Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
131 words
A method of closing a puncture in a blood vessel wall, the method comprising: positioning a suture placement device in a tissue tract and into a puncture in the blood vessel wall; advancing a length of suture in a distal direction from the device through a first penetration in the blood vessel wall adjacent to the puncture; guiding the suture length from the first penetration across a proximal side of the puncture to a second penetration adjacent to the puncture opposite the first penetration; advancing the suture length in a proximal direction through the second penetration and the device so that the two ends of the suture length are accessible external to the tissue tract; and securing the suture length across an anterior side of the puncture to close the puncture.
Claim 2
Independent Claim
131 words
A method of closing a puncture in a blood vessel wall, the method comprising: positioning a suture placement device in a tissue tract and into a puncture in the blood vessel wall; advancing a length of suture in a distal direction from the device through a first penetration in the blood vessel wall adjacent to the puncture; guiding the suture length from the first penetration across a proximal side of the puncture to a second penetration adjacent to the puncture opposite the first penetration; advancing the suture length in a proximal direction through the second penetration and the device so that the two ends of the suture length are accessible external to the tissue tract; and securing the suture length across an anterior side of the puncture to close the puncture.
Claim 3
Dependent Claim
28 words
The method of claim 1 , wherein advancing a length of suture in a distal direction comprises pushing a needle which carries the suture through the first penetration.
Claim 4
Dependent Claim
27 words
The method of claim 2 , wherein guiding the suture length comprises elastically bending the needle as it tracks within the blood vessel to the second penetration.
Claim 5
Dependent Claim
30 words
The method of claim 3 , wherein advancing the suture in a proximal direction comprises pushing the needle so that a needle tip passes proximally out through the tissue tract.
Claim 6
Independent Claim
93 words
A method for suturing a puncture site in a wall of a blood vessel, said method comprising: providing a suturing device having a pair of axially advanceable penetrating elements; advancing the penetrating elements to form two penetrations in the blood vessel wall on opposite sides of the puncture site; advancing suture distally through the suture device distally through one of the two penetrations into a lumen of the blood vessel, proximally through the other of the two penetrations, and proximally through the suturing device; and securing the suture to close the puncture site.
Claim 7
Independent Claim
93 words
A method for suturing a puncture site in a wall of a blood vessel, said method comprising: providing a suturing device having a pair of axially advanceable penetrating elements; advancing the penetrating elements to form two penetrations in the blood vessel wall on opposite sides of the puncture site; advancing suture distally through the suture device distally through one of the two penetrations into a lumen of the blood vessel, proximally through the other of the two penetrations, and proximally through the suturing device; and securing the suture to close the puncture site.
Claim 8
Dependent Claim
13 words
The method of claim 5 , wherein the penetrating elements are needle guides.
Claim 9
Dependent Claim
35 words
The method of claim 6 , wherein advancing the suture comprises pushing the suture distally through a lumen of a first needle guide tube and pulling the suture proximally through a second needle guide tube.
Claim 10
Dependent Claim
44 words
The method of claim 7 , wherein advancing the suture comprises providing a needle having the suture attached thereto and pushing the needle distally through the lumen of the first needle guide tube and pulling the needle proximally through the second needle guide tube.
Claim 11
Independent Claim
81 words
A method of suturing a puncture site in a wall of a blood vessel, said method comprising: providing a length of suture; pushing the suture distally through a tissue tract over the puncture site through a penetration on one side of the puncture site into a lumen of the blood vessel; pulling the suture proximally through a second penetration on another side of the puncture site and proximally through the tissue tract; and securing the suture to close the puncture site.
Claim 12
Independent Claim
81 words
A method of suturing a puncture site in a wall of a blood vessel, said method comprising: providing a length of suture; pushing the suture distally through a tissue tract over the puncture site through a penetration on one side of the puncture site into a lumen of the blood vessel; pulling the suture proximally through a second penetration on another side of the puncture site and proximally through the tissue tract; and securing the suture to close the puncture site.
Claim 13
Independent Claim
117 words
A device for suturing a puncture in a blood vessel wall, said device comprising: a body arranged to be positioned through a tissue tract over the blood vessel puncture, said body having a path for, (a) advancing a suture length in a distal direction past a first gap in the body, (b) advancing the suture laterally on a distal side of the gap, and (c) proximally through a second gap in the body, wherein the gaps are arranged to capture the edges of the blood vessel wall adjacent to the puncture so that the suture advances distally through one edge, laterally across a distal side of the puncture, and proximally through the other edge of the puncture.
Claim 14
Independent Claim
117 words
A device for suturing a puncture in a blood vessel wall, said device comprising: a body arranged to be positioned through a tissue tract over the blood vessel puncture, said body having a path for, (a) advancing a suture length in a distal direction past a first gap in the body, (b) advancing the suture laterally on a distal side of the gap, and (c) proximally through a second gap in the body, wherein the gaps are arranged to capture the edges of the blood vessel wall adjacent to the puncture so that the suture advances distally through one edge, laterally across a distal side of the puncture, and proximally through the other edge of the puncture.
Claim 15
Dependent Claim
37 words
The device according to claim 10 , wherein the body comprises a shaft having a nose piece, wherein the gaps are positioned between a distal end of the shaft and a proximal surface of the nose piece.
Claim 16
Dependent Claim
26 words
The device according to claim 10 , wherein the device further includes a needle, the needle being configured to carry the suture through the suture path.
Claim 17
Dependent Claim
46 words
The device according to claim 12 , wherein the device further comprises a pair of needle guide tubes, said guide tubes arranged to be advanced across the gaps to penetrate the edges of the blood vessel wall to form penetrations prior to advancement of the needle.
