Abstract
A balloon catheter with improved balloon orientation includes a head, a catheter shaft extending from the head, and a balloon disposed on the catheter shaft opposite the head. The balloon of the present invention has an orientation such that the inflated width of the balloon is at least about 1.3 times the length of the balloon.
Claims29
A catheter having an interior and an exterior, the catheter comprising:
- a means for expansion having a proximal end, a distal end, a length dimension and a width dimension;
- a shaft including a distal end, a first lumen configured for fluid communication with a body cavity, and a second lumen configured for communication with the means for expansion;
- and
- wherein the width dimension of the means for expansion is greater than the length dimension of the means for expansion when the means for expansion is expanded.
A catheter comprising:
- a head having at least two openings through which fluid may be passed;
- a catheter shaft extending from the head, the catheter shaft having a first and second lumen, each of the lumens being in communication with at least one of the two openings, the catheter shaft further having an interior and an exterior;
- and
- a means for expansion having a first end attached to the catheter shaft and a second end attached to the catheter shaft, wherein the means for expansion has a width dimension at least about 1.4 times greater than the length dimension of the means for expansion when the means for expansion is expanded.
A catheter comprising:
- an elongate shaft having at least one lumen extending longitudinally therethrough, a distal end and a width dimension;
- and
- an expandable balloon, said balloon having a length dimension and a width dimension;
- wherein the width dimension of the balloon is larger than the length dimension of the balloon when the balloon is expanded.
A balloon catheter configured for placement through a stoma into a body cavity so that the catheter is maintained in the stoma, the catheter comprising:
- a head having at least one opening through which a fluid may be introduced;
- a catheter shaft extending from the head to a distal end the catheter shaft forming a passageway, said passageway having an interior;
- and
- an expandable member attached to the catheter shaft about the passageway so as to form a balloon, the balloon being in collapsed state when not expanded;
- wherein the balloon has a first end, a second end, a length dimension and a width dimension;
- and
- wherein the balloon extends radially outwardly from the catheter shaft when expanded, such that the width of the balloon is at least about 1.3 times the length of the balloon when expanded.
