Abstract
A right ventricle-pulmonary artery conduit provides a first end having a first disc extending radially therefrom and a second disc, proximate to the first disc. The second disc extends radially from the first end. An expandable lumen section extends between the first disc and the second disc. The conduit also has a second end, distal from the first end.
Claims8
A right ventricle-pulmonary artery conduit comprising:
- a distal end having:
- a first disc extending radially therefrom;
- a second disc, proximate to the first disc, wherein the second disc extends radially from the first end;
- and
- an expandable lumen section extending between the first disc and the second disc;
- a stent structure connecting the first disc and the second disc with each other, the stent structure comprising a plurality of linear struts;
- and
- a proximal end, distal from the distal end;
- a longitudinal axis extending between the distal end and the proximal end such that the struts extend obliquely relative to the longitudinal axis to support the first disc and the second disc;
- and
- a conduit attached to the second disc and extending to the proximal end, the conduit having a plurality of reinforcing rings extending radially along a length thereof.

A right ventricle-pulmonary artery conduit assembly comprising:
- a delivery catheter having a proximal end and a distal end;
- and
- a right ventricle-pulmonary artery conduit removably mounted on the distal end of the catheter, the conduit comprising:
- a first end having:
- a distal disc extending radially therefrom, the distal disc being constructed from a first pliable material;
- a proximal disc, proximate to the distal disc, wherein the proximal disc extends radially from the first end, the proximal disc being constructed from a second pliable material;
- a plurality of linear struts connecting the distal disc to the proximal disc;
- and
- an expandable lumen section extending between the distal disc and the proximal disc inside a volume defined by the struts;
- and
- a second end, distal from the first end the second end having a conduit extending away from the second disc, the conduit comprising a plurality of reinforcing rings around n external perimeter thereof.

A right ventricle-pulmonary artery conduit comprising:
- a distal end having an expandable portion, the expandable portion comprising:
- a first disc constructed from a first pliable material;
- a second disc, proximal of the first disc, the second disc constructed from a second pliable material;
- a plurality of straight, linear struts connecting and supporting the first disc and the second disc to each other;
- and
- a lumen section providing fluid communication between the first disc and the second disc;
- and
- a proximal end comprising a conduit body connected to and extending proximally from the second disc,
- wherein the expandable portion is in a collapsed condition in a pre-deployment condition and is in an expanded position in a post deployment condition, such that the first disc is configured for deployment inside a wall, the second disc is configured for deployment outside the wall.
