A bolus delivery device is provided that comprises a housing and a reservoir defined by an activation dome and a reservoir seat and disposed within the housing for receipt of a volume of a fluid. The bolus delivery device further comprises a bladder disposed in the housing that is in fluid communication with the reservoir for receipt of the fluid from the reservoir; an actuator; an inlet conduit in fluid communication with the reservoir for providing the fluid to the reservoir; and an outlet conduit in fluid communication with the bladder for providing the fluid to a patient. The actuator is in operative communication with the reservoir to initiate a flow of the fluid from the reservoir to the bladder. The bladder expands as the bladder receives the fluid and contracts as the bladder dispenses the fluid. An infusion assembly including a bolus delivery device also is provided.

Systems and methods are provided for signaling a condition of an infusion assembly. An example system may comprise an elastomeric pump that includes a chamber for receipt of a volume of fluid, an outer layer configured to expand and contract as the chamber receives and dispenses the fluid, and a passive indicator provided on the outer layer for signaling a change in the volume of the fluid in the chamber. The example system further may comprise an image capture device configured to capture an image of the pump, and a processing system configured to process the image to signal the condition of the infusion assembly to a user of the system. An example method may comprise capturing the image of the pump; processing the image; and displaying information to the user of the pump to communicate a condition of the pump to the user. Various elastomeric pumps for infusion assemblies also are provided.

The present disclosure is directed to an ultrasonic catheter assembly. More specifically, the catheter assembly includes a catheter and one or more piezoelectric or echogenic components. The catheter has a side wall that extends from a proximal end and a distal end that defines a lumen extending from the proximal end to the distal end. Thus, the lumen is configured to deliver a treatment fluid from the proximal end to the distal end. In addition, the piezoelectric component(s) are configured with the side wall of the catheter and/or embedded at least partially within the side wall of the catheter. As such, the piezoelectric component(s) are configured to enhance ultrasonic imaging of the catheter, e.g. when activated by a stimulator assembly.

Indicators for indicating the integrity of a seal of a sterilization container are provided. For example, a seal indicator may indicate whether the container is sufficiently sealed to prevent an ingress of contaminants into the container. If the container is sufficiently sealed, the seal indicator is in one state and displays a first indicium, and if the sterilization container is not sufficiently sealed, the seal indicator is in another state and displays a second indicium. Thus, the seal indicator undergoes a visible change in state when the sterilization container transitions from unsealed to sealed, such that the user may be assured that the container is properly sealed to maintain sterility of the articles post-sterilization. Further, the seal indicator undergoes a visible change in state if the seal is subsequently broken, to signal to the user that the seal and the sterility of the container interior has been compromised.

A needle assembly for use with an ultrasound imaging system includes a needle having a proximal end and a distal end. The distal end is adapted to be inserted into a patient. The needle assembly also includes a transducer mounted to an exterior surface of the needle at the distal end. Further, the needle assembly includes a flexible printed circuit board mounted on the exterior surface of the needle from the proximal end to the distal end. As such, the flexible printed circuit board electrically connects the transducer to a power source.

The present invention is directed to an echogenic catheter assembly. The catheter assembly includes a catheter having a proximal end and a distal end that defines a lumen extending from the proximal end to the distal end. Further, the catheter assembly includes a coil member configured with at least a portion of the lumen of the catheter. The coil member forms a plurality of outwardly extending projections. One or more of the outwardly extending projections define a cross-sectional shape having at least one non-arcuate edge. As such, the non-arcuate edges of the outwardly extending projections are configured to enhance ultrasonic imaging of the catheter when inserted into a patient.

Echogenic coil member for a catheter assembly

The present invention is directed to an echogenic member assembly for use with a catheter assembly. The echogenic member assembly includes at least one echogenic member having a cylindrical body extending between a first end and a second end. Thus, the body defines a longitudinal length between the first and second ends. Further, the cylindrical body has an exterior surface extending from the first end to the second end. The exterior surface includes a plurality of discontinuities arranged in a predetermined pattern so as to enhance ultrasonic imaging. In addition, the longitudinal length of the echogenic member is less than a total length of a catheter of the catheter assembly. As such, the echogenic member provides enhanced ultrasonic imaging to the catheter assembly without compromising the inherent flexibility of the catheter.

The present invention is directed to an echogenic coil member for a catheter assembly and methods of manufacturing same. The catheter assembly includes a catheter having a proximal end and a distal end that defines a lumen extending from the proximal end to the distal end. Thus, the echogenic coil member is configured within the lumen of the catheter. Further, the coil member includes a plurality of outwardly extending projections that contain a plurality of discontinuities. As such, the discontinuities are configured to enhance ultrasonic imaging of the catheter assembly.
