Abstract: The present disclosure relates to a hemostasis valve with a selectively coupled torque device. The hemostasis valve may include a first mating interface, and the torque device may comprise a second mating interface. The first interface may comprise a groove that retains the second interface, which may comprise a ridge. An axial force may couple and decouple the interfaces. The interfaces may be configured to allow the torque device to rotate relative to the hemostasis valve when in a coupled position.

Abstract: An obturator device for protecting a needle bevel and facilitating insertion of a needle into an elongate medical tube, such as a drainage catheter, is disclosed. The obturator device includes a jacket that mates and is substantially flush with the needle bevel, and a sleeve that encircles the jacket and needle bevel to protect against piercing or puncturing the medical tube during a medical procedure. The obturator device also includes a mandrel coupled to the jacket and extending outwardly therefrom and into a needle lumen to secure the jacket against the needle. In an example use, the obturator device and needle are advanced through a cavity of the medical tube until the obturator device extends from a distal end of the medical tube. Thereafter, the obturator device is removed to expose the needle bevel on a distal end of the medical tube for insertion into a patient's body.

Abstract: The present invention relates to a primer bulb for use with a contrast media delivery system. The contrast media delivery system is configured to facilitate the intravenous delivery of contrast media from a contrast media reservoir to a patient. The primer bulb is configured to facilitate the flow of contrast media from the contrast media reservoir. The primer bulb is compressed by the user to create a head of pressure above the contrast media in the contrast media reservoir. The head of pressure overcomes the surface tension of the contrast media while drawing contrast media into the length of tubing positioned between the primer bulb and the contrast media reservoir.
