Claim:
1. A blind trocar sleeve for preventing transient jet streaming conditions during insufflating a body cavity comprising: a housing; an inlet port attached to said housing; a one-piece elongated tubular member directly attached to said housing, said elongated tubular member comprising a sidewall forming a centrally located cylindrical plenum chamber therein and a closed end to prevent insertion of an instrument therethrough with the cylindrical plenum chamber free of obstruction, said elongated tubular member having a plurality of insufflating fluid delivering apertures therein, said plurality of insufflating fluid delivering apertures positioned circumferential to said cylindrical plenum chamber and in fluid communication with said cylindrical plenum chamber for delivery of the insufflating fluid from the chamber to a body cavity at a velocity below a jet streaming velocity with the plurality of insufflating fluid delivering apertures sufficiently small to preclude insertion of surgical instruments therethrough.
