  • Publication number: 20210204933
    Abstract: A reinforcing incision drape for tissue, such as fragile tissue, includes an absorbable surgical mesh having top and bottom major surfaces. The absorbable surgical mesh has a stitching zone and first and second reinforcing zones that bound opposite sides of the stitching zone. The stitching zone is less porous and the first and second reinforcing zones are more porous than the stitching zone. A releasable liner covers the top major surface of the absorbable surgical mesh within the stitching zone of the absorbable surgical mesh. A weaker adhesive, such as a pressure sensitive adhesive, covers the bottom major surface of the surgical mesh within the centrally located stitching zone of the absorbable surgical mesh, and a stronger adhesive, such as cyanoacrylite, covers the first and second reinforcing zones of the absorbable surgical mesh.

  • Patent number: 10945720
    Abstract: A method of reinforcing subcutaneous fragile tissue includes obtaining an absorbable surgical mesh having top and bottom major surfaces, the absorbable surgical mesh including a stitching zone and first and second reinforcing zones that bound opposite sides of the stitching zone. The method includes making an incision in a patient's skin for exposing subcutaneous fragile tissue, using one or more absorbable adhesives for adhering the bottom major surface of the absorbable surgical mesh to the subcutaneous fragile tissue, creating an incision through the stitching zone of the absorbable surgical mesh and into the subcutaneous fragile tissue, performing a surgical procedure through the incision, and passing an absorbable suture through the stitching zone of the absorbable surgical mesh and the fragile tissue for closing the incision.

  • Publication number: 20210045741
    Abstract: A reconfigurable suture needle includes an elongated body having a curved proximal section and a curved distal section. A joint interconnects a distal end of the curved proximal section and a proximal end of the curved distal section. The joint enables the curved proximal section and the curved distal section to rotate relative to one another between a first configuration having a higher profile and a second configuration having a lower profile. Each of the curved proximal and distal sections of the elongated body defines about one-quarter of a circle. The elongated body has a semi-circular shape when in the first configuration and a wave shape when in the second configuration. The elongated body is rotated into the smaller profile for passing through a cannula and, after passing through the cannula, rotated back into the higher profile for use as a suturing needle.
