Saskatchewan's Health Minister Don McMorris says his government will announce details this week of how $5 million in provincial funding will be used to help advance clinical trials of the controversial "liberation" procedure to treat multiple sclerosis.

The Saskatchewan Party government's initial plan to fund provincial trials of the potential treatment for the disease suffered a setback in June, when the Saskatchewan Health Research Foundation said the research proposal that it received didn't meet the criteria set out by the foundation's expert panel.

But McMorris said the government has been working to determine how the funding can be used for clinical trials.

The procedure involves angioplasty to open veins in the neck to increase blood flow from the brain and spinal cord. It's based on a theory that links MS with a condition called chronic cerebrospinal venous insufficiency or CCSVI.
