  • Publication number: 20230190261
    Abstract: Techniques are described for closure of a defect in material, such as closure of a laparoscopic surgical defect. A defect closure device can be inserted into the defect to capture first material adjacent to the defect. The device houses at least first and second suture pins coupled together by a suture. A first interaction with a trigger structure can force the first suture pin through the captured first material and into a containment sub-assembly. After rotating the device to capture second material adjacent to the defect, a second interaction with the trigger structure can force the second suture pin through the captured second material and into the containment sub-assembly. As such, the suture is passed through the first and second portions of the material, and the ends of the suture can be cinched, and cut to form a stitch.

  • Patent number: 10448939
    Abstract: Embodiments include systems and methods for closure of a hole or other defect, for example in context of a laparoscopic surgical procedure. For example, a suturing device and method of use involve inserting the device into a hole, positioning material around the hole into a notch of the device, passing a needle through a cavity in the device and the material positioned in the notch, passing a suture through the eye of the needle, and removing the needle from the material with the suture. The suture can be removed and the process can be repeated with another end of the suture at another location through the material, around the hole. When the suture is passed through the second point of penetration, the suture can now extend both into and out of the material at different points around the hole and can be tied, thereby closing the hole.

  • Publication number: 20180049731
    Abstract: There are shown and described embodiments of closure devices and systems for closing holes in tissue such as those caused unintentionally (e.g. hernia) or intentionally (e.g. openings in the right atrial appendage to access cardiac tissue). Such devices and systems include one or more mesh elements or anchors. In particular embodiments, a closure device includes first and second mesh closure members and a tether or stem connecting them. Embodiments of a delivery device for such closure devices are also described.

  • Patent number: 9375137
    Abstract: The invention is a lighted gastric surgical bougie which includes an integral light source disposed at the distal end that, when activated, is detectable through the gastric wall of a patient during gastric surgery. The light source enables a surgeon to identify the location of the bougie within the patient. The light source may include at least one LED integrally disposed at the distal end. Optionally, a second LED is integrally disposed on the main body a longitudinal distance away from the at least one LED at the distal end. The second LED may be disposed near the tapered region so that a surgeon can readily identify the location of the tapered region with respect to the patient's anatomy. Preferably, the second LED at the proximal portion of the tapered region is visibly different than the at least one LED. Alternatively, the light source is chemiluminescent.
