TECHNOLOGY

Lattice Medical is a biomedical start-up that was launched in October 2017
Patented 3D technology developed with CHU Lille-France that allows adipose tissue to naturally regenerate

Breast cancer touch 1 in 8 women in the world In 40% of cases, mastectomy is the usual treatment followed by chemotherapy or radiotherapy
Only 14% of women receive reconstructive surgery
01
08
Reconstruction procedure offered are:
silicon prosthesis, autologous fat tissues grafting by microsurgical technics (DIEP) or non-vascularise transfer (lipofilling).

These methods show different issues such as multiple surgical procedure, complications and costs for healthcare system, limiting the availability for patients.
02
08
LATTICE MEDICAL, valorising 6 research years from CHU Lille, comes up with an innovative technical solution combining the advantages of current techniques, thereby simplifying the process and making it more accessible and less expensive: a 3D printed bioabsorbable implant called MATTISSE.
03
08
The technology involves the use of autologous adipose tissue as a base, and then combines this with a 3D printed absorbable implant, thereby making it possible to get the desired size with just one operation. This implant helps the patient’s fat cells regenerate.
04
08
MATTISSE is made up of two 3D printed bioabsorbable parts: the first, inspired by Calais laces, provides support for the fat, and the second is a shell giving the volume and the shape reconstruction.

The use of 3D printing makes it possible, using MRI or CT-scan images, to design a personalised implant to restore former breast.
05
08
Autologous fat tissues are placed on the support material. It helps guide tissue reconstruction during 4 to 8 months. Meanwhile, the bioabsorbable implant will slowly degrade, until full resorption in one year. The breast is thus entirely rebuilt by the patient’s tissues, without introducing any foreign bodies.
06
08
LATTICE MEDICAL’s ambition is to make and commercialize the implant for reconstruction and plastic surgery markets by 2023. The product is in the pre-clinical development stage and be tested in a first clinical breast reconstruction trial in 2021.
07
08
The breakthrough innovation that Lattice Medical has developed was made possible by combining different skillsets in the textile materials industry, including through UP-tex, in connection with the medical and university team of CHU Lille and of Lille University.

Since January 2017, Lattice Medical has been in incubation at Eurasanté and receiving financial support from the Hauts-de-France region as well as from BPIFrance.

APPLICATIONS

THE MAT(T)ISSE BIOPROTHESIS:
A BIO-RESORBABLE TEC
(TISSUE ENGINEERING CHAMBER)

RESORBABLE CHAMBER

Designed and made
with 3D printed biomaterials

Adapted to the individual morphology of patients

Fully degrades
in a year

PATIENT AUTOLOGOUS ADIPOSE TISSUE GRAFTING

Vascular adipose flap tissue inlaid
over the Tissue Engineering Chamber (TEC)

Guided tissue
reconstruction

Regenerates patients’
adispose cells

The desired size is reached after just one surgery: breasts are entirely reconstructed by the patient’s tissues, and no foreign bodies are introduced.

SUBCUTANEOUS TISSUE
AND FACIAL RECONSTRUCTION

Lattice Medical also provides solutions for improving tissue engineering and regenerative medicine using 3D-printed bio-resorbable scaffolds.

Following surgery, serious burns, chronic wounds, and accidents, traumatized soft tissue needs to be repaired.

In collaboration with CHU Lille, Lattice Medical provides product design, R&D services, and various solutions for soft tissue engineering and regeneration. Alongside textile manufacturing partners, we develop textile matrixes (including Calais lace ones) that are obtained through the Leavers method.

Lattice Medical offers sub-licensing R&D contracts to manufacturers and provides pre-clinical proof-of-concept studies.

SOFT TISSUE RECONSTRUCTION PLATFORM

A new era in medical application development

Thanks to its integrated platform, Lattice Medical is able to offer innovative solutions and the opportunity for biomedical projects to explore new technological landscapes. Lattice Medical is helping manufacturers in the medical procedure industry with their transition towards 3D technology.
Lattice Medical is developing the first ISO 13485 production in clean room with 3D printing for designing personalized implantable resorbable medical devices.
This unique platform is endowed with new 3D printing and extrusion technology that is able to produce prototypes, pre-series and industrial series for R&D trials, pre-clinical and clinical studies at extremely low particular pollution levels.
