A method for making sterile suture packages employs a frame assembly line, a sterilization line and a blanker/cartoner line. A web of foil is advanced in a series of movements through the frame assembly line to assemble a frame containing needle-suture assemblies in a plurality of cavities in the frame, the frame having top and bottom aluminum foils with heat seal coatings on their facing surfaces. The cavities are formed in the bottom foil of each frame by a combination of pressurized air and mechanical plugs which are forced against the bottom foil and an underlying die having recesses for defining the cavities. A blanking operation following sterilization and sealing separates individual packages, each containing one needle-suture assembly, from the frame. The packages are then conveyed by belts through inspection stations and reoriented for loading into shipping cartons.

Méthode pour conditionner des ensembles à suture stériles comprenant l'assemblage de plateaux-compartiments, la stérilisation et le découpage/encartonnage. Une feuille d'aluminium en continu passe en une série de mouvements sur un cadre de façon à former un plateau à plusieurs compartiments destinés à recevoir les ensembles suture-aiguille; ainsi le dessus et le dessous du cadre sont recouverts d'une feuille d'aluminium dont la surface exposée est enduite d'un revêtement thermoscellable. Les compartiments formés dans la feuille d'aluminium du fond sont obtenus par l'utilisation d'air pressurisé, de bouchons forcés mécaniquement contre la feuille de fond et de matrices sous-jacentes visant à structurer les compartiments. L'opération de découpage effectuée après la stérilisation et le scellage sépare les paquets contenant chacun un ensemble suture-aiguille, du plateau-compartiments. Les paquets sont ensuite acheminés au moyen d'un système à bandes transporteuses aux postes d'inspection et réorientés pour être chargés dans des cartons d'expédition.
