Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
101 words
A method of securing tissue, comprising: delivering an introducer transluminally through a blood vessel to a location adjacent a first tissue portion; advancing said introducer through said first tissue portion and a second tissue portion, the introducer having a sharpened tip to penetrate the tissue portions, the introducer removably carrying an anchor at least partially through the tissue portions; and retracting the introducer from the tissue portions, leaving the anchor in position in the tissue portions; whereby the anchor secures the first and second tissue portions together by resisting proximal and distal migration of the anchor relative to the tissue portions.
Claim 2
Independent Claim
101 words
A method of securing tissue, comprising: delivering an introducer transluminally through a blood vessel to a location adjacent a first tissue portion; advancing said introducer through said first tissue portion and a second tissue portion, the introducer having a sharpened tip to penetrate the tissue portions, the introducer removably carrying an anchor at least partially through the tissue portions; and retracting the introducer from the tissue portions, leaving the anchor in position in the tissue portions; whereby the anchor secures the first and second tissue portions together by resisting proximal and distal migration of the anchor relative to the tissue portions.
Claim 3
Dependent Claim
24 words
The method of claim 1 , wherein the anchor is provided with one or more distal barbs for resisting proximal migration of the anchor.
Claim 4
Dependent Claim
24 words
The method of claim 1 , wherein the anchor is provided with one or more proximal barbs for resisting distal migration of the anchor.
Claim 5
Dependent Claim
26 words
The method of claim 1 , wherein the anchor is provided with proximal and distal barbs for resisting distal and proximal migration, respectively, of the anchor.
Claim 6
Dependent Claim
14 words
The method of claim 1 , wherein the anchor is carried on the introducer.
Claim 7
Dependent Claim
14 words
The method of claim 1 , wherein the introducer is delivered through a tube.
Claim 8
Dependent Claim
14 words
The method of claim 1 , wherein the anchor is connected to a suture.
Claim 9
Dependent Claim
14 words
The method of claim 1 , wherein the anchor is made from a wire.
Claim 10
Dependent Claim
11 words
The method of claim 1 , wherein the anchor is superelastic.
Claim 11
Dependent Claim
39 words
The method of claim 1 , wherein the anchor is delivered at least partially through the tissue portions in a collapsed configuration, and expands to an expanded configuration after retraction of the introducer to secure the tissue portions together.
Claim 12
Dependent Claim
37 words
The method of claim 1 , wherein the anchor has a proximal portion adapted to engage a surface of the first tissue portion, and a distal portion adapted to engage a surface of the second tissue portion.
Claim 13
Dependent Claim
21 words
The method of claim 11 , further comprising radially enlarging the proximal and distal portions to secure the tissue portions together.
Claim 14
Dependent Claim
18 words
The method of claim 1 , further comprising axially shortening the anchor to secure the tissue portions together.
Claim 15
Dependent Claim
22 words
The method of claim 1 , further comprising delivering the introducer to the location adjacent the first tissue portion through a catheter.
Claim 16
Independent Claim
95 words
A method of securing a first tissue portion to a second tissue portion comprising: providing a catheter having at least one anchor support moveable between an axial orientation and an inclined orientation, and an anchor carried by the at least one anchor support; advancing the catheter to a target site near the first tissue portion while the anchor supports are in the axial orientation; moving the anchor support from the axial orientation to the inclined orientation; and deploying at least one anchor from the anchor support into the first tissue portion and second tissue portion.
Claim 17
Independent Claim

Claim 23
Independent Claim
176 words
A method of securing a first tissue portion to a second tissue portion comprising: advancing a catheter to a position adjacent at least the first tissue portion; and deploying at least one tissue anchor from the catheter and into the first tissue portion and second tissue portion, wherein the at least one tissue anchor comprises a body having at least one proximal arm integrally formed with the body being moveable from a collapsed configuration in which the proximal arm is generally axially aligned with the body to an outwardly extending configuration in which the proximal arm is biased in a generally distal direction, the proximal arm engaging the first tissue portion; and wherein the body of the at least one tissue anchor has at least one distal arm integrally formed with the body being moveable from a collapsed configuration in which the distal arm is generally axially aligned with the body to an outwardly extending configuration in which the distal arm is biased in a generally proximal direction, the distal arm engaging the second tissue portion.
