Abstract: A trocar insertion device to facilitate the introduction of a conventional trocar into a patient, the insertion device including a generally elongate insertion arm that has a tubular configuration structured and disposed to removably receive a trocar mounted thereon, and a generally narrow and short guide segment extending from a forward end of the insertion arm. The guide segment includes a pointed tip structured and disposed to facilitate penetration of the guide segment through a patient's skin so as to define a small guide port in the patient's skin.

Abstract: An improved trocar assembly including an elongate shaft, with an open proximal end, an open distal end, an axial channel, and a substantially smooth exterior surface so as to prevent frictional engagement of the exterior surface with various tissue plains at an incision opening in the patient, and a distal expandable component, disposed substantially at the distal end of the elongate shaft and having at least one inflatable cuff structured to selectively maintain the elongate shaft partially within the patient subsequent to its insertion into the patient.

Abstract: An endotracheal tube cleaning device to be used in an endotracheal tube of the type that has a flow through passage with an interior wall surface that defines an interior diameter thereof. The endotracheal tube cleaning device includes an elongate tubular member with a length at least as long as the endotracheal tube and a diameter smaller than a corresponding diameter of the endotracheal tube. Defined within the elongate tubular member, and extending from generally a first end to a second end thereof, is a channel. The channel terminates in an outlet port connected in fluid flow communication with a resilient material bladder that is structure to inflate to a diameter sufficient to engage the interior wall surface of the endotracheal tube.
