BIFURCATED TUBULAR GRAFT FOR TREATING TRICUSPID REGURGITATION
First Claim
Patent Images
1. A medical device for treating tricuspid valve regurgitation, comprising:
- a bifurcated endograft having a Y-shaped configuration including a first leg, a second leg and a third leg all in fluid communication;
the first leg having a first length and being configured for extending into the superior vena cava (SVC) and a first stent adjacent a distal end of the first leg for attaching the first leg to the SVC;
the second leg having a second length and being configured for extending into the inferior vena cava (IVC) and a second stent adjacent a distal end of the second leg for attaching the second leg to the IVC;
the third leg having a third length and being configured for extending into the right atrium and through the tricuspid valve;
the third leg having a third stent adjacent a distal end of the third leg to hold open the tricuspid valve; and
a bioprosthetic valve positioned in the third leg and spaced proximal to the third stent a distance in the range from 0.0394 in. to 1.1811 in. (1.0 mm to 30.0 mm).

Abstract
A lubricated tubular graft is implanted in the inferior vena cava and the superior vena cava in order to control the inflow of blood to the right atrium. A bifurcated leg with a non-collapsing stent extends across the tricuspid valve. A bioprosthetic valve is positioned proximal of the stent in the bifurcated leg in order to regulate flow through the tricuspid valve and to eliminate tricuspid regurgitation.

7. A medical device for treating tricuspid valve regurgitation, comprising:
-
a tubular graft having a Y-shaped configuration including a tubular main body and a tubular leg portion extending from the tubular main body and being in fluid communication; the tubular main body having first end extending into the superior vena cava (SVC) and a first stent adjacent a first end for attaching the tubular main body to the SVC; the tubular main body having a second end extending into the inferior vena cava (IVC) and a second stent adjacent a second end for attaching the tubular main body to the IVC; the tubular leg portion being configured for extending into the right atrium and through the tricuspid valve; the tubular leg portion having a third stent adjacent a distal end of the tubular leg portion to hold open the tricuspid valve; and a bioprosthetic valve positioned in the tubular leg portion and spaced proximal to the third stent a distance in the range from 0.0394 in. to 1.1811 in. (1.0 mm to 30.0 mm). - View Dependent Claims (8, 9, 10, 11, 12)
