Abstract
An obturator for a cannula includes an elongate member and a flexible disc. The cannula has proximal and distal ends and a lumen extending therebetween. The distal end of the cannula has a circular cross-section. The cannula also includes a first portion having a non-circular cross-section and at least one fluid aperture formed adjacent the distal end. The flexible disc of the obturator is coupled to a distal end of the elongate member, both of which are adapted to be telescopically received in the lumen of the cannula. The flexible disc is configured to restrict the flow of fluid, entering the at least one fluid aperture, through the lumen.
