Abstract

Claims (21)

1 . A method for stabilizing a catheter at a patient, comprising:

providing a frame, wherein the frame includes:

a catheter hub coupled to the catheter,

a stabilization hub,

a flexible lateral member defining a lumen and extending between the catheter hub and the stabilization hub, and

a needle, wherein

the catheter hub further comprises:

a fluidic channel within the catheter hub, wherein the fluidic channel comprises a fixed turnabout portion within the catheter hub and is configured to direct flow toward the distal region of the catheter hub and wherein the fluidic channel fluidically communicates with the catheter and passes through the lumen of the flexible lateral member,

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a needle shield configured to capture at least a portion of the needle as the needle is withdrawn from the catheter hub;

inserting the catheter into the patient at an insertion site with the frame operating in a folded configuration by way of the flexible lateral member, wherein the stabilization hub is retained in an angularly displaced position relative to the catheter hub;

transitioning the frame to an unfolded configuration, wherein the stabilization hub is at least partially reverted from the angularly displaced position relative to the catheter hub; and

securing the frame to the patient at first and second anchoring points distributed about the insertion site, thereby stabilizing the catheter at the patient.

2 . The method of claim 1 , wherein the needle shield provided in the step of providing the frame is a spring clip.

3 . The method of claim 2 , further comprising withdrawing the needle from the catheter and the catheter hub, wherein at least a portion of the spring clip is positioned in a proximal region of the catheter hub, and wherein the spring clip is configured to capture at least a tip of the needle during the withdrawing step.

4 . The method of claim 2 , wherein the spring clip is coupled to an outer region of the catheter hub during the providing step.

5 . The method of claim 2 , wherein the catheter hub further comprises a recess, and wherein the spring clip is within the recess during the providing step.

6 . The method of claim 1 , further comprising withdrawing the needle from the catheter and the catheter hub, wherein the needle further comprises a catch configured to engage the needle shield during the withdrawing step.

7 . The method of claim 1 , wherein the needle extends through the septum and a portion of the fixed turnabout portion during the providing step.

8 . The method of claim 1 , wherein the catheter hub provides the first anchoring point on the patient and the stabilization hub provides the second anchoring point on the patient during the securing step.

9 . The method of claim 8 , wherein the securing step further comprises positioning the catheter hub and the stabilization hub on opposite sides of the insertion site.
