Better quality of life for stoma patients

Ostomycure has created a new implant that makes everyday living easier for many stoma patients. Swerea has played an important role in the development of the implant, which is made using 3D printing technology.

A new implant that will replace a conventional stoma implant has been developed. Normally, a colostomy pouch is affixed to the stomach with an adhesive, but this can give rise to irritation, odour and sounds. 

The implant becomes part of the body

Instead, the new titanium tube is surgically implanted in the abdomen and grows together with the intestine and soft tissue. The implant becomes an extension of the intestine and is sealed with a plate on the outside of the abdomen.

Professor Ulf Gunnarsson of Umeå University helped Ostomycure to develop the new implant.
“The idea is to make it easier for these patients to use the toilet,” explains Ulf Gunnarsson.

Manufactured with 3D technology

The implant is made using 3D technology, which simplifies the manufacturing process and results in a better product, compared to conventional manufacturing.

“In 3D printing we use a metal powder that melts when we shoot a laser at it. The product is built up layer-bylayer,” says Mats Cardell, Ostomycure.

High demands on the material

The product normally consists of three parts that are welded together. With additive manufacturing, the product can instead be made in a single stage. Ostomycure collaborated with Swerea on the development of the implant.

“Swerea assisted with strength measurements, checked the porosity of the material to see how solid it is and analysed the material composition. The material must be clean and free of contaminants,” explains Mats Cardell.

The new implant has been tested in clinical trials and will soon be introduced on the market.
