         8 . The surgical device of  claim 1 , wherein the seal anchor member is configured for insertion into an incision during a laparoscopic surgical procedure, and wherein the at least three lumens are configured to inhibit the escape of insufflation gases from within a body cavity. 
     
     
         9 . The surgical device of  claim 8 , wherein the at least three lumens are configured to inhibit the escape of insufflation gases from within a body cavity with or without instrumentation being inserted therein. 
     
     
         10 . A surgical device comprising:
 a compressible seal anchor member defining a longitudinal axis, the seal anchor member including a leading end defining a distal surface, a trailing end defining a proximal surface, and an intermediate portion between the leading and trailing ends, each of the leading and trailing ends having a diameter that is greater than a diameter of the intermediate portion when the seal anchor member is in an at-rest condition,   the seal anchor member defining a plurality of ports extending through the leading end, the intermediate portion and the trailing end, at least two of the plurality of ports being configured for substantially sealed reception of an instrument therein, wherein at least two ports are straight within the seal anchor member and are non-parallel relative to each other and to the longitudinal axis when the seal anchor member is in the at-rest condition, and wherein the at least two ports, when the seal anchor member is viewed from the side, cross one another such that a pair of surgical instruments inserted within the at least two ports cross one another within the seal anchor member in the absence of a force being exerted on the pair of surgical instruments.   
     
     
         11 . The surgical device of  claim 10 , wherein the proximal and distal surfaces are arcuate. 
     
     
         12 . The surgical device of  claim 10 , wherein the compressible material comprises at least one of a foam and a gel. 
     
     
         13 . The surgical device of  claim 10 , wherein a position of the plurality of ports relative to each other is adjustable by a force exerted by at least one instrument when the instrument is within one of the plurality of ports. 
     
     
         14 . The surgical device of  claim 10 , wherein the seal anchor member is adapted to transition between a compressed condition to facilitate at least partial insertion of the seal anchor member within an incision in an abdominal wall of a patient, and an inserted condition to facilitate securing of the seal anchor member within the incision and in sealing relation with tissue surfaces defining the incision. 
     
     
         15 . The surgical device of  claim 10 , wherein the seal anchor member defines a substantially hour-glass shape. 
     
     
         16 . The surgical device of  claim 10 , wherein the seal anchor member is configured for reception of a camera therethrough. 
     
     
         17 . The surgical device of  claim 10 , wherein the seal anchor member is configured for insertion into an incision during a minimally invasive surgical procedure, the seal anchor member inhibiting the escape of insufflation gases from within a body cavity. 
     
     
         18 . A surgical device configured for insertion into an incision during a minimally invasive surgical procedure and to inhibit the escape of insufflation gases from within a body cavity, the surgical device comprising:
 a seal anchor member defining a longitudinal axis, the seal anchor member including a leading end defining an arcuate distal surface and a trailing end defining an arcuate proximal surface, the seal anchor member defining a substantially hour-glass shape when the seal anchor member is in an at-rest condition,   the seal anchor member defining at least first, second and third lumens extending through the trailing and leading ends from the proximal surface to the distal surface, each one of the first, second and third lumens being configured for substantially sealed reception of an instrument therein,   wherein, when surgical instruments are in use within the lumen of the seal anchor member, each one of the first, second and third lumens define a longitudinal axis that is straight and that is non-parallel relative to each other, wherein the longitudinal axis of the first lumen is parallel relative to the longitudinal axis of the seal anchor member and is configured for reception of a camera therein, and wherein the longitudinal axes of the second and third lumens are non-parallel relative to the longitudinal axis of the seal anchor member and cross over each other when the seal anchor member is viewed from a side, the second and third lumens configured for reception of a pair of surgical instruments therein.   
     
     
         19 . The surgical device of  claim 18 , wherein, when the seal anchor member is viewed from the side, the longitudinal axes of the second and third lumens cross one another such that, in the absence of a radial force being exerted on a pair of surgical instruments inserted through the second and third lumen, the pair of surgical instruments cross one another within the seal anchor member. 
     
     
         20 . The surgical device of  claim 18 , wherein the seal anchor member is formed from a material that enables the seal anchor member to transition between a first condition in which at least a portion of the seal anchor member is insertable within an incision in an abdominal wall, and a second condition in which at least a portion of the seal anchor member expands so as to be secured within the incision and so as to be in sealing relation with tissue surfaces defining the incision.
