Abstract

A surgical device for suturing vascular vessels is described, as well as methods for suturing tissue employing the surgical device. The device includes a distal member for insertion into a vascular vessel puncture wound. The distal member contains a suture and needle engaging fitting. At least one needle is advanced through tissue adjacent the puncture wound and into the needle engaging fitting to draw lengths of suture material which can then be used to close the puncture wound.

Claims

1. A method of suturing an opening in a vascular vessel, said method comprising:

inserting a vascular suturing device through the opening in the vascular vessel, said suturing device comprising;

a proximal member having a single needle channel configured to receive a plurality of needles;

a distal member configured to be inserted into the lumen of the vascular vessel, the distal member having a single cavity therein and a length of suture material disposed in the single cavity; and

a connecting member between the proximal and distal members;

distally advancing a first needle of the plurality of needles through the single needle channel, sufficient to pierce a portion of tissue adjacent the opening in the vessel extend into the single cavity of the distal member;

capturing the suture within the single cavity with the first needle, the first needle engaging a first needle engaging fitting connected to the length of suture;

retracting the first needle carrying a first portion of the suture back through the tissue and the single needle channel; and

distally advancing a second needle of the plurality of needles through the single needle channel following retraction of the first needle through the single needle channel to capture a second portion of the suture connected to a second needle engaging fitting, the first needle engaging fitting has a cross-sectional diameter greater than that of the second needle engaging fitting.

2. The method of claim 1 comprising repositioning the suturing device within the lumen and advancing the second needle of the plurality of needles through the single needle channel to the suture within the cavity.

3. The method of claim 2 wherein the suture comprises two needle engaging fittings.

4. The method of claim 3 comprising retracting the second needle of the plurality of needles carrying the second portion of the suture back through the tissue and the single needle channel to leave a loop of suture within the cavity.

5. The method of claim 4 comprising securing the first and second portions of the suture together to promote hemostasis.

6. The method of claim 5 wherein said securing comprises tying the first and second portions of suture together.

7. The method of claim 5 wherein said securing comprises clamping the first and second portions of suture together with a suture clamp.

8. A method of suturing an opening in a vascular vessel, said method comprising:

inserting a vascular suturing device through the opening in the vascular vessel, said suturing device comprising;

a proximal member including an elongate body having a single needle channel therethrough sized to receive at one time a single needle of a plurality of needles therein;

a distal member configured to be inserted into the lumen of the vascular vessel, said member having a receptacle located therein, and a length of suture material being stored in the distal member; and

an intermediate member disposed between the proximal member and the distal member, said intermediate member defining a tissue receiving area and having a first opening providing a passageway to the channel and a second opening providing a passageway into the receptacle;

distally advancing a first needle of the plurality of needles through the needle channel, which is configured to receive only the single needle of the plurality of needles at one time, sufficient to pierce a first portion of tissue adjacent the opening in the vessel and to extend into the cavity of the distal member;

capturing a first portion of the suture within the cavity with the first needle, the first needle engaging a first needle engaging fitting connected to the length of suture;

retracting the first needle carrying the first portion of the suture back through the tissue and the channel; and

distally advancing a second needle of the plurality of needles through the same single needle channel following retraction of the first needle through the single needle channel to capture a second portion of the suture connected to a second needle engaging fitting, the first needle engaging fitting has a cross-sectional diameter greater than that of the second needle engaging fitting.

9. The method of claim 8, wherein the second needle is advanced through the needle channel from a needle cartridge slidably mounted on the proximal member and containing a plurality of needles.

10. The method of claim 9, further comprising retracting the second needle carrying the second portion of the suture back through the tissue and the channel.

11. The method of claim 10, wherein the first needle engaging fitting is disposed proximal to the second needle engaging fitting within the receptacle.

12. A method of suturing an opening in a vascular vessel, said method comprising:

inserting a vascular suturing device through the opening in the vascular vessel, said suturing device comprising;

a proximal member including an elongate body having a needle channel therethrough sized to receive a single needle therein;

a distal member configured to be inserted into the lumen of the vascular vessel, said member having a receptacle located therein, and a length of suture material being stored in the distal member;

an intermediate member disposed between the proximal member and the distal member, said intermediate member defining a tissue receiving area and having a first opening providing a passageway to the channel and a second opening providing a passageway into the receptacle;

advancing a first needle through the needle channel, sufficient to pierce a first portion of tissue adjacent the opening in the vessel and to extend into the cavity of the distal member;

capturing the suture within the cavity with the first needle;

wherein capturing the suture within the cavity with the first needle, comprises the first needle engaging a first needle engaging fitting connected to the length of suture;

retracting the first needle carrying a first portion of the suture back through the tissue and the channel;

advancing a second needle through the needle channel, sufficient to pierce a second portion of tissue adjacent the opening in the vessel and to extend into the cavity of the distal member;

wherein the second needle is advanced through the needle channel from a needle cartridge slidably mounted on the proximal member and containing a plurality of needles, capturing the suture within the cavity with the second needle;

wherein capturing the suture within the cavity with the second needle, comprises the second needle engaging a second needle engaging fitting connected to the length of suture;

wherein the first needle engaging fitting is disposed proximal to the second needle engaging fitting within the receptacle and the first needle engaging fitting has a cross-sectional diameter greater than that of the second needle engaging fitting; and

retracting the second needle carrying a second portion of the suture back through the tissue and the channel.

13. The method of claim 12 comprising securing the first and second portions of the suture together to promote hemostasis.

14. The method of claim 12 wherein said securing comprises tying the first and second portions of suture together.

15. The method of claim 12 wherein said securing comprises clamping the first and second portions of suture together with a suture clamp.
