In particular, the mesh deployment device includes an arm assembly that is transitionable between a retracted configuration, in which, stationary and covering arms are in superposed relation such that the surgical mesh is supported by the supporting arm therebetween, and a deployed configuration, in which, the stationary, covering, and supporting arms are circumferentially spaced apart to support the surgical mesh thereon. ## Claims ### Claim 1 A mesh deployment device comprising: a body portion defining a lumen; a rotating knob rotatably supported on the body portion; an arm assembly operatively coupled with the rotating knob, the arm assembly including: a stationary arm coupled to the body portion; a covering arm coupled to the rotating knob for concomitant rotation with the rotating knob; and a supporting arm rotatably coupled with the covering arm; and a surgical mesh secured to the arm assembly, wherein the arm assembly is transitionable between a retracted configuration, in which, the stationary and covering arms are in registration with each other such that the surgical mesh is folded between the stationary arm and the covering arm by the supporting arm, and a deployed configuration, in which, the stationary arm and the covering arm are circumferentially arranged to spread the surgical mesh. ### Claim 2 (depends on 1) The mesh deployment device according to claim 1, wherein the stationary arm is non-rotatably fixed to the body portion. ### Claim 3 (depends on 2) The mesh deployment device according to claim 2, wherein the stationary arm is distal of the covering arm. ### Claim 4 (depends on 1) The mesh deployment device according to claim 1, wherein the surgical mesh defines a slit. ### Claim 5 (depends on 4) The mesh deployment device according to claim 4, wherein the surgical mesh has a first edge and a second edge, and wherein the slit is defined in the first edge and the second edge, the first edge and second edge being secured with the respective stationary arm and covering arm. ### Claim 6 (depends on 1) The mesh deployment device according to claim 1, further comprising a string securing the surgical mesh to the arm assembly. ### Claim 7 (depends on 6) The mesh deployment device according to claim 6, wherein the body portion defines a lateral opening in communication with the lumen of the body portion, the string extending from the arm assembly to the opening of the body portion through the lumen. ### Claim 8 (depends on 1) The mesh deployment device according to claim 1, wherein the stationary arm includes a first base, a first guide wall extending proximally from the first base, and a core extending proximally from the first base and connected to the body portion. ### Claim 9 (depends on 8) The mesh deployment device according to claim 8, wherein the stationary arm further includes stoppers extending radially outward from the core. ### Claim 10 (depends on 9) The mesh deployment device according to claim 9, wherein the covering arm has: a second base; and a second guide wall extending distally from the second base and defining a first cutout. ### Claim 11 (depends on 10) The mesh deployment device according to claim 10, wherein the first guide wall and the second guide wall are on opposing sides of the arm assembly in the retracted configuration. ### Claim 12 (depends on 10) The mesh deployment device according to claim 10, wherein the first guide wall and the second guide wall are adjacent each other when the arm assembly is in the deployed configuration. ### Claim 13 (depends on 10) The mesh deployment device according to claim 10, wherein a first stopper of the core is configured to engage the first cutout of the covering arm to limit an amount of rotation of the covering arm. ### Claim 14 (depends on 10) The mesh deployment device according to claim 10, wherein the supporting arm includes an engaging portion rotatably supported about the core of the stationary arm. ### Claim 15 (depends on 14) The mesh deployment device according to claim 14, wherein the engaging portion of the supporting arm defines a second cutout configured to engage a second stopper of the core such that the second stopper limits an amount of rotation of the supporting arm. ### Claim 16 (depends on 14) The mesh deployment device according to claim 14, wherein the stationary arm and the covering arm define bores to receive a string therethrough. ### Claim 17 A mesh deployment device comprising: a body portion; a rotating knob rotatably supported on the body portion; a surgical mesh; and an arm assembly releasably securing the surgical mesh, the arm assembly operatively coupled to the rotating knob such that the arm assembly is rotatable about the body portion, the arm assembly including: a stationary arm coupled to the body portion; a covering arm coupled to the rotating knob for concomitant rotation with the rotating knob; and a supporting arm rotatably coupled with the covering arm, wherein the arm assembly is transitionable between a retracted configuration, in which, the stationary arm and the covering arm are in superposed relation such that the surgical mesh is supported by the supporting arm, and a deployed configuration, in which, the stationary arm, the covering arm, and the supporting arm are circumferentially spaced apart to support the surgical mesh. ### Claim 18 (depends on 17) The mesh deployment device according to claim 17, wherein the arm assembly is orthogonal to the body portion. ### Claim 19 A mesh deployment device comprising: a stationary arm coupled to an elongate body portion, the stationary arm extending at an angle relative to a longitudinal axis of the elongate body portion; a rotating knob rotatably supported in the elongate body portion for rotation about the longitudinal axis of the elongate body portion; an arm assembly operatively coupled with the rotating knob, the arm assembly including: a covering arm coupled to the rotating knob for concomitant rotation with the rotating knob and relative to the covering arm, the covering arm extending parallel to the stationary arm; and a supporting arm rotatably coupled to the rotating knob for concomitant rotation with the rotating knob and relative to the covering arm, the supporting arm extending parallel to the stationary arm and between the stationary arm and the covering arm; and a surgical mesh secured to the stationary arm and to each of the covering arm and the supporting arm of the arm assembly, wherein the arm assembly is transitionable between a retracted configuration, in which, the stationary arm, the covering arm and the supporting arm are in registration with each other such that the surgical mesh is folded between the stationary arm, the covering arm and the supporting arm, and a deployed configuration, in which, the stationary arm, the covering arm and the supporting arm are spaced apart to spread the surgical mesh. ### Claim 20 (depends on 19) The mesh deployment device according to claim 19, wherein the covering arm and the supporting arm are rotatable about a common axis relative to the stationary arm.
