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 method of deploying one or more surgical meshes comprising:

providing an actuation unit including a handle assembly a shaft extending from the handle assembly, and a shipping lock releasably secured to the handle assembly;

providing a mesh deployment unit configured for releasable connection to the actuation unit, the mesh deployment unit including a lock member for securing the mesh deployment unit in an expanded configuration;

connecting the mesh deployment unit to the actuation unit; and

separating the shipping lock from the handle assembly.

2. The method of claim 1, further including securing the mesh deployment unit to the actuation unit.

3. The method of claim 2, wherein securing the mesh deployment unit to the actuation unit includes advancing a retaining sleeve of the actuation unit into engagement with a linear actuator of the mesh deployment unit to cause the release of the lock member.

4. The method of claim 3, wherein connecting the mesh deployment unit to the actuation unit includes connecting a connector member of the mesh deployment unit to a connection member of the actuation unit.

5. The method of claim 3, further including separating the lock member from the mesh deployment unit.

6. The method of claim 1, further including advancing a deployment handle of the actuation unit to collapse a frame assembly of the mesh deployment unit.

7. The method of claim 6, further including inserting the frame assembly of the mesh deployment unit into a body cavity of a patient.

8. The method of claim 6, further including retracting the deployment handle to expand the frame assembly of the mesh deployment unit.

9. The method of claim 8, further including re-advancing the deployment handle of the actuation unit to collapse the frame assembly of the mesh deployment unit.

10. The method of claim 6, further including rotating an articulation knob of the actuation unit to cause articulation of the frame assembly relative to the actuation unit.

11. The method of claim 10, further including securing a mesh to the frame assembly of the mesh deployment unit.

12. The method of claim 11, further including retracting a trigger member to release the mesh from the frame assembly.

13. The method of claim 12, further including activating a safety switch to permit retraction of the trigger member.

14. The method of claim 6, further including receiving the frame assembly of the mesh deployment unit in a furling tube.

15. The method of claim 6, further including actuating mesh release assemblies supported within the frame assembly to cause the release of a mesh from the mesh deployment unit.

16. The method of claim 15, wherein actuating the mesh release assemblies includes retracting a trigger of the actuation unit.

17. The method of claim 1, wherein the mesh deployment unit includes a mesh releasably affixed to a frame assembly, a shaft assembly extending from the frame assembly, and the lock member releasably secured to the shaft assembly for securing the frame assembly in the expanded configuration.

18. A method of deploying one or more surgical meshes comprising:

securing a mesh deployment unit to an actuation unit, the mesh deployment unit including a mesh releasably affixed to a frame assembly, a shaft assembly extending from the frame assembly, and a lock member releasably secured to the shaft assembly for securing the frame assembly in an expanded configuration;

separating the lock member from the shaft assembly of the mesh deployment unit to permit collapse of the frame assembly;

collapsing the frame assembly;

inserting the collapsed frame assembly into a patient;

expanding the frame assembly within a patient; and

releasing the mesh from the frame assembly.

19. The method of claim 18, wherein the actuation unit includes a handle assembly and a shaft extending from the handle assembly.

20. A method of deploying one or more surgical meshes comprising:

providing an actuation unit including a handle assembly and a shaft extending from the handle assembly;

providing a mesh deployment unit configured for releasable connection to the actuation unit, the mesh deployment unit including a lock member for securing the mesh deployment unit in an expanded configuration; and

connecting the mesh deployment unit to the actuation unit; and

securing the mesh deployment unit to the actuation unit by advancing a retaining sleeve of the actuation unit into engagement with a linear actuator of the mesh deployment unit to cause the release of the lock member.

21. A method of deploying one or more surgical meshes comprising:

providing an actuation unit including a handle assembly and a shaft extending from the handle assembly;

providing a mesh deployment unit configured for releasable connection to the actuation unit, the mesh deployment unit including a mesh releasably affixed to a frame assembly, a shaft assembly extending from the frame assembly, and a lock member releasably secured to the shaft assembly for securing the frame assembly in an expanded configuration; and

connecting the mesh deployment unit to the actuation unit.
