Case Update Concerning Synthetic Trachea


Director of Public Prosecution Mikael Björk provides a brief case update on the preliminary investigation concerning the two patients, now deceased, who had a synthetic trachea surgically implanted.

On 11 December 2018, Director of Public Prosecution Mikael Björk took the decision to reopen a discontinued preliminary investigation concerning a surgeon previously employed at Karolinska University Hospital. The suspected crime was a gross offence of causing bodily harm. The preliminary investigation is still underway and has taken longer than expected.

During the course of the resumed preliminary investigation, investigative measures have been taken both in Sweden and abroad. About 20 interviews have been carried out and additional interviews of, for example, the suspected surgeon are to be conducted.

“The material in the preliminary investigation is very extensive. The final serving to the surgeon and his public counsel is going to take a long time and therefore this process has already commenced even though not all investigative measures have yet been taken. At the moment, it is too early to say when a decision regarding the charge can be taken since it depends on the result of the remaining investigative measures. Our aim is that a decision can be made during the first quarter of next year,” says Director of Public Prosecutions Mikael Björk.

Director of Public Prosecution Mikael Björk is not available to the media. Any new information will be made public via a press release.
