Patent ID: 8579989

Claim:
A device for use in parietal surgery, the device comprising: a body; a shaft movably disposed along the body; a parietal surgical implant in the form of a mesh adapted for use in repairing hernias, the parietal surgical implant being locatable in a collapsed state within the body, the parietal surgical implant being adapted to be displaceable between the collapsed state and an expanded state; a mechanism for expanding the parietal surgical implant from the collapsed state into the expanded state; a mechanism for retaining the parietal surgical implant within the body in the collapsed state, the retaining mechanism comprising a sleeve within which the parietal surgical implant is locatable, the sleeve being displaceable relative to the parietal surgical implant in order to expose the parietal surgical implant; the mesh of the parietal surgical implant having a mesh perimeter and a shaft mounting area, the mesh being mounted to the shaft via the shaft mounting area; the expanding mechanism comprising a collar slidably mounted about the shaft, and at least one arm mounted between the collar and an arm mounting position of the mesh, the arm mounting position being spaced apart from the shaft mounting area, the collar being displaceable towards the mesh in order to urge the mesh towards the expanded state; and an abutment seated against the collar and a cut end of the shaft to retain the mesh in its expanded state at the hernia once the cut end of the shaft is separated from a remainder of the shaft, the abutment having a recess within which the cut end of the shaft is seated, such that the abutment covers the cut end of the shaft and distributes pressure exerted by the cut end of the shaft following the closure of a surgical incision through which the hernia is accessed by the device.
