Abstract
The present invention relates to balloon catheters wherein at least the proximal end of the balloon thereof is invertedly attached to the catheter shaft. Other aspects of the balloon catheters will have both ends of the balloon inverted. The present invention contemplates numerous other variations and modifications. As such, other aspects of the present invention will be apparent upon reading the remainder of the disclosure.
Claims23
A catheter comprising:
- a means for expansion having a proximal end and a distal end;
- and
- an elongate shaft having a distal end, a first lumen adapted for fluid communication and a second lumen adapted for fluid communication with the means for expansion;
- wherein each end of the means for expansion is invertedly attached to the catheter.
A balloon catheter comprising:
- a head having at least two openings through which fluid may be passed;
- a shaft extending from the head, the shaft having a first and second lumen disposed in communication with the at least two openings, the shaft further having an interior and an exterior;
- and
- a sleeve having a proximal end and a distal end, wherein at least the proximal end of the sleeve is attached to the shaft in a folded under fashion;
- wherein an expandable cavity is formed between the sleeve and the shaft.
A catheter comprising:
- a head;
- an elongate shaft having at least a first lumen extending longitudinally therethrough, and a distal end;
- and
- an expandable sleeve having a first end and a second end;
- wherein the ends of the sleeve are attached to the shaft in a folded under manner such that the ends of the sleeve are at least significantly hidden when the sleeve is expanded.
A balloon catheter configured for placement through a stoma into a body cavity, the balloon catheter comprising:
- a head having at least one opening through which a fluid may be introduced;
- a catheter shaft extending from the head, the catheter shaft having a distal end, an exterior and a wall defining a passageway through the interior;
- and
- a sleeve having a first end and a second end, the ends being invertedly attached to the catheter shaft about the passageway so as to form an expandable balloon, such that the ends of the sleeve are substantially encompassed by the balloon when the balloon is expanded.
