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 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.

Abstract: An infusion pump including an administration set configured to provide a fluidic pathway between a supply of infusate and an infusion set, at least one pressure sensor configured to sense a pressure of infusate within the administration set, and a control unit configured to monitor the sensed pressure, and apply a calculated tare adjustment to the monitored pressure to compensate for a decay of observable stress within the administration set as a result of stress relaxation.

Abstract: A catheter hub of a safety needle assembly that includes a multiuse valve uses a proximal portion of the catheter as an actuator to open the partition membrane of the valve when the valve is subjected to an external biasing force. In another embodiment, the actuator is formed as an integral component of the catheter hub.

Abstract: Infusion pumps and associated methods for delivering medicament to a user during error conditions. An infusion pump can include a sensor, a pumping mechanism to deliver medicament through an infusion set to the user, and a processor operably coupled to the sensor and the pumping mechanism. The processor can be configured to receive an indication from the sensor of an error condition, and continue operating the pumping mechanism to deliver a predetermined quantity of medicament without correcting the error condition. The predetermined quantity can be based at least in part on a characteristic of the infusion set.

Abstract: A safety catheter insertion 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 safety catheter insertion assembly including a catheter assembly having an elastomeric blood control valve and a catheter insertion device having a safety clip, the safety clip movable between an expanded configuration in which a portion of the safety clip applies a compressive force to a portion of the elastomeric blood control valve, and a collapsed configuration in which the compressive force is reduced and release of the safety clip from the elastomeric blood control valve is enabled.

Abstract: An LVP that provides peristaltic pumping to removably couplable administration set tubing assemblies supplying medical infusate. The LVP includes a housing, a drive-train assembly, and a controller. The housing includes an assembly receptacle configured to receive an administration set tubing assembly. The drive-train assembly provides mechanical peristaltic movement within the assembly receptacle. The drive-train assembly includes a stepper motor located within the housing and a camshaft assembly, driven by the stepper motor and at least partially extending into the assembly receptacle. The camshaft assembly includes a unitary camshaft and a plurality of tube engaging members that cooperatively move according to rotation of the unitary camshaft. Further, the controller is located within the housing that controls operation of the stepper motor and the camshaft assembly.
