Embodiment Construction

[0037]Various embodiments of the presently disclosed access assembly, or access port, and methods of using the same, will now be described in detail with reference to the drawings wherein like references numerals identify similar or identical elements. In the drawings, and in the following description, the term “proximal” refers to the end of the access port, or component thereof, that is closer to the clinician and the term “distal” refers to the end that is further from the clinician, as is traditional and conventional in the art. It should also be understood that the term “minimally invasive procedure” is intended to include surgical procedures through small openings / incisions performed within a confined space such as the thoracic cavity.

[0038]Referring now to FIGS. 1 and 2, an embodiment of the presently disclosed surgical access port, generally identified by the reference numeral 100, is depicted as a thoracic port 100 that is configured and dimensioned for insertion into the i...

Abstract

A method of accessing an internal portion of a patient including the steps of providing an access assembly including an outer frame, an inner member and a flexible member, inserting the inner member through an opening in tissue into a body of a patient with the flexible member extending proximally through the opening in tissue, moving at least a first portion or second portion of the outer member to a select unlocked spread position to enlarge the opening in tissue and the passageway through the flexible member, and subsequently moving the locking member to move the first and second engagement structures into a locking position to lock the first portion in the select spread position.
