Motiva Flora® Tissue Expander (two-stage anatomical saline fill) is the first device of its kind that comes with an integrated Radio Frequency Identification (RFID) port. An air wound coil containing RFID technology embedded in the needle stop is activated externally, allowing surgeons to achieve an exact localisation of the injection site through an LED indicator on the ergonomic port Locator. It has no magnets, allowing for MRI scanning during the expansion process. Traditional tissue expanders have magnetic ports that create significant safety issues, substantial signal losses, and distortion on MR images and are labeled “MR Unsafe”.

An extracellular matrix with superior strength that provides a natural anchoring effect, removing the requirement to suture in place. The ultra-thin, meshed matrix is gently purified to maintain the natural ‘pro-heal’ properties in the bi-layer bovine pericardium. All of these qualities combined provide the ultimate solution for consistently reliable results. QUICK – rapid hydration and anterior coverage of the implant in minutes, without the need for time-consuming adaptation. BIOSHIELD GRIP – the natural presence of a high friction, fibrous exterior provides a natural anchoring effect, avoiding the requirement for suturing the construct to the chest wall in most cases. Whilst also being an ideal environment for cell revitalisation, leading to rapid cell integration. RAPID INTEGRATION – non-crosslinked purification process preserves ‘pro-heal’ elements which promote cell proliferation and migration. The volume of biological mass present is also up to 50% less than alternatives, further promoting the speed of cell ingrowth. SUPERIOR STRENGTH – a naturally strong raw material that enhances the Surgeon’s control of the implant within the mastectomy pocket and provides consistent aesthetic results, whilst also enabling easy handling and positioning of the matrix around the implant.

Exa-flex is a unique bi-layer membrane obtained through the processing of bio-secure bovine pericardium. Developed exclusively for use in breast reconstruction surgery, the Exa-flex membrane is processed using a proprietary process which allows the extraordinary characteristics of the natural pericardium to be preserved. Exa-flex ensures a rapid integration with each of the two layers carrying out a specific task in the integration process; Fibrous layer: is highly porous, it accepts the cells and together with the matrix components collaborates with cytokines and growth factors for immediate regeneration and early neoangiogenesis. Compact layer: gives support to the matrices. The Exa-flex Pocket for elective use in immediate pre-pectoral breast reconstruction is designed to revolutionise the surgical procedure. When the membrane is rehydrated it allows anterior coverage of the implant in around 60 seconds, without the time-consuming adaptive procedures which involve surgical delays, risks of accidental damage to the breast prosthesis and greatly reduces the relative risk of contamination. The pre-formed mesh is re-hydrated, with the smooth side (intended to receive the prosthesis) facing the operator. The anterior surface of the implant is placed on the membrane, by drawing the double purse-string, the “petals” are fixed in a few seconds to the back side of the prosthesis. By tying off the purse-strings; thanks to the drapability of the material and to the mesh configuration, The Exa-flex Pocket fully covers the anterior surface and partially the posterior surface of the prosthesis without any unnecessary excess material. The assembly is ready to be positioned, even without the need of sutures for fixing to the chest wall; the high superficial friction coefficient provided by the fibrous side in contact with the skin flap ensures considerable grip.

TIGR Matrix - strong when needed, gone when you don't. The ideal matrix material for breast reconstruction and support. TIGR Matrix is the world's first long-term resorbable, 100% synthetic mesh, made from materials that have been in clinical use since the 1970's (lactide, glycolide, trimethylene carbonate). It's unique technology consists of dual degradation and full resorption. Over time TIGR Matrix degrades and the support load is gradually transferred to the newly regenerated tissue during the remodeling phase, resulting in new supportive and protective functional tissue. TIGR Matrix is rapidly integrated into the surrounding tissue by deposition of new collagen and the formation of new blood vessels. Specifically designed for soft tissue repair and used by surgeons world-wide in reconstructive surgery. TIGR Matrix is strong whilst remaining soft and pliable, ideally when preforming implant based breast reconstruction, either sub-pectoral or pre-pectoral and for support to breast tissues in secondary breast augments and mastopexy patients. The untwisted multifilament fibers allow new tissue to integrate fully through the porous structure as well as in-between each fiber. Clinical data shows extremely low complication and implant loss. TIGR Matrix is easy to use and handle and can be cut and trimmed where required. The multifilament structure allows suturing even into the corners.

B-Lite® the first and only Lightweight Breast Implants in the world. Up to 30% lighter than conventional implants – B-Lite® implants reduce the stress and strain on the breast soft tissue, and maintain the shape and appearance of the breast in the long term. The uniquely lightweight B-Lite® series has revolutionised the world of breast implants and is considered one of the most significant developments in the industry over the last 30 years. To achieve this, B-Lite® combine proven materials with breakthrough technology: the standard silicone gel filling is enhanced with special microspheres and is designed to reduce the effects of gravity. The result is an implant that combines comfort with sustainable aesthetics; less ptosis, atrophy, rippling and patient discomfort. When compared to conventional implants, patients with B Lite implants also experienced less post-operative surgery pain, required less analgesia, had shorter recovery times and faster return to normal activities. The microsphere design also enables improved imaging on mammography and ultrasound. The B-Lite® series implants have been available since January 2019 and are currently manufactured in round and anatomical shapes with a microtextured POLYtxt® surface.
