Brain surgery without stitches

February 3rd, 2010

(PhysOrg.com) -- A breakthrough technology to seal surgical wounds without stitches will be developed for use in delicate brain surgery thanks to a major federal government grant.

A team led by Associate Professor John Foster of the UNSW Bio/Polymer Research Group (BRG) and Professor Marcus Stoodley, a neurosurgeon from Macquarie University, has been awarded a $213,000 development grant from the National Health and Medical Research Council.

Professor Foster's team is investigating potential applications of the world's first thin-film surgical adhesive that uses a unique combination of laser technology and biomaterials. Known as SurgiLux®, it is a natural, strong, flexible film that is compatible with living tissue and is based on the US Food and Drug Administration-approved chitosan, a biomaterial derived from crustacean shells. The film is simply placed over a wound or surgical incision and activated with a conventional infra-red clinical laser to effect closure.

Currently, wound closure in the cranium relies on sutures or "stitches", which can lead to infections and other medical complications.

"The application of SurgiLux® technology will both close and seal these wounds quickly and easily, with significant health and economic benefits," said the Parliamentary Secretary for Health, Mr Mark Butler, announcing the grant.
