Abstract: Embodiments disclosed herein are directed to connections systems including a port, a catheter, a cathlock and an adapter. The adapter can be coupled with a proximal end of the catheter and a cathlock can co-operate with the adapter to secure the catheter to the port in a fluid tight engagement. One of the cathlock or the adapter can threadably engage the port and employ mechanical advantage to radially compress the catheter and ensure a fluid-tight seal. The system can further include an insertion tool configured to facilitate securing the adapter to the catheter or securing the adapter or cathlock to the port. The adapter can be provided as a separate structure or coupled to the cathlock. Engagement of the adapter with the catheter can be signaled with an audible click. Optionally the adapter can include a skirt configured to compress the catheter onto the adapter stem.

Abstract: Medical devices and methods thereof for determining bacterial infections in blood. The medical devices and methods thereof can utilize a coating including an antibody conjugated to a reporter protein configured to indicate a bacterial infection in a patient's blood by way of an antigen thereof. Exemplary medical devices include, but are not limited to, a catheter assembly, an AV fistula needle set, an extension set for either a catheter assembly or an AV fistula needle set, and a hemodialysis tubing set. The medical devices and methods thereof can utilize immunochromatographic separation of the antibody and an antigen-antibody complex to indicate a bacterial infection in a patient's blood.

Abstract: Disclosed herein are vascular access systems and methods thereof. For example, a vascular access system includes a port configured for subdermal implantation and a single-use access device. The port can include a port hub and a catheter tube. The port hub can include an access funnel and a septum defining a pair of port-hub lumens. The catheter tube can include a septum defining a pair of catheter-tube lumens fluidly coupled to the pair of port-hub lumens. The access device can include a bifurcated hub and a pair of cannulas. The pair of cannulas defines a pair of cannula lumens coupled to a pair of access device-hub lumens of the bifurcated hub. The pair of cannulas can be configured to simultaneously insert into the access funnel and couple the pair of cannula lumens to the pair of catheter-tube lumens when the pair of cannulas is fully seated in the port hub.

Abstract: A catheter (100) for treating hypervolemia in a patient includes a luminal ingress (112) joined to a luminal egress (114) at a distal end portion (116) of the catheter having a closed distal end (102). The distal end portion is configured to at least temporarily reside within a vessel of the patient, the distal end portion including a semipermeable membrane. The luminal ingress is designed to convey an influent having a first osmotic concentration to the distal end portion. The semipermeable membrane is configured to pass blood-borne water from the vessel into the distal portion. The blood-borne water is absorbed by the influent to produce an effluent having a second osmotic concentration lower than the first osmotic concentration. Systems (200) with the catheter and methods for treating hypervolemia are also disclosed.
