3 What is Stravix? Stravix is a viable cryopreserved human placental tissue comprised of umbilical amnion and Wharton s jelly Contains collagen and HA-rich extracellular matrix, growth factors, and viable cells native to the tissue. Designed to be used as a surgical covering or wrap for damaged or inadequate integument Can be used over tendon

6 Benefits Anti-adhesion and anti-inflammatory barrier aids natural wound repair, reduces inflammation, reduces scarring, and protects from infection Designed for application directly to acute and chronic wounds Thicker and stronger than amnion alone Immune neutral Alternative to autologous skin grafting that eliminates the pain, comorbidities and procedure time associated with obtaining autologous grafts

7 Indications Limited to the homologous use as a wound cover or surgical wrap. The product may be used to cover or wrap acute and chronic wounds, including but not limited to: diabetic foot ulcers, venous leg ulcers, pressure ulcers, dehisced surgical wounds, acute surgical wounds, Pyoderma Gangrenosum and Epidermolysis Bullosa. may be used in wounds encompassing both upper extremity and lower extremity acute and chronic wounds. naturally conforms to complex anatomies and may be used over exposed bone, nerves, tendon, joint capsule, muscle, hardware, and surgical mesh. Contraindications There are no known contraindications

18 The Medical Fish Skin Company

19 Acelullar fish skins is used for wound healing Fish skin is harvested from wild Atlantic cod. Cells are gently removed from the skins Intact fish skin remains, with all components preserved; proteins, glycans and fats (including Omega3s) The graft is applied to human wounds were it recruits stem cells and facilitates tissue regeneration

20 Skin substitute with Omega3 Molecules in human skin Collagens Elastin Laminin Fibronectin Proteoglycans (e.g. decorin) Glycosaminoglycans Lipids Molecules in acellular fish skin Collagens Elastin Laminin Fibronectin Proteoglycans Glycosaminoglycans Lipids (high proportion being Omega3 s)

21 Advantages of fish skin compared to mammalian tissues Fish Skin Minimal Processing No viral risk Acellular Fish Skin Intact, strong, suturable Structure Preserved Proteins, Glycans and Fats Preserved Omega3 fatty acids Mammalian Tissue Intensive Processing Substantial viral risk Collagen Most structural components washed away with strong detergents Only the most non-soluble collagens remain

22 Human- and Fish Skin Structural Comparison Acellular Fish Skin Human Skin Fundamental structure is similar The key difference is: Scales (all removed) instead of hairs Omega3 1 µm 1 µm Fish skin: >30% Human skin: <1% Amniotic Membrane: <1% Rakers S. Et al. Fish matters : the relevance of fish skin biology to investigative dermatology. Experimental Dermatology 2010; 19:

23 Why do we look at cell ingrowth? The most obvious feature of chronic wounds is the failure to re-epithelialize Failure is most often due to keratinocyte migration problems rather than failure to proliferate Failure of migration may occur due to Lack of functional Extracellular Matrix for adherence Excessive inflammation and protease activity Altered cytokine expression and distribution

24 Cell Migration as marker of functional Extracellular Matrix Achieving cell ingrowth into a skin substitute demonstrates functional ability to Protect ECM components, growth factors and receptors from degradation Modulate inflammatory response Provide scaffold to direct cells into the injury as well as stimulating them to proliferate, differentiate and synthesize new ECM

25 Discussion on Fish Skin Promising skin substitute for tissue regeneration Has shown faster healing in RCT (n=162) compared to mammalian sourced skin substitutes Rich in Omega3 fatty acids that Promotes cell migration Natural bacterial barrier without cytotoxicity

26 Key difference of Fish Skin No viral transmission from N. Atlantic Cod to humans Allows for gentle processing retaining Three Dimensional Structure Fatty Acids Omega3 Extracellular Matrix Component No Cultural or religious concerns Wild caught through responsible fisheries

27 Use of Acellular Fish Skin Biologic cover of the wound that have excessive inflammation, and provides a scaffold for in-growth Wound healing can be slowed down by: Venous insufficiency Diabetes Peripheral arterial disease Or by temporary complicating factors: Inflammation or eczema in skin Infection Too dry or too wet wound environment Pressure Maceration of DFU Bacterial bio-film in venous ulcer

28 Modes of Action Facilitates healing through tissue regeneration by using unique healing benefits of acellular fish skin and the components thereof. Decrease inflammation by reducing MMP activity Dermal scaffold for cellular in-growth Bacterial barrier Replenishes Omega3 to reduce inflammation Maintains moist wound environment with vapor permeability of human skin Healing of a chronic wounds requires treating the underlying disease. Reduces factors that prevent regular healing to commence and increases healing rate Scaffold for cell in-growth Skin graft

36 ENLUXTRA ENLUXTRA Smart Wound Dressing is the first and only selfregulating super-absorbent fiber wound dressing smart built-in adaptive hydration and selective wound cleansing function

37 Made of proprietary feedback driven smart polymers adapts its local function to provide optimal treatment for all different wound zones simultaneously, effectively evacuates disintegrated non-viable tissues from the wound

38 Unlike other moist dressings, continuously evacuates multiple products of natural autolytic debridement from the wound bed. This includes liquefied debris of necrotic tissue and slough, along with harmful microorganisms and disintegrated biofilms. The wound quickly becomes clean, and stays clean. This natural cleansing process works as needed while stays on a wound, and is critical for faster wound healing.

39 Indications Works for most wounds. With its variable local functionality and superabsorbency Useful for pressure ulcers in any stage, non-healing chronic wounds, postoperative wound complications, diabetic ulcers, heavily draining wounds, venous ulcers, thermal, chemical and radiation burns, wounds with slough and/or necrosis, wounds caused by sickle cell anemia, and many other types of wounds It is hypoallergenic, latex free, bio-inert, non-toxic, contains no active medications

42 DO NOT pack into wound cavity. DO NOT use wound fillers that shrink (such as alginates) DO NOT use thick and viscous pastes (such as petroleum based products or honey) DO NOT use alginate, hydro-cellulose fibers or collagen dressings under

43

44 Usage Slough consists of solid and viscous components. Under this dressing these components get liquefied by natural autolytic process and absorbed by the dressing along with the exudate fluid. The absorbed components are removed as the dressing is changed. Odor reduction follows concurrently. Typically the process takes 3-6 dressing changes to remove slough and odor completely During the slough removal process, change the dressing every 1-2 days to avoid dressing overload by the solid slough components. Follow these steps: Rinse a wound with sterile saline before each dressing application. Change dressing every 1-2 days for the first 1-2 weeks or until slough and odor are 80% removed. Then you may gradually increase wear time to 5-7 days until the wound is healed.

45 CONTRAINDICATIONS Known sensitivity Heavy arterial bleeding PRECAUTIONS AND WARNINGS Sterile unless damaged or opened Single-use Store at temperatures below 100 F CONSULT A CLINICIAN If you notice any of following: Redness or warmth around the wound Pain or tenderness Unusual odor Excessive drainage or change in color

46 Case study: Diabetic foot ulcer secondary to gout A 60-year-old female presented with a diabetic foot ulcer secondary to gout and neuropathy on the lateral side of her right foot great toe.

49 The Cutimed TCC Kit Total Contact Casting - Clinically Effective Approach to Healing Dr. David Armstrong and his colleagues' research results showed that TCC heals a higher proportion of wounds in a shorter amount of time over the two other widely used offloading modalities the Removable Cast Walker (RCW) and the half-shoe (P=0.026). Fiberglass and plaster casts retain their rigidity over time, healing the ulcer over a shorter period Wounds achieving less than 53% closure at week four have minimal chance of healing with conventional therapy. 90% of all non-ischemic ulcers without infection Average time to heal = 34 days

50 By definition, a Total Contact Cast is rigid and is the 'Gold Standard' in the management/healing of DFUs. It incorporates all components necessary for providing a truly rigid casting. Combines specifically chosen and proven casting materials to provide an intimate comfortable close fit and optimized healing environment for a costeffective treatment. Its standardized technique simplifies the implementation of the pressure offloading Gold Standard in the treatment of diabetic foot ulcers.

51 Indications Non-infected diabetic and neuropathic foot wounds Charcot joint injuries Post-op immobilization following deformity reconstruction Features and Benefits Increased patient compliance Optimized healing environment Standardized technique Convenient all-in-one kit Cost-effective Latex Free

52 TCC-EZ TCC-EZ is a unique and versatile total contact cast system designed to reduce application time while providing improved healing rates for the diabetic foot ulcer and increased stability and comfort for the patient. Offers a one-piece, roll-on, light weight, woven design that is faster and easier than traditional total contact cast systems. Can be applied in under 10 minutes Enforced Patient Compliance Takes less than ¼ of the amount of time of traditional total contact cast systems Requires minimal training time Lightweight woven design offers a more comfortable fit Allows for customized fit on every application

53 The Kit

54 Compared to traditional Total Contact Casts 4 times as many patients were casted in clinics using than traditional total contact cast systems Enforced Patient Compliance Significantly fewer signs of infection Outcomes are comparable or better than traditional total contact cast system

55 The Total Contact Cast can cut amputation rates in half Total Contact Cast patients have half the amputation rate (Non-Total Contact Cast 5.2%, Total Contact Cast 2.2%) The most used method of off-loading employed by practitioners is the least effective (Surgical shoe) Only 3.7% of eligible Diabetic Foot Ulcers received a Total Contact Cast
