Arthrex Amnion matrix is rich in growth factors and contains regenerative qualities that maintain the natural healing properties of amnion. Used as an anatomical barrier or wrap in a variety of orthopedic applications, Arthrex Amnion matrix provides essential biological and mechanical protection while helping to prevent adhesion.1

John M. Tokish, MD (Scottsdale, AZ), demonstrates how to load a 5 mm × 40 mm amnion strip into the AmnionXpress™ delivery device. The AmnionXpress delivery device allows for the precise delivery of an amniotic tissue matrix directly into pathologic tissues. The natural properties of Arthrex Amnion™ matrices help provide an anatomic barrier to aid in providing mechanical protection, while proprietary processing retains nutrient-rich growth factors essential for signaling.

AmnionXpress™ Delivery Device

Here is all of the things that you need in order to load the amnion streamer onto the AmnionXpress device. I actually don't need the ruler, but we we just wanted to demonstrate for you, show you the length and a couple of of pearls on how to get this loaded easily, properly and consistently. So you'll notice that the the precut streamer comes to an exact length of 40mm. And what I've done is just taken a marking pen that is available in every Or set. And I've just made a mark at the 20 millimeter mark here that you can see. What this does is it gives us the 50 yard line or the halfway view. And this is the depth at which you want to load this into the AmnionXpress device. So ideally we would like this loading it all the way just halfway in. And let the fork capture right at this point. The reason this is, is that it makes sure that you've got equidistant limbs from either side. Remember that the deployed fork is exactly 30mm. And while if you've got it doubled, if you've got it doubled, then that means that the 20 millimeter half distance here will always be too short to get caught in the tube. So if one were to load not at the 50 yard line view, but say loaded at, say, the ten millimeter view, then you'd have ten millimeters on this side and 30mm left on the other side. You can imagine that 30mm. You could run the risk of having it sort of caught up inside the tube. So we mark this at the 50 yard line to guarantee that there's never any capture. The next thing that we do is we're going to get this loaded on the inside of the slot and get it ready for pre-deployment. The streamer is wide enough that it won't fit through the slot just coming, so we fold the streamer in while it's dry in half, at least for the first half of it. And that allows us then to have easy access directly into the slot. And I'll load that right to the 50 yard line shot there. So now you can see the dry Amion streamer loaded correctly in the slot at the 50 yard line. You can see the mark that we had placed on the amnion streamer. The purple is shown just there at the top, and you can see that I've got it directly loaded in guaranteeing an equidistance between the two limbs once it gets folded down and captured. Now we're going to going to hydrate the graft, and you'll see that once it gets hydrated, it becomes quite flimsy to work with. This was one of the challenges with working with amnion is that once it is wet, it becomes pretty difficult to maneuver around. And as I say, it will hold a stitch, but it can become a little bit tricky to do it. It's nice and strong, but very flexible. And that's the loaded amnion streamer after it's been wet. And we simply then now need to insert it into the terminal portion of the of the AmnionXpress. And so I do that by now just taking my thumb. And we slowly and consistently insert it until we get to the second button. You can see the amnion disappear. Then if you take a look at the very tip of the amnion express Inserter once I'm pushed into this position, you you can see just the hint that something is going to go, but it's completely protected within the sheath of the distal portion of the amnion express. And now it's totally ready for insertion.

TenoWrap collagen tendon wrap is a resorbable type I collagen matrix that provides a nonconstricting encasement for tendons, a protected environment, and a gliding surface for the tendon sheath. Designed to be an interface between the tendon and surrounding tissue, TenoWrap grafts are a conformable, nonfriable, self-curling collagen sheet for easy placement under, around, or over an injured tendon.
