  • Patent number: 10898312
    Abstract: Fenestrated tissue grafts and acellular dermal matrices (ADMs) for use, for example, in breast reconstruction, are disclosed herein. In various embodiments, the improved tissue grafts are used in two-stage tissue expander breast reconstruction. Disclosed embodiments include altered ADMs and other tissue grafts, which comprise strategically placed fenestrations, and methods of making the same. The addition of specific patterns of fenestrations in the graft improve the breast reconstructive experience by increasing intra-operative fill volume and decreasing time to full expansion; such alterations to the graft may also increase cosmetic outcomes and patient comfort. In some embodiments, particular lengths, shapes, and measurements of overlap are used in the fenestration pattern.

  • Patent number: 10881499
    Abstract: Techniques and reconstruction systems for ligament repair and fixation. A bone tendon graft is prepared by folding the bone block over a suspensory fixation device (for example, a knotless suture construct such as a knotless, adjustable, self-cinching suture loop/button construct, a suture, crosspin, or screw, etc.). A flexible strand is then used to suture the bone plug to the tendon so that the overall graft is shortened significantly and the suspensory fixation device is securely attached. The technique does not require passage of the suspensory fixation device through the bone block which makes the graft passage easier since the graft is pulled from the tip. The technique also allows shortening of the overall graft.
