Abstract
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.

1-40. (canceled)
An implant delivery device comprising:
- a shaft;
- an elastically deformable plate attached to a distal portion of the shaft, the deformable plate comprising a first surface and at least one retaining mechanism on the first surface configured to retain a sheet-like implant relative to the deformable plate;
- and
- a deformation mechanism that elastically deforms the deformable plate between an open first configuration and a closed second configuration.
A method of delivering a sheet-like implant to a surgical site, the method comprising:
- obtaining a delivery device and the sheet-like implant positioned on the delivery device, the delivery device including a shaft, an elastically deformable plate attached to a distal end of the shaft, the deformable plate including a first surface and at least one retaining mechanism on the first surface configured to retain the sheet-like implant relative to the deformable plate, the deformable plate having an open first configuration and a closed second configuration, and a deployment mechanism that elastically deforms the deformable plate between the first configuration and the second configuration, wherein the plate includes a perimeter defining at least one notch along the perimeter;
- passing the sheet-like implant and the delivery device, positioned in the second configuration, through a cannula and into the surgical site;
- deploying the sheet-like implant and the delivery device to the first configuration;
- positioning the sheet-like implant in the first configuration against a tissue within the surgical site;
- and
- positioning a surgical fastening tool at and/or adjacent to an area defined by the at least one notch to deliver an anchor or suture to the sheet-like implant and the tissue.
