La principal motivació d'aquest treball va ser analitzar la viabilitat del procés de fabricació de stent actual per produir els nous stents bioabsorbibles (SBA), així com estudiar noves maneres de fabricar-los. El tall làser de fibra (TLF) ha estat seleccionat perquè és el procés de fabricació actual per stents i L´impressió 3D (I3D) perquè té la capacitat de processar diferents tipus de materials per a aplicacions mèdiques i els seus aspectes econòmics. Stents ha estat seleccionat per ser un dels dispositius mèdics més implantats del món. La tesi es centra en la millora dels processos de fabricació de stent, establint relacions entre els paràmetres del procés i els aspectes clau de stent, precisió, propietats mecàniques i propietats mèdiques i reduir els costos derivats d'aquest procés de fabricació

Mastectomy is one of the most common way to treat breast cancer, it consists in the removal of breast tissue to remove tumor cells. This surgical act causes a consequent loss of tissue and can then be followed by a breast reconstruction operation to fill in the missing volume. Implant based or autologous fat grafting (fat flap or lipofilling) are some of breast reconstruction method, however they all have advantages and drawbacks. Tissue engineering chamber (TEC) using fat flap from the patient’s own tissue could be a promising solution to restore large volume of mature and vascularized adipose tissue and a therapeutic alternative to current breast reconstruction techniques.The main objective of this thesis it to improve TEC by using additive manufacturing and bioabsorbable polymers. The use of bioresorbable thermoplastic polymers eliminates the need for a second surgery, which would consist of removing the implant after breast reconstruction. In addition, using 3D printing to manufacture the TEC will allow patients to be offered tailor-made implants adapted to their morphology and therefore improve the aesthetic aspect of the reconstruction.The study first focused on the choice of an additive manufacturing process and a sterilization method for the development of the implant to minimize the degradation of the selected biomaterials. Fused Filament Fabrication (FFF) as well as ethylene oxide sterilization were chosen as means of producing the final sterile device. An in vitro degradation study was then carried out to determine the resorption profiles of PLGA and PLCL. Finally, an in vivo study was carried out on a rat model which enabled us to validate the concept of 3D-printed bioabsorbable TEC. The two selected polymers were therefore shown to be compatible with the tissue engineering chamber reconstruction process and thus allowed the growth of the fat flap over time within the TEC

The treatment of soft-tissue infections, osteomyelitis, and acute or chronic septic arthritis is a lengthy process that involves repeated surgical procedures and the systemic administration of antibiotics for at least 6 weeks to 3 months. Poor diffusion of antibiotics into bones and joints requires high doses given parenterally for long periods. At present, the antibiotic vector most widely used in humans with bone or joint infections is polymethylmethacrylate. Because PMMA is not bioabsorbable, multiple surgical procedures are required to eradicate infection. Furthermore, PMMA does not release its full antibiotic load over time and may yield local antibiotic concentrations lower than the minimal inhibitory concentration of the causative organism, thereby promoting the emergence of resistant strains. The objective of our work was to develop a fully bioabsorbable polymer capable of ensuring the prolonged and efficient release of its antibiotic load, thus improving the management of bone and joint infections. The specifications for the polymer included the release by the matrix system of 1-2 mg of gentamicin per day and per gram of mixture over more than 10 days. Other specifications were appropriate physical characteristics, a drug release rate sufficient to ensure optimal treatment safety, and ease of implantation. The polymer was also to be bioabsorbable, i.e., subject to degradation into fragments capable of being eliminated naturally by the body. High-molecular weight PLA50P, Poly(D,L-lactic acid) was created and found to meet these specifications. Use of this polymer as large particles (0.5 to 1 mm) limited the initial burst phenomenon. A gentamicin-PLA50P mixture was obtained by compression of the two components prepared in powder form. The antibiotic load was set at 20% to limit the initial burst. The polymer can be sterilized by gamma irradiation, which has no effect on drug release characteristics.In vitro kinetic studies of gentamicin release by the polymer showed a peak on day 12 followed by a plateau that lasted until day 63. After 3 weeks, the cumulative amount of gentamicin released in vitro was 54% of the total amount loaded onto the polymer. In vivo gentamicin concentrations measured in situ were 5.1 µg/mL on day 3, 1.9 µg/mL on day 7, and 0 µg/mL on day 35, when the polymer was no longer visible to the naked eye. Thus, both in vivo and in vitro, gentamicin was released in concentrations greater than the MIC of the microorganism, for longer than 3 weeks.To test the gentamicin-loaded polymer, we created a rat model of periosteal infection. Rats aged 10-12 weeks received two 100 mL injections of methicillin-susceptible Staphylococcus aureus collected from animals, into the middle third of the hind leg, in contact with the bone. Treatment with gentamicin-loaded PLA50P proved superior over parenteral administration of an equivalent gentamicin dose, consistently reverting the bacteriological cultures to negative. We then created a rabbit model of septic arthritis. A doe weighing 4 kg received an add intraarticular injection of 1 mL of a solution containing 103 cfu/mL of a methicillin-sensitive S. aureus strain collected from another rabbit. Gentamicin-loaded PLA50P treatment induced a highly significant drop in the intraarticular bacterial load (by 3-4 log10), whereas standard systemic gentamicin therapy failed to significantly diminish bacterial counts comparatively to the untreated controls. Thus, gentamicin-loaded PLA50P diminished the bacterial load by 3 log10 comparatively to the other groups and allowed eradication of the infection in 2 of the 6 rabbits.In sum, gentamicin-loaded PLA50P (i) ensures the stability of the antibiotic; (ii) is available as a stable powder; (iii) ensures the prolonged release of gentamicin over several weeks; (iv) produces a limited burst effect; (v) exhibits very good biotolerance; (vi) and is more effective than standard antimicrobial therapy
Duval, Charlotte. « Elaboration de copolymères biorésorbables pour endoprothèse ». Thesis, Vandoeuvre-les-Nancy, INPL, 2011. http://www.theses.fr/2011INPL018N/document.
This work describes the synthesis of biodegradable copolymer to design a bioabsorbable endoprosthesis. Lactide and glycolide-based copolymers were synthesized by ring opening polymerization. Experimental conditions were chosen to produce controlled structures. The study of mechanical properties was performed in dry and wet states. During the tensile experiments, the effect of strain rate was noticed and some characteristics parameters were determined. Hydrolytic degradation of materials was fast and revealed a heterogeneous mechanism. Addition of acidic molecules for plasticizing increased the degradation rate of the copolymers.Mechanical properties and degradation of the PDLGA copolymers are indeed in good agreement with the specifications of this biomedical application
