Medical graft component and methods of installing same

摘要

Apparatus for securing an axial end portion of a tubular graft conduit in a lumen of a patient's existing tubular body organ structure via an aperture in a side wall thereof is disclosed. An anchor device is configured for attachment to the end portion of the tubular graft conduit. The anchor device defines a constant axial length and a cross-section radially expandable between a first diameter sized for insertion into the aperture in the side wall of the body conduit and a second diameter sized to secure the end portion of the tubular graft conduit coaxially between the anchor device and the lumen of the tubular body conduit. The anchor device defines a longitudinal axis that may change between a substantially straight configuration and a curvilinear configuration such that the cross-section remains substantially unchanged.
