Device and method for suturing of internal puncture sites
First Claim
1. A method of closing a puncture in a blood vessel wall, the method comprising:
- positioning a suture placement device through the puncture in the blood vessel wall, the placement device having a length of suture with a first end, a second end and a bight between the first and second ends with the bight being prearranged on the device to define a pre-tied knot when the first end of the suture passes through the bight;
advancing the first end of the 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; and
advancing the suture length in a proximal direction through the second penetration, through the device, and through the bight so that the two ends of the suture length are accessible for securing the suture across the puncture to close the puncture.

Abstract
A method of closing a puncture in a blood vessel wall, including: positioning a suture placement device in a tissue tract and into a puncture in the blood vessel wall, the placement device having a length of suture with a first end, a second end and a bight between the first and second ends with the bight being prearranged on the device to define a pre-tied knot when the first end of the suture passes through the bight; advancing the first end of the 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; and advancing the suture length in a proximal direction through the second penetration, through the device, and through the bight so that the two ends of the suture length are accessible external to the tissue tract for securing the suture across the puncture to close the puncture.

5. 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 and a length of suture having a first end, a second end and a bight between the first and second ends, the bight being prearranged on the suturing device to define a pre-tied knot when the first end of the suture passes through the bight;
advancing the penetrating elements to form two penetrations in the blood vessel wall on opposite sides of the puncture site;
advancing the first end of the 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, proximally through the suturing device, and through the bight; and
securing the pre-tied knot to close the puncture site. - View Dependent Claims (6, 7, 8)

9. A method of suturing a puncture site in a wall of a blood vessel, said method comprising:
-
providing a length of suture having a first end, a second end and a bight between the first and second ends, the bight being prearranged and adapted to receive the first end therethrough to define a pre-tied knot when the first end of the suture passes through the bight;
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;
passing the suture through the bight; and
securing the pre-tied knot to close the puncture site. - View Dependent Claims (10, 11, 12)

13. 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; and
a length of suture having a first end, a second end and a bight between the first and second ends, the bight being prearranged on the body to define a pre-tied knot when the first end of the suture passes through the bight;
said body having a suture path for (a) advancing the first end of the 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 past a second gap in the body, wherein the gaps are arranged to engage 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 blood vessel wall, proximally through the other edge of the blood vessel wall, and through the bight. - View Dependent Claims (14, 15, 16, 17)

18. A suturing device comprising:
-
a shaft having a proximal end, a distal end, an entry lumen, and an exit lumen;
a length of suture having a first end, a second end and a bight between the first and second ends, the bight being prearranged on the shaft to define a pre-tied knot when the first end of the suture passes through the bight;
a nose piece attached to the distal end of the shaft and having a return lumen disposed to receive a flexible needle from the entry lumen and to turn the needle to enter the exit lumen, wherein the nose piece is axially spaced-apart from the distal end of the shaft to form an annular gap between the shaft and a proximal end of the nose piece which receives tissue to be sutured. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)

26. A suturing kit comprising:
-
a suturing needle including an elongate needle shank having a distal tip, said shank being composed of a flexible metal alloy;
a length of suture having a first end connected to the needle, a second end and a bight between the first and second ends, the bight being prearranged on the body to define a pre-tied knot when the first end of the suture passes through the bight; and
a suturing device comprising a shaft having a proximal end, a distal end, an entry lumen, and an exit lumen;
a nose piece attached to the distal end of the shaft and having a return lumen disposed to receive the flexible needle from the entry lumen and to turn the needle to enter the exit lumen, wherein the nose piece is axially spaced-apart from the distal end of the shaft to form an annular gap between the shaft and a proximal end of the nose piece which receives tissue to be sutured.
