Abstract

A method for performing a surgical procedure includes the steps of: accessing a surgical site with an access member, the access member having proximal and distal ends, and defining a longitudinal axis, the access member having an elongated element operatively connected thereto; transitioning the access member from a first condition having a first dimension orthogonal to the longitudinal axis to a second condition having a second dimension orthogonal to the longitudinal axis greater than the first dimension by drawing the elongated element in a proximal direction; anchoring the access member within a tissue passage leading to the surgical site when in the second condition thereof; and introducing a surgical object through a longitudinal opening of the access member to perform a surgical task.

Claims

1. A method for performing a surgical procedure, comprising the steps of:

providing a surgical access apparatus comprising;

a housing having proximal and distal ends and being configured to removably receive at least one surgical instrument;

a tubular member extending distally from the housing, the tubular member being adapted to removably receive the at least one surgical instrument and repositionable between a first position, in which the tubular member is configured for at least partial insertion into an opening in the tissue, and a second position, in which the tubular member is configured to facilitate anchoring of the tubular member within the tissue;

a connective member secured to the tubular member;

at least one filament secured to the connective member and extending proximally therefrom; and

at least one manual member secured to the at least one filament, the at least one manual member being configured and dimensioned for grasping by a clinician such that the at least one filament is movable in a proximal direction to facilitate selective repositioning of the tubular member from the first position to the second position;

advancing the tubular member distally into an opening in the tissue while in the first position; and

moving the at least one manual member in a proximal direction to cause corresponding movement of the connective member to thereby reposition the tubular member from the first position to the second position to anchor the surgical access apparatus within the tissue.

2. The method of claim 1, wherein the housing includes locking structure and including the step of engaging the locking structure with one or more of the at least one filament and the at least one manual member to maintain the tubular member in the second position.

3. The method of claim 1, wherein the step of repositioning the tubular member from the first position to the second position causes a portion of the tubular member to lie in a plane substantially parallel to the tissue.

4. The method of claim 1, wherein the tubular member includes a mesh of braided fibers and, wherein during the step of moving the at least one manual member, the mesh is adapted for radial expansion to facilitate passage of the surgical instrument into the lumen of the tubular member.

5. The method of claim 1, further including the step of introducing a surgical instrument through the surgical access apparatus.

6. The method of claim 5, including the step of establishing a substantially fluid-tight seal about the surgical instrument with the connective member.

7. The method of claim 5, wherein the mesh of braided fibers includes a substantially elastic material such that during the step of introducing the surgical instrument through the surgical access apparatus, the axial length of the tubular member changes.

8. The method of claim 5 wherein the mesh of braided fibers include a substantially inelastic material such that during the step of introducing the surgical instrument through the surgical access apparatus, the axial length of the tubular member remains substantially constant.
