Abstract: A thoracic catheter is provided with a distal end and a proximal end. The catheter is formed by a tube of flexible material having at least one radial opening at the distal end for draining a body cavity. The proximal end of the tube has a stiffened and sharpened portion whereby pressure applied to the stiffened proximal end from inside the body cavity leads the catheter outwardly through body tissue whereupon the sharpened stiffened proximal end can be severed and the catheter left in situ. The stiffened end is a rigid rod that extends outward of the proximal end of the tube and terminates in the tube short of a cut-off point whereby the tube is severed and the rod and severed proximal end portion is disposed of. The rigid rod may extend a substantial distance inside the tube and be shapable into a grippable shape to assist the user in maneuvering the rod and tube into and through a desired path in the surgical site.

Abstract: Conventional endotracheal tubes are provided with improved proximal end connector units by which the endo tubes may be attached to breathing equipment or like fluid flow devices in a manner that mitigates interference with operations being performed on patients intubated with the endo tubes, such units comprising a straight, rigid, cylindrical distal end portion, a straight, rigid, cylindrical proximal end portion, a central tubular portion joining the distal end portion to the proximal end portion, the central tubular portion being bendable in an arc of at least 180.degree.
