Embodiment Construction

[0041] refer to figure 1 , shows a perspective view of an embodiment of a catheter insertion device 100 including a catheter set 102 and an insertion set 104 . Insertion set 104 may be separated from catheter set 102 as catheter 106 is partially inserted into the patient's vasculature. The catheter set 102 also includes an extension line assembly 108 in fluid communication with the catheter 106 . Extension line assembly 108 may be connected to a fluid source or aspirator. Insertion set 104 includes a handle 110 that is initially connected to catheter set 102 and facilitates insertion of catheter 106 into the patient's vasculature.

[0042] refer to Figure 2A , shows an exploded view of the various components of catheter set 102 of catheter insertion device 100 . refer to Figure 2B , shows a partially transparent perspective view of the assembled catheter set 102 of the catheter insertion device 100 . At its proximal region, catheter set 102 includes an extension line a...

Abstract

A catheter insertion device that allows for single-handed insertion of the catheter within the vasculature of the patient is disclosed. The catheter insertion device includes a handle, a needle cannula partially within the handle, a guidewire partially within the handle and the needle cannula, and a first actuator connected to the handle and the guidewire. The first actuator is movable in a proximal direction relative to the handle to cause the guidewire to move in a distal direction away from the handle, and is movable in a distal direction relative to the handle to cause the guidewire to move in a proximal direction towards the handle. The catheter insertion device can also include a needle support that stabilizes the needle cannula during insertion of the needle cannula into a patient.
