Abstract

A vessel closure device is provided that may include a guide member, one or more needle guides disposed at least partially within the guide member, and an angle adjustment member movably attached to the guide member. The needle guides may be configured to move between a first position wherein the needle guides are substantially straightened at least partially within the guide member and a second position wherein the needle guides at least partially extend radially and distally away from the guide member. The angle adjustment member may be configured to move between a first position and a second position wherein the angle adjustment member can selectively deflect the needle guides radially toward the guide member when the needle guides are in the second position.

Claims

1. A vessel closure device, the device comprising:

a guide member having a proximal end, a distal end, and one or more lumens extending from the proximal end to one or more openings adjacent the distal end, a distalmost end of the device being formed with a tapered portion disposed distal the one or more openings, a distal end of the tapered portion being the distalmost end of the device, the proximal end of the guide member being mounted to a proximal handle;

a pair of needle guides disposed at least partially within the guide member, the pair of needle guides being configured to move between a first position wherein the pair of needle guides are substantially straightened at least partially within the guide member and a second position wherein the pair of needle guides at least partially extend through the one or more openings radially and distally away from both the guide member and the tapered portion, each of the pair of needle guides having a shaft of a needle disposed therein, a deployment angle of each of the needles relative to a longitudinal axis of the guide member is greater than a taper angle of the tapered portion relative to the longitudinal axis of the guide member, wherein upon the pair of needle guides extending radially and distally away relative to both the guide member and the tapered portion, each of the pair of needle guides is noncontiguous with the tapered portion; and

an angle adjustment member movably attached to the guide member, the angle adjustment member having a proximal end and a distal end, the angle adjustment member being configured to move between a retracted position wherein the distal end of the angle adjustment member is positioned proximal to the one or more openings and an extended position where the distal end of the angle adjustment member is selectively positioned distal to the one or more openings with the pair of needle guides extending distally from the distal end of the angle adjustment member so as to deflect the pair of needle guides radially toward the guide member when the pair of needle guides are in the second position.

2. The device of claim 1, wherein the pair of needle guides in the second position extend radially from the guide member between 20 degrees and 60 degrees relative to the longitudinal axis of the guide member.

3. The device of claim 1, wherein the pair of needle guides each comprise an elongate portion, and a self-expanding portion deflected laterally outward from the elongate portion.

4. The device of claim 1, wherein the guide member includes a lumen defined therein extending distally from the proximal end of the guide member toward the distal end of the guide member, wherein the lumen is sized to receive one of the pair of needle guides.

5. The device of claim 1, further including an actuator coupled to the pair of needle guides, the actuator being configured to deploy the pair of needle guides from the guide member through a vessel wall.

6. The device of claim 1, wherein at least one of the needles is detachably coupled to a distal end of one of the pair of needle guides and is configured to resist proximal movement when deployed in a vessel wall.

7. The device of claim 1, wherein the distal end of the angle adjustment member includes a tapered tip portion, the tapered tip portion being configured to move between a low-profile configuration and an expanded configuration.

8. The device of claim 7, wherein the tapered tip portion includes slits radially spaced about the tapered tip portion and extending proximally from a distal end of the tapered tip portion and intermediate portions defined between the slits.

9. A vessel closure device, the device comprising:

a guide member having a proximal end, a stepped distal end, and one or more lumens extending from the proximal end to one or more openings adjacent the distal end, a distalmost end of the device being formed by a tapered portion disposed distal the one or more openings and extending from a distalmost end of the stepped distal end, a distal end of the tapered portion being a distalmost end of the device, a distal end of the tapered portion having a cross-section in a direction transverse to a longitudinal axis of the guide member that is greater than a proximal end of the tapered portion, the stepped distal end having a step extending towards the proximal end with the distalmost end of stepped distal end having a smaller outer diameter than an outer diameter of a portion adjacent the one or more openings, the proximal end of the guide member being mounted to a proximal handle;

a pair of needle guides moveably connected to the guide member and disposed in the one or more lumens, the pair of needle guides being configured to move between a first position, wherein the pair of needle guides are adjacent to the guide member, and a second position wherein the pair of needle guides at least partially extend distally away and radially outward relative to the guide member and the tapered portion at a first angle from the longitudinal axis of the guide member, with the first angle being greater than a taper angle of the tapered portion relative to the longitudinal axis of the guide member, and a peripheral outer surface of the pair of needle guides being spaced apart from the tapered portion without the peripheral outer surface contacting the tapered portion; and

an angle adjustment member slidably attached to the guide member, the angle adjustment member being configured to selectively reduce the first angle of the pair of needle guides by selectively urging the pair of needle guides radially toward the guide member and the tapered portion when the angle adjustment member is in an extended position where a distal end of the angle adjustment member is selectively positioned distal to the one or more openings with the pair of needle guides extending distally from the distal end of the angle adjustment member.

10. The device of claim 9, wherein a distal end of the pair of needle guides is resiliently-biased to extend radially outward from the guide member at the first angle.

11. The device of claim 9, wherein the first angle is 60 degrees.

12. The device of claim 9, wherein the angle adjustment member is configured to selectively reduce the first angle of the needle guides to less than 60 degrees.

13. The device of claim 9, wherein the angle adjustment member concentrically surrounds at least a part of the guide member.

14. The device of claim 9, further including one or more suture securing devices attached to the pair of needle guides, the one or more suture securing devices comprising:

a body having a proximal end, a mid-point, a distal end, and an inner cavity;

a first opening in the proximal end of the body in communication with the inner cavity;

a second opening in the distal end of the body in communication with the inner cavity;

one or more projections defined between elongated slots extending distally from the proximal end of the body, the one or more projections having a fixed end connected to the body and a free end; and

a suture extending through the inner cavity of the body, the body being crimped about the suture such that the suture is mechanically attached to the body;

wherein the one or more projections are moveable between a first configuration wherein the one or more projections are substantially parallel with a longitudinal axis of the body and a second configuration wherein the one or more projections extend radially outwardly from the body such that the one or more suture securing devices can resist proximal movement against a distal surface of a vessel wall.
