Elise Sørensen partnered with Aage Louis-Hansen and his wife Johanne Louis-Hansen, who ran a plastic production factory. This was a turning point as Louis-Hansen saw the great potential of Sørensen's colostomy bag idea.

Aage Louis-Hansen, recognizing the potential of Sørensen's invention, founded Coloplast specifically to manufacture and market the colostomy bag. Coloplast quickly became a leading provider of ostomy care products, revolutionizing the lives of people with colostomies worldwide.

Coloplast's colostomy bag, based on Sørensen's design, gained widespread acceptance and significantly improved the quality of life for individuals undergoing colostomy surgery. Her invention minimized the discomfort, embarrassment, and inconvenience associated with the procedure.
