Surgical delivery devices of the invention have a delivery shaft extending from a handle, with a deformable member such as a plate or a leaf at a distal portion of the shaft with a surface carrying an implant for orthopedic surgery. A trigger or lever on the device positions the deformable member between a first cylindrical configuration that can pass through a cannula used in arthroscopic surgery and a second, substantially flat configuration useful to place the implant on tissue during the arthroscopic surgery. Preferably the trigger may be operated to hold the deformable plate or leaf in any of a continuum of positions between the first cylindrical configuration and the second, substantially flat configuration.
