1. An instrument for manipulating anatomical tissue, comprising:
- an elongated barrel having a distal end and a proximal end;
a handle coupled to the proximal end;
a first connecting member coupled to a distal end of said barrel;
a first end effector extending from said first connecting member, said first end effector having a longitudinal axis that is offset from and substantially parallel to a longitudinal axis of said barrel;
a second connecting member coupled to a distal end of said barrel, said second connecting member being coupled to said barrel to move arcuately with respect to said barrel; and
a second end effector extending from said second connecting member, said second end effector having a longitudinal axis that is offset from a longitudinal axis of said barrel.

Abstract
An instrument for manipulating anatomical tissue and a method of using the instrument. A barrel has two drivers therein which can be manipulated from a proximal end of the barrel. The end effector of each driver are offset from a shaft by a transverse arm. In an insertion position, the end effectors are confined within the diametrical dimension of the barrel at a distal end thereof. After insertion, the end effectors can be manipulated by rotationally or arcuately moving the shafts to extend beyond the diametrical dimension of the barrel to provide a large working span in which a tissue procedure can be accomplished.

24. A method of suturing anatomical tissue using a length of suture material attached to a needle, said method comprising the steps of:
-
introducing a distal end of a barrel into an area proximate the anatomical tissue; grasping the needle with driver needle holding members, said driver needle holding members being disposed on a driver connecting member coupled to a distal end of the barrel and having a longitudinal axis that is offset from and substantially parallel to a longitudinal axis of the barrel; rotating the driver connecting member in a first direction to cause the needle to move in an arcuate path and to cause a tip of the needle to penetrate the anatomical tissue; and grasping the needle with a needle catcher, the needle catcher including a catcher connecting member coupled to a distal end of said barrel, and catcher needle holding members disposed on the catcher connecting member and having a longitudinal axis that is offset from a longitudinal axis of the catcher shaft, said catcher connecting member being coupled to the barrel to move arcuately with respect to the barrel. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31)

32. A method of suturing anatomical tissue using a length of suture material attached to a needle, said method comprising the steps of:
-
grasping the needle with driver needle holding members, the driver needle holding members being disposed on a driver connecting member extending from a distal end of an elongate barrel; rotating the driver connecting member in a first direction to cause a tip of the needle to penetrate the anatomical tissue; grasping the needle with catcher needle holding members mounted on a catcher connecting member extending from a distal end of the barrel; releasing the needle from the driver needle holding members; and moving the catcher connecting member through an arcuate path to pull the needle entirely through the anatomical tissue; wherein all of the above steps are accomplished automatically in response to movement of a single proximal control. - View Dependent Claims (33)

36. An instrument for manipulating anatomical tissue comprising:
-
an elongated barrel having a distal end and a proximal end; a handle coupled to said proximal end; a first driver comprising a first shaft extending from the distal end of said barrel, a first connecting member disposed on a distal end of said first shaft, and a first end effector extending from said first connecting member, said first end effector having a longitudinal axis that is offset from and substantially parallel to a longitudinal axis of said first shaft; and a second driver comprising a second shaft extending from the distal end of said barrel, a second connecting member disposed on a distal end of said second shaft, and a second end effector extending from said second connecting member, said second end effector having a longitudinal axis that is offset from a longitudinal axis of said second shaft, said second shaft being arcuately movable through said barrel.
