Abstract: A blood sequestration device configured to isolate an initial, potentially contaminated portion of blood from the flow of blood of a patient, prior to directing the flow of blood to an outlet port where the blood can be accessed. The blood sequestration device including a body member having an interior wall defining a fluid conduit having a distal portion, a first proximal portion, and a second proximal portion, wherein the first proximal portion defines a sequestration chamber configured to isolate an initial portion of blood of a flow of blood, a vent path configured to enable the escape of gas initially trapped within the sequestration chamber.

Abstract: A system for occlusion detection, including a cartridge containing an infusate, a plunger driven by a drive mechanism configured to be advanced within the cartridge to expel infusate from the cartridge, a force sensor configured to sense an actual force exerted by the plunger, and a control unit configured to determine an estimated force based on an expected decay in frictional force between the plunger and the cartridge for comparison to the actual force sensed by the force sensor, wherein a deviation between the estimated force and the actual force exceeding a threshold triggers an occlusion alarm.

Abstract: A passive safety catheter assembly configured to inhibit access to the distal tip of a needle cannula prior to release of a catheter insertion assembly from a catheter hub. The passive safety catheter assembly includes a safety clip assembly configured to transition between a first position in which the safety clip assembly selectively couples the catheter insertion assembly to the catheter hub, and a second position in which the safety clip assembly traps the sharp distal tip of the needle cannula within the safety clip assembly prior to release of the coupling between the catheter insertion assembly and the catheter hub.

Abstract: An assembly is configured to position a peristaltic tube with respect to a linear peristaltic pump drive of an infusion pump. The assembly can include a peristaltic tube, first and second tube couplers, a frame, first and second securement plates, a free-flow prevention arm, and a biasing mechanism. The frame can include a snap-fit tab configured to releasably secure the assembly to an assembly receptacle of the infusion pump. The free-flow prevention arm can be selectively movable between a free-flow preventing position and a free-flow allowing position. A latching mechanism can be ergonomically manipulable to latch the free-flow prevention arm in a free-flow allowing position, and to unlatch the free-flow prevention arm such that the biasing mechanism is able to bias the free-flow prevention arm to the free-flow preventing position.

Abstract: A catheter assembly includes a catheter hub defining an interior cavity and a catheter tube extending distally thereof. A rigid actuator is positioned to extend proximally in the interior cavity and support a seal member positioned thereon in the interior cavity. The seal member includes a central membrane, a distal portion, and a proximal portion. An hourglass shaped actuator cavity is formed in the distal portion and receives a barbed end of the actuator. The outer surface of the seal member is in partial circumferential engagement with the catheter hub to define an air path that allows fluid communication between areas of the interior cavity distal and proximal of the seal member. The seal member may be configured for multi-use and include a biasing member that moves the seal member to force the membrane back over the actuator to close the membrane.

Abstract: An access device for placing a medical article within a body space includes a syringe, a needle, and a sheath which are employed together with a guide wire. The sheath can be coaxially and slideably disposed about the needle. During insertion of the sheath over the needle, guide wire and into the body space, the syringe provides a negative pressure to ensure that any air located between the inside diameter of the sheath and the outside diameter of the needle is drawn into the needle rather than into the body space. In certain embodiments, a dilator is coaxially and slideably disposed about the needle and within the sheath.

Abstract: A method of making a flexible medical article or tube, for example, a sheath for a vascular access device, is provided. The method can include extruding a polymer, for example, a polycarbonate-urethane copolymer, to form a tube and annealing the extruded polymer. The method can further include cutting the extruded tube to a desired length before or after annealing, flaring one end of the annealed tube and over-molding the flared portion onto a hub, and forming the other end of the tube into a tip. A sheath formed by such a method is also provided.

Abstract: A port is adapted to be implanted to a body with its top exposed to the environment. The port has a housing defining a chamber that has an opening at the top of the housing. An aperture having a lumen attached thereto is formed at the lower portion of the chamber. For infusion, an insert that has an internal passageway that connects a fluid inlet at its top surface and a bore at its sidewall is sealingly mated to the chamber. The bore sealingly aligns with the aperture. After infusion, the insert is removed, and a blank insert is fitted to the chamber. A band of tissue ingrowth media encircles the housing to form an aseptic barrier where the outer wall of the housing and the tissue of the body encircling the housing meet.
