Abstract:
1. A method of suturing a blood vessel, comprising: advancing a suturing device having an elongated body through a tissue tract, and through an opening in the blood vessel, the tissue tract being situated at a non-perpendicular angle relative to a longitudinal axis of the blood vessel and the suturing device having a longitudinal axis; extending a first arm at a non-perpendicular angle from the distal end of the elongated body, the first arm having a needle receiving portion thereon; extending a second arm at a non-perpendicular angle from the distal end of the elongated body, the second arm having a needle receiving portion thereon, wherein the first and second arms extend longitudinally within the blood vessel while the elongated body is positioned within the tissue tract; and advancing a first needle from a first position adjacent to the elongated body to a second position spaced obliquely outwardly from the first position adjacent to the elongated body, a first needle tip of the first needle being spaced apart from the longitudinal axis a first distance in the first position and a second distance in the second position, the first distance being smaller than the second distance; and advancing a second needle from a third position adjacent to the elongated body to a fourth position spaced outwardly from the third position adjacent to the elongated body, a second needle tip of the second needle being spaced apart from the longitudinal axis a third distance in the third position and a fourth distance in the fourth position, the third distance being smaller than the fourth distance and the second distance and the fourth distance being different.
