Abstract

A medical apparatus is disclosed. The medical apparatus includes a trocar asembly having a cannula and a trocar, wherein (1) the cannula has (i) a lumen defined therein and (ii) a length L1, (2) the trocar is postionable between a first trocar position and a second trocar position, (3) the trocar is positioned within the lumen of the cannula when the trocar is positioned at the first trocar position, and (4) the trocar is completely removed from thelumen of the cannula when the trocar is posiitoned at the second trocar position. The medical apparatus also includes a sleeve having (i) a passageway extending therethrough, (ii) a sealing member extending therefrom, and (iii) a length L2, wherein (1) the cannula is positionable between a first cannula position and a second cannula position, (2) the cannula is positioned within the passageway of the sleeve when the cannula is positioned at the first cannula position, (3) the cannula is completely removed from the passageway of the sleeve when the cannula is positioned at the second cannula position, and (4) the length L1 of the cannula is greater than the length L2 of the sleeve such that a portion of the cannula extends out of the passageway of the sleeve when the cannula is positioned at the first cannula position. An associated medical procedure which utilizes the medical apparatus is also disclosed.
