Abstract
Abstract A system for minimally invasive insertion of a bioprosthetic heart valve. The system includes a collapsible tissue-based valve system, a catheter-based valve delivery system, a surgical platform and a device tracking and visualization system. The collapsible valve system includes: (i) a permanent outer frame ( 10 ) that is affixed to the patient using conventional sutures or staples, and (ii) a collapsible valve ( 20 ) having a collapsible inner frame ( 21 ) that mates with the outer frame ( 10 ), and supports valve leaflets ( 13 ). The inner frame ( 21 ) is moved to a collapsed position and located at the previously installed outer frame ( 10 ). The inner frame ( 21 ) is then expanded to lock the inner frame ( 21 ) to the outer frame ( 10 ). The inner frame ( 21 ) may be re-collapsed and disengaged from the outer frame ( 10 ). A new collapsible valve ( 20 ) is then installed, to resume the function of the prosthesis.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
61 words
A heart valve system comprising: first frame means attachable to tissue; and second frame means engageable and disengageable with said first frame means, wherein said second frame means includes a plurality of articulated segments, said second frame means movable between an expanded position to engage with the first frame means and a collapsed position to disengage from the first frame means.
Claim 2
Dependent Claim
61 words
A heart valve system comprising: first frame means attachable to tissue; and second frame means engageable and disengageable with said first frame means, wherein said second frame means includes a plurality of articulated segments, said second frame means movable between an expanded position to engage with the first frame means and a collapsed position to disengage from the first frame means.
Claim 3
Dependent Claim
26 words
A heart valve system according to claim 1 , wherein said second frame means supports occluding means movable between an occluded position and an open position.
Claim 4
Dependent Claim
19 words
A heart valve system according to claim 2 , wherein said occluding means includes at least one leaflet occluder.
Claim 5
Dependent Claim
16 words
A heart valve system according to claim 3 , wherein said leaflet occluder includes biological tissue.
Claim 6
Dependent Claim
16 words
A heart valve system according to claim 3 , wherein said leaflet occluder includes bovine pericardium.
Claim 7
Dependent Claim
15 words
A heart valve system according to claim 1 , wherein said articulated segments are rigid.
Claim 8
Dependent Claim
40 words
A heart valve system according to claim 1 , wherein at least one of said plurality of articulated segments includes a projection member for facilitating the movement of said second frame means between said expanded position and said collapsed position.
Claim 9
Dependent Claim
59 words
A heart valve system according to claim 1 , wherein said plurality of articulated segments define a first outer diameter when said second frame means is moved to said collapsed position, and define a second outer diameter when said second frame means is moved to said expanded position, said first outer diameter being less than said second outer diameter.
Claim 10
Dependent Claim
19 words
A heart valve system according to claim 1 , wherein said plurality of articulated segments articulate by pin joints.

Claim 12
Dependent Claim
19 words
A heart valve system according to claim 1 , wherein said articulated segments articulate by ball and socket joints.
Claim 13
Dependent Claim
29 words
A heart valve system according to claim 1 , wherein said first frame means includes a rigid member having interface means for reversibly engaging said second frame means therewith.
Claim 14
Dependent Claim
38 words
A heart valve system according to claim 12 , wherein said interface means includes a groove member for receiving at least a portion of said second frame means when said second frame means is in the expanded position.
Claim 15
Dependent Claim
26 words
A heart valve system according to claim 1 , wherein said first frame means includes attachment means for attaching said first frame means to said tissue.
Claim 16
Dependent Claim
17 words

Claim 17
Dependent Claim
60 words
A valve system comprising: first frame means attachable to bodily tissue; second frame means engageable and disengageable with said first frame means, wherein said second frame means is movable between an expanded position to engage with the first frame means, said a collapsed position to disengage from the first frame means; and valve means supported by said second frame means.
Claim 18
Dependent Claim
60 words
A valve system comprising: first frame means attachable to bodily tissue; second frame means engageable and disengageable with said first frame means, wherein said second frame means is movable between an expanded position to engage with the first frame means, said a collapsed position to disengage from the first frame means; and valve means supported by said second frame means.
Claim 19
Dependent Claim
15 words
