Abstract
Systems and methods to provide an intravenous device having flashback capabilities and features to permit a flashback notch of an introducer needle to bypass a septum of the device without incurring an undesirable contact between the flashback notch of the introducer needle and a related contact surface of the septum.
Claims20
An intravascular device, comprising:
- a catheter adapter having an inner surface and an outer surface;
- a septum seated within the inner surface of the catheter adapter, the septum having an opening defined by a plurality of leaves, each leaf having a contact surface;
- and
- a cannula having a notch for providing a flashback signal, the notch comprising an opening having at least one of a width and a length configured to prevent the contact surface from substantially penetrating the notch.
1 more element
An intravascular device, comprising:
- a catheter adapter having an inner surface and an outer surface;
- a septum seated within the inner surface of the catheter adapter thereby dividing a lumen of the catheter adapter into a proximal chamber and a distal chamber, the septum having an opening defined by a plurality of leaves;
- a cannula having a notch for providing a flashback signal;
- and
- a feature for preventing a portion of the plurality of leaves from substantially penetrating the notch.

A method for preventing undesirable contact between a septum of an intravascular device and a notch of a needle, the method comprising:
- providing a catheter adapter having an inner surface and an outer surface;
- seating a septum within the inner surface of the catheter adapter thereby dividing a lumen of the catheter adapter into a proximal chamber and a distal chamber, the septum having an opening defined by a plurality of leaves;
- providing a cannula having a notch for providing a flashback signal;
- and
- providing a feature for preventing a portion of the plurality of leaves from substantially penetrating the notch.
