Abstract: Methods and apparatus to reduce deadspace in syringes and other devices with the use of volume displacing members that occupy space within one or more interior spaces of such devices. The volume displacing members are also equipped with one or more internal flow passages that facilitate a flow of a fluid through it. The volume displacing members are also adapted to cooperate with features of the devices that house them to form air-tight and liquid-tight seals that at least partially determine a fluid pathway through the devices.

Abstract: A needle guard assembly having a resilient arm extending from a base situated to slide along the shaft of a needle. In one implementation the needle guard has an elongate containment member that rides with the resilient arm and is co-operable with the resilient arm to effectuate a covering of the entire distal tip of the needle upon the needle being retracted into the needle guard.

Abstract: Luer activated valves are disclosed herein that are capable of being integrated into different types of medical devices, such as, IV catheters, sheath introducers, tear-away sheaths, etc. for the purpose of regulating the passage of fluids and/or devices into and out of such devices.

Abstract: A needle that includes an elongate tube having a proximal end, a distal end, an outer wall and an inner wall that defines a through passage, the through passage having a longitudinal central axis. The distal end of the tube includes a bevel having a length and that terminates at a distal tip. The inner wall of the tube has an exposed area in the bevel that is viewable from the top side of the tube. A spiral channel is formed in the inner wall of the tube along at least a portion of the length of the exposed area, the spiral channel having a proximal facing surface configured to reflect ultrasonic waves directed at it.
