<p>A suturing assembly (10) is provided which includes a cannula (20) with first (21) and second (22) ends. A first portion (25) adjacent the first end (21) defines a proximal lumen (27) for slidably receiving a needle (50), a first bend (30), and a needle exit aperture (35) at the first bend (30) in communication with the proximal lumen (27). The first lumen (27) and the needle exit aperture (32) define a needle path (P). A second portion (35) is adjacent the second end (22), and defines a distal lumen (37). The cannula (20) defines a second bend (40) between the first bend (30) and the second portion (35). A needle entrance aperture (42) is defined in the second portion (35) in communication with the distal lumen (37) and in line with the needle path (P). The cannula (20) defines a first opening (21a) in the first end (21) in communication with the proximal lumen (27). A needle (50) with a piercing end (51) is slidably disposed within the proximal lumen (27).</p> |
