I-PTA (i-Percutaneous Transluminal Angioplasty) I-Balloon Catheter iyithuluzi lezokwelapha elingangenisi kakhulu elisetshenziselwa ukwelapha imithambo yegazi emincane noma evalekile. Isetshenziswa kakhulu ezinqubweni ze-angioplasty ukubuyisela ukugeleza kwegazi ngokwandisa i-lumen yemithambo. I-catheter inebhaluni elifuthwayo esicongweni sayo, elikhula ukuze licindezele i-plaque noma izilonda odongeni lwemithambo yegazi, ngaleyo ndlela kuthuthukiswe ukugeleza kwegazi.

I-PTCA Balloon Catheter Isetshenziswa kakhulu ekwelapheni isifo senhliziyo (njenge-angina pectoris, i-myocardial infarction, njll.), ngokwandisa imithambo yenhliziyo evalekile noma evalekile ngebhaluni, ukuthuthukisa ukutholakala kwegazi lenhliziyo. Iyithuluzi elibalulekile kwezokwelapha inhliziyo futhi lisetshenziswa kabanzi emakamelweni okufaka i-catheter yenhliziyo.
