Aninit long bekgraun bilong wok bilong kamapim ol nupela medikel teknoloji i go het yet, ol kateta bilong balun dilatesen i kamap wanpela tul i no inap pinis long vaskula intavensenel operesen. Pasin bilong makim ol samting bilong en i stret wantaim sefti, durability na wok bilong kateta, na i mekim bikpela wok long kamap gut o feil bilong operesen{1}}
Bikpela hap bilong kateta bilong balun dilatesen em balun, na ol samting bilong en i bin kamap long namba wan raba i go long ol polima samting bilong nau. Long nau, ol bikpela balun samting long maket em poliamide (PA) na polietilen teeptalet (PET) na ol i gutpela long lukautim ol samting i stap gut taim ol i sanap strong na ol i no inap long stap gut, na ol i no inap long lukautim gut ol samting i stap gut taim ol i no inap long stap gut, na ol i no inap long lukautim gut ol samting bilong lukautim ol samting i stap gut. ol taim we i nidim bikpela strong bilong tensil. Polyethiline tereptalet i laikim tru long gutpela les resistens na kemikel stebiliti bilong en, na em i gutpela tru long putim longpela taim insait long bodi.
The main part of the catheter is usually made of polyurethane (PU) or polyethylene (PE) materials. Polyurethane materials can reduce irritation to the blood vessel wall and reduce surgical risks due to their excellent biocompatibility and elasticity. Polyethylene can adapt to complex vascular pathways with its good flexibility and ductility.
Antap long dispela, bilong mekim gut wok bilong lukluk long kateta na helpim ol dokta aninit long X-rei, pes bilong kateta i save karamapim wantaim wanpela kot i gat ol sol bilong barium o aiodine. Dispela koting i no helpim tasol long luksave long visibiliti bilong kateta, tasol em i strongim tu baiosefti bilong em i stap laip.
Antap long ol samting antap, sampela hai-end balun dilatesen kateta i ken yusim tu komposet koting teknoloji, olsem marasin koting. Dispela kain kot i ken putim stret ol marasin long dispela sua taim balun i go bikpela, na em i winim tupela samting i kamap long tritim na stopim vascular restenosis bilong ol vaskula.
Long sot toktok, ol samting bilong makim ol samting bilong balun dilatesen em i as bilong ol gutpela tingting i kam long planti samting. Em i no afektim tasol sefti na wok bilong operesen, tasol em i makim tu edvans level bilong medikel teknoloji.
