A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity. The apparatus may include a seal anchor member comprising a compressible material. The seal anchor member may be adapted to transition between a first condition for insertion of at least a portion of the seal anchor member within a tissue tract and a second condition to facilitate a securing of the seal anchor member within a tissue tract and in substantial sealed relation with tissue surfaces defining a tissue tract. The seal anchor member may have proximal and distal ends and may define at least one port extending between the proximal and distal ends, the at least one port being adapted for the reception of an object whereby compressible material defining the at least one port is adapted to deform to establish a substantial sealed relation with the object. The at least one port may include an undercut to reduce the likelihood of leaks therethrough.
A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity, which comprises:
A seal anchor member formed from a foam material, the member being configured and dimensioned to be compressed for insertion into an incision and, once inserted, to expand so as to be secured within and seal against the incision, the seal anchor member defining at least one port extending generally longitudinally between proximal and distal surfaces of the seal anchor member, the at least one port being adapted for scaled reception of a surgical object, wherein the at least one port defines at least one that engages an outer surface of an instrument inserted therethrough.
A seal anchor member formed from a foam material, the member being configured and dimensioned to be compressed for insertion into an incision and, once inserted, to expand so as to be secured within and seal against the incision, the seal anchor member defining at least one port extending generally longitudinally between proximal and distal surfaces of the seal anchor member, the at least one port being adapted for scaled reception of a surgical object, wherein the at least one port defines a first diameter along at least a first portion of its length and defines a second diameter along at least a second portion of its length.
