Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 91 words
A prosthetic valve replacement system for implantation at a target site within a subject, said system comprising: a valve mechanism; a fixation mechanism for retaining said valve mechanism in a fixed position at said target site; and magnetic means comprising magnetic material for magnetically coupling said valve mechanism with said fixation mechanism, wherein said fixation mechanism is changeable from a collapsed condition with magnetic material folded radially inward from a coupling position to an expanded condition with the magnetic material positioned at the coupling position for coupling with the valve mechanism.
Claim 2
Dependent Claim 91 words
A prosthetic valve replacement system for implantation at a target site within a subject, said system comprising: a valve mechanism; a fixation mechanism for retaining said valve mechanism in a fixed position at said target site; and magnetic means comprising magnetic material for magnetically coupling said valve mechanism with said fixation mechanism, wherein said fixation mechanism is changeable from a collapsed condition with magnetic material folded radially inward from a coupling position to an expanded condition with the magnetic material positioned at the coupling position for coupling with the valve mechanism.
Claim 3
Dependent Claim 31 words
The system of claim 1 , wherein magnetic material is provided as magnetic elements provided at spaced locations along the fixation mechanism that in its expanded condition comprises an annular element.
Claim 4
Dependent Claim 38 words
The system of claim 2 , wherein a plurality of pairs of magnetic elements are provided with hinge lines between at least one pair of magnetic elements to permit folding of the fixation mechanism to the collapsed condition.
Claim 5
Dependent Claim 25 words
The system of claim 1 , further comprising a stent operatively connected with the fixation mechanism that expands radially as the stent is axially shortened.
Claim 6
Dependent Claim 37 words
The system of claim 4 , wherein the stent is self-expanding so that by releasing a constriction provided to the stent, the stent expands to change the fixation mechanism from the collapsed condition to the expanded condition.
Claim 7
Dependent Claim 33 words
The system of claim 4 , wherein the stent is deformable so that by expanding the fixation mechanism, the stent is also expanded to maintain the fixation mechanism in the expanded condition thereof.
Claim 8
Dependent Claim 95 words
A prosthetic valve replacement system for implantation at a target site within a subject, said system comprising: a valve mechanism; a fixation mechanism for retaining said valve mechanism in a fixed position at said target site; and magnetic means comprising magnetic material for magnetically coupling said valve mechanism with said fixation mechanism, wherein said fixation mechanism comprises an annular ring including magnetic material arranged as a substantially annular surface for coupling to a substantially similarly arranged annular surface of magnetic material provided to the valve mechanism for coupling the fixation mechanism with the valve mechanism.
Claim 9
Dependent Claim 95 words
A prosthetic valve replacement system for implantation at a target site within a subject, said system comprising: a valve mechanism; a fixation mechanism for retaining said valve mechanism in a fixed position at said target site; and magnetic means comprising magnetic material for magnetically coupling said valve mechanism with said fixation mechanism, wherein said fixation mechanism comprises an annular ring including magnetic material arranged as a substantially annular surface for coupling to a substantially similarly arranged annular surface of magnetic material provided to the valve mechanism for coupling the fixation mechanism with the valve mechanism.
Claim 10
Dependent Claim 24 words
The system of claim 7 , wherein the magnetic material is provided as a plurality of discontinuous spaced segments arranged as the annular ring.
Claim 11
Dependent Claim 20 words
The system of claim 7 , wherein the magnetic material is provided as a continuous annular ring of magnetic material.
