The Motiva Flora® Tissue Expander is the first tissue expander made with an integrated Radio Frequency Identification (RFID) port. An air wound coil, where the RFID technology lies, is embedded in the needle stop. The said coil is activated externally to determine the exact location of the inject using the LED indicators on the Port Locators. The RFID port has no magnets, which allows Magnetic Resonance Imaging (MRI) during the expansion process.

Traditional tissue expanders use magnetic ports. These magnetic ports cause significant safety issues such as valve dislodgement and burning sensations. Also, it causes substantial signal loss and distortion of MR images, making it “MR Unsafe”.


For cases of post-mastectomy, a follow-up with full functional imaging capabilities is a vital part of its management. With Motiva Flora® Tissue Expander, surgeons can now monitor possible complications with the help of imaging tools with high sensitivity and specificity. It offers prospective diagnostic benefits for patients undergoing MRI.

Traditional magnetic ports produce large distortions of T1 (a) and T2 (b) in weighted axial MR images, hindering correct assessment, even in the opposite breast.

Motiva Flora® Tissue Expander that uses the RFID port does not generate distortion of T1 (a) and T2 (b) in weighted axial MR images.


The Motiva Flora® Tissue Expanders have orientation lines made with a radiopaque blue material. It helps in the correct positioning of the device during implantation and identifies possible rotation post-implantation during an X-ray procedure.


Traditional tissue expanders using magnetic ports distort Computerized Tomography (CT) images, which create more difficulty in planning treatments. The Motiva Flora® Tissue Expander decreases artifacts in CT scans as it is not affected by exposure to up to 50 Gy radiation.

The Motiva Flora® Port Locator has a radiofrequency identification (RFID) wireless system that emits radio waves. It receives signals from the RFID coil located inside the needle that stops to communicate its location.

The Motiva Flora® Tissue Expander contains passive RFID transponder that provides an Electronic Serial Number (ESN) that is unique to each device. This ESN can be matched to a database of internal records for traceability of relevant information (serial and lot numbers reference number, volume, size, projection, model, surface, type, manufacturing date).
