Abstract
A method of reducing adhesion at a site of trauma includes forming a film from an alginate solution, contacting the film with a cross-linking solution to form a cross-linked mechanically stable sheet, and placing at least a portion of the sheet at the site of trauma. An anti-adhesion barrier includes a sheet of ionically cross-linked alginate having a thickness in a range of 0.25 mm to 10 mm. The sheet has a tear strength sufficient for suturing and repositioning. A drug delivery device includes a cross-linked alginate container that can be filled with a drug.
