Abstract
Abstract The subject invention relates to a valve replacement system together with methods of preparation and use, are provided for endovascular replacement of a heart valve in a host. The valve replacement system includes up to five components: (a) a prosthetic valve device, (b) a valve introducer device, (c) an intraluminal procedure device, (d) a procedure device capsule (15) and (e) a tissue cutter. The system provides for endovascular removal of a malfunctionning valve and subsequent replacement with a permanent prosthetic heart valve.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
126 words
A device for performing an intraluminal
procedure at a situs in a patient, which has a barrier
(20) to abut the lumen wall when in an expanded
condition; the device including a capsule having a
tubular flexible sleeve (15) with a generally
cylindrical outside surface and a generally cylindrical
inside surface, the capsule being capable of
transporting the barrier (20) endoluminally to said
situs, the barrier (20) being movable relative to the
sleeve (15) to exit from the sleeve, and being
expansible to abut the lumen wall when so exited to
encircle the situs, characterized in that the barrier (20) has a
circumferentially differentially expansible bracer (25)
to allow changes in the angle of a working channel (5)
of the barrier, in relation to the situs.
Claim 2
Dependent Claim
14 words
The device of claim 1, wherein the barrier (20)
is of selectively permeable material.
Claim 3
Dependent Claim
55 words
The device of claim 1, further comprising: a tissue cutter for removal of undesired
tissue, the tissue cutter having at least one blade
(45) and a cable (35), said at least one blade (45)
being movable to an unextended condition and being
capable of endovascular passage to the encircled situs
while in the unextended condition.
Claim 4
Dependent Claim
30 words
The device of claim 4, wherein: said at least one blade (45) has a hinge (30)
for allowing movement of the blade (45) to and from
unextended and extended conditions.
Claim 5
Independent Claim
108 words
A device for performing an intraluminal
procedure at a situs in a patient, which has a valve
introducer for delivering a replacement valve (80), the
valve introducer having an introducer capsule, an
introducer channel (50) and a pusher (60), the
introducer capsule being configured to retain the replacement
valve (80) and endovascularly deliver the replacement
valve to said situs, the introducer channel (50) having
an end attached to the introducer capsule, the
replacement valve being delivered by being forced from
the introducer capsule, characterized by a bracer (70) attached to the
introducer capsule and expansible to hold the
introducer capsule in position during delivery of the
replacement valve.
Claim 6
Dependent Claim
35 words
The device of claim 5, wherein said bracer (70)
is circumferentially differentially expansible so as to
have the capability of holding said introducer capsule
accurately in position during delivery of the
replacement valve device (80).
Claim 7
Dependent Claim
12 words
The device of claim 5, wherein said pusher (60)
is a disc.
