1. A system for closing an aperture in a biological tissue comprising: a first portion of a clip fixedly attached to an arm of a surgical instrument that deploys a surgical implant inside a patient's body, the surgical instrument includes an elongate shaft, wherein the arm and the elongate shaft are parallel in a deployed position and an undeployed position; anda second portion of the clip adapted to releasably receive the surgical implant, wherein the second portion has a first configuration relative to the arm of the surgical instrument that retains the surgical implant and a second configuration relative to the arm of the surgical instrument that releases the surgical implant, the second portion being parallel to the arm of the surgical instrument when in the first configuration and a longitudinal axis of the second portion intersects the arm of the surgical instrument when the second portion is in the second configuration,wherein the clip deforms from the first configuration to the second configuration to release the surgical implant. 2. The system according to claim 1, wherein the clip is made from a resilient material. 3. The system according to claim 1, wherein the clip is made from a deformable material. 4. The system according to claim 1, wherein transformation of the clip from the first configuration to the second configuration is accomplished by an action selected from the group consisting of: downward pulling, backward pulling, and a combination thereof. 5. The system according to claim 1, wherein the first or second portion comprises a shape that prevents early detachment of the surgical implant from the surgical instrument. 6. The system according to claim 1, wherein the clip is composed of a single elastic wire. 7. The system according to claim 6, wherein the single elastic wire is made from a shape memory alloy. 8. The system according to claim 1, wherein the first portion is configured to have a U shape having a protruding portion extending from an end of the U shape. 9. The system according to claim 1, wherein the clip comprises an elastic material, and the second portion of the clip is pre-shaped into the first configuration, wherein the clip is held in a third configuration until contacted with the surgical implant, at which point the second portion of the clip is transformed from the third configuration to the first configuration. 10. A system for closing an aperture in a biological tissue, the system comprising: a handle;an elongate shaft connected to the handle;a deployment scaffold connected to the elongate shaft, the deployment scaffold transitionable between deployed and undeployed configurations, wherein an arm of the deployment scaffold is parallel to the elongate shaft in the deployed and undeployed configurations; andat least one clip connected to the deployment scaffold, the clip including a first portion fixedly coupled to a portion of the deployment scaffold and a second portion extending from the first portion, the second portion transitioning between a first configuration relative to the deployment scaffold and a second configuration relative to the deployment scaffold, the second portion parallel to the deployment scaffold in the first configuration and the second portion defining a longitudinal axis that intersects the deployment scaffold in the second configuration,wherein the system is configured to releasably retain a surgical implant when the second portion of the clip is in the first configuration and the system releases the surgical implant when the second portion of the clip is deformed into the second configuration. 11. The system according to claim 10, wherein the at least one clip has a forward facing orientation. 12. The system according to claim 10, wherein the system deploys and attaches the surgical implant to the biological tissue. 13. The system according to claim 10, wherein the scaffold further comprises: a frame;a plurality of deployment arms hingedly connected to the frame, wherein the plurality of deployment arms are configured to move from a retained position to at least one deployed position;wherein the at least one clip is fixedly attached to the frame. 14. The system according to claim 10, wherein the deployment scaffold is configured to allow for deployment of the surgical implant and retraction of the surgical implant while the scaffold is within a patient's body. 15. The system according to claim 10, wherein the deployment scaffold is configured to allow for a plurality of deployment positions. 16. The system according to claim 10, wherein the deployment scaffold comprises an articulating member that allows for adjustment of a position and an orientation of the surgical implant relative to the aperture in the biological tissue. 17. The system according to claim 10, wherein the surgical implant is a patch. 18. The system according to claim 17, wherein the patch is comprised of surgical mesh. 19. The system according to claim 10, wherein the aperture in the biological tissue is an aperture in an abdominal wall. 20. The system according to claim 10, wherein at least a portion of the elongate shaft is flexible. 21. The system according to claim 10, wherein the elongate shaft is rigid. 22. The system according to claim 10, further comprising at least one stapler adapted to interact with the deployment scaffold. 23. The system according to claim 22, wherein the stapler connects the clip to the deployment scaffold. 24. A system for closing an aperture in a biological tissue comprising: a handle;an elongate shaft connected to the handle;an arm movably coupled to the elongate shaft; anda clip connected to the arm, the clip including a first portion fixedly coupled to a portion of the arm and a second portion extending from the first portion, the second portion transitioning between a first configuration relative to the arm and a second configuration relative to the arm, the second portion parallel to the arm in the first configuration and the second portion defining a longitudinal axis that intersects the arm in the second configuration, wherein the system is configured to releasably retain a surgical implant when the second portion of the clip is in the first configuration and the system releases the surgical implant when the second portion of the clip is deformed into the second configuration, wherein movement of the arm relative to the elongate shaft is parallel movement. 25. The system of claim 24, wherein the surgical implant is released when the second portion of the clip is in the second configuration and the elongate shaft is moved relative to the aperture. 26. The system of claim 24, wherein the surgical implant is released when the second portion of the clip is in the second configuration and the arm is moved relative to the aperture.
