Abstract

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a valved conduit. The valved conduit may include at least one leaflet and an interior surface that mitigates against thrombus formation within the conduit.

First claim

What is claimed is:

1. A valved conduit comprising:
a conduit having an interior surface and an exterior surface; and
at least one leaflet having an external portion non-mechanically and suturelessly attached to the exterior surface of the conduit and an internal portion arranged within the interior surface of the conduit to mitigate against thrombus formation within the conduit the an external portion of the at least one leaflet is adhered to the exterior surface of the conduit by a layer of adhesive film; and
a flexible film arranged about a circumference of the conduit and the adhesive film.

2. The valved conduit of claim 1 , wherein the conduit is free of sinuses.

3. The valved conduit of claim 1 , wherein the conduit is free of mechanical coupling.

4. The valved conduit of claim 1 , wherein the adhesive film is arranged about a circumference of the conduit.

5. The valved conduit of claim 1 , wherein the flexible film includes expanded Polytetrafluoroethylene (ePTFE) and the adhesive film comprises fluorinated ethylene propylene (FEP).

6. The valved conduit of claim 1 , further comprising a support frame coupled to the conduit by the flexible film.

7. The valved conduit of claim 6 , wherein the support frame is formed of polyether ether ketone (PEEK).

8. The valved conduit of claim 1 , further comprising at least one radiopaque markers arranged adjacent to the at least one leaflet on the exterior surface of the conduit.

9. The valved conduit of claim 1 , wherein the interior surface of the conduit is diametrically constant and free of any macroscopic interruptions.

10. The valved conduit of claim 1 , wherein the at least one leaflet is positioned within the conduit at a longitudinal location along a length of the conduit, and the conduit is diametrically constant at the longitudinal location where the at least one leaflet is positioned and through adjacent proximal and distal portions of the conduit.

11. A valved conduit comprising:
a conduit having an interior surface, an exterior surface, a proximal portion, and a distal portion;
a leaflet attachment portion having an opening between the interior surface and the exterior surface of the conduit; and
a plurality of leaflets separated from one another within the interior of the conduit by commissure gaps, each of the plurality of leaflets having an attachment section attached to the exterior surface of the conduit without mechanical alteration of the interior surface or the exterior surface of the conduit to mitigate against throm bus formation within the conduit.

12. The valved conduit of claim 11 , wherein the plurality of leaflets includes three leaflets.

13. The valved conduit of claim 12 , wherein the commissure gaps separating the leaflets at the attachment section of each of the three leaflets to form the gaps between the three leaflets within the interior surface of the conduit.

14. The valved conduit of claim 11 , wherein the attachment section is attached to the exterior surface of the conduit by an adhesive, thermal bonding, or chemical bonding.

15. The valved conduit of claim 11 , wherein the attachment section includes a first portion and a second portion, and the first portion is attached to the proximal portion of the exterior surface of the conduit, and the second portion is attached to the distal portion of the exterior surface of the conduit.

16. The valved conduit of claim 11 , wherein the leaflet attachment portion is a portion of the conduit, and the leaflet attachment portion is denser than remaining portions of the conduit.

17. The valved conduit of any one of claims 11 - 16 , further comprising a directional indicator on the exterior surface of the conduit to indicate the direction of blood flow within the conduit.
