  • Publication number: 20170224344
    Abstract: The present invention relates to a sutureless method of repairing soft tissue defects in soft tissue including ligaments such as anterior cruciate ligaments (ACLs). In particular, the present invention relates a sutureless method of repairing soft tissue defect comprising: (i) providing a collagen-containing patch adapted to enclose at least a portion of said soft tissue defect; (ii) contacting said soft tissue defect and/or collagen-containing patch with a sensitizer; (Hi) enclosing said soft tissue defect in said collagen-containing patch to produce a bioactive chamber; and (iv) adhering said collagen-containing patch to said soft tissue defect without sutures.

  • Publication number: 20170216014
    Abstract: There is disclosed a collagen construct comprising a plurality of elongate strips, wherein each strip contains a plurality of collagen fibres that are substantially aligned along the length of the respective strips, and the strips are braided or woven together to produce a collagen construct in the form of a rope that can be used for replacing tendons or ligaments, such as cruciate ligaments. Also disclosed is a method for making or producing the collagen construct from a collagen membrane having a plurality of collagen fibres being substantially aligned parallel to each other in a common direction. The membrane is cut along cut lines that are orientated substantially parallel to that common direction, thereby to separate elongate strips from the membrane. The strips are then braided or woven together to form the collagen construct.

  • Publication number: 20160361468
    Abstract: The present invention relates to methods for preparing bioscaffolds useful in the repair of tears. More specifically, the invention relates to a method of treating rotator cuff tear in a mammalian subject in need thereof comprising the steps of: (i) selectively expanding tenocytes in vitro in culture medium comprising insulin or a functional derivative and a glucocorticoid or a glucocorticoid-like molecule to produce a culture of expanded tenocytes; (ii) seeding a bioscaffold with said expanded tenocytes to produce a tenocyte seeded bioscaffold; and (iii) implanting said tenocyte seeded bioscaffold proximal to the rotator cuff tear. The present invention also relates to a bioscaffold comprising cells, wherein more than 80% of said cells are tenocytes.
