Cov kab mob Neurovascular tuaj yeem ua rau muaj kev phom sij rau lub neej thiab tuaj yeem ua rau lub hlwb puas tsuaj mus tas li lossis txha caj qaum. Microcatheters tau siv ntau dua los kho cov kab mob no vim tias lawv muaj kev cuam tshuam tsawg kawg nkaus. Microcatheters yog tshwj xeeb tshaj yog pab tau nyob rau hauv navigating nqaim thiab winding txoj kev ntawm neurovascular system. Nyob rau hauv cov ntsiab lus no, peb yuav tham txog cov qauv tsim uas ua rau neurovascular microcatheters zoo hauv kev kho cov kab mob neurovascular.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm neurovascular micro catheters yog lawv txoj kab me me. Cov catheters no feem ntau tsuas yog ob peb millimeters ntawm txoj kab uas hla, uas ua rau lawv zoo tagnrho rau kev mus txog cov hlab ntsha me me hauv lub hlwb lossis qaum qaum. Qhov me me ntawm cov catheters no tseem tso cai rau lawv taug kev los ntawm qhov chaw nruj yam tsis muaj kev puas tsuaj rau cov ntaub so ntswg.
Lwm qhov tseem ceeb tsim feature ntawm neurovascular microcatheters yog lawv qhov yooj. Cov catheters no yog tsim los ua kom maneuverable, uas tso cai rau cov kws kho mob coj lawv mus rau txoj kev nyuaj neurovascular txoj kev yooj yim. Qhov kev hloov pauv no tseem yuav pab txo qis kev raug mob rau cov ntaub so ntswg ib puag ncig, uas yog qhov tseem ceeb tshwj xeeb hauv cov txheej txheem ilv neurovascular.
Neurovascular microcatheters kuj muaj cov khoom siv siab heev uas ua rau lawv muaj zog thiab ruaj khov. Ntau cov catheters no yog tsim los ntawm cov ntaub ntawv xws li nitinol, uas muaj lub cim xeeb zoo heev thiab tuaj yeem tiv taus qhov kev ntxhov siab ntawm kev taug kev los ntawm txoj kev nruj, winding. Lwm cov ntaub ntawv siv nyob rau hauv neurovascular microcatheters suav nrog polytetrafluoroethylene (PTFE) thiab nylon, uas yog ob qho tib si biocompatible thiab tuaj yeem tiv thaiv qhov tsis xav tau hauv lub cev.
Ntxiv rau lawv cov qauv tsim lub cev, neurovascular micro catheters kuj suav nrog cov thev naus laus zis uas ua rau lawv muaj txiaj ntsig zoo hauv kev kho cov kab mob neurovascular. Cov thev naus laus zis no suav nrog microelectromechanical systems (MEMS) thiab microfluidics. MEMS thev naus laus zis tso cai rau kev tsim cov micro-scale sensors thiab actuators uas tuaj yeem muab tso rau hauv lub taub hau catheter. Cov thev naus laus zis no tso cai rau cov kws kho mob saib xyuas cov ntshav ntws thiab siab hauv lub sijhawm tiag tiag, uas tuaj yeem yog qhov tseem ceeb hauv kev txiav txim siab ua tiav ntawm cov txheej txheem neurovascular.
Microfluidic thev naus laus zis kuj tseem tuaj yeem muab tso rau hauv neurovascular microcatheters kom xa cov tshuaj kho mob ncaj qha mus rau qhov chaw ntawm tus kab mob. Cov kab microfluidic no tuaj yeem siv los xa cov tshuaj, nanoparticles, lossis lwm yam kev kho mob ncaj qha mus rau cov ntaub so ntswg. Qhov kev xa tawm hauv cheeb tsam no tuaj yeem ua rau muaj txiaj ntsig zoo ntawm kev kho mob thaum txo qis cov kev mob tshwm sim.
Thaum kawg, neurovascular microcatheters muaj cov kev yees duab siab tshaj plaws uas tso cai rau cov kws kho mob kom pom cov kab mob neurovascular hauv lub sijhawm. Cov duab technologies muaj xws li magnetic resonance imaging (MRI) thiab xam tomography (CT). Siv cov kev yees duab no, cov kws kho mob tuaj yeem tsim cov duab qhia ntxaws ntxaws ntawm cov kab mob neurovascular thiab coj lub microcatheter mus rau qhov chaw ntawm tus kab mob nrog qhov tseeb.
Hauv kev xaus, neurovascular microcatheters yog cov cuab yeej tseem ceeb hauv kev kho cov kab mob neurovascular. Lawv qhov me me, yoog raws, cov khoom siv siab heev, thiab cov thev naus laus zis ua rau cov catheters zoo heev hauv kev kho cov mob neurovascular nyuaj. Los ntawm kev koom ua ke cov duab zoo tshaj plaws thiab cov thev naus laus zis kho mob, neurovascular microcatheters muab cov kws kho mob tswj hwm kev kho mob ntawm cov kab mob neurovascular. Raws li kev tshawb fawb txog cov ntaub ntawv tshiab thiab thev naus laus zis txuas ntxiv mus, cov catheters yuav ua tau zoo dua hauv kev kho ntau yam ntawm cov kab mob neurovascular.
