Surgical mesh is a loosely woven sheet which is used as either a permanent or temporary support for organs and other tissues during surgery. Surgical mesh is created from both inorganic and biological materials and is used in a variety of surgeries. Though hernia repair surgery is the most common application, it can also be used for reconstructive work, such as in pelvic organ prolapse.

An apparatus is disclosed for endoscopic application of surgical staples adapted to attach surgical mesh to body tissue in laparoscopic hernia surgery. The apparatus includes a frame, and a generally elongated endoscopic section connected to the frame and extending distally therefrom. A staple storage cartridge is removably supported on a pivotal support system at the distal end portion of the endoscopic section with each staple being configured and adapted to attach the mesh to the body tissue. An elongated pusher system formed of several assembled components and extending from the frame to the endoscopic section is provided for individually advancing at least one staple at a time distally for positioning adjacent the surgical mesh and the body tissue. The pusher system also includes a trigger system to actuate the pusher. The trigger system is provided with perceptible tactile sensing means to indicate when the legs of the staple being advanced are exposed so as to be visible to the user for positioning and orientation purposes. Anvil means provides for individually closing each staple to encompass at least a portion of the surgical mesh and to penetrate the body tissue in a manner to attach the portion of the mesh to the body tissue. Projecting distally of the cartridge support system is a pair of legs which are dimensioned and configured to engage the staple during closure to prevent unwanted roll or deformation outside of the plane of the staple.

InactiveUS20060264948A1Inhibition of attachmentAvoid developmentInternal osteosythesisJoint implantsDura materSurgical department
A bone-anchored surgical mesh has slot-like anchoring members that allow for the variable placement of screws and other bone fasteners. This permits the surgeon discretion in the placement of bone fasteners used to attach the mesh to the patient's bone. The elongate openings of the anchoring members allow for a sliding motion between the bone fasteners and the anchoring members, and facilitates positioning and articulation of the mesh. The anchoring members may include bushings to aid the sliding motion of the anchoring member on the bone fastener. In one embodiment, the mesh consists of shorter modular strips that overlap each other such that a single bone fastener is passed through two overlapping anchoring members to lock the two modular mesh strips together. Additional modular mesh strips can be added on at either end, as desired, to provide the desired length of dural coverage.
