Abstract

Abstract An aortic balloon catheter including an elongated tube device formed with a first lumen sized to communicate blood between an aortic lumen of an adult human patient and a location external to the aortic lumen. Mounted on the tube device is an inflatable balloon which is sized to resist or block blood flow through the aortic lumen. The associated method of using the aortic balloon catheter includes introducing the catheter into the aortic lumen of an adult human, positioning the first lumen and the balloon, inflating the balloon and withdrawing and perfusing fluids through the first lumen.

An aortic catheter, comprising: an elongated tube device to be inserted in an operative position to extend from a location external to a patient's body to a selected location in an aortic lumen of the patient and including a first blood lumen for communication of blood and having a first internal end arranged to be, when said tube device is in said operative position, in fluid communication with said selected location and extending to a first external end disposed at said external location; a balloon positioned on the exterior of said tube device and sized to inflate to resist blood flow within the aortic lumen; and said tube device includes an outer tube including a fluid lumen having a second internal end arranged to be, when said tube device is in said operative position, in fluid communication with the aortic lumen and extending to a second external end disposed at said external location, a pilot lumen in fluid communication on one end with the interior of said balloon and extending to a pilot external end at said external location and first and second tubes formed with the respective said first and fluid lumens, said tubes being positionable in different longitudinal positions relative to one another.
Claim 97
Dependent Claim 166 words
An aortic catheter, comprising: an elongated tube device to be inserted in an operative position to extend from a location external to a patient's body to a selected location in an aortic lumen of the patient and including a first blood lumen for communication of blood and having a first internal end arranged to be, when said tube device is in said operative position, in fluid communication with said selected location and extending to a first external end disposed at said external location; a balloon positioned on the exterior of said tube device and sized to inflate to resist blood flow within the aortic lumen and, when fully inflated, completely block flow of blood in said aorta; said tube device including a pilot lumen in fluid communication on one end with the interior of said balloon and extending to a pilot external end at said external location; and wherein the respective said first and second tubes are positionable in different longitudinal positions relative to one another.
Claim 98
Dependent Claim 166 words
An aortic catheter, comprising: an elongated tube device to be inserted in an operative position to extend from a location external to a patient's body to a selected location in an aortic lumen of the patient and including a first blood lumen for communication of blood and having a first internal end arranged to be, when said tube device is in said operative position, in fluid communication with said selected location and extending to a first external end disposed at said external location; a balloon positioned on the exterior of said tube device and sized to inflate to resist blood flow within the aortic lumen and, when fully inflated, completely block flow of blood in said aorta; said tube device including a pilot lumen in fluid communication on one end with the interior of said balloon and extending to a pilot external end at said external location; and wherein the respective said first and second tubes are positionable in different longitudinal positions relative to one another.
Claim 99
Dependent Claim 167 words
A perfusion apparatus for differentially perfusing first and second regions of a patient's body, comprising: an elongated tube device for insertion in an operative position to extend from a location external to the patient's body to axially spaced apart first and second selected locations in a flow relationship with respective first and second branch arteries of the patient's aorta leading to the respective first and second regions; said tube device including first and second blood flow lumens positioned to be, when said tube device is in said operative position, in fluid communication, respectively, between said external location and the respective said first and second selected locations; and a pump device for connection at said external location with said tube device and including a blood conditioning device for conditioning the blood to first and second conditions, said pump being operative to communicate the first and second condition blood, respectively, through said first and second lumens between said external location and the respective said first and second branch arteries.
Claim 100
Dependent Claim 167 words
A perfusion apparatus for differentially perfusing first and second regions of a patient's body, comprising: an elongated tube device for insertion in an operative position to extend from a location external to the patient's body to axially spaced apart first and second selected locations in a flow relationship with respective first and second branch arteries of the patient's aorta leading to the respective first and second regions; said tube device including first and second blood flow lumens positioned to be, when said tube device is in said operative position, in fluid communication, respectively, between said external location and the respective said first and second selected locations; and a pump device for connection at said external location with said tube device and including a blood conditioning device for conditioning the blood to first and second conditions, said pump being operative to communicate the first and second condition blood, respectively, through said first and second lumens between said external location and the respective said first and second branch arteries.
Claim 101
Dependent Claim 41 words
The perfusion apparatus of claim 90, wherein: said tube device includes a balloon positioned on the exterior of said tube device and sized to inflate to resist blood flow within the aorta between the respective said first and second branch arteries.
Claim 102
Dependent Claim 24 words
The perfusion apparatus of claim 90, wherein: said tube device includes respective first and second tubes forming the respective said first and second lumens.
Claim 103
Dependent Claim 24 words
The perfusion apparatus of claim 92, wherein: the respective said first and second tubes are positionable in different longitudinal positions relative to one another.
Claim 104
Dependent Claim 21 words
The aortic catheter of claims 44 or 45, wherein: said tube device is configured for use in an adult human aorta.
