Baloon dilatation catheter a madung daw gaw balloon rai nna, shi a arung arai ni gaw, shawng nnan na rubber kaw nna, dai ni na polymer arung arai. Ya aten hta, gat lawk hta nga ai madung balloon arung arai ni gaw, polyamide (PA) hte polyethylene terephthalate (PET){1}} Polyamide arung arai ni gaw kaja ai elasticity hte n-gun n-gun hpe ninghkap lu ai atsam nga ai, n-gun atsam hpe n-gun jaw lu ai, n-gun kaba ai aten hta, n-gun ja ai, n-gun rawng ai ni hpe n-gun jaw lu ai. n-gun ja ai n-gun hpe n-gun ja ai n-gun. Polyethylene terhephthalate hpe grai ra sharawng ai aten ni gaw, shi a grai kaja ai n-gun kya ai lam hpe ninghkap lu ai atsam hte chemical stability a majaw ra sharawng ai, hkum hkrang hta aten galu n-gun jaw na matu grau nna htuk manu ai.
Ndai catheter a madung daw hpe polyurethane (PU) shing nrai polyethylene (PE) n-gun dat ni hte galaw da ai. Polyurethane arung arai ni gaw sai lam bunghku de n-gun shayawm ya lu nna, shanhte a grai kaja ai biocompatibility hte elasticity a majaw, hkum hkrang n-gun yawm ai lam hpe shayawm ya lu ai.

Dai hta n-ga, catheter a hkrang shapraw ai lam hpe grau kaja hkra galaw na matu hte X-ray npu na tsi sarawun ni a hkrak ai bungli hpe galaw ya lu na matu, catheter a ntsa hpe barium salts (sh) iodine{1} ngu ai coating hte ka-up da ai.
Lahta na arung arai ni hta n-ga, n-gun ja ai balloon dilatation catheter nkau mi gaw, n-gun rawng ai coating hpaji hpe mung lang mai ai, ga shadawn, tsi mawan hpe n-gun jaw ai lam.
