Micro catheter maka ọrịa obi

Isi ojiji

A na-ezubere iji micro catheter maka ntinye nke mgbasa ozi dị iche, ọgwụ ma ọ bụ ihe embolic n'ime vasculatures akwara, nke zubere maka inye nkwado na ntinye nke wires nduzi ma ọ bụ mgbanwe waya nduzi.

Ọdịdị ngwaahịa

Micro catheter nwere oghere tube, chebe n'ọbọ, ahụ catheter, mgbanaka na-emepe emepe, nke ngwugwu bụ obere akpa rọba akwụkwọ, yana EO mebere ya. Ihe ndị a bụ Pebax, Eurelon, 304V igwe anaghị agba nchara, mkpuchi PTFE, Platinoiridium, TPU, PC, Platinoiridium, mkpuchi Hydrophilic.

Oke ngwa

A na-eji ngwaahịa a igbanye ndị na-achọpụta ọrịa (dị ka ihe dị iche), ndị na-ahụ maka ọgwụgwọ (dị ka nkwadebe ọgwụ, ihe embolic), na ịkwado nduzi nduzi kwesịrị ekwesị n'ime vasculature dị n'akụkụ.

Njirimara

1.Excellent radiopaque, mechiri emechi-loop platinum/iridum marker band agbakwunyere maka ezigbo mgbanwe
2.PTFE n'ime oyi akwa e mere iji nye nnukwu pushability mgbe ọ na-akwado maka ọganihu ngwaọrụ
3.Higher njupụta igwe anaghị agba nchara braid Ọdịdị ofụri catheter aro, na-enye enwekwukwa tensile ike maka ụba crossability.
4.Hydrophilic mkpuchi na ogologo taper imewe si proximal ruo distal: 2.8 Fr ~ 3.0 Fr maka warara ọnya crossability
