Foam port and introducer assembly
First Claim
1. A surgical portal and introducer assembly, which comprises:
- an introducer defining a longitudinal axis and having a longitudinal passageway, the introducer insertable through an opening in tissue, wherein the introducer has a first end and a second end, the first end having a first outer diameter and the second end having a second outer diameter that is less than the first outer diameter;
a portal member positionable within the longitudinal passageway of the introducer, the portal member adapted for positioning within a tissue tract and having at least one longitudinal port for passage of a surgical object, the portal member comprising a compressible material and being adapted to transition between a first expanded condition to facilitate securing of the portal member within the tissue tract and in substantial sealed relation with tissue surfaces defining the tissue tract and a second compressed condition to facilitate at least partial insertion of the portal member within the tissue tract; and
an expandable restraining member at least partially disposed within the longitudinal passageway of the introducer, the restraining member adapted to expand and compress the portal member to cause the portal member to assume the compressed condition thereof, to thereby facilitate passage of the portal member through the longitudinal passageway of the introducer and into the tissue tract.

Abstract
A surgical portal and introducer assembly includes an introducer and a portal member positionable within a longitudinal passageway of the introducer. The portal member is adapted for positioning within a tissue tract and has at least one longitudinal port for passage of a surgical object. The portal member comprises a compressible material and is adapted to transition between a first expanded condition and a second compressed condition. The assembly may include an expandable restraining member that may be disposed within the longitudinal passageway. The restraining member is adapted to expand and compress the portal member to cause the portal member to transition to the compressed condition.

13. A surgical portal and introducer assembly comprising:
-
an introducer having a longitudinal passageway and insertable through an opening in tissue, wherein the longitudinal passageway has a proximal region and a distal region, the proximal region having a first diameter and the distal region having a second diameter that is less than the first diameter; a portal positionable within the longitudinal passageway of the introducer, the portal having at least one longitudinal port for receiving a surgical object therethrough, the portal formed of a compressible material, and transitionable between an expanded condition and a compressed condition, the portal translatable through at least a portion of the longitudinal passageway when it is in the compressed condition, wherein the expanded condition of the portal is less than the diameter of the proximal region and greater than the diameter of the distal region; and an expandable restraining member at least partially disposed within the longitudinal passageway, the restraining member expandable to compress the portal thereby transitioning the portal to the compressed condition such that the portal is translatable through the longitudinal passageway. - View Dependent Claims (14, 15)
