  • Patent number: 11185346
    Abstract: A cutting device is provided having multiple evenly-spaced cutting blades and which is useful for producing tissue forms comprising membranous tissue fragments which are relatively uniformly sized and shaped. The present invention also relates to methods for using the cutter device to quickly and efficiently produce such tissue forms which are useful as grafts and can be flowable and easily passable through a luer-slip tip syringe or needle.

  • Patent number: 10945831
    Abstract: A dermal tissue allograft includes a dermal matrix having a profile including first and second vertices, a first imaginary axis extending between the first and second vertices, a first peripheral edge extending along a continuous path from the first vertex to the second vertex on a first side of the first imaginary axis, and a second peripheral edge extending along a continuous path from the first vertex to the second vertex on a second side of the first imaginary axis. The first peripheral edge includes an apogee, a convex portion, and a concave portion. The convex and concave portions meet at a transition point located on the first peripheral edge between its apogee and the second vertex. The second peripheral edge includes an apogee and is convex. The second perpendicular distance is greater than the first perpendicular distance. The dermal matrix has a substantially uniform thickness across its profile.

  • Patent number: 10695157
    Abstract: A tissue graft packaging system having a retainer including first and second members with respective first and second pluralities of channel sidewalls that define first and second pluralities of channels, and first and second engagement means configured to removeably interconnect the first and second members. The first and second pluralities of channel sidewalls are configured to create a continuous interior space between the first and second members. A tissue graft, such as a cryopreserved viable tissue graft, is contained within the continuous interior space of the retainer. Processes for packaging, thawing and rinsing the tissue graft using the tissue graft packaging system and its retainer are also disclosed.

  • Patent number: 9180043
    Abstract: An apparatus to minimize and/or eliminate the effects associated with reperfusion injury consisting of an external pump, heat exchanger and control unit creating a flow loop whereby blood is moved from the body via a pump, cooled by an external heat exchanger and reintroduced into a specific location, thereby locally cooling the surrounding tissue and inducing localized hypothermia to minimize tissue injury resulting from ischemia and the effects associated with reperfusion injury as an obstruction is removed and normal blood flow is restored and including the ability to locally measure pressure and temperature in the body.
