Ngokweenkcukacha, isixhobo seVivistim, esenziwe yi-MicroTransponder biotechnology, sivuselela i-vagus nerve - i-nerve enkulu ehamba ukusuka entloko nasentanyeni ukuya kwisisu. Isixhobo sifakwe ngelixa isigulane siqhuba ukuqeqeshwa kokuvuselela intshukumo, exelela ingqondo ukuba "ibukele" le ntshukumo.

Uphando olutsha olupapashwe lubonisa ukuba iVivistim iphucula kakhulu ubuthathaka bengalo kunye nokusebenza kweemoto kubantu abanobuthakathaka bexesha elide emva kokuphazamiseka. I-Vagus nerve stimulation (VNS) ihlolwe kwixesha elidlulileyo njengendlela yokunyanga ukudakumba, isithuthwane, i-tinnitus, i-stroke, isifo senhliziyo kunye nokukhuluphala.

utyando lofakelo

Ukuvuselela imithambo-luvo yevagus kubandakanya utyando lokufakelwa, oluthi lufane nolwesincedisintliziyo. Ukufakelwa kufakwe kwizigulane phantsi kwe-anesthesia jikelele ngokwenza i-neck incision incision malunga ne-cricoid cartilage, ejikeleze i-trachea.

Xa sele ifakwe, isixhobo sivuselela i-vagus nerve kwicala lasekhohlo lentamo ngexesha lokuvuselelwa ngokomzimba. Impembelelo yombane evela kwiFifistim isoloko ivakala sisigulana “njengokuntyiloza okwethutyana emqaleni” ethi iphele ngokuhamba kwexesha.

Ihlala iminyaka engamashumi amabini

Ngokutsho kweqela lezenzululwazi, ukhuseleko lwe-VNS implants luye lwaboniswa kwezinye iindawo zeklinikhi, kunye nomphandi uDkt Charles Liu, umlawuli we-USC Neurorestoration Centre eCalifornia, "Ukufakelwa kwe-VNS kuye kwenziwa iminyaka engaphezu kwe-20 kwaye ngokuqhelekileyo ilula kwaye ithe ngqo," ebonisa umdlandla "ngokwenza utyando olukhuselekileyo nolusekwe kakuhle olunokunceda ukubuyisela ukusebenza kwesandla kunye nengalo emva kokuphazamiseka."

Ukulahleka kwexesha elide lomsebenzi wengalo kuqhelekile emva kokubetha - olona hlobo luqhelekileyo lwe-stroke oluhambelana nokuvaleka kwegazi ukuya kwingqondo. Phantse i-80% yabantu abane-stroke ebukhali banobuthathaka bengalo, kwaye ukuya kuthi ga kwi-50 ukuya kwi-60% baseneengxaki eziqhubekayo emva kweenyanga ezintandathu. Okwangoku lumbalwa unyango olusebenzayo lokuphucula ukuchacha kwengalo emva kokuphazamiseka, kwaye unyango olunamandla ngokwangoku lolona khetho lungcono lonyango.
