Abstract

A cardiovascular valve assembly comprised of a base member and an exchangeable valve member detachably mountable thereto. The base member includes a tubular body. The valve member includes a valve frame that supports a plurality of valve leaflets. The diameter of the tubular body can be increased to receive an exchangeable valve member having larger dimensions.

Claims (14)

13. A valve assembly according to claim 12, wherein said tubular body is a mesh comprised of a plurality of intersecting elongate members, said elongate members intersecting at intersection points.

15. A valve assembly according to claim 12, wherein said adjustable diameter of said tubular body can be sequentially increased to receive a series of valve members having valve frames of incrementally larger diameter.

16. A valve assembly according to claim 12, each said securing element is moveable relative to the tubular body to maintain an aspect ratio after enlargement of the diameter of the tubular body.

17. A valve assembly according to claim 12, wherein each said securing element includes:
a pair of arms pivotally connected to said tubular body, said arms moveable relative to each other when the diameter of said tubular body is adjusted; and a strap extending between said pair of arms to define an opening dimensioned to receive said finger.

18. A valve assembly according to claim 12, wherein each said securing element includes:
