What Is SureDerm™?

SureDerm™ is acellular human dermis, which is intended for the repair or replacement of damaged soft tissue.
SureDerm™, can be used as a substitute for autograft with its equal usage, effect and safety while it solves donor site trauma followed by autograft.

SureDerm .... is processed human skin by a special process of high technology. Main purpose of this technological process is to be easily transplanted without rejection by eliminating the Immune response.
When heating completed, SureDerm™eventually becomes the patient's own tissue.

Technology

Human skin has a highly complicated structure of epidermis which contacts first to the external environment and dermis which is 1-2mm in thickness and located in lower layer of epidermis.

Dermis contains connective tissue including a complex matrix of collagen, elastin, laminin of bioactive protein and blood vessels so that it conducts very important role to make human skin resilient and functional. SureDerm™ remains this biological dermal matrix from donated human skin while it keeps no cells regulating the immune response. Therefore SureDermllol can be transplanted smoothly without any rejection and serves as tissue reconstruction. The main process to make these possible Is decellutarization and lyophilization using a patented technology of Hans Biomed Corp.

SureDerm™ for Graft

The necessary materials for the technique:
two sterile dishes, rehydration fluid of at least 100ml sterile saline, sterile forceps.

The Rehydration

• Soak the tissue completely into at least 5Oml of rehydration fluid sterile normal saline when SureOerm"' is 21Cm) or smaller and at least 100ml when over 21cm for about 10 minutes before use.
• Treat the wound clean to avoid no active bleeding.
• Place the dermal side of graft on to the wound bed.

Set the dermatone for the thinnest 0.02mms autograft and first secure SureDerm™ then place autograft and secure this one as welt using sutures or staples.

• The correct orientation of dermal side.
• Drop a blood to both sides of the graft and rinse with rehydration solution.
• The dermal side will be ready to absorb blood, while the basement membrane appear pink.

Dressing the wound

• 1st dressing: Gauze impregnated with petrolatum, gentamicin or triple·antibiotic oinment.
• 2nd dressing: Gauze wrap damped with saline.
• 3rd dressing: Dry gauze wrap.
• Change dressing: To ensure optimum engraftment, you can remove the innermost layer of dressing on day 5-7, the outer layers of the dressing may require 2·3 days changing to prevent accumulation of fluid and bacteria.
  SureDerm™ for Implant

After full rehydration (same as SureDermu™ for graft), shape the tissue rolled or folded to the desired thickness.
