Abstract
Abstract A catheter and method of use as an aortic balloon catheter having an integral expandable/collapsible lumen. The catheter comprises a main catheter body having a plurality of lumens extending therethrough, and further includes an expandable/collapsible lumen disposed thereabout and carried by the main catheter body. The expandable/collapsible lumen has a relatively large diameter when inflated with respect to the main catheter body, and is self-inflating by fluid pressure when the fluid flows therethrough. The large inflatable/collapsible lumen is attached at its distal end to the main catheter body and thus is carried therewith into a body vessel, and thus is also supported by the catheter body to avoid kinking. The catheter of the present invention is ideally suited for insertion into smaller access arteries for placement into larger arteries, such as an aortic balloon catheter which can be inserted into a smaller femoral artery and advanced into the ascending aorta to provide arterial return of oxygenated blood into the ascending aorta. The catheter further has an adjustable length. The present invention also achieves technical advantages as a catheter for insertion into any body vessel having a limited diameter and which is susceptible to trauma, such as a urethra.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
88 words
A catheter, comprising: a catheter body having a proximal end portion and a distal end portion; and a collapsible member disposed along at least a portion of said catheter body, said collapsible member having a distal end and defining a first lumen proximate said catheter body, said collapsible member being secured to said catheter body such that it can be advanced with said catheter body within a body vessel, wherein said collapsible member extends from said collapsible member distal end towards proximate said catheter body proximal end portion.
Claim 2
Dependent Claim
88 words
A catheter, comprising: a catheter body having a proximal end portion and a distal end portion; and a collapsible member disposed along at least a portion of said catheter body, said collapsible member having a distal end and defining a first lumen proximate said catheter body, said collapsible member being secured to said catheter body such that it can be advanced with said catheter body within a body vessel, wherein said collapsible member extends from said collapsible member distal end towards proximate said catheter body proximal end portion.
Claim 3
Dependent Claim
25 words
The catheter as specified in claim 1 wherein said collapsible member extends from said catheter body proximal end to proximate said catheter body distal end.
Claim 4
Dependent Claim
34 words
The catheter as specified in claim 1 further comprising a balloon member disposed about said catheter distal end portion, said catheter body having a second lumen communicating with the balloon for inflating said balloon.
Claim 5
Dependent Claim
22 words
The catheter as specified in claim 3 further comprising a third lumen extending through said catheter body and terminating at a port.
Claim 6
Dependent Claim
33 words
The catheter as specified in claim 4 further comprising a fourth lumen extending through said catheter body and terminating distal of said balloon member and between said third lumen port and said balloon.
Claim 7
Dependent Claim
30 words
The catheter as specified in claim 1 wherein said collapsible member comprises a sleeve with a thickness sufficiently thin such that said sleeve can be disposed against said catheter body.
Claim 8
Dependent Claim
25 words
The catheter as specified in claim 6 wherein said sleeve has substantially the same diameter as said catheter body when collapsed against said catheter body.
Claim 9
Dependent Claim
20 words
The catheter as specified in claim 7 wherein said sleeve has a wall thickness of less than about 0.01 inches.
Claim 10
Dependent Claim
49 words
The catheter as specified in claim 1 wherein said collapsible member is comprised of a first material and of a predetermined thickness such that fluid flow through said first lumen defined by said sleeve induces inflation of said collapsible member to define an increased diameter of said first lumen.
Claim 11
Dependent Claim
21 words
The catheter as specified in claim 6 wherein said sleeve is secured to at least one portion of said catheter body.
Claim 12
Dependent Claim
23 words
The catheter as specified in claim 10 wherein said sleeve is secured to said catheter body at a distal end of said sleeve.
Claim 13
Dependent Claim
26 words
The catheter as specified in claim 10 wherein said sleeve is secured along said catheter body from said sleeve proximal end to said sleeve distal end.
Claim 14
Dependent Claim
15 words
The catheter as specified in claim 1 wherein said collapsible member is comprised of polyethylene.
Claim 15
Dependent Claim
41 words
The catheter as specified in claim 1 further comprising a tubular body member, said catheter body being coupled to said tubular body member and being adjustable with respect to said tubular body member to adjustably establish a length of said catheter.
Claim 16
Dependent Claim
19 words
The catheter as specified in claim 14 wherein said catheter body is slidingly received within said tubular body member.
Claim 17
Dependent Claim
29 words
The catheter as specified in claim 15 wherein said tubular body member forms a passageway about said catheter body, said passageway being in fluid communication with said first lumen.
Claim 18
Dependent Claim
33 words
The catheter as specified in claim 15 wherein said collapsible member is connected to said tubular body member, wherein said collapsible member is adjustable in length with respect to said tubular body member.
Claim 19
Dependent Claim
32 words
The catheter as specified in claim 17 wherein said collapsible member is disposed about said tubular body member and is collapsible in the longitudinal direction with respect to said tubular body member.
Claim 20
Dependent Claim
78 words
A catheter comprising: a catheter body having proximal portion and a distal portion; and a collapsible member having a distal end and positioned along at least a portion of the catheter body and defining a lumen therein, the collapsible member expandable from a first collapsed condition to a second expanded condition in response to fluid flow through the lumen formed therein, said collapsible member extending from said collapsible member distal end towards proximate said catheter body proximal portion.
Claim 21
Dependent Claim
78 words
A catheter comprising: a catheter body having proximal portion and a distal portion; and a collapsible member having a distal end and positioned along at least a portion of the catheter body and defining a lumen therein, the collapsible member expandable from a first collapsed condition to a second expanded condition in response to fluid flow through the lumen formed therein, said collapsible member extending from said collapsible member distal end towards proximate said catheter body proximal portion.
Claim 22
Dependent Claim
93 words
A catheter, comprising: a catheter body having a proximal end portion and a distal end portion; an expandable balloon member disposed on said catheter body; and a collapsible member disposed along at least a portion of said catheter body, said collapsible member having a distal end and defining a first lumen proximate said catheter body, said collapsible member being secured to said catheter body such that it can be advanced with said catheter body within a body vessel, wherein said collapsible member extends proximal of said balloon towards said catheter proximal end portion.
Claim 23
Dependent Claim
93 words
A catheter, comprising: a catheter body having a proximal end portion and a distal end portion; an expandable balloon member disposed on said catheter body; and a collapsible member disposed along at least a portion of said catheter body, said collapsible member having a distal end and defining a first lumen proximate said catheter body, said collapsible member being secured to said catheter body such that it can be advanced with said catheter body within a body vessel, wherein said collapsible member extends proximal of said balloon towards said catheter proximal end portion.
