Abstract
Exemplary embodiments comprise AV fistulas and other anastomotic devices for creating new or reinforcing existing side-branch vessels, and/or bridging neighboring vessels together. An exemplary embodiment may comprise a sidewall port, such as a flanged sidewall port, and/or flow frame design, such as a partially bare, flexible stent or a whisk, for purposes of creating a transmural flow. Another exemplary embodiment may comprise a compliant vessel support to aid in the transition from device to vessel and/or vessel to device, and to promote vessel dilation.
Claims20
A stent graft comprising:
- a sidewall port device configured for coupling a conduit through an aperture in a vessel wall, the side wall port device comprising a lattice inverted onto itself to form an inner tube disposed coaxially within an outer tube.
A medical device comprising:
- a first conduit portion configured to transport a fluid within a vessel;
- a second conduit portion in fluid communication with the first conduit portion and configured to transport fluid through an aperture in the vessel;
- and
- a sidewall port device coupled to the second conduit portion, the sidewall port device comprising a lattice inverted onto itself to form an inner tube disposed coaxially within an outer tube.
A medical device comprising:
- a conduit portion configured to transport a fluid from a first vessel into a second vessel;
- and
- a sidewall port device coupled to the conduit portion and to the first vessel, the sidewall port device comprising a lattice inverted onto itself to form an inner tube disposed coaxially within an outer tube.
