1. A system for stabilizing tissue comprising:
- a tissue contact member having a surface adapted to contact the tissue and temporarily maintain the tissue in a relatively immobilized state; and
a maneuverable arm attached to said tissue contact member, said maneuverable arm including an articulating joint formed by a link having a male articulating surface composed of angled teeth and a female articulating surface having angled trenches adapted to receive said angled teeth, wherein said articulating joint moves in one degree of freedom directed by said angled teeth sliding against said angled trenches.

67. A maneuverable arm adapted to position a surgical tool mounted at a distal end thereof in a variety of orientations, said maneuverable arm comprising:
at least one articulating joint formed by a link having a male articulating surface composed of angled teeth and a female articulating surface having angled trenches adapted to receive said angled teeth, wherein said articulating joint moves in one degree of freedom directed by said angled teeth sliding against said angled trenches.
- 98. A tensioning mechanism for applying tension to a cable passing through a maneuverable surgical instrument having at least one articulating joint through which the cable passes, said tensioning mechanism comprising a screw mechanism and a knob, said screw mechanism having a first threaded component having a first set of threads and a second threaded component having a second set of threads adapted to mate with said first set of threads, said first threaded component being fixed to said cable and said knob being adapted to torque said second threaded component with respect to said first threaded component.

104. A device for stabilizing tissue within a patient'"'"'s body comprising:
-
a manifold base having a substantially hollow interior adapted to be develop a negative pressure therein;
at least one tissue contact member extending outwardly from said manifold base and being fluidly connected therewith, each of said at least one tissue contact having a thin compliant seal extending around a perimeter of a bottom surface of the contact member. - View Dependent Claims (105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127, 129, 130, 131, 132, 133, 134, 135, 136, 137, 140, 141, 142, 143, 144)

128. A device for providing additional stabilization to tissue already in contact with a primary stabilization member, said device comprising:
-
at least one tissue contact member adapted to be placed on the tissue in an area bounded by primary tissue contact members; and
a connecting member extending from said at least one tissue contact member and adapted to be hand held or fixed to a relatively immovable object.

-
138. A system for stabilizing tissue within a patient'"'"'s body comprising:
-
a primary tissue contact member having at least a pair of primary contact members adapted to contact the tissue and straddle a target site thereon;
a primary connecting member extending from said primary tissue contact member, said connecting member adapted to be fixed to a relatively stationary object to impart added stability to said primary tissue contact member;
a secondary tissue contact member adapted to be placed on the tissue in an area straddled by said primary contact members; and
a secondary connecting member extending from said secondary tissue contact member and adapted to be hand held or fixed to a relatively immovable object.

-
139. A method of stabilizing tissue at a location of a target site at which an operative procedure is to be performed, while tissue outside of the location remains in motion, said method comprising:
-
contacting the tissue in the vicinity of the location with a primary stabilizing instrument to stabilize the general vicinity of the location; and
contacting the tissue in a location between the location where the primary stabilizing instrument contacts the tissue and the target site, to further stabilize the target site.
