Pain Point

Nyob rau hauv qhov kev tshawb nrhiav rau "zoo meej" qhia hlau, engineers tau nce paub tias ib qho khoom siv tsis tuaj yeem ua tau raws li txhua qhov kev xav tau ntawm cov txheej txheem niaj hnub no. Stainless hlau muaj qhov sib txawv torque tab sis kinks yooj yim. Nitinol muab kev yooj yim heev thiab kink tsis kam tab sis tuaj yeem hnov ​​​​"mob" thiab tsis muaj lub zog columnar rau hnyav khoom xa tuaj. L605 cobalt-chromium yog qhov muaj zog heev tab sis nyuaj rau kev ua haujlwm thiab kim heev . 17-7PH nag lossis daus- cov hlau tsis muaj zog muaj lub caij nplooj ntoos hlav zoo heev tab sis tuaj yeem nkig. Qhov mob taw tes yog "kev sib haum xeeb ntxiab": xaiv ib yam khoom txhais tau tias kev txi kev ua tau zoo hauv lwm qhov chaw tseem ceeb. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem nyuaj xws li mob tag nrho occlusions (CTOs), qhov twg cov hlau yuav tsum nruj txaus kom nkag mus rau qhov mob calcified tsis tau hloov pauv txaus los taug qab cov nkoj ua ntej -bent collateral. Kev lag luam xav tau ib txoj hauv kev los sib txuas cov khoom zoo tshaj plaws ntawm ntau cov ntaub ntawv rau hauv ib qho, sib koom ua ke cov tub ntxhais hlau, tsis tsim cov ntsiab lus tsis muaj zog lossis tsis ua haujlwm ntawm cov khoom sib txuas.

Txoj Cai

Lub hybrid tub ntxhais hlau ua haujlwm ntawm lub hauv paus ntsiab lus ntawm "txhua yam kev sib txuas," sib txuas cov ntaub ntawv sib txawv raws li qhov ntev ntawm cov hlau los tsim qhov "zoo tshaj- ntawm-tag nrho- ntiaj teb" kev ua haujlwm profile. Qhov no yog ua tiav los ntawm kev koom nrog cov seem ntawm cov alloys sib txawv-piv txwv li, 304V stainless hlau proximal ntu rau torque, Nitinol nruab nrab - ntu rau kev taug qab, thiab L605 ntu ntu rau kev thawb hnyav. Qhov teeb meem tseem ceeb yog kev hloov pauv ntawm cov ntaub ntawv no. Lub pob tw yooj yim-weld tsim kom muaj kev ntxhov siab uas tuaj yeem ua rau qaug zog tawg. Cov txheej txheem tsim khoom siab tshaj plaws, xws li kos- kev sib txuas, kev sib tw, lossis kev siv laser-txiav hypotube "bridges," yog ua haujlwm los tsim kom muaj kev sib hloov, maj mam hloov. Piv txwv li, ib ntu luv ntawm laser- txiav 316L hypotube nrog cov qauv cuam tshuam rau Kauv tuaj yeem muab tso rau ntawm qhov sib txuas ntawm cov hlau tsis muaj steel thiab Nitinol core. Cov kauv txiav tso cai rau tus choj kom flex, nqus cov kev ntxhov siab los ntawm qhov sib txawv moduli ntawm ob cov ntaub ntawv. Qhov no tsim ib tug nruam, seamless core xaim uas leverages cov yam ntxwv ntawm txhua yam khoom raws nraim qhov lawv xav tau tshaj plaws.

Kev faib khoom siv

• SS -Nitinol Hybrid: A 304V lossis 316L stainless hlau proximal core rau torque, koom nrog Nitinol distal core rau yoog raws thiab kink tsis kam. Lub workhorse rau complex coronary thiab peripheral interventions.
• Nitinol{0}}L605 Hybrid: Nitinol proximal thiab nruab nrab -core rau trackability, nrog rau L605 distal core rau lub zog thawb hnyav hauv CTO kev cuam tshuam.
• 17-7PH-316L Hybrid: Ib tug 17-7PH proximal core rau nws zoo heev caij nplooj ntoos hlav zog thiab thawb, hloov mus rau ib tug 316L distal core rau enhanced corrosion kuj thiab yooj.
• Tri-Material Core: Ib qho kev tsim qauv zoo nkauj uas muaj qhov tsis sib xws ntawm cov hlau tsis sib xws, Nitinol nruab nrab -section, thiab radiopaque platinum-iridium lossis kub distal tip rau txhim kho pom kev nyob rau hauv fluoroscopy.
• Hypotube-Bridged Hybrid: Ib tug hybrid core qhov twg cov khoom hloov pauv tau ntxiv nrog lub laser -txiav ntu hypotube (piv txwv li, 316L lossis 17-7PH) uas ua raws li tus choj hloov tau yooj yim, kev ntxhov siab-absorbing.

Phau Ntawv Qhia

• Daim ntawv qhia kev ua haujlwm: Qhia meej meej cov yam ntxwv ua tau zoo (torque, laub, yoog raws, kink tsis kam) rau txhua cheeb tsam anatomical ntawm cov txheej txheem.
• Kev xaiv khoom: Xaiv cov khoom zoo rau txhua cheeb tsam. Piv txwv li, siv cov hlau tsis muaj steel rau thaj tsam ze ntawm lub zog, Nitinol rau nruab nrab - thaj chaw taug qab, thiab L605 rau thaj tsam cuam tshuam.
• Hloov Tsim: Zam kev hloov pauv sai sai. Siv ib daim kab xev sib tsoo rau ntawm ntu stainless hlau thiab lub laser-txiav tus choj hypotube los tsim kom muaj kev sib hloov, maj mam hloov hauv qhov tawv.
• Kev koom ua ke: Siv cov txheej txheem sib koom ua ke, xws li laser vuam lossis swaging, kom ntseeg tau tias muaj zog, qaug zog- tiv thaiv kev sib txuas ntawm cov khoom sib txawv.
• Kev Ntsuas Kev Nyuaj Siab: Ua nruj nreem kev soj ntsuam kev qaug zog ntawm cov tub ntxhais hybrid, nrog rau kev tsom mus rau cov khoom siv hloov chaw. Cov hlau yuav tsum raug rau ntau lab ntawm kev khoov mus rau hauv qhov chaw simulated vascular.
• Khoom Muag Khoom Zoo: Xyuas kom cov chaw tsim khoom muaj kev tswj xyuas zoo (ISO 13485) thiab tuaj yeem muab tag nrho traceability rau tag nrho cov ntaub ntawv siv hauv hybrid core.

Tiag -Kev Paub Txog Ntiaj Teb

Ib pab neeg tsim cov ntawv qhia xov hlau rau kev kho mob ntawm CTOs tau ntsib qhov kev sib tw tseem ceeb. Cov hlau yuav tsum tau nruj txaus kom nkag mus rau qhov chaw calcified, tsis tau hloov pauv txaus los mus rau lub nkoj ua ntej -bent collateral. Lawv qhov kev tsim thawj zaug tau siv lub zog 17-7PH core, uas muab lub zog tsim nyog tab sis yog nruj heev thiab kinked yooj yim hauv lub cev tortuous. Qhov kev daws teeb meem yog hybrid core tsim. Lub zeem muag 150 cm yog lub zog 304V stainless hlau core rau torque. Tom ntej no 30 cm yog Nitinol ntu rau kev taug qab. Qhov kawg 10 cm yog ntu L605 rau kev thawb hnyav. Txhawm rau kom muaj kev hloov pauv ntawm cov ntaub ntawv, 5 cm ntu ntawm laser - txiav 316L hypotube nrog tus qauv cuam tshuam Kauv tau muab tso rau ntawm txhua qhov sib txuas. Qhov tshwm sim yog ib tug hlau uas yuav raug thawb los ntawm ib tug calcified lesion nrog lub zog ntawm ib tug khoom hlau, tsis tau yuav navigate lub feem ntau tortuous anatomy nrog kev hlub ntawm ib tug micro-catheter. Qhov kev sim tshuaj ntsuam xyuas tau pom tias muaj kev txhim kho tseem ceeb hauv kev ua tiav thiab txo cov teeb meem.

Lub hybrid tub ntxhais hlau yog qhov kawg qhia ntawm lub tshuab - engineering mus kom ze rau kev kho mob tsim. Nws lees paub tias tsis muaj ib qho khoom siv zoo meej thiab qhov kev daws teeb meem zoo tshaj plaws feem ntau yog kev sib txuas ntawm ntau cov ntaub ntawv, txhua tus xaiv rau nws cov khoom tshwj xeeb. Los ntawm seamlessly integrating sib txawv alloys thiab siv advanced manufacturing cov tswv yim zoo li laser txiav los tswj cov kev hloov, engineers muaj peev xwm tsim ib tug tub ntxhais hlau uas muaj ntau tshaj li cov sum ntawm nws qhov chaw. Lub hybrid tub ntxhais hlau tsis yog tsuas yog kev sib haum xeeb; nws yog ib tug tshiab paradigm nyob rau hauv interventional tshuaj.

Outlook & Cov Lus Pom Zoo

Lub neej yav tom ntej ntawm hybrid cores nyob rau hauv txoj kev loj hlob ntawm txawm ntau sophisticated cov khoom ua ke thiab kev hloov technologies. Peb yuav pom qhov tshwm sim ntawm "active" hybrid cores nrog embedded sensors thiab actuators uas tuaj yeem hloov kho qhov nruj ntawm qhov sib txawv ntawm cov hlau. Kev lag luam yuav tsum tau tsom mus rau kev tsim cov khoom siv tshiab, biocompatible adhesives thiab koom nrog cov txheej txheem uas tuaj yeem tsim kom muaj zog dua thiab txhim khu kev qha. Cov neeg tsim khoom yuav tsum nqis peev hauv kev tshawb fawb kom nkag siab ntxiv txog kev sib cuam tshuam ntawm cov ntaub ntawv sib txawv hauv cov tub ntxhais sib xyaw, ua kom muaj kev tsim cov cuab yeej siv tau zoo dua thiab siv tau zoo.
