Devices, systems, and methods for suturing of body lumens allow the suturing of vascular puncture sites located at the distal end of a percutaneous tissue tract. An elongated articulated foot is inserted through a penetration and actuated extend the foot carrying suturing attachment cuffs. Needles are advanced from the shaft through the vessel wall outside of the penetration and into engagement with the needle cuffs after the foot has been drawn proximally up against the endothelial surface of the blood vessel. The cuffs lockingly engage the needles and can be withdrawn along the needle paths and through the tissue tract to form a loop of suture across the puncture. The articulating foot may be realigned with the shaft and withdrawn proximally through the tissue tract without dilating the tissue tract.
What is claimed is: 1. A suturing device for suturing a vessel through a puncture and a tissue tract, the suturing device comprising: a probe suitable for insertion along the tissue tract and into the vessel through the puncture; at least one penetrator disposed within a portion of said probe, said
What is claimed is: 1. A suturing device for suturing a vessel through a puncture and a tissue tract, the suturing device comprising: a probe suitable for insertion along the tissue tract and into the vessel through the puncture; at least one penetrator disposed within a portion of said probe, said at least one penetrator cooperating with a length of suture, said length of suture including a pre-tied knot disposed about an outer surface of said probe; and an actuator cooperating with said at least one penetrator, said actuator being movable within said probe to deploy said at least one penetrator, said at least one penetrator becoming detached from within said portion of said probe. 2. The suturing device recited in claim 1, further comprising at least one foot movably mounted to said probe. 3. The suturing device recited in claim 2, said probe further comprising a shaft, said at least one movable foot being movably mounted to said shaft. 4. The suturing device recited in claim 1, said at least one penetrator comprising a detachable tip, said detachable tip being detachable from within said first portion of said probe. 5. The suturing device recited in claim 1, said pre-tied knot being disposed to receive an end of said length of suture. 6. The suturing device recited in claim 1, said at least one penetrator being disposed proximal to a distal end of said probe. 7. The suturing device recited in claim 1, said at least one penetrator comprising a hollow needle. 8. A suturing device for suturing a wall of a vessel through a puncture and a tissue tract, the suturing device comprising: a probe suitable for insertion along the tissue tract and into the vessel through the puncture; at least one detachable penetrator disposed within a first portion of said probe, said at least one detachable penetrator being detachable from within said first portion of said probe; an actuator cooperating with said at least one detachable penetrator, said actuator being movable within said probe to deploy said at least one detachable penetrator; and at least one flexible filament cooperating with said at least one detachable penetrator so that at least a portion of said at least one flexible filament is passable through the wall of the vessel and is receivable by a bight of said at least one flexible filament, said at least one flexible filament including a pre-tied knot disposed about an outer surface of said probe. 9. The suturing device recited in claim 8, said at least one penetrator comprising a detachable tip, said detachable tip being detachable from within said first portion of said probe. 10. The suturing device recited in claim 8, said pre-tied knot being disposed to receive an end of said at least one flexible filament. 11. The suturing device recited in claim 10, said pre-tied knot being disposed within a slot formed in an exterior surface of said probe. 12. The suturing device recited in claim 8, said at least one flexible filament comprising a first length of suture extending from said at least one detachable penetrator. 13. The suturing device recited in claim 8, said at least one flexible filament comprising: a first length of suture extending from said at least one detachable penetrator; and a second length of suture extending from a receptacle supported by said probe, said receptacle receiving said at least one detachable penetrator. 14. A suturing device for suturing a body lumen through a puncture and a tissue tract, the suturing device comprising: a probe suitable for insertion along the tissue tract and into the body lumen through the puncture; two needles disposed within a portion of said probe; an actuator cooperating with said two needles, said actuator being movable within said probe to deploy said two needles into the body lumen, a portion of at least one of said two needles detachable from within said portion of said probe upon being disposed within the body lumen, wherein said at least one of said two needles, when deployed, are configured to carry a length of suture through the wall of the body lumen and into the body lumen, said length of suture including a pre-tied knot disposed about an outer surface of said probe. 15. The suturing device recited in claim 14, further comprising at least one foot movably mounted to said probe. 16. The suturing device recited in claim 15, said probe further comprising a shaft, said at least one movable foot being movably mounted to said shaft. 17. The suturing device recited in claim 14, said at least one of said two needles comprising a detachable tip, said detachable tip being detachable from within a first portion of said probe. 18. The suturing device recited in claim 14, said pre-tied knot being disposed to receive an end of said length of suture. 19. The suturing device recited in claim 14, each of said two needles comprising a detachable tip. 20. The suturing device recited in claim 14, at least one of said two needles comprising a hollow needle.
