Abstract: Introducer sheaths are described. In one embodiment, an introducer sheath comprises a sheath hub, a fixed housing coupled to the sheath hub, a rotating element rotatably coupled to the fixed housing, a sheath tube fixedly coupled to the rotating element, and a lock coupled to the rotating element. The lock is capable of preventing the rotating element and the sheath tube from rotating with respect to the sheath hub.

Abstract: A laminar valve flow module is disclosed and may include a proximal chamber, a purge chamber, and a sheath chamber in fluid communication with each other and between an inlet opening and an exit opening. A guide chamber may be located within the proximal chamber and in fluid communication with the inlet opening, the proximal chamber, and the sheath chamber. The sheath chamber is in fluid communication with the exit opening.

Abstract: A multifunction hand tool includes a tubular body having first and second open ends, a front wall, a rear wall, and first and second side walls. A first screwdriver tip protrudes from the rear wall in a longitudinal direction so as to be coplanar with the rear wall. A second screwdriver tip protrudes from the front wall in a lateral direction so as to be perpendicular with the front wall. A socket opening is formed in the front wall for engaging a hexagon-shaped fitting. First and second slots are formed in the first and second side walls, respectively, for engaging a flat handle of a ball valve. A third slot is formed in the rear face for engaging a flat handle of a ball valve. A cutout portion in the tubular body is defined by a removed section of the front wall and the first and second side walls.
