a world first for the French Lattice Medical

Implantation of the Matisse prosthesis by Prof. Nemsadze’s group on the Institute of Medical Oncology (picture credit: Lattice Medical)

2022 is unquestionably a milestone yr for medical 3D printing. What might need appeared hypothetical or out of attain just some years in the past is occurring proper earlier than our eyes. The promise of generative and customized drugs because of this tailored expertise is more and more changing into a actuality for sufferers. After the American 3DBio Therapeutics efficiently carried out the first transplant of a bioprinted ear on a 20-year-old lady, one other world premiere, this time with a French accent, passed off.

Two months after the launch of its medical trialsLille nugget Lattice Medical, formalized yesterday the primary implantation of its 3D printed breast prosthesis in a affected person. The primary in an extended sequence, the operation passed off on July 12 on the Institute of Medical Oncology in Tbilisi, capital of Georgia. A feat stuffed with promise achieved by Pr Gia Nemsadze and his complete group, and within the presence of the co-founders of Lattice Medical, Pr. Pierre Guerreschi, Pr. Philippe Marchetti, (each PUPH on the Lille College Hospital) and Mr Julien Payen .

The primary affected person to learn from this printed and bioresorbable prosthesis is a 62-year-old lady affected by breast most cancers. The surgical intervention lasting an hour and a half, in comparison with three to 12 hours for a traditional reconstruction by flap, allowed the belief of the mastectomy, instantly adopted by the breast reconstruction. Two months after the operation, Lattice Medical reviews full therapeutic and a really wholesome affected person.

If you do not know her but, medical mesh is a French start-up that has taken benefit of the nice freedom of type of 3D printing to develop a breast prosthesis that may adapt completely to the morphology of the affected person. For this, the corporate has developed a tool made up of two elements: a three-dimensional assist impressed by the 3D properties of Calais lace, and a 3D printed dome serving as a information for cell development.

“Aesthetic standards of the reconstructed breast, high quality of life and affected person satisfaction shall be assessed”

Precept of operation of MATISSE (Regeneration of adipose tissue then resorption of the implant)

A scanner or an MRI carried out on the affected person, permits the belief of a tailored prosthesis completely conforming to her morphology. As soon as the system is implanted, a pedicled and vascularized flap of fats is positioned inside. The expansion of adipose tissue can then happen till the tissue chamber is totally stuffed.

Printed from a polymer derived from polylactic acid, this 3D implant is absolutely degradable. Beneath the impact of the assorted organic reactions produced by the physique, the system finally ends up fully disappearing after 18 months.

” Synchronously, the biomaterial constituting the TEC (tissue engineered chamber) is absolutely resorbable. Sufferers shall be adopted commonly for 12 or 24 months. “Specifies Lattice Medical. ” Flap development and TEC resorption shall be measured by MRI. The aesthetic standards of the reconstructed breast, the standard of life and the satisfaction of the sufferers shall be evaluated. »

The explanation why this resolution developed by Lattice Medical is especially progressive in comparison with the present one, is {that a} single operation (particularly very quick) is sufficient, and it permits a pure reconstruction of the sufferers’ breasts. Extra conventional reconstruction strategies reminiscent of flap reconstruction are operations identified to be significantly heavy, but in addition very pricey for the well being system. A step stuffed with promise due to this fact, and a supply of hope for the 22,000 French ladies who should endure a mastectomy every year following breast most cancers.

Together with a recruitment interval of 8 months, the medical research shall be unfold over three years. Its protagonists plan to incorporate 50 sufferers, in Georgia, France and Spain in 8 facilities. It is going to be coordinated by Pr Pierre Guerreschi working within the cosmetic surgery division of the Lille College Hospital.

Captivated with 3D printing, I unfold the nice phrase to democratize and open this expertise to as many individuals as doable. Information, purposes, interviews… I work to indicate people and professionals the complete potential of this revolutionary device. Firms, fablabs, distributors, associations, designers, I additionally wish to create by way of this web site an emulation between the totally different actors on this subject.
