A generally C-shaped trocar provides increased work space between the hands of the surgeon as well as S-shaped laparoscopic instruments placed through the trocar when laparoscopic instrument-trocar units are placed through the umbilicus. In order to facilitate retraction of intra-abdominal structures during a laparoscopic procedure, an angulated needle and thread with either one-or two sharp ends is provided. Alternatively, an inflatable unit having at least one generally C-shaped trocar incorporated within the unit's walls can be placed through the umbilicus following a single incision. Generally S-shaped laparoscopic instruments may be placed through the generally C-shaped trocars to facilitate access to intra-abdominal structures. ## Claims ### Claim at position 1 1-27. (canceled) ### Claim 28 A cannula holder comprising: a perimetric wall defining a longitudinal axis and having a first end and a second end, wherein the first end is open and wherein said first end and said second end are each transversed by said axis; and a transverse plate member connected to at least a part of said second end, said transverse plate member extending generally transversely to said axis and including a rigid section attached to said transverse plate member, said transverse plate member having a plurality of passageways traversable by respective cannulas, said passageways being spaced from one another. ### Claim 29 (depends on 28) The cannula holder of claim 28, wherein said cannula holder is at least one of inflatable, deflectable or collapsible. ### Claim 30 (depends on 28) The cannula holder of claim 28, wherein at least one of said passageways extends from an upper surface of said transverse plate member to a lower surface thereof. ### Claim 31 (depends on 28) The cannula holder of claim 28, further comprising a one-way valve positioned in at least one of said passageways. ### Claim 32 (depends on 28) The cannula holder of claim 28, at least one of the plurality of said passageways being preformed. ### Claim 33 (depends on 28) The cannula holder of claim 28, further comprising at least one cannula spaced from said perimetric wall. ### Claim 34 (depends on 28) The cannula holder of claim 28, further comprising at least one cannula coupled to said perimetric wall via a connector. ### Claim 35 (depends on 28) The cannula holder of claim 28, further comprising at least one cannula disposed within said perimetric wall. ### Claim 36 (depends on 28) The cannula holder of claim 28, wherein at least one of said passageways extends from said first end to said second end. ### Claim 37 (depends on 36) The cannula holder of claim 36, further comprising an additional cannula disposed radially outside of and spaced from said perimetric wall. ### Claim 38 (depends on 28) The cannula holder of claim 28, wherein the plurality of said passageways is one passageway defined by the perimetric wall. ### Claim 39 (depends on 28) The cannula holder of claim 28, wherein the rigid section is positioned on the periphery of the transverse plate member wall. ### Claim 40 A cannula holder comprising: a perimetric wall defining a longitudinal axis and having a first end and a second end, wherein the first end is open and wherein said first end and said second end are each transversed by said axis; a transverse plate member attached to at least a part of said second end, said transverse plate member extending generally transversely to said axis and including a rigid section attached to said transverse plate member, the rigid section configured to add stability to the transverse plate member; and at least one passageway extending through the transverse plate member and configured to have a cannula extending therethrough. ### Claim 41 (depends on 40) The cannula holder of claim 40, the at least one passageway being preformed. ### Claim 42 (depends on 40) The cannula holder of claim 40, wherein said cannula holder is at least one of inflatable, deflectable or collapsible. ### Claim 43 (depends on 40) The cannula holder of claim 40, further comprising at least one cannula spaced from said perimetric wall. ### Claim 44 A cannula holder comprising: a perimetric wall having a longitudinal axis and a first end and a second end, wherein the first end is open and wherein said first end and said second end are each transversed by said axis; and a transverse member connected to at least a part of said second end, said transverse plate member extending generally transversely to said axis and including a rigid section inserted in said transverse member, said transverse plate traversable by at least one cannula by a passageway formed therethrough. ### Claim 45 (depends on 44) The cannula holder of claim 44, further comprising at least one cannula, wherein the at least one cannula is two or more cannulas, each cannula passing through a respective passageway through the transverse member. ### Claim 46 (depends on 44) The cannula holder of claim 44, the passageway being preformed. ### Claim 47 (depends on 44) The cannula holder of claim 44, wherein said cannula holder is at least one of inflatable, deflectable or collapsible. ### Claim 48 (depends on 44) The cannula holder of claim 44, further comprising at least one cannula spaced from said perimetric wall.
