A surgical device for suturing body lumen is described, as well as methods for suturing tissue employing the surgical device. The device can include a body having a shaft and a foot for insertion into an opening in a body lumen. The body can include tissue ports between the shaft and the foot configured to receive tissue of the body lumen surrounding the opening. The foot can include a suture secured to needle capture devices. Needle can be advanced within the shaft, through tissue within the tissue ports, and into the needle capture devices. The needle capture devices cuffs can then be withdrawn, thereby harvesting the suture, which can then be used to close the opening in the body lumen.
1. A suturing device configured to close an opening in a body lumen, the suturing device comprising: a shaft having a distal end, a proximal end, and a guidewire lumen extending from the proximal end toward the distal end, the distal end of the shaft being defined by the distal most surface of the s
1. A suturing device configured to close an opening in a body lumen, the suturing device comprising: a shaft having a distal end, a proximal end, and a guidewire lumen extending from the proximal end toward the distal end, the distal end of the shaft being defined by the distal most surface of the shaft;a first needle exit opening extending through the distal end of the shaft;a second needle exit opening extending through the distal end of the shaft;a foot member secured to the distal end of the shaft, the guidewire lumen extending from the shaft through the foot member, a proximal end of the foot member having a flared portion and a guide body portion extending distally of the flared portion, the flared portion extending radially outwardly of an outward surface of the shaft and an outward surface of the guide body;a first needle capture device removably secured to the foot member;a second needle capture device removably secured to the foot member; andat least one length of suture removably secured to the foot member, the at least one length of suture having a first end and a second end, the first end being secured to the first needle capture device and the second end being secured to the second needle capture device. 2. The suturing device of claim 1, further comprising at least one tissue port separating the first needle capture device from the first needle exit opening and the second needle capture device from the second needle exit opening, the at least one tissue port being configured to receive wall tissue of the body lumen. 3. The suturing device of claim 2, further comprising an actuator configured to move the foot member from a first configuration adjacent the distal end of the shaft to a deployed configuration distally separated from the distal end of the shaft, thereby opening the at least one tissue port. 4. The suturing device of claim 2, further comprising a pair of needles configured to be advanced from through the shaft, out of the first and second needle exit openings, across the at least one tissue port, and into the first and second needle capture devices. 5. The suturing device of claim 1, further comprising a spinal member connecting the foot member to the shaft. 6. A suturing device, configured to close an opening in a body lumen, the suturing device comprising: a shaft having a distal end, a proximal end, and a guidewire lumen extending from the proximal end toward the distal end, the distal end of the shaft being defined by the distal most surface of the shaft;a first needle exit opening extending through the distal end of the shaft;a second needle exit opening extending through the distal end of the shaft;a foot member secured to the distal end of the shaft, the guidewire lumen extending from the shaft through the foot member;a first needle capture device removably secured to the foot member;a second needle capture device removably secured to the foot member; and at least one length of suture removably secured to the foot member within a suture lumen, the at least one length of suture having a first end and a second end, the first end being secured to the first needle capture device and the second end being secured to the second needle capture device, the suture lumen extending at least partially around the guidewire lumen,wherein the suture lumen receives the entire length of the at least one length of suture. 7. The suturing device of claim 6, further comprising at least one tissue port separating the first needle capture device from the first needle exit opening and the second needle capture device from the second needle exit opening, the at least one tissue port being configured to receive wall tissue of the body lumen. 8. The suturing device of claim 7, further comprising a pair of needles configured to be advanced from through the shaft, out of the first and second needle exit openings, across the at least one tissue port, and into the first and second needle capture devices. 9. The suturing device of claim 6, further comprising a spinal member connecting the foot member to the shaft. 10. The suturing device of claim 9, wherein the spinal member comprises a width equal to about a diameter of a guide body portion of the foot member. 11. The suturing device of claim 9, further comprising a pair of tissue ports disposed between the shaft and the foot member at the spinal member. 12. The suturing device of claim 9, wherein the spinal member forms a single circumferential tissue port. 13. The suturing device of claim 6, wherein the suture lumen extends 180 degrees around the guidewire lumen. 14. The suturing device of claim 6, further comprising a handle. 15. A suturing device, configured to close an opening in a body lumen, the suturing device comprising: a shaft having a distal end, a proximal end, and a guidewire lumen extending from the proximal end toward the distal end, the distal end of the shaft being defined by the distal most surface of the shaft;a first needle exit opening extending through the distal end of the shaft;a second needle exit opening extending through the distal end of the shaft;a foot member secured to the distal end of the shaft, the guidewire lumen extending from the shaft through the foot member, the foot includes a flared portion and a guide body portion, the flared portion extending outwardly greater than the guide body portion and the shaft;a first needle capture device removably secured to the foot member;a second needle capture device removably secured to the foot member; andat least one length of suture removably secured to the foot member within a suture lumen, the at least one length of suture having a first end and a second end, the first end being secured to the first needle capture device and the second end being secured to the second needle capture device, the suture lumen extending at least partially around the guidewire lumen. 16. The suturing device of claim 15, further comprising a needle actuation handle selectively engageable with the shaft. 17. The suturing device of claim 16, wherein the needle actuation handle is secured to a first needle and a second needle. 18. The suturing device of claim 16, wherein the shaft comprises a receptacle disposed at the proximal end of the shaft, the needle actuation handle being configured to be received within the receptacle.
