A deployment system (10) for an endoluminal device. The deployment system (10) includes a confining sheath (12) placed around a compacted endoluminal device (14, 15). A deployment line (16) is provided in the system that is an integral extension of the sheath (12). As the deployment line (16) is actuated, the sheath (12) retracts from around the compacted endolurninal device (14, 15). As the sheath (12) retracts from around the endoluminal device (14, 15), material from the sheath may be converted into deployment line (16). Once the sheath (12) is retracted from around the compacted endoluminal device (14, 15), the endoluminal device (14, 15) expands in configuration and repairs vascular or cardiac structures of an implant recipient. Any remaining sheath material (12) is removed from the implantation site along with the deployment line (16). The deployment system (10) also includes an endo-prosthesis mounting member (18) placed between the endoluminal device and an underlying catheter (19). The endo-prosthesis mounting member (18) serves to cushion and retain the endoluminal device (14, 15) when constrained by the sheath (12) and may assist in expansion of the endoluminal device (14, 15) when unconstrained by the sheath (12).

L'invention concerne un système de déploiement d'un dispositif endoluminal. Ce système de déploiement comprend une gaine de confinement placée autour d'un dispositif endoluminal compacté. Ce système comprend une ligne de déploiement qui est un prolongement intégré de la gaine. Lorsque la ligne de déploiement est actionnée, la gaine est retirée de sa position autour du dispositif endoluminal compacté. Lorsque la gaine est retirée de sa position autour du dispositif endoluminal compacté, le matériau de la gaine peut être converti en une ligne de déploiement. Une fois que la gaine a été retirée de sa position autour du dispositif endoluminal compacté, la configuration du dispositif endoluminal se déploie et celui-ci répare des structures vasculaires ou cardiaques d'un receveur d'implant. Tout matériau de gaine restant est enlevé du site d'implantation conjointement avec la ligne de déploiement. Le système de déploiement selon l'invention comprend également une élément de montage d'endoprothèse placé entre le dispositif endoluminal et un cathéter sous-jacent. L'élément de montage d'endoprothèse sert de coussin et retient le dispositif endoluminal lorsqu'il est serré par la gaine. De plus, l'élément de montage favorise l'expansion du dispositif endoluminal lorsque la gaine se desserre.
