Polymer Jacketed Hypotube Rau Catheter Delivery System Rwb thaiv tsev tiv thaiv

Pain Point

Laser-cut hypotubes ua hauj lwm ua torque- kis tau tus mob Cheebtsam rau minimally invasive interventional xa systems. Base hlau hypotubes nrog rau cov hlau tsis muaj steel 304,316L thiab Nitinol xa zoo heev pushability, trackability, torque hloov thiab kink kuj. Ntau yam laser txiav geometries xws li nruam muab kauv txiav thiab cuam tshuam kauv txiav tso cai rau engineers los kho qhov yooj yim-rau-distal yooj rau PTCA, peripheral vascular thiab neurological txheej txheem. Txawm li cas los xij, liab qab laser-txiav hlau hypotube coj cov teeb pom kev zoo. Tshem tawm cov hlau thiab cov npoo ntse ntse (tsawg kawg 0.012 hli kerf dav) tuaj yeem rhuav tshem cov kab catheter uas nyob ib sab thaum lub sij hawm cyclic torque thiab khoov txav. Hauv electrophysiology thiab imaging-assisted intervention devices, exposed metal hypotube tsim hluav taws xob cuam tshuam. Uninsulated hlau substrates kuj muaj kev sib cuag ncaj qha nrog lub cev kua, tsa kev txhawj xeeb txog galvanic corrosion thiab cov ntaub so ntswg hauv zos. Nto polishing thiab ib txheej txheej txheej ua haujlwm tuaj yeem txo qhov kev sib txhuam, tab sis cov txheej nyias nyias tsis tuaj yeem muab kev sib cais ntawm lub cev zoo rau cov txheej txheem nyuaj. Cov kws tsim khoom siv kho mob ntsib kev lag luam tsis tu ncua: khaws cov khoom siv kho tshuab tunable ntawm laser-machined hypotube thaum ntxiv kev sib cais ntawm lub cev thiab hluav taws xob. Polymer jacketed hypotube tshwm sim los daws qhov teeb meem kev mob ntev ntev.

Txoj Cai Taw Qhia

Polymer jacketed hypotube integrates ib tug precision laser-txiav hlau hypotube substrate thiab nruam extruded los yog tshav kub-shrink polymer txheej tsho. Lub hauv paus hypotube khaws tag nrho cov yam ntxwv ntawm cov cuab yeej qub uas tau hais tseg los ntawm cov qauv laser txiav: gradient hloov tau los ntawm qhov kawg ntawm qhov kawg mus rau qhov kawg, lub zog quab yuam, kev sib kis ntawm lub zog thiab kev ua haujlwm tsis zoo yog khaws cia. Lub tsho polymer tsim ib qho seamless txheej barrier npog lub raj sab nraud txoj kab uas hla thiab bridging hla laser-txiav slots.
