Power injection catheters and method of injecting
First Claim
1. A catheter comprising:
- an elongated catheter body including a proximal end and a distal end, the body defining one lumen;
a plurality of extension tubes, each of the plurality of extension tubes comprising a lumen in fluid communication with the one lumen of the catheter body; and
wherein a first of the plurality of extension tubes is configured for performing power injection and a second of the plurality of extension tubes includes a proximal valve.

Abstract
Power injection catheters for high flow rate delivery of fluids are disclosed. In one embodiment, a catheter may include a body defining one lumen and a plurality of extension tubes each comprising a lumen in fluid communication with the one lumen of the catheter body. Further, an extension tube may be configured for performing power injection and an extension tube may include a proximal valve. In another embodiment, a catheter may comprise a plurality of lumens and extension tubes, each of the extension tubes comprising a lumen in fluid communication with one lumen of the catheter body, respectively. At least one extension tube may be configured for performing power injection and at least one extension tube may include a proximal valve. Such catheters may include a pressure relief mechanism for preventing overpressurizing of the catheter. A method of injecting a fluid into a patient'"'"'s body is disclosed.

29. A method of injecting a fluid into a patient'"'"'s body, comprising:
-
inserting a catheter into a circulatory system of a patient, the catheter including at least one lumen and including at least one extension tube comprising a proximal valve, the at least one extension tube capable of fluid communication with the at least one lumen of the catheter;
wherein the proximal valve is structured to inhibit fluid flow for pressures developed within the at least one lumen of the catheter below a selected aspiration pressure;
developing a pressure exceeding the selected aspiration pressure within the at least one lumen of the catheter by injecting a fluid into the at least one lumen of the catheter; and
substantially preventing fluid flow through the at least one extension tube comprising the proximal valve. - View Dependent Claims (30, 31, 32, 33, 34)
