Abstract

An integrated vascular delivery system and method of use, the system including: a frame having a catheter hub that provides a first anchoring point on the patient and receives a catheter insertable in the patient to transfer fluid at an insertion site, a stabilization hub that provides a second anchoring point on the patient, at least one lateral member extending between the catheter and stabilization hubs, and a fluidic channel. The frame operates in a folded configuration in which the hubs are coupleable and an unfolded configuration in which the anchoring points are distributed around the insertion site to anchor the frame to the patient, thereby stabilizing the catheter. In some embodiments, the system further includes a septum that helps prevent fluid leakage from the catheter hub, or a needle shield that covers the distal end of a needle used during catheter insertion.

Claims

1-20. -20. (canceled)

21. An integrated vascular delivery system adapted to facilitate insertion of a catheter into a patient at an insertion site, comprising:

a frame including;

a catheter hub configured to couple to the catheter,

a stabilization hub,

a sensor configured to couple to the catheter hub and/or the stabilization hub,

a first flexible lateral member defining a lumen and extending from a distal region of the catheter hub to a proximal region of the stabilization hub,

a fluidic channel configured to pass through the catheter hub, wherein the fluidic channel comprises a fixed turnabout portion defined within the catheter hub, and

a septum coupled to the catheter hub, wherein the septum is configured to receive a needle to facilitate insertion of the catheter at the insertion site; and

a needle shield configured to capture at least a portion of the needle as the needle is withdrawn from the catheter hub.

22. The system of claim 21, wherein the needle shield is coupled to the distal region of the catheter hub.

23. The system of claim 21, further comprising a second flexible lateral member.

24. The system of claim 23, wherein the frame operates in a folded configuration by way of the flexible lateral members.

25. The system of claim 24, wherein in the folded configuration of the frame, the catheter hub is configured to reversibly couple to the stabilization hub, and wherein the frame further operates in an unfolded configuration wherein first and second anchoring points are distributed about the insertion site to anchor the frame to the patient, thereby stabilizing the catheter.

26. The system of claim 24, wherein one of the catheter hub and stabilization hub includes an extension, wherein in the folded configuration of the frame, the extension is received by the other one of the catheter hub and the stabilization hub.

27. The system of claim 24, wherein the stabilization hub includes an extension with a through hole configured to receive the needle, and the catheter hub includes a recess configured to receive the extension, such that the frame is locked in the folded configuration when the needle passes through the septum and into the through hole of the extension.

28. The system of claim 21, wherein the sensor is configured to measure at least one parameter of the patient.

29. The system of claim 28, wherein the at least one parameter comprises temperature, blood pressure, pulse rate, pH, and/or flow rate.

30. The system of claim 21, wherein the stabilization hub is retained in an angularly displaced position relative to the catheter hub.

31. The system of claim 21, wherein the fluidic channel is configured to direct fluid flow into the fixed turnabout portion.

32. The system of claim 21, wherein the catheter hub provides a first anchoring point on the patient.

33. The system of claim 32, wherein the stabilization hub provides a second anchoring point on the patient.

34. The system of claim 21, wherein the needle shield allows the needle to penetrate the catheter, through the needle shield, in an inactive configuration, and that covers a distal end of the needle in an active configuration, in withdrawing of the needle from the catheter.

35. The system of claim 34, wherein the needle shield is removably coupled to the catheter hub, and configured to engage a needle catch, upon withdrawal of the needle from the catheter hub, that transitions the needle shield from the inactive configuration to the active configuration.

36. The system of claim 21, wherein the fluidic channel is disposed within the first flexible lateral member, and wherein the frame further comprises a solid lateral opposite the first flexible lateral member in relation to the catheter hub, that couples the catheter hub to the stabilization hub.

37. The system of claim 21, wherein the needle shield includes a spring clip.

38. The system of claim 37, wherein at least a portion of the spring clip is positioned proximal of the catheter hub, and wherein the spring clip is configured to capture at least a tip of the needle.

39. The system of claim 37, wherein the spring clip is configured to be coupled to an outer region of the catheter hub.

40. The system of claim 37, wherein the catheter hub further comprises a receiving feature, and wherein the spring clip is configured to be coupled to the receiving feature.

41. The system of claim 21, wherein the septum is configured to direct the needle into a portion of the fixed turnabout portion and into the catheter.
