Abstract

A cardiovascular valve assembly is disclosed including a housing assembly comprising a first portion and a second portion removably attached to the first portion. A valve may be positioned within the housing assembly. The valve, which may be a mechanical valve, a biological tissue valve, or a polymeric valve, may be structured to allow fluid to flow through the housing assembly in a single direction. In certain embodiments, the valve assembly may further include at least one coupling structure provided on the second portion and at least one aperture defined in the first portion, with the aperture structured to receive the coupling structure to couple the first portion to the second portion. Corresponding systems incorporating cardiovascular valve assemblies are also disclosed.

First claim

What is claimed is:

1. A cardiovascular valve assembly, comprising: a housing assembly, the housing assembly comprising:
a first portion having first and second ends, a first outer surface, an internal cavity, and at least one coupling structure extending from a first undulating surface of the second end of the first portion, the at least one coupling structure and the first undulating surface being positioned inward from the first outer surface at the second end of the first portion;
a second portion removably attached to the first portion and having first and second ends, a second outer surface, an internal cavity, and at least one coupling aperture positioned inward from the second outer surface within a second undulating surface at the second end of the second portion, the at least one coupling aperture being structured to receive the coupling structure to couple the first portion to the second portion, the at least one coupling structure being positioned completely within the first and second outer surfaces when the cardiovascular valve assembly is assembled;
a valve positioned within the housing assembly and having at least one valve aperture defined therein and a cuff, the cuff being positioned between the first and second undulating surfaces when the cardiovascular valve assembly is assembled;
wherein the valve is structured to allow fluid to flow through the housing assembly in a single direction; wherein the at least one coupling structure extends through the at least one valve aperture and through the at least one coupling aperture to couple the first portion and the valve to the second portion.

2. The cardiovascular valve assembly of claim 1 , wherein the valve comprises at least one of:
a mechanical valve;
a biological tissue valve;
a polymeric valve.

3. The cardiovascular valve assembly of claim 1 , wherein:
the first portion comprises a first connector, the first connector structured to removably attach the first portion to a first conduit;
the second portion comprises a second connector, the second connector structured to removably attach the second portion to a second conduit.

4. The cardiovascular valve assembly of claim 1 , wherein the valve is a biological tissue valve.

5. The cardiovascular valve assembly of claim 1 , wherein the at least one valve aperture is defined in the cuff member.

6. The cardiovascular valve assembly of claim 5 , wherein the at least one coupling structure extends axially from the first portion, and the at least one valve aperture and at least one coupling aperture are arranged axially.

7. The cardiovascular valve assembly of claim 1 , further comprising at least one seal member positioned between the first portion and the second portion, the seal member configured to prevent fluid from escaping the housing assembly.

8. The cardiovascular valve assembly of claim 1 , wherein, when the first portion is removably attached to the second portion, the first and second portions form a seal to prevent fluid from escaping the housing assembly.

9. The cardiovascular valve assembly of claim 1 , further comprising at least one identifying indicia configured to identify a desired direction for fluid flow.

10. A cardiovascular valve assembly, comprising: a housing assembly, the housing assembly comprising:
a first portion comprising first and second ends, a first outer surface, an internal cavity, and a plurality of coupling structures extending from a first three-dimensionally undulating surface, the first three-dimensionally undulating surface being contoured along a longitudinal axis extending through the housing assembly;
a second portion comprising first and second ends, a second outer surface, an internal cavity, and a plurality of apertures positioned inward from the second outer surface in a second three-dimensionally undulating surface at the second end of the second portion and structured to receive the plurality of coupling structures to removably attach the first portion to the second portion, the second three-dimensionally undulating surface being contoured along the longitudinal axis extending through the housing assembly, the plurality of coupling structures being positioned completely within the first and second outer surfaces when the cardiovascular valve assembly is assembled;
a valve positioned within the housing assembly;
a cuff member around the valve, the cuff member being positioned between the first and second undulating surfaces when the cardiovascular valve assembly is assembled;
at least one seal member positioned between the first portion and the second portion, the seal member configured to prevent fluid from escaping the housing assembly;
at least one graphical illustration identifying indicia configured to indicate a desired direction for fluid flow;
wherein the valve is structured to allow fluid to flow through the housing assembly in a single direction.

11. The cardiovascular valve assembly of claim 10 , wherein the plurality of coupling structures extend axially from the first portion of the housing assembly.

12. The cardiovascular valve assembly of claim 10 , wherein the plurality of apertures are arranged axially in the second portion of the housing assembly.

13. The cardiovascular valve assembly of claim 10 , wherein the valve includes a valve opening that allows fluid to flow through the housing assembly, and a plurality of perimeter apertures, wherein the plurality of coupling structures extend through the plurality of perimeter apertures.

14. The cardiovascular valve assembly of claim 10 , wherein the first and second three-dimensionally undulating surfaces are configured with a portion of one of the first and second three-dimensionally undulating surfaces positioned between portions of the other of the first and second three-dimensionally undulating surfaces when the valve assembly is assembled.

15. The cardiovascular valve assembly of claim 10 , wherein the first and second three-dimensionally undulating surfaces each comprise a plurality of depths relative to the longitudinal axis of the housing assembly.
