I-PTA (Percutaneous Transluminal Angioplasty) I-Balloon Catheter iyisisetshenziswa sezokwelapha esingenele kancane esisetshenziselwa ukwelapha imithambo yegazi emincane noma evalekile. Isetshenziswa ngokuyinhloko ezinqubweni ze-angioplasty ukubuyisela ukugeleza kwegazi ngokunweba i-lumen yomkhumbi. I-catheter inebhaluni eliphefumula phezulu phezulu, elinwebeka ukuze licindezele ama-plaque noma izilonda odongeni lomkhumbi, ngaleyo ndlela lithuthukise ukugeleza kwegazi.

I-PTCA Balloon Catheter isetshenziselwa kakhulu ukwelapha isifo senhliziyo (njenge-angina pectoris, i-myocardial infarction, njll.), ngokunweba imithambo yenhliziyo emincane noma evalekile ngebhaluni, kuthuthukiswe ukutholakala kwegazi le-myocardial. Kuyithuluzi elibalulekile ku-cardiology yokungenelela futhi lisetshenziswa kabanzi emakamelweni e-cardiac catheterization.
