Abstract
A catheter assembly may include a catheter adapter having a proximal end, a distal end, and a lumen extending therebetween. A wedge adapter may be retained within the lumen and have a wedge coupled thereto. The wedge may be configured to retain an end of a catheter such that a tip of the catheter extends through the distal end of the catheter adapter. A control feature may extend through an end or side wall of the catheter adapter. The control feature may be configured to manipulate the wedge to control a position of the tip of the catheter to open a fluid path within a vasculature.
Claims10
A catheter assembly to open a fluid path, comprising:
- a catheter adapter configured to be (i) secured exterior to a patient and (ii) remain external to the patient, the catheter adapter comprising a proximal end, a distal end, and a lumen extending along a longitudinal axis therebetween;
- a wedge adapter retained within the lumen of the catheter adapter and having a wedge coupled thereto, wherein the wedge is configured to be retained within the catheter adapter and external to the patient, wherein the wedge is configured to retain a proximal end of a catheter within the catheter adapter and external to the patient such that a portion of the catheter extends from the distal end of the catheter adapter, wherein the portion of the catheter that extends from the distal end of the catheter adapter is configured to remain in the patient while the catheter adapter is secured exterior to the patient, wherein a portion of the wedge is positioned within the proximal end of the catheter;
- and
- a control feature extending from the wedge adapter and through one of the proximal end and a side wall of the catheter adapter, wherein the control feature is configured to manipulate the wedge to control a position of a tip of the catheter to open a fluid path.
