Catheter having integral expandable/collapsible lumen
First Claim
1. A catheter comprising:
- a catheter body, wherein the catheter body is elongated and hollow, the catheter body having a distal and a proximal end, wherein the catheter body comprises a rigid member with a proximal and a distal end, and;
a hollow support member coupled to the catheter body having a distal and proximal end, wherein the proximal end of the support member is coupled to the distal end of the catheter body and wherein the proximal end of the support member is coupled to the distal end of the rigid member; and
a collapsible lumen having a distal and proximal end, wherein the proximal end of the lumen is coupled to the distal end of the support member, wherein the lumen is flexible relative to the catheter body and has a plurality of openings to allow fluid to flow through the lumen such that the velocity of the fluid flow through the lumen is minimized.

Abstract
A catheter and method of use may include an aortic balloon catheter having an integral expandable/collapsible lumen. The catheter comprises a main catheter body having a either a single or 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 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.
