Abstract

An improved suturing device and method is provided. The suturing device is of the type including a guide body and means on the guide body for translating at least one needle relative to the guide body. The suturing device is improved by providing a rotatable sleeve disposed over at least a distal portion of the guide body to facilitate introduction of the device to a puncture site.

Claims

1. A suturing device comprising:

a guide body;

a translating mechanism which translates at least one needle relative to the guide body;

a rotatable sleeve disposed over at least a distal portion of the guide body, wherein the rotatable sleeve is operably attached to the guide body such that the rotatable sleeve may rotate about the guide body while substantial axial movement of the rotatable sleeve relative to the guide body is prevented.

2. A suturing device as in claim 1, wherein the rotatable sleeve is a rigid cylinder having a length in the range from 30 mm to 200 mm and a diameter in the range from 3 mm to 15 mm.

3. A suturing device as in claim 1, further comprising a flexible tube extending distally from the guide body, wherein the flexible tube includes a proximal end, a distal end, and a guide wire lumen extending proximally from the distal end and terminating in an exit port between the proximal and distal ends.

4. A suturing device as in claim 3, wherein the flexible tube has a length in the range from about 20 cm to 40 cm, and further comprising a side port which is located at about 5 cm to 20 cm from the proximal end.

5. A suturing device as in claim 4, wherein the flexible tube has an outside diameter in the range from about 2 mm to 10 mm.

6. A suturing device as in claim 3, wherein the flexible tube further includes a central lumen extending distally from the proximal end, the central lumen being sized to house the needle.

7. A suturing device as in claim 1, further comprising a stopping mechanism to selectively prevent rotation of the sleeve.

8. A suturing device as in claim 7, wherein the stopping mechanism comprises a handle attached to the guide body, the handle having at least one detent for engaging a groove in the sleeve.

9. A suturing device as in claim 1, further comprising at least one blood detection lumen passing through the guide body.

10. A suturing device as in claim 9, further comprising a suture lumen passing through the guide body, said suture lumen housing a length of suture.

11. A suturing device comprising:

a guide body;

a translating mechanism to translate at least one needle relative to the guide body;

a flexible tube having a proximal end connected to the guide body, a distal end, and a guide wire lumen initiating at the distal end and terminating in a guide wire exit port between the proximal end and the distal end; and

a sleeve rotatably disposed about the guide body.

12. A suturing device as in claim 11, further comprising a handle attached to the guide body, the handle having at least one detent for engaging a groove in the sleeve.

13. A suturing device as in claim 11, wherein the flexible tube has a length in the range from about 20 cm to 40 cm, and wherein the exit port is located at about 5 cm to 20 cm from the proximal end.

14. A suturing device as in claim 11, wherein the flexible tube has an outside diameter in the range from about 2 mm to 10 mm.

15. A suturing device as in claim 11, wherein the flexible tube includes means for directing a proximally advanced guide wire through the exit port.

16. A suturing device as in claim 11, wherein the rotatable sleeve is a rigid cylinder having a length in the range from 30 mm to 200 mm and a diameter in the range from 3 mm to 15 mm.

17. A suturing device as in claim 11, further comprising at least one blood detection lumen passing through the guide body.

18. A suturing device as in claim 17, further comprising a suture lumen passing through the guide body, said suture lumen housing a length of suture.

19. A suturing device comprising:

a guide body having a proximal end, a distal end, and an internal lumen;

a needle guide having a proximal end attached to the distal end of the guide body and a distal end having at least two needle guide channels, said needle guide further including a proximal region and a distal region, wherein the needle guide channels are disposed in the distal region and wherein the proximal region includes a recessed portion for receiving a section of tissue;

a pair of needles;

a length of suture having two ends, with each end attached to one of the needles and with at least a portion of the remaining length of suture passing through the internal lumen of the guide body;

a shaft reciprocatably mounted within the guide body and carrying the needles to reciprocate the needles within the needle guide channels; and

a pair of receiving channels in the guide body which are separate from the internal lumen, wherein the pair of needles are operably connected to the shaft such that reciprocation of the shaft draws the needles into the receiving channels and draws the length of suture from the internal lumen.

20. A suturing device as in claim 19, further comprising a blood detection lumen which is separate from the internal lumen.

21. A method for suturing a puncture site in a blood vessel wall disposed at the distal end of a percutaneous tissue tract, said method comprising:

introducing a suturing device having a guide body and a flexible tube distally extending from the guide body to the puncture site so that the guide body lies within the tissue tract and the flexible tube lies within the blood vessel lumen;

drawing a pair of needles with a length of suture therebetween from the flexible tube through the blood vessel wall adjacent the puncture and outward through the tissue tract, wherein at least a portion of the length of suture extending between the pair of needles passes through a lumen in the guide body and is located outside the patient during the introduction step, wherein the length of suture is pulled back through the guide body lumen during the drawing step, and wherein the needles are received into receiving channels within the guide body which are separate from the lumen; and

securing a loop in the suture to close the punctures.

22. A method as in claim 21, wherein the suturing device includes a sleeve rotatably disposed about the guide body, and further comprising rotating the sleeve relative to the guide body while introducing the guide body into the puncture site.

23. A method as in claim 21, wherein the introducing step further comprises inserting the flexible tube over a guide wire and advancing the tube over the guide wire until the guide wire exits an exit port in the flexible tube.

24. A method as in claim 23, further comprising withdrawing the guide wire from the puncture site prior to introducing the guide body into the tissue tract.

25. A method as in claim 21, further comprising positioning the suturing device by observing blood within a marker lumen in the guide body having a side port between the flexible tube and the distal end of the guide body.

26. A method as in claim 21, further comprising withdrawing the suturing device from the puncture site prior to securing the loop.

27. A method as in claim 21, further comprising inhibiting deployment of the needle during the introducing step.
