Description

TECHNICAL FIELD

[0001] The present application relates to the medical field, and in particular to multi-lumen vascular access devices and related methods. BACKGROUND

[0002] Vascular access devices, such as catheters, are commonly used to infuse fluids into a patient's vasculature. For example, vascular access devices can be used to infuse normal saline solutions, various medicaments, and total parenteral nutrition solutions. Vascular access devices can also be used to withdraw blood from a patient. However, before withdrawing blood from a patient and taking a blood sample, the infusion of normal saline solutions, various medicaments, and total parenteral nutrition solutions should be stopped. Thus, there can be a delay in delivering the required fluids to the patient, or the clinician can access the patient's vasculature through an additional needle stick, which can cause injury to the patient.

[0003] Repeated access to the vascular access device to withdraw blood can increase the risk of introducing microorganisms into the vascular access device and infection. Repeated access to the vascular access device to withdraw blood can also increase the risk of thrombus and occlusion in the vascular access device lumen from not thoroughly and properly flushing the vascular access device with blood flowing through the vascular access device.

[0004] The subject matter claimed herein is not limited to implementations that solve all or only some of the disadvantages or problems described above.

[0043] Now refer to Figures 1A-1C The diagram illustrates a vascular access device 10 according to some embodiments. In some embodiments, the vascular access device 10 may include a first lumen 12, which may include a distal end 14 and a proximal end 16. In some embodiments, the vascular access device 10 may include a second lumen 18, which may include a distal end 20 and a proximal end 22. In some embodiments, the distal end 20 of the second lumen 18 may be proximal to the distal end 14 of the first lumen 12. In some embodiments, when the catheter 40 is a midline catheter rather than a peripherally inserted central catheter, the termination position of the second lumen 18 may be closer to the distal end 14 of the first lumen 12.

[0044] In some embodiments, the vascular access device 10 may include an opening 24 or a valve, which may be adjacent to the distal end 20 of the second lumen 18. In some embodiments, the vascular access device 10 may include a plurality of openings 24 or a plurality of valves, which may be disposed along the second lumen 18.

[0045] In some embodiments, the vascular access device 10 may include a first connector 26 disposed at the proximal end 16 of the first lumen 12. In some embodiments, the vascular access device 10 may include a second connector 28 disposed at the proximal end 22 of the second lumen 18. In some embodiments, the first connector 26 and / or the second connector 28 may include a male Luer connector or a female Luer connector. In some embodiments, a needleless access connector (not shown) may be coupled to the first connector 26 and / or the second connector 28. In some embodiments, the first connector 26 may include a different color and / or marking than the second connector 28, which may help clinicians distinguish between the first lumen 12 and the second lumen 18. In some embodiments, the first extension tube 36 may include a different color and / or marking than the second extension tube 38, which may help clinicians distinguish between the first lumen 12 and the second lumen 18. In some embodiments, the needleless access connector may include an anti-backflow or positive displacement connector.

[0046] In some embodiments, the vascular access device 10 can include a catheter hub 30, which can include a distal end 32 and a proximal end 34. In some embodiments, the vascular access device 10 can include a partition 35, which can extend between the distal end 32 of the catheter hub 30 and the proximal end 34 of the catheter hub 30. In some embodiments, the partition 35 can separate the first lumen 12 and the second lumen 18 within the catheter hub 30. In some embodiments, the first lumen 12 and the second lumen 18 can be arranged side-by-side, for example as shown in Figure 1C .

[0047] In some embodiments, the vascular access device 10 can include a first extension tube 36, which can extend from the proximal end 34 of the catheter hub 30 to the first connector 26. In some embodiments, the vascular access device 10 can include a second extension tube 38, which can extend from the proximal end 34 of the catheter hub 30 to the second connector 28. In some embodiments, the vascular access device 10 can include a catheter 40 extending from the proximal end 34 of the catheter hub 30. In some embodiments, the catheter 40 can include a peripheral intravenous catheter, a peripheral inserted central catheter, or a midline catheter. In some embodiments, a distal end 42 of the catheter 40 can include a distal opening 44 and / or one or more valves or one or more side holes 46. In some embodiments, a proximal end of the catheter 40 can be secured within the catheter hub 30.

[0048] In some embodiments, the entire length of the catheter 40 and the first extension tube 36 can include the first lumen 12. In some embodiments, a proximal portion 48 of the catheter 40 and the second extension tube 38 can include the second lumen 18. In some embodiments, the catheter 40 can include a portion of the partition 35 that can extend through the proximal portion 48 of the catheter 40. In some embodiments, the first lumen 12 and the second lumen 18 can be arranged side-by-side within the catheter hub 30 and the proximal portion 48. In some embodiments, the first extension tube 36 can include a clamp that can prevent blood flow through the first lumen 12 in response to the clamp being in a closed position. In some embodiments, the second extension tube 38 can include a clamp that can prevent blood flow through the second lumen 18 in response to the clamp being in a closed position. In some embodiments, the clamp on the first extension tube 36 can include a different color and / or marking than the second extension tube 38 and / or the clamp on the second extension tube 38, which can assist a clinician in distinguishing between the first lumen 12 and the second lumen 18.

[0049] In some embodiments, the vascular access device 10 can include a blood collection device 50 that can be coupled to the second connector 28 and / or in fluid communication with the second lumen 18. In some embodiments, the blood collection device 50 can be directly coupled to the second connector 28. In some embodiments, the blood collection device 50 can be coupled to the second connector 28 through a needleless connector. In some embodiments, the blood collection device 50 can include a means 54 that extends through the second lumen 18 and out of the opening 24 or valve. In some embodiments, the means 54 can include a tube, a guidewire, a wire, an obturator, a probe, a sensor, or any other suitable means. In some embodiments, multiple openings 24 or multiple valves can be adjacent to the distal end 20 of the second lumen 18.

[0050] In some embodiments, the blood collection device 50 can include or correspond to a blood collection container. In some embodiments, the blood collection container can include a syringe, a vacuumed blood collection tube, a microsample collection device, or any other container. In some embodiments, the blood collection device 50 can include a or LUER-LOK TM that can be configured to receive a blood collection container. In some embodiments, the blood collection device 50 can include a needle 52 that can be configured to be inserted into the blood collection container. In some embodiments, the needle 52 can be disposed within a resilient sheath. In some embodiments, in response to the blood collection container pushing the resilient sheath distally, the needle 52 can puncture the resilient sheath and be inserted into the blood collection container.

[0051] In some embodiments, the vascular access device 10 can facilitate the taking of a blood sample from the second lumen 18 rather than through the first lumen 12. Accordingly, in some embodiments, a blood sample can be taken through a lumen dedicated for blood collection. In some embodiments, blood collection through the second lumen 18 can be used to perform blood collection to reduce the risk of thrombus formation within the vascular access device 10 and to reduce the risk of introducing microorganisms and other complications associated with repeated blood collection from a vascular access device such as a catheter. In some embodiments, the second lumen 18 can provide access to the blood collection device 50 and / or can facilitate the ability to draw blood through the opening 24 and / or valve into the vascular access device 10.

[0052] In some embodiments, a blood sample can be collected directly from the second lumen 18. For example, blood can flow into the second lumen 18 through the opening 24 and / or valve. The blood can then flow proximally through the second lumen 18, the second connector 28, and into the blood collection device 50. In some embodiments, in response to suction of the second lumen 18, blood can be pushed into the second lumen 18 and the blood collection device 50, while the first lumen 12 can be unaffected.

[0053] In some embodiments, the vascular access device 10 can facilitate positioning of the second lumen 18 within a large vein having a favorable catheter-to-vein ratio and blood flow. Thus, the vascular access device 10 can facilitate a high success rate of collecting a desired amount of blood without causing complications associated with a high catheter-to-vein ratio. In some embodiments, in response to placing the vascular access device 10 in the upper arm of a patient, blood can be obtained from a larger vein having better blood flow and utilization than veins typically accessed by peripheral intravenous catheters. In some embodiments, the second lumen 18 can be used for administration distally from the distal end 14 of the first lumen 12, which can reduce concerns about potentially incompatible medications.

[0054] In some embodiments, a method can include inserting the vascular access device 10 into the vasculature of a patient, for example, as shown in Figure 1B In some embodiments, the method can include collecting blood from the vasculature through the second lumen 18. In some embodiments, the method can include infusing a fluid into the vasculature through the first lumen 12 while collecting blood from the vasculature through the second lumen 18.

[0055] Referring now to Figures 1C-1G In some embodiments, the blood collection device 50 can include a tool 54. In some embodiments, the blood collection device 50 can be coupled to the second connector 28 and / or extend through the second lumen and out the opening 24 or valve. Thus, the tool 54 can access the vasculature 55, for example, as shown in Figure 1G In some embodiments, another suitable tool, such as a probe, can extend through the second lumen 18 and out the opening 24 or valve. In some embodiments, the vascular access device 10 facilitates access to a large vein having good blood flow because the tool 54 has more room to advance into the vein without scraping along the vein wall, which reduces the likelihood of causing damage by the tool 54.

[0056] In some embodiments, collecting blood from the vascular system through the second lumen 18 may include coupling a blood collection device to a second connector 28. In some embodiments, the blood collection device may include a device 54. In these and other embodiments, coupling the blood collection device to the second connector 28 may include inserting the device 54 into the second lumen 18 and allowing it to extend through an opening 24 or a valve.

[0057] like Figures 1D-1E As shown, in some embodiments, the blood collection device 50 may include a delivery device 56. In some embodiments, the device 54 may be delivered from the second cavity 18 and exited from the opening 24 or a valve via the delivery device 56. In some embodiments, the delivery device 56 may include a propulsion element 58. In some embodiments, the propulsion element 58 may include a tab or handle that a clinician may move to advance the device 54 distally and / or retract the device 54 proximally. In some embodiments, the propulsion element 58 may be coupled to the device 54. In some embodiments, the propulsion element 58 may slide along a slot 60 provided within the housing 62.

[0058] In some embodiments, the delivery device 56 can include any suitable delivery device and can be described, for example, in U.S. Patent Application No. 16 / 037,246, filed July 17, 2018, entitled “EXTENSION HOUSING A PROBE OR INTRAVENOUS CATHETER,” U.S. Patent Application No. 16 / 388,650, filed April 18, 2019, entitled “INSTRUMENT DELIVERY DEVICE HAVING A ROTARY ELEMENT,” U.S. Patent Application No. 16 / 037,319, filed July 17, 2018, entitled “MULTI-DIAMETER CATHETER AND RELATED DEVICES AND METHODS,” U.S. Patent Application No. 16 / 502,541, filed July 3, 2019, entitled “DELIVERY DEVICE FOR A VASCULAR ACCESS INSTRUMENT,” U.S. Patent Application No. 16 / 691,217, filed November 21, 2019, entitled “SYRINGE-BASED DELIVERY DEVICE FOR A VASCULAR ACCESS INSTRUMENT,” U.S. Patent Application No. 16 / 742,013, filed January 14, 2020, entitled “CATHETER DELIVERY DEVICE AND RELATED SYSTEMS AND METHODS,” and U.S. Patent No. 16 / 838,831, filed April 2, 2020, entitled “VASCULAR ACCESS INSTRUMENT HAVING A FLUID PERMEABLE STRUCTURE, AND RELATED DEVICES AND METHODS,” the entire contents of which are incorporated by reference.

[0059] Referring now to Figures 2A-2D According to some embodiments, a vascular access device 64 is shown.

In some embodiments, partition 35 can be integrally formed or integrally formed as a single unit with first extension tube 36. In some embodiments, partition 35 can be integrally formed or integrally formed as a single unit with catheter hub 30.

[0060] In some embodiments, second lumen 18 can include an annular space that can taper proximally or abruptly terminate at distal end 14 of first lumen 12. In some embodiments, one or more openings 24 or one or more valves can extend through a wall of catheter 40 to provide fluid communication between second lumen 18 and vasculature. In some embodiments, second lumen 18 can surround first lumen 12 and / or can be disposed laterally of first lumen 12, which can enable easy access of device 54 to vasculature.

In some embodiments, one or more openings 24 and / or one or more valves can extend through a wall of catheter 40 to provide fluid communication between second lumen 18 and vasculature. In some embodiments, openings 24 or valves can be arranged in a pattern along all or a portion of a length of catheter 40. In some embodiments, openings 24 and / or valves can be arranged in a linear pattern, for example, along a longitudinal axis of catheter 40 or radially around catheter 40. In some embodiments, second lumen 18 can be disposed laterally of first lumen 12, which can enable easy access of device 54 to vasculature.

[0063] Referring now to Figures 4A-4C , proximal portion 48 of catheter 40 can include a plurality of openings 24 (see, e.g., FIG. 2), a single opening 24 (see, e.g., FIG. 3), or a valve 68 (see, e.g., FIG. 4). Figure 4A Figure 4B Figure 4C ​​). In some embodiments, the plurality of openings 24 can provide a plurality of fluid paths for blood to enter the second lumen 18, which can facilitate successful blood collection by preventing occlusion when one or more of the openings 24 is pressed against a vein wall or is occluded by a thrombus or other device.

[0064] In some embodiments, the valve 68 can prevent blood from entering the second lumen 18, which can reduce the risk of infection. In some embodiments, the valve 68 can comprise a slit valve. In these and other embodiments, the valve 68 can be bidirectional. In some embodiments, the valve 68 can open outwardly in response to positive pressure and / or inwardly in response to negative pressure. In some embodiments, the proximal portion 48 of the catheter can comprise a plurality of valves 68. Referring now to Figures 4D-4E In some embodiments, the valve 68 can be configured to open in response to a predetermined pressure differential. In some embodiments, the valve 68 can open in response to a vacuum blood collection tube being coupled to the vascular access device (e.g., the vascular access device 10, the vascular access device 64, or the vascular access device 66).

[0065] Referring now to Figures 5A-5E According to some embodiments, a vascular access device 70 is shown. In some embodiments, the vascular access device 70 can be similar or identical to one or more of the following in one or more features and / or operations: Figures 1A-1G the vascular access device 10 of FIG. 1, Figures 2A-2D the vascular access device 64 of FIG. 6, and Figures 3A-3E the vascular access device 66 of FIG. 7.
