An integrated catheter assembly includes a housing member, an outer lumen member extending from the housing member, and a needle member having a needle slidably or movably coupled to the housing member, wherein the needle can be extended beyond the outer lumen member. Once a flash of blood is confirmed the needle member is uncoupled from the housing member and removed from within the patent's vein or artery. Two separate passageways are established by the inner and outer lumen members passing through the housing member. In this manner the two passageways permit the simultaneous flow of fluids into or out of a body from a single target site, such as blood, medications and other fluids.

Integrated catheter assembly

An integrated catheter assembly includes a housing member, an outer lumen member extending from the housing member, and a needle member having a needle slidably or movably coupled to the housing member, wherein the needle can be extended beyond the outer lumen. Once a flash of blood is confirmed the needle member is uncoupled from the housing member and removed from within the patient's vein or artery. A non-removable inner lumen member is connected to the housing member. The distal end of the outer lumen is sealed against the distal end of the inner lumen and includes at having at least one aperture to transfer blood out of the patient to the dialysis machine. The integrated catheter assembly therefore receives and delivers blood through a single injection site.

A method of using an integrated catheter assembly includes a housing member, an outer lumen member extending from the housing member, and a needle member slidably or movably coupled to the housing member, wherein the needle member can be extended beyond a first port of the outer lumen member in a first position and concealed in the outer lumen member in a second position. The outer lumen member has a side port between its first and second ports such that when the needle is extended in the first position and inserted into an arteriovenous fistula, blood from the arteriovenous fistula flashes into the needle member, is diverted through a relief port of the needle member out the side port of the outer lumen member for delivery to a dialysis machine. The assembly further includes an inner lumen member that is disposable through the housing member to extend out from the same the outer lumen member to provide dialyzed blood from the machine. The assembly therefore receives and delivers blood through a single injection site.

Integrated catheter assembly and method of use

An integrated catheter assembly includes a housing member, an outer lumen member extending from the housing member, and a needle member having a needle slidably or movably coupled to the housing member, wherein the needle can be extended beyond the outer lumen. Once a flash of blood is confirmed the needle member is uncoupled from the housing member and removed from within the patent's vein or artery. An inner lumen member having an elongated member housing an inner lumen is then connected to the housing member. The integrated catheter assembly therefore receives and delivers blood through a single injection site.
