Designed for Reconstructive Plastic Surgery, the Exashape membrane is processed through a proprietary method that maintains the unique qualities of natural bovine pericardium¹.
Exashape Bioshield pocket guarantees fast integration times with cell ingrowth², minimal inflammation³ and negligible serum production, while maintaining remarkable mechanical properties¹.
The two layers perform a specific task in the integration process.
Fibrous layer: highly porous, it welcomes cells and, together with the matrix components, allows cytokines and growth factors to trigger the immediate revitalization process and early neoangiogenesis [2].
Compact layer: it is quickly repopulated by fibroblasts and VEGF². After implantation, there is no accumulation of inflammatory or giant cells. It is the part that provides the most solid structural support.
The bilayer membrane undergoes a 3-stage process of revitalization by endogenous connective tissue.
During implantation, the collagen matrix absorbs the blood and the revitalization process begins immediately, characterized by a controlled and short-lived inflammation phase with considerable neoformation of vessels [2,3].
Fibroblasts reactivate collagen by triggering the ingrowth of new vessels, which provide the metabolic needs. At this stage of the reparative process, cell proliferation prevails, which targets the growth of new tissue [2].
The actual remodeling phase begins its course and is the result of the precise balance in the synthesis of collagen, which becomes an integral part of the tissue [3].
The cell-friendly process preserves the active elements in the repair process within the membrane: proteoglycans, hyaluronic acid, fibronectin, elastin and of course, native collagen. They represent a natural reservoir of bioactive factors, which participate in the revitalization process by controlling inflammation while promoting cell proliferation and migration [2]. We limit the amount of biological mass implanted (up to 50% less, due to lower thickness of pericardium compared to dermis) promoting integration even in cases of poor blood supply, while maintaining the highest bio-mechanical performance [1,4].
The membrane’s shape is conceived for anatomical and round implants. A perfect support is achieved by tightening the petals so that wrinkle-free tailor-made protection for each implant profile or volume, without waving or wrinkling which, as with thick matrices, can be sometimes perceptible in thinner patients.
Less than 0.6 mm thick, this membrane helps to minimize the foreign body response by facilitating rapid integration and faster tissue regeneration. The overall biological mass is 50% less than other membranes dermal based.
The meshed scaffold design optimizes fluid drainage preventing accumulation. The perfect balance in the proportion between cut-outs and collagen best support timing of regeneration.
Bioshield pocket 3D adapts more effectively to the implant and it shields only where needed: the dermal flap interface. This way foreign body reaction is minimaized, and also healing process is not overloaded with unnecessary effort to remodeling exceeding biomass.
The new pre-shape design facilitates a rapid, touchless assembly procedure that can be completed in less than 1 minute minimizing the risk of contamination and ensuring a sterile environment far optimal surgical outcomes.

A patented design mesh that improves surgical procedures.
Bioshield Pocket® serving as an elective option for immediate PrePectoral breast reconstruction for the protection of the implant/tissue interface
Bioshield Pocket® aims to streamline surgical procedure as the rehydrated membrane allows for quick wrapping of the implant without the need for complex tailoring procedures, reducing intra-operative delays, lowering risks of implant damage and potential contamination
After running the threads through the “petal” holes, the mesh is rehydrated in the sterile tray, with the smooth side facing the operator. Subsequently, the anterior surface of the implant is positioned on the membrane within a few seconds. The ‘petals’ are tightened to the implant’s posterior side creating a “purse string” assembly.
Due to the meshed pattern and rough external surface, Bioshield Pocket® offers a secure grip on the chest wall ensuring that the implant remains in place during and after surgery.
The high drapability allows the membrane to follow the silicone implant shape with no “dead spaces” or wrinkles
