  • Endoscopic fascial closure devices and methods for using same
    Patent number: 9498209
    Abstract: A system for closure of a fascial opening is disclosed. The system may include a first capture device for pulling one end of a suture through fascial tissue on one side of a fascial opening, and a second capture device for pulling an opposing end of the suture through the fascial tissue on an opposite side of the fascial opening. A trapping device for locating and engaging the first capture device can be used, prior to the capture device being pulled through the fascial tissue, so that the trapping device can subsequently pull the suture to facilitate closure of the fascial opening. Methods and apparatuses for closure of a fascial opening are also disclosed.
