A device for suturing an opening in a tissue, having an elongated shaft, at least two arms movable to a deployed positioning which the arms are non-perpendicular to the shaft, the arms having needle receiving portions; and needles advanceable longitudinally along the shaft toward the needle receiving portions, the needles exiting through side walls of the shaft at a location proximal to the arms.
1. An apparatus for suturing a puncture in a blood vessel, comprising: an elongated body;a first arm movably connected to the elongated body, the first arm being selectively movable between a retracted position and an extended position, the first arm being positioned in a generally anterior directio
1. An apparatus for suturing a puncture in a blood vessel, comprising: an elongated body;a first arm movably connected to the elongated body, the first arm being selectively movable between a retracted position and an extended position, the first arm being positioned in a generally anterior direction relative to the elongated body in the extended position;a second arm movably connected to the elongated body, the second arm being selectively movable between a retracted position and an extended position, the second arm being positioned in a generally posterior direction relative to the elongated body in the extended position;at least one needle being selectively extendable from the elongated body to engage at least one needle receiving portion in at least one of the first arm and the second arm. 2. The device of claim 1, wherein the arms are independently deployable. 3. The device of claim 1, further comprising: a first deployment linkage connected to the first arm; and a second deployment linkage connected to the second arm. 4. The device of claim 3, wherein each deployment linkage comprises a member that is pulled proximally to deploy one of the arms, and is pushed distally to move the arm to the compact position. 5. The device of claim 3, wherein each deployment linkage comprises a wire. 6. The device of claim 1, further comprising: a pivot stop on the distal end of the elongated shaft, wherein the pivot stop limits rotation of the arms when they reach the deployed position. 7. The device of claim 6, wherein the at least two arms comprise an anterior arm and a posterior arm, wherein the anterior arm has an extension portion that contacts the pivot stop when the anterior arm is in its deployed position, and wherein the posterior arm has a stop surface that contacts the pivot stop when the posterior arm is in its deployed position. 8. An apparatus for suturing a puncture in a blood vessel, comprising: an elongated body;a first arm movably connected to the elongated body, the first arm being selectively movable between a retracted position and an extended position, the first arm being rotatable from the retracted position to the extended position through a first angle;a second arm movably connected to the elongated body, the second arm being selectively movable between a retracted position and an extended position, the second arm being rotatable from the retracted position to the extended position through a second angle, the second angle being greater than the first angle;at least one needle being selectively extendable from the elongated body to engage at least one needle receiving portion in at least one of the first arm and the second arm. 9. The apparatus of claim 8, wherein one needle is adapted to be connected to a first end of a length of suture, the suture having a second end and a bight between the first and second ends, the bight being prearranged on the elongate body to define a pre-tied knot when the first end of the suture passes through the bight. 10. The apparatus of claim 8, wherein the elongated body is sufficiently rigid to maintain alignment of the first needle with the first arm and the second needle with the second arm, respectively. 11. The apparatus of claim 8, wherein the first and second end portions of the suture have cuffs disposed thereon. 12. An apparatus for suturing a puncture in a blood vessel, comprising: an elongated body having a longitudinal axis;a first arm movably connected to the elongated body, the first arm being selectively movable between a retracted position and an extended position, the first arm being oriented at a non-perpendicular angle relative to the longitudinal axis when the first arm is in the extended position;a second arm movably connected to the elongated body, the second arm being selectively movable between a retracted position and an extended position, the second arm being oriented at a non-perpendicular angle relative to the longitudinal axis when the first arm is in the extended position, the second arm also being oriented generally parallel to the first arm when the first arm and second arm are in the extended positions;at least one needle being selectively extendable from the elongated body to engage at least one needle receiving portion in at least one of the first arm and the second arm. 13. The device of claim 12, wherein the at least two arms comprise: a first arm that is pivoted less than 90 degrees to the longitudinal axis of the elongated shaft when in the deployed position; and a second arm that is pivoted more than 90 degrees to the longitudinal axis of the elongated shaft when in the deployed position. 14. The device of claim 12, further comprising: a first deployment linkage connected to the first arm; and a second deployment linkage connected to the second arm. 15. The device of claim 14, wherein each deployment linkage comprises a member that is pulled proximally to deploy one of the arms, and is pushed distally to move the arm to the compact position. 16. The device of claim 14, wherein each deployment linkage comprises a wire. 17. The device of claim 12, further comprising a pivot stop on the distal end of the elongated shaft, wherein the pivot stop limits rotation of the arms when they reach the deployed position. 18. The device of claim 17, wherein the at least two arms comprise an anterior arm and a posterior arm, wherein the anterior arm has an extension portion that contacts the pivot stop when the anterior arm is in its deployed position, and wherein the posterior arm has a stop surface that contacts the pivot stop when the posterior arm is in its deployed position. 19. An apparatus for suturing a puncture in a blood vessel, comprising: an elongated body having a first side wall opening and a second side wall opening, the second sidewall opening being longitudinally offset from the first side wall opening;a first arm movably connected to the elongated body, the first arm being selectively movable between a retracted position and an extended position, the first arm being positioned in a generally anterior direction relative to the elongated body in the extended position;a second arm movably connected to the elongated body, the second arm being selectively movable between a retracted position and an extended position, the second arm being positioned in a generally posterior direction relative to the elongated body in the extended position;a first needle being selectively extendable from the elongated body through the first side wall opening and toward the first arm when the first arm is in the extended position; anda second needle being selectively extendable from the elongated body through the second side wall opening and toward the second arm when the second arm is in the extended position. 20. The apparatus of claim 19, wherein the elongated body has a longitudinal axis, the first needle extends from the first side wall opening at a first angle relative to the longitudinal axis, and the second needle extends from the second side wall opening at a second angle relative to the longitudinal axis, the second angle being greater than the first angle.
