Abstract

A mesh deployment device having separate mesh deployment and actuation units is provided. A mesh deployment device includes an actuation unit and a mesh deployment unit configured to be releasably secured to the actuation unit. When the mesh deployment unit is secured to the actuation unit, a first actuation of the actuation unit moves the mesh deployment unit from an expanded condition to a collapsed condition and a second actuation of the actuation unit moves the mesh deployment unit from the collapsed condition to the expanded condition. The mesh deployment device may further include a mesh releasably secured to the mesh deployment unit. A third actuation of the actuation unit may release the mesh from the mesh deployment unit. Also provided is a kit including multiple mesh deployment units.

Claims

1. A mesh deployment unit configured for selective connection to an actuation unit, the mesh deployment unit comprising:

a frame assembly including first and second frame members configured for releasable support of a mesh, each of the first and second frame members includes a mesh release assembly for selectively securing a mesh to the frame assembly;

a connector assembly operably connected to the frame assembly, the connector assembly including a connector member configured for selective attachment to an actuation unit; and

an actuator assembly including an actuator shaft extending from the frame assembly through the connector assembly, a proximal end of the actuator shaft being disposed within the connector member and being operably engageable with a deployment rod of the actuation unit, each mesh release assembly includes a release link operably connected to the actuator assembly, and at least one clip pivotally secured to the release link for releasably securing the mesh to the frame assembly, each release link being configured for movement from a first position to a second position to cause the movement of the at least one clip of each of the mesh release assemblies from a locked position for retaining the mesh to the frame assembly, to an unlocked position, to permit the release of the mesh from the frame assembly, wherein each of the first and second frame members includes a respective first ramp member configured to frictionally retain each release link in the first position.

2. The mesh deployment unit of claim 1, wherein movement of the actuator assembly in a first axial direction relative to the connector assembly is configured to move the frame assembly from an expanded condition to a collapsed condition.

3. The mesh deployment unit of claim 2, wherein movement of the actuator assembly in a second axial direction relative to the connector assembly is configured to return the frame assembly to the expanded condition.

4. The mesh deployment unit of claim 1, wherein the actuator assembly is configured to cause movement of each release link from the first position to the second position.

5. The mesh deployment unit of claim 1, wherein each clip of the at least one clip of each of the mesh release assemblies is configured to move from the locked position to the unlocked position during an actuation of the actuation unit.

6. The mesh deployment unit of claim 5, wherein each clip of the at least one clip of each of the mesh release assemblies includes an arcuate flange portion.

7. The mesh deployment unit of claim 1, wherein each of the first and second frame members includes a respective second ramp member configured to frictionally retain each release link in the second position.

8. The mesh deployment unit of claim 1, wherein the first frame member includes a sliding portion, a connector portion, a proximal link portion, an attachment portion, a distal link portion, and an end portion and the second frame member includes a static portion, a connector portion, a proximal link portion, an attachment portion, a distal link portion, and an end portion.

9. The mesh deployment unit of claim 8, wherein the sliding portion of the first frame member is configured for longitudinal movement relative to the static portion of the second frame member to cause articulation of the frame assembly.

10. The mesh deployment unit of claim 1, further including a mesh selectively secured to the frame assembly.

11. The mesh deployment unit of claim 1, wherein at least a portion of the actuator shaft includes a rectangular cross-section.

12. The mesh deployment unit of claim 1, further including a locking member selectively securable to the connector assembly, wherein the connector assembly includes a lockout member configured for selectively engaging the locking member.

13. The mesh deployment unit of claim 12, wherein the lockout member is movable from a first position in engagement with the locking member to a second position disengaged from the locking member.

14. The device of claim 1, further including an articulation link extending from the frame assembly through the connector assembly, wherein a proximal end of the actuator shaft is disposed within the connector member and is operably engageable with a articulation linkage of the actuation unit.

15. A mesh deployment unit configured for selective connection to an actuation unit, the mesh deployment unit comprising:

a frame assembly including first and second frame members; and

a mesh release assembly operably supported within each of the first and second frame members for selectively securing a mesh to the frame assembly, each mesh release assembly includes a release link operably connected to an actuator assembly, and at least one clip pivotally secured to the release link for releasably securing the mesh to the frame assembly, wherein each release link is configured for movement from a first position to a second position to cause the movement of the at least one clip of each of the mesh release assemblies from a locked position for retaining the mesh to the frame assembly, to an unlocked position, to permit the release of the mesh from the frame assembly, wherein each of the first and second frame members includes a respective first ramp member configured to frictionally retain each release link in the first position.

16. The mesh deployment unit of claim 15, wherein each of the first and second frame members includes a respective second ramp member configured to frictionally retain each release link in the second position.
