A suturing device (2) for suturing a portion of biological tissue (130) includes a needle (90) attached to a suture (100), a needle holder (34) that releasably holds the needle (90), and a needle driver (110) adapted to be advanced and retracted substantially parallel to a longitudinal axis of the suturing device (2). A distal needle holder (34) adapted to releasably hold the needle (90) is positioned in a distal position relative to the portion of biological tissue (130) and a distal end of the needle driver (110) is positioned in a proximal position relative to the portion of biological tissue (130). The needle (90) is positioned in either the proximal position or the distal position. The needle driver (110) is moved longitudinally in a first direction along a path substantially parallel to the longitudinal axis such that the needle (90) and suture (100) pass through the portion of biological tissue (130), thereby forming a suture incision through which the suture (100) passes. By repeating the above-described processes, a series of stitches is thereby formed. |
