The present invention is directed to a device that permits a permanent aperture to be formed in a wall, or other partition, of an implantable medical device. The present invention maintains the continuity and fluid-retaining properties of the implantable medical device by providing a breachable barrier material fully covering an opening delimited by a deformable framework. The invention is accessed with conventional interventional surgical instruments that disrupt and displace the barrier material. Following disruption of the barrier material, the opening is enlarged with surgical instruments to form a permanent framed aperture in the wall of the implantable medical device. The permanent framed aperture provides fluid communication across the wall of the implantable medical device.
L'invention concerne un dispositif qui permet de former un orifice permanent dans une paroi ou toute autre cloison, dans un dispositif médical pouvant être implanté. L'invention concerne, de plus, le maintien des propriétés de continuité et de retenue de liquide du dispositif médical implantable, obtenu grâce à l'utilisation d'un matériau barrière pouvant être ébréché et qui recouvre entièrement un orifice délimité par une infrastructure déformable. Le dispositif de l'invention est destiné à des instruments chirurgicaux d'intervention classiques qui détruisent ou déplacent le matériau barrière. Après destruction dudit matériau barrière, l'orifice est élargi au moyen d'instruments chirurgicaux, de façon à former un orifice formé de manière permanente dans la partie du dispositif médical implantable. Ledit orifice formé de manière permanente permet une communication fluidique à travers la paroi du dispositif médical implantable.
