Abstract

An integrated vascular delivery system having a frame configured to receive a catheter insertable in a patient to deliver fluid at an insertion site. The frame includes a first hub, a second hub, and a pair of flexible lateral members extending between the hubs and including a tubular lateral member. The system also includes a fluidic channel that fluidically communicates with the catheter, wherein the fluidic channel passes through the tubular lateral member and at least one of the hubs, and includes a fixed turnabout portion in which fluid flows in a direction different from that within the catheter. The first and second hubs provide anchoring points on the patient distributed around the insertion site and on opposite ends of the catheter, thereby anchoring the frame to the patient and stabilizing the catheter. A method is provided for using an integrated vascular delivery system.

Claims

1. An integrated vascular delivery system comprising:

a first hub having a proximal region, the first hub comprising;

a catheter configured for insertion into a patient extending from the proximal region; and

at least one fluidic channel configured to communicate with the catheter within the first hub and extending from the proximal region of the first hub;

a second hub spaced apart from the first hub and configured to stabilize the system; and

a first and a second lateral member extending between the first hub and the second hub, wherein the at least one fluidic channel passes through at least one of the first and second lateral members.

2. The system of claim 1, wherein the lateral member including the fluidic channel extends from a central portion of the first hub to a spaced apart portion of the proximal region.

3. The system of claim 1, wherein the at least one fluidic channel passes through the first hub at an angle such that the at least one fluidic channel extends from a center of the first hub to an outer peripheral portion of the proximal region of the first hub.

4. The system of claim 1, wherein the at least one fluidic channel includes a fixed turnabout portion in which a direction of fluid flow through the at least one fluidic channel is angularly displaced by approximately 180 degrees.

5. The system of claim 1, wherein the first and second lateral members are bendable and configured to allow one of the first and second hubs to fold over the other of the first and second hubs.

6. The system of claim 1, wherein at least one of the first and second lateral members extends through the second hub.

7. The system of claim 1, wherein the first and second lateral members extend through the second hub.

8. The system of claim 1, wherein the at least one fluidic channel comprises a first fluidic channel and a second fluidic channel.

9. The system of claim 8, further comprising a first extension tube defining a first flow path and a second extension tube defining a second flow path, the first extension tube fluidically coupled to the first fluidic channel and the second extension tube fluidically coupled to the second fluidic channel.

10. The system of claim 9, wherein the first extension tube is integrally formed with the first fluidic channel and extends through the second hub and the second extension tube is integrally formed with the second fluidic channel and extends through the second hub.

11. The system of claim 1, further comprising a septum coupled to the first hub, the septum being configured to receive a needle.

12. The system of claim 1, wherein the first hub is configured to be positioned on a first side of an insertion point and the second hub is configured to be positioned on a second side of the insertion point.

13. A method of using an integrated vascular delivery system, the method comprising:

supplying an integrated vascular delivery system, wherein the system comprises a first hub having a proximal region, a catheter extending from the proximal region, a second hub, a first and a second lateral member extending between the first hub and the second hub, and at least one fluidic channel that fluidically communicates with the catheter within the first hub, extends from the proximal region of the first hub, and passes through at least one of the first and second lateral members, wherein the system is configured to allow one of the first hub and the second hub to fold over the other of the first and second hubs, thereby exposing a proximal end of the catheter;

inserting the catheter into a patient at an insertion site;

unfolding the system; and

securing the system to the patient at a plurality of anchoring points around the insertion site, thereby stabilizing the system relative to the insertion site.

14. The method of claim 13, further comprising allowing fluid to flow between the catheter and the patient.

15. The method of claim 13, further comprising decoupling at least one of the first hub and the second hub from a needle housing.

16. The method of claim 13, wherein the system further comprises a needle extending through the first hub and the catheter, the method further comprising the step of removing the needle from the first hub and the catheter.

17. The method of claim 13, wherein securing the system comprises securing the first hub at a first anchoring point distal to the insertion site and securing the second hub at a second anchoring point proximal to the insertion site.
