Abstract

A laparoscopic introducer and method of use comprise a laparoscopic channel and a guide channel for a secondary instrument. Upon initial insertion of the introducer, the guide channel closely conforms to the body of the introducer so as to only negligibly increase the cross-sectional profile thereof. Following insertion, the guide channel can be distended by means of a dilator. Thus, the guide channel allows a secondary instrument to be inserted into the body to perform laparoscopic procedures wherein the instrument is inserted and utilized along the same longitudinal axis as the laparoscope. Thus, the number of laparoscopic ports are reduced and visual distortions associated with triangulation are avoided. The guide channel is constructed from an extremely thin, but very strong and noncompliant membrane which may also be reinforced by means of a force distribution mechanism. The guide channel may also be provided with guide rails or other tracking mechanisms to ensure accurate and secure advancement of the dilator or secondary instrument. The method of construction of the introducer and an apparatus and method for dilation are also disclosed.
