Abstract

A surgical apparatus for permitting access to tissue includes an elongated introducer and a surgical port. The introducer includes an outer wall segment defining a longitudinal axis, a longitudinal port passage extending therethrough and a longitudinal slot in communication with the port passage. The introducer is dimensioned for at least partial introduction within an opening in tissue. The surgical port includes a port body mounted to the introducer with one of its leading and trailing ends disposed within the port passage and with the intermediate segment extending through the longitudinal slot and the other of the leading and trailing end external of the elongated introducer. The port body is dimensioned to be advanced within the port passage for deployment through the opening in the tissue and is adapted to transition from a compressed state to a released state.

Claims

1. A surgical apparatus for permitting access to tissue, which comprises:

an elongated introducer including a retractor segment and an outer wall segment defining a longitudinal axis and a longitudinal port passage extending therethrough, the outer wall segment having a longitudinal slot in communication with the port passage, the elongated introducer dimensioned for at least partial introduction within an opening in the tissue, the retractor segment disposed distal of the outer wall segment, the retractor segment extending radially outward from a distal end of the outer wall segment to retract the opening in the tissue; and

a surgical port including a port body having leading and trailing ends, an intermediate segment disposed between the leading and trailing ends, and at least one passageway for reception and passage of a surgical instrument, the port body movable along the entire elongated introducer with one of the leading or trailing ends disposed within the port passage and with the intermediate segment extending through the longitudinal slot, the other one of the leading or trailing ends external to the elongated introducer when the one of the leading or trailing ends is advanced along the entire port passage of the elongated introducer, the port body dimensioned to be advanced within the port passage for deployment through the opening in the tissue as generally directed by the elongated introducer, the port body comprising a compressible material adapted to transition from a compressed state when mounted to the elongated introducer to a released state when deployed from the elongated introducer.

2. The surgical apparatus according to claim 1 wherein the retractor segment defines an arcuate profile.

3. The surgical apparatus according to claim 1 wherein the outer wall segment of the elongated introducer is substantially arcuate along a major portion of the length thereof.

4. The surgical apparatus according to claim 1 wherein the retractor segment defines a general hook-shape and is arranged in oblique relation with the longitudinal axis.

5. The surgical apparatus according to claim 1 including a pusher member at least partially disposed within the longitudinal port passage of the elongated introducer, the pusher member adapted for longitudinal advancement to engage and deploy the port body from the introducer and through the opening in the tissue.

6. The surgical apparatus according to claim 1 wherein the elongated introducer includes a handle mounted to the outer wall segment, the handle dimensioned for engagement by a user.

7. The surgical apparatus according to claim 1 wherein the elongated introducer is substantially rigid.

8. The surgical apparatus according to claim 1 wherein at least a portion of the longitudinal slot is coated with a lubricious material.

9. The surgical apparatus according to claim 1 wherein a leading end of the elongated introducer is substantially open and a trailing end is closed.
