The society

AnatomikModeling designs and develops custom-made implants, that are perfectly fitting each patient’s anatomy.

These implants are used to compensate for a congenital deformity or trauma, in particular for pathologies such as Pectus Excavatum (funnel chest or sunken chest), Poland syndrome (complete or partial absence of the pectoralis muscle) or calf atrophy.

Body

Activity

AnatomikModeling est le fruit de 10 ans de recherche et développement avec le Service de Chirurgie Plastique, Reconstructrice et Esthétique du CHU de Rangueil et le Service de Chirurgie Thoracique de l'Hôpital Larrey à Toulouse. Cette collaboration a permis de mettre au point une technologie particulièrement innovante de conception assistée par ordinateur (CAO) d'implants 3D personnalisés et de développer un mode d'intervention peu invasif pour la pose de ces implants.

AnatomikModeling mène une recherche continue pour trouver des solutions innovantes à des pathologies aujourd'hui mal traitées, en s'appuyant sur les technologies 3D. Plusieurs projets d'innovation sont actuellement à l'étude, en particulier dans le domaine du Maxillo-facial et de la Pneumologie.

Enfin, AnatomikModeling propose aux professionnels de santé la modélisation de l'impression 3D de modèles anatomiques pour la préparation d'interventions complexes.

 

Technology

Computer-aided designing (CAD)

Computer Aided Design of a Pectus Excavatum Implant

  • From hospital patient scan a 3D virtual copy of each patient’s body, each tissue being separated (bones, muscles, skin, cartilages…). These 3D reconstructions require complex mathematical algorithms for medical imaging processing.
  • The implant is then virtually designed on each patient’s 3D-scanned body. Each implant is unique and perfectly fitting each patient’s anatomy. The result is controlled and refined with the direct participation of the surgeon in charge.

Manufacturing of the silicone implant

  • Once the 3D model is designed, it is sent in rapid prototyping to get a perfect anatomical copy of the implant. This prototype will be used to make the casting mould.
  • Our partner SEBBIN then proceeds to the final manufacturing of the implant according to the ISO standards in force.
  • The implants are made in NuSil medical polymerised silicone also called silicone rubber and not as a silicone gel as it is the case for breast implants. There is therefore no risk of implant rupture or appearance of retractile fibrous shells, the implants are placed for life.

Background

1993: Development of the first silicone implant from a plaster mould of the thorax at the Toulouse University Hospital and the first surgery on a sunken chest using a custom‑made implant.

2008: First implant made from a computerised reconstruction of the thorax as part of a medical thesis completed at the Toulouse University Hospital.

2010: Start of the collaboration between IMA Solutions and Pr Chavoin to optimise computer‑aided design of custom‑made implants. Sebbin Laboratory in charge of manufacturing these implants.

2011:  Already 200 implants placed. New reference thesis on the funnel chest comparing techniques (Lasserre Prize award).

2013: Managing prototypes using machining CAD images

2015: Creation of AnatomikModeling, specialising in custom‑made implants for chest deformity, Poland Syndrome and muscle deficiency. Deployment of the surgical technique in Europe through a network of referral surgeons

2016: World premiere of the placement of a custom-made tracheobronchial stent at Toulouse University Hospital

More than 1300 patients already treated with custom made implants, among them almost 1000 Pectus Excavatum (September 2019)
