Publication number: 20240269375Abstract: 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.Type: ApplicationFiled: February 22, 2024Publication date: August 15, 2024Inventors: Hector Dung Truong, Justin J. Coker, Paul D. Jun

Patent number: 11602593Abstract: An elastomeric pump having at least one sensor for sensing changes in elongation of a bladder of the pump is provided. Also provided is an infusion assembly including an elastomeric pump having a bladder, at least one sensor for sensing changes in elongation of the bladder, and an indicator for providing one or more outputs of the sensor. The sensor may be a flexible sensor positioned in contact with the bladder of the pump, or a dielectric material may be incorporated into the material the bladder is made from such that the dielectric elastomer material of the bladder forms the sensor.Type: GrantFiled: December 15, 2016Date of Patent: March 14, 2023Assignee: Avent, Inc.Inventors: Kenneth C. Hsu, Steve S. Khalaj, Paul D. Jun, John A. Rotella, James Lee Shippy, III

Patent number: 11141565Abstract: 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.Type: GrantFiled: June 23, 2016Date of Patent: October 12, 2021Assignee: Avent, Inc.Inventors: Justin Coker, Steve S. Khalaj, Paul D. Jun
