Abstract
Abstract A prosthetic valve assembly for use in replacing a deficient native valve comprises a replacement valve supported on an expandable valve support. If desired, one or more anchor may be used. The valve support, which entirely supports the valve annulus, valve leaflets, and valve commissure points, is configured to be collapsible for transluminal delivery and expandable to contact the anatomical annulus of the native valve when the assembly is properly positioned. The anchor engages the lumen wall when expanded and prevents substantial migration of the valve assembly when positioned in place. The prosthetic valve assembly is compressible about a catheter, and restrained from expanding by an outer sheath. The catheter may be inserted inside a lumen within the body, such as the femoral artery, and delivered to a desired location, such as the heart. When the outer sheath is retracted, the prosthetic valve assembly expands to an expanded position such that the valve and valve support expand within the deficient native valve, and the anchor engages the lumen wall.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
88 words
1 . A prosthetic valve assembly for use in replacing a deficient native valve, the valve assembly comprising: a valve having a plurality of resilient leaflets; a valve support configured to be collapsible for transluminal delivery and expandable to contact the anatomical annulus of the native valve when the assembly is properly positioned, said valve support supporting the base and the commissure points of the valve; and an anchor for engaging the lumen wall when expanded in place for preventing substantial migration of the valve assembly after deployment.
Claim 2
Dependent Claim
88 words
1 . A prosthetic valve assembly for use in replacing a deficient native valve, the valve assembly comprising: a valve having a plurality of resilient leaflets; a valve support configured to be collapsible for transluminal delivery and expandable to contact the anatomical annulus of the native valve when the assembly is properly positioned, said valve support supporting the base and the commissure points of the valve; and an anchor for engaging the lumen wall when expanded in place for preventing substantial migration of the valve assembly after deployment.
Claim 3
Dependent Claim
17 words
2 . The valve assembly of claim 1 , wherein the leaflets are made of natural tissue.
Claim 4
Dependent Claim
17 words
3 . The valve assembly of claim 1 , wherein the leaflets are made of synthetic material.
Claim 5
Dependent Claim
17 words
4 . The valve assembly of claim 1 , wherein the valve support and anchor are self-expanding.
Claim 6
Dependent Claim
36 words
5 . The valve assembly of claim 4 , wherein the configuration and radial force of the valve support substantially preclude any portion of the native valve that remains from obstructing effective placement of said assembly.
Claim 7
Dependent Claim
19 words
6 . The valve assembly of claim 1 , wherein the valve support comprises a single length of wire.
Claim 8
Dependent Claim
27 words
7 . The valve assembly of claim 1 , wherein the anchor is configured to exert sufficient radial forces against the lumen wall to prevent substantial migration.
Claim 9
Dependent Claim
13 words
8 . The valve assembly of claim 1 further comprising a second anchor.
Claim 10
Dependent Claim
19 words
9 . The valve assembly of claim 1 wherein the anchor is flared to conform to the local anatomy.
Claim 11
Dependent Claim
38 words
10 . The valve assembly of claim 1 further comprising a delivery catheter having a distally positioned sheath to house the valve assembly in a collapsed position for transluminal delivery and deployment of the valve assembly where desired.
Claim 12
Dependent Claim
29 words
11 . The valve assembly of claim 10 , further comprises at least one hook for engaging a portion of the valve support for controlled release of said support.
Claim 13
Dependent Claim
17 words
12 . The valve assembly of claim 1 wherein the anchor is spaced from the valve support.
Claim 14
Dependent Claim
106 words
13 . A method of replacing a deficient native valve comprising the steps of: providing a prosthetic valve assembly, the assembly comprising a valve, a valve support permitting attachment thereto of the base and the commissures of the valve, and an anchor for engaging the lumen wall when expanded for preventing substantial migration of the valve assembly when positioned in place; collapsing the valve support and anchor to fit within a distally positioned sheath on a catheter; advancing the catheter to the deficient native valve; deploying the valve assembly; and withdrawing the catheter, leaving the valve assembly to function in place of the deficient native valve.
Claim 15
Dependent Claim
106 words
13 . A method of replacing a deficient native valve comprising the steps of: providing a prosthetic valve assembly, the assembly comprising a valve, a valve support permitting attachment thereto of the base and the commissures of the valve, and an anchor for engaging the lumen wall when expanded for preventing substantial migration of the valve assembly when positioned in place; collapsing the valve support and anchor to fit within a distally positioned sheath on a catheter; advancing the catheter to the deficient native valve; deploying the valve assembly; and withdrawing the catheter, leaving the valve assembly to function in place of the deficient native valve.
