Idea origin

Traditional stents remain in the body, thereby potentially causing new problems. These are secondary to physiological responses to the foreign body where one result is the formation of scar tissue with different consequences.

Since stents usually are needed only for a limited time Professor Erney Mattson together with Professor Torbjörn Lundh considered long on how to create a stent that can be removed. A brilliant idea was born one day when a standard sock unravelled. Many years of intensive, creative and brave development has followed this eureka moment.

Idea progression

The product idea has evolved over the last 12 years from blood-vessels to other areas. 

The main reason for redirecting attention from blood-vessels is mainly due to the high cost and extended need for documentation in obtaining medical approval for stents in blood-vessels. 

The versality of the device enables many usage areas for both people and animals not only reducing costs but above all improving the quality of life for those treated.

With this potential for multiple applications the focus going forward is to the segment with the most immediate and significant impact.
