Lisebelisoa tsa bohloeki ba bongaka ke lisebelisoa tse khethehileng tse sebetsang tse sebelisoang lits'ebetsong tsa bongaka le ka ho toba kapa ka tsela e sa tobang le lisele tsa motho. Ka hona, bakeng sa lisebelisoa tsa polymer tsa bohloeki ba bongaka, haholo-holo lisebelisoa tsa polymer tsa bongaka tse kentsoeng, li lokela ho kopana le thepa ea non-toxicity, inertness ea lik'hemik'hale, histocompatibility, ho lumellana ha mali, ho hanyetsa botsofali ba likokoana-hloko, sterilizability, non-carcinogenicity, le boiketlo ba ho sebetsa, ho netefatsa polokeho ya disebediswa tsa mmele wa motho.
Lintho tsa PA li na le sebopeho se ts'oanang sa amide se nang le liprotheine tsa tlhaho tsa 'mele oa motho, li na le biocompatibility e ntle,' me ha ho bonolo ho etsa hore lisele tsa lintho tse phelang li hlahise matšoao a susumetsang.
Ho phaella moo, e na le botsitso bo botle ba lik'hemik'hale le thepa ea mechine e laoloang, joalo-joalo Ka nako e ts'oanang, lisele li ka ba adsorbed holim'a lisebelisoa tsa PA. Thepa ena eohle e ikhethang e etsa hore thepa ea PA ea bongaka le ea bophelo bo botle, haholo-holo thepa ea PA e kentsoeng, e bapala karolo e ntle ho fokotsa bongata, ho fetola thepa ea mochini, haholoholo ho thusa ho theha litlamorao tsa mochini lipakeng tsa thepa ea PA e kentsoeng le 'mele oa motho.
Ka lebaka la matla a eona a matle a mochini, ho hahloa ho hoholo le ho hanyetsa kutu, le biocompatibility e ntle, PA e sebelisoa haholo joalo ka catheter ea bongaka le lisebelisoa tse ling tsa bophelo bo botle.
