Abstract
(EN)
A method is provided of making a bioabsorbable appliance that includes selecting a first bioabsorbable polymer having a first glass transition temperature above about room temperature and selecting a second bioabsorbable polymer having a second glass transition temperature below about room temperature. The method also includes combining the first and second bioabsorbable polymers to form a combination and subjecting the combination to a pressure. Additionally, the method includes injecting the combination into a mold in a shape of the bioabsorbable appliance and removing the bioabsorbable appliance from the mold. The method may include adding a bioactive agent to the combination. The steps of combining the first and second bioabsorbable polymers, subjecting the combination to pressure, and injecting the combination into a mold, may be performed at about room temperature. The bioabsorbable appliance may be a stent, a catheter, a guide wire, a balloon, filter, a vena cava filter, a stent graft, a vascular graft, an intraluminal paving system, or an implant. A medical appliance is provided that includes a polymer combination including first and second bioabsorbable polymers formed in a shape of the medical appliance.

La présente invention a trait à un procédé pour la fabrication d'un dispositif biorésorbable comprenant la sélection d'un premier polymère biorésorbable ayant une première température de transition vitreuse supérieure à la température ambiante et la sélection d'un deuxième polymère biorésorbable ayant une deuxième température de transition vitreuse inférieure à la température ambiante. Le procédé comprend également la combinaison des premier et deuxième polymères biorésorbables pour former une combinaison et la soumission de la combinaison à une pression. En outre, le procédé comprend l'injection de la combinaison dans un moule sous la forme du dispositif biorésorbable et le retrait du dispositif biorésorbable du moule. Le procédé peut comprendre l'ajout d'un agent bioactif dans la combinaison. Les étapes de combinaison des premier et deuxième polymères biorésorbables, de soumission de la combinaison à une pression et d'injection de la combinaison dans un moule, peuvent être réalisées approximativement à la température ambiante. Le dispositif biorésorbable peut être une prothèse endovasculaire, un cathéter, un fil-guide, un ballonnet, un filtre, un filtre de veine cave, un greffon d'endoprothèse, une endoprothèse vasculaire, un système de revêtement intraluminal, ou un implant. L'invention a également trait à un dispositif médical comportant une combinaison à base de polymères comprenant des premier et deuxième polymères biorésorbables sous la forme d'un dispositif médical.
