- 11 Flowable graft materials are provided which comprise collagen powder and a liquid in an amount sufficient to impart a flowable consistency to the material. The 5 graft materials are sufficiently formable and pliable so as to provide both superior contact with and easier access to a surgical site than typical, more rigid grafts such as collagen sheets. These flowable materials may also be in a fluidized, paste-like and/or gel-like state and may be moldable and/or ejectable. The flowable collagen materials reduce and/or eliminate post implantation problems associated with other 10 materials, e.g. synthetic dural sealants (hemostasis products), such as product swelling after application and implantation. The flowable graft materials are particularly useful as a dural graft. 20/04/09,va 17887 speci, II |
