  • Publication number: 20160256253
    Abstract: An endoscopic system for winding and inserting a mesh into an abdominal cavity of a patient is provided. The endoscopic system includes an introducer having an elongated shaft extending distally therefrom. The shaft includes a split portion that defines an opening therealong. The split portion is configured to support the mesh within the opening. A furler defining a lumen is engageable with the split portion of the shaft and configured to exert a radial force onto the mesh that is supported by the split portion. Rotation of one of the furler and introducer with respect to the other winds the mesh inside the furler to a diameter smaller than a diameter of the lumen of the furler.

  • Patent number: 8968760
    Abstract: A method for attaching an implant to tissue is disclosed. In embodiments, a method includes applying a sprayable material to tissue, the sprayable material possessing functional groups capable of binding to tissue. The sprayable material also possesses functional groups capable of binding to an implant. In embodiments, the functional groups capable of binding to an implant include nucleotides. In such a case, the implant possesses complementary nucleotides capable of binding to the nucleotides on the sprayable material, thereby permitting hydrogen binding between the two. The implant may thus be affixed to tissue, and repositioned as necessary, prior to more permanent attachment utilizing means such as sutures, tacks, etc.
