Patent ID: 7329233

Claim:
An insufflation apparatus, which comprises: an elongated sleeve defining a longitudinal axis and having a proximal end and a distal end, the distal end defining a sharpened tip; a housing having a proximal end and a distal end, the distal end being connected to the proximal end of the elongated sleeve, the housing defining a port for receipt of insufflation gases; a stylet disposed within the elongated sleeve and defining a passageway to direct the insufflation gases from the port into a body cavity, the stylet being movable between an extended position wherein the distal end of the stylet extends beyond the sharpened tip of the elongated sleeve and a retracted position wherein the distal end of the stylet is proximal of the sharpened tip of the elongated sleeve; a biasing member engagable with the stylet so as to bias the stylet toward the extended position; and an indicator bulb mounted to the proximal end of the housing and extending therefrom, the indicator bulb having a generally transparent wall portion whereby the proximal end of the stylet is visible through the indicator bulb when the stylet is in the retracted position.
