FOAM PORT INTRODUCTION SYSTEM INCLUDING DILATOR
A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity, comprising a compressible seal anchor member including a leading end configured for insertion within the tissue tract and a trailing end configured to remain outside of the tissue tract, the compressible seal anchor member having at least one longitudinal port extending between the leading and trailing ends for substantially sealed reception of an object therein, the compressible seal anchor member including a bore for receipt of a dilator.
1 . A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity, comprising:
a compressible seal anchor member including a leading end configured for insertion within the tissue tract and a trailing end configured to remain outside of a tissue tracts, the compressible seal anchor member having at least one longitudinal port extending between the leading and trailing ends for substantially sealed reception of an object therein, the compressible seal anchor member including a bore for receipt of a dilator.
2 . The surgical apparatus of claim 1 , wherein the compressible seal anchor has an outer surface between the leading and trailing ends, the outer surface configured to contact the tissue tract.
3 . The surgical apparatus of claim 2 , wherein the compressible seal anchor member has a first volume without the dilator being received in the bore and a second volume with the dilator being received within the bore, the first volume being less than the second volume.
4 . The surgical apparatus of claim 3 , wherein the compressible seal anchor member may be more easily inserted into the tissue tract when the dilator is not received within the bore due to its lesser volume.
5 . The surgical apparatus of claim 2 , wherein the compressible seal anchor member provides a first radial pressure without the dilator being received in the bore and a second radial pressure with the dilator being received within the bore, the second radial pressure being greater than the first radial pressure.
6 . The surgical apparatus of claim 5 , wherein the compressible seal anchor member provides for improved sealing with, and retention within, the tissue tract when the dilator is received within the bore due to the greater radial pressure.
7 . The surgical apparatus of claim 1 , wherein the object is a cannula, and the at least one longitudinal port extending between the leading and trailing ends of the compressible seal anchor member provides for substantially sealed reception of the cannula therein.
8 . The surgical apparatus of claim 1 , wherein the compressible seal anchor member has a first degree of compressibility and the dilator has a second degree of compressibility.
9 . The surgical apparatus of claim 8 , wherein the first degree of compressibility is greater than the second degree of compressibility.
10 . The surgical apparatus of claim 1 , wherein the compressible seal anchor member is formed of a foam material.
11 . The surgical apparatus of claim 1 , wherein the dilator is substantially rigid.
