In addition, the implant holding portion may be configured to receive the implant with a fixed implant supporting flange member configured to support the implant on one side, and a movable implant supporting flange member. The movable implant supporting flange member may be configured to be slidable between a distal position and a proximal position, wherein, in the distal position, the movable implant supporting flange member and secures the implant against the fixed implant supporting flange member, and in the proximal position, the movable implant supporting flange member is withdrawn from the distal end of the implant delivery device, thus enabling release of the implant. ## Claims ### Claim 1 An implant delivery device, comprising: a handle disposed at a proximal end of the implant delivery device and configured to be grasped by a user; and an outer shaft extending from the handle to a distal end of the implant delivery device; the implant delivery device including an implant holding portion proximate the distal end of the implant delivery device, the implant holding portion being configured to retain a sheet-like implant during implantation of the implant; and the implant holding portion being configured to receive the implant between a fixed implant supporting flange member associated with the outer shaft and configured to support the implant on one side, and a movable implant supporting flange member; wherein the movable implant supporting flange member is configured to be slidable between a first, distal position and a second, proximal position; wherein, in the first, distal position, the movable implant supporting flange member secures the implant against the fixed implant supporting flange member, thus holding the implant in an unfurled configuration; and wherein, in the second, proximal position, the movable implant supporting flange member is withdrawn from the distal end of the implant delivery device, thus enabling release of the implant. ### Claim 2 (depends on 1) The implant delivery device of claim 1, wherein the fixed implant supporting flange member and the movable implant supporting flange member are flexible and resilient such that the fixed implant supporting flange member and the movable implant supporting flange member may be collapsed upon delivery through a cannula. ### Claim 3 (depends on 1) The implant delivery device of claim 1, further including a cannula sealing member disposed about a midportion of the outer shaft. ### Claim 4 (depends on 3) The implant delivery device of claim 3, wherein the outer shaft includes a ring disposed distal to the cannula sealing member and configured to pull the cannula sealing member out of the cannula when the handle of the implant delivery device is pulled in a proximal direction. ### Claim 5 (depends on 1) The implant delivery device of claim 1, wherein the handle includes a slider member configured to be moved in the proximal and distal directions in order to slide the movable implant supporting flange member between the first position and the second position. ### Claim 6 (depends on 5) The implant delivery device of claim 5, further including an inner shaft extending through the outer shaft and connecting the slider member in the handle to the movable implant supporting flange member at the distal end of the implant delivery device. ### Claim 7 (depends on 6) The implant delivery device of claim 6, wherein the inner shaft includes a slit in which the movable implant supporting flange member is disposed. ### Claim 8 (depends on 7) The implant delivery device of claim 7, wherein the the outer shaft includes a slot into which the movable implant supporting flange member is slid when the inner shaft is moved in the proximal direction. ### Claim 9 (depends on 1) The implant delivery device of claim 1, wherein a distal wall of the recess is beveled. ### Claim 10 An implant delivery device, comprising: an implant holding portion proximate a distal end of the implant delivery device, the implant holding portion being configured to retain a sheet-like implant during implantation of the implant; the implant holding portion being configured to receive the implant with a movable implant supporting flange member configured to retain the implant; wherein the movable implant supporting flange member is configured to be movable between a first position in which the movable implant supporting flange member holds the implant within the recess and a second position in which the implant is unencumbered by the movable implant supporting flange member, thus enabling release of the implant from the implant holding portion of the implant delivery device. ### Claim 11 (depends on 10) The implant delivery device of claim 10, wherein the fixed implant supporting flange member and the movable implant supporting flange member are flexible and resilient such that the fixed implant supporting flange member and the movable implant supporting flange member may be at least partially collapsed upon delivery through a cannula. ### Claim 12 (depends on 10) The implant delivery device of claim 10, wherein the implant is retained in a recess by the movable implant supporting flange member and the fixed implant supporting flange member. ### Claim 13 A method of delivering a sheet-like implant to a surgical site, comprising: providing an implant delivery device with a sheet-like implant secured by an implant holding portion of the implant delivery device such that the implant is held with respect to an outer shaft and between a fixed implant supporting flange member and a movable implant supporting flange member; inserting the implant holding portion of the implant delivery device to a surgical site; moving the movable implant supporting flange member to a second position, thereby allowing the implant to be released. ### Claim 14 (depends on 13) The method of claim 13, further including inserting the outer shaft of the implant delivery device through an access cannula disposed in an incision in a patient's skin. ### Claim 15 (depends on 14) The method of claim 14, wherein the fixed implant supporting flange member and the movable implant supporting flange member are flexible and resilient such that the fixed implant supporting flange member and the movable implant supporting flange member, and the implant have an original unconstrained form, are at least partially collapsed upon delivery through the cannula, and return substantially to the original unconstrained form upon exiting the cannula. ### Claim 16 (depends on 13) The method of claim 13, further including inserting a cannula sealing member disposed about a midportion of the outer shaft into the cannula. ### Claim 17 (depends on 16) The method of claim 16, further including withdrawing the implant delivery device through the cannula, wherein the outer shaft includes a ring disposed distal to the cannula sealing member, and wherein, when the implant delivery device is withdrawn through the cannula, the ring pulls the cannula sealing member out of the cannula. ### Claim 18 (depends on 13) The method of claim 13, wherein the handle includes a slider member, and wherein moving the movable implant supporting flange member is performed by moving the slider member in the proximal direction. ### Claim 19 (depends on 18) The method of claim 18, wherein the implant delivery device includes an inner shaft extending through the outer shaft and connecting the slider member to the movable implant supporting flange member. ### Claim 20 (depends on 19) The method of claim 19, wherein the the outer shaft includes a slot into which the movable implant supporting flange member is slid when the inner shaft is moved in the proximal direction.
