Abstract
The present invention pertains to a patch of flexible surgical mesh material having at least one elongated semi-rigid member secured to the mesh material for use in facilitating positioning of the mesh material in surgical operations. In variant embodiments of the invention a plurality of semi-rigid members are formed either integrally with the flexible mesh as a single unit of the same material, or as separate component parts secured to the mesh material.
Claims25
In a surgical mesh for overlaying a body tissue opening to cover the opening and allow for tissue ingrowth within the surgical mesh, the improvement comprising:
- a thin patch of flexible mesh material, the patch having an area configuration defined by a peripheral edge extending completely around a periphery of the patch, the peripheral edge having substantially the same flexibility as the mesh material of the patch;
- at least one semi-rigid member having a length with opposite first and second ends, the member having a narrow, elongated configuration and a cross-sectional width that is larger than a thickness of the patch mesh material, the member being permanently secured along its length to the patch mesh material, and the member having less flexibility than the flexibility of the patch peripheral edge and the mesh material of the patch.
In a surgical mesh for overlaying a body tissue opening to cover the opening and allow for tissue ingrowth within the surgical mesh, the improvement comprising:
- a thin patch of flexible mesh material, the patch having an area configuration defined by a peripheral edge extending completely around a periphery of the patch and the mesh material being continuous and having no interruptions within the peripheral edge, the peripheral edge having substantially the same flexibility as the mesh material of the patch;
- a first semi-rigid member having less flexibility than the peripheral edge and the mesh material of the patch, the first member having a length with opposite first and second ends, the first member having a narrow elongated configuration and a cross-sectional width that is larger than a thickness of the patch mesh material, the first semi-rigid member being secured along its length to the patch juxtaposed along a portion of the peripheral edge;
- and
- a second semi-rigid member having less flexibility than the peripheral edge and the mesh material of the patch, the second member having a length with opposite first and second ends, the second member having a narrow elongated configuration and a cross-sectional width that is larger than a thickness of the patch mesh material, the second semi-rigid member being secured along its length to the patch spaced from the first semi-rigid member and juxtaposed along a portion of the peripheral edge.
In a surgical mesh for overlaying an opening in a body tissue to cover the opening and allow for tissue ingrowth within the mesh, the improvement comprising:
- a thin patch of flexible mesh material having opposite front and back surfaces, the patch having an area configuration defined by a peripheral edge extending completely around the area of the patch, the peripheral edge having substantially the same flexibility as the mesh material of the patch;
- and
- a semi-rigid member having a length with opposite first and second ends, the member being secured to only a portion of the peripheral edge of the patch, the member having less flexibility than the flexibility of the peripheral edge and mesh material of the patch and the member having a rigidity and a configuration on the patch that projects the member uprightly out from the front surface of the patch whereby the member provides means on the patch for grasping by a surgical grasper and manipulating the means by the grasper and thereby simultaneously manipulating the entire area of the patch while resisting folding of the patch at its peripheral edge as the patch is manipulated.
