob rau cov pa hypotubes feem ntau siv txheej txheej thoob plaws lub raj ntev. Cov txheej txheej tsis tuaj yeem sib txawv qhov kev xav tau ntawm hypotube proximal thiab distal ntu. Hypotube distal seem xav tau lub lubrication zoo dua thiab biocompatibility rau navigating ilv anatomical cheeb tsam. Proximal seem hais txog kev hnav tsis kam los txhawb nqa rov qab torque input. Ib leeg-formula uniform txheej compromises ib-sab kev ua tau zoo yuav tsum tau. Siv cov txheej tuab kom zoo dua distal lubrication yuav degrade proximal-end mechanical teb; nyias txheej rau proximal-kawg durability tsis ua raws li qhov kev xav tau ntawm qhov kawg ntawm qhov kawg. Cov kws tsim khoom siv kho mob ntsib qhov mob tsis sib haum no. Gradient coated hypotube muab cov kev daws teeb meem los ntawm kev siv cov txheej txheem sib txawv raws li hypotube axial kev taw qhia.

Taw qhia txog Txoj Cai

Gradient coated hypotube realizes axially variable coating property matching hypotube proximal-to-distal functional differentiation. Lub hauv paus hypotube siv laser-txiav qauv (nruam muab kauv txiav, cuam tshuam kauv txiav, radial txiav) los tsim cov hauv paus gradient mechanical kev ua tau zoo. Gradient txheej kho cov khoom siv txheej, thickness los yog txheej ntom ntom raws lub raj ntev. Cov ntu nruab nrab tuaj yeem siv cov txheej txheem siab lubrication; ntu ntu txais cov txheej txheem siab hnav-tiv taus. Hloov chaw ntawm cov txheej txheej sib txawv yog qhov tseeb raws li cov neeg siv khoom 2D / 3D kos duab. Kev tswj nruj nruj tiv thaiv txheej txheej los ntawm kev sau 0.012 hli zoo laser kerfs, yog li thawj laser-txhais tau yooj yim gradient tsis raug rhuav tshem. Nto kho tshuab ua ntej ua kom muaj kev ruaj khov rau cov txheej txheej sib txawv rau cov hlau tsis muaj hlau, Nitinol lossis L605 hypotube substrates. Gradient txheej tsis rewrite hypotube base-structure mechanics; nws superimposes customized deg-kev ua tau zoo faib txuam nrog kev kho mob asymmetric functional xav tau.
