Abstract

En implanterbar vasookklusiv anordning er vist. Den er vanligvis en vasookklusiv spiral (100) som omfaner en primær helisk viklet spiral (102) som deretter kan vikles til en sekundær form. Sentralt for oppfinnelsen er bruken av et strekkmotstandig element (108) som går gjennom det dannede hulrom, hvilket strekkmotstandige element (108) er fast innfestet, direkte eller indirekte, til spiralen (102) på minst to steder. Det strekkmotstandige element (108) ligger fortrinnsvis noe løst inne i huirommet for slik å hindre spiralen i å klappe sammen, binde og avstiver derfor under foringen av vindingene gjennom menneskekroppen. Spiralen bor bøye lett. I enkelte varianter av oppfinnelsen kan det strekkmotstandige element (108) være utformet som spiraltupper i endene av spiralen ved bruk av enkelt utstyr slik som loddemetall eller lignende. Tuppene er vanligvis av samme diameter som selve spiralen. Dette strekkmotstandige element (108) har som hovedformål å hindre strekking av spiralen under bevegelse av spiralen, dvs. ved tilbakehenting eller omplassering etter anbringelse.
