Abstract
A modular prosthetic conduit system such as a stent or stent graft system tailored for the repair of aneurysms or other compromised vessel walls. The stent or stent graft system incorporates various means to interlock the multiple modular components used in the repair procedure. The present invention further provides a modular stent graft system tailored for the repair of aneurysms or other compromised vessel walls that cross or are adjacent to a branch or bifurcation in a vessel.
Claims25
A prosthetic conduit system comprising:
- an expandable main conduit having a first open end, a second open end, a main conduit wall extending between the first open end and the second open end, an outer conduit surface, and an inner conduit surface having at least one protuberance extending therefrom;
- and
- an expandable secondary conduit having at least a portion thereof disposed inside the main conduit, the secondary conduit extending along an axis between a first open end and an opposite second open end, a secondary conduit wall extending between the first open end and second open end of the secondary conduit and having an outer conduit surface, and an attachment portion extending generally outwardly from the secondary conduit wall at an angle of less than 90 degrees relative to the outer conduit surface of the secondary conduit wall when in a deployed state and engaging the at least one protuberance of the main conduit to constrain axial displacement of the secondary conduit relative to the main conduit.
