Abstract
The invention describes a sinus balloon catheter and methods of use. Specifically a sinus balloon catheter for dilating a sinus cavity lumen is provided with a tip that can be extended. The catheter comprises a guide tube with a proximal and distal end, a sleeve member, a balloon disposed upon the sleeve member and a rounded tip arranged at the distal end and extendable along with the extension of the sleeve member.
Claims20
A device for dilating a drainage pathway of a sinus cavity, comprising
- an inner guide member defining a first lumen;
- a sleeve member defining a second lumen, wherein the inner guide member is at least partially disposed within the second lumen;
- a balloon disposed on the sleeve member;
- a rounded tip member secured to a distal end of a wire that extends through the first lumen of the inner guide member and is disposed at a position that is distal to a distal tip of the sleeve member and a distal tip of the inner guide member;
- a balloon advancement member configured to advance the sleeve member along the inner guide member;
- and
- a spring that is secured at one end to a proximal end of the wire and provides a force urging the rounded tip member in a proximal direction,
- wherein the balloon is configured to advance off the distal tip of the inner guide member.

A method of treating a sinus cavity of a patient, comprising:
- providing a balloon dilation catheter comprising:
- an inner guide member defining a first lumen,
- a sleeve member defining a second lumen, wherein the inner guide member is at least partially disposed within the second lumen,
- a balloon disposed on the sleeve member,
- a rounded tip member secured to a distal end of a wire that extends through the first lumen of the inner guide member and is disposed at a position that is distal to a distal tip of the sleeve member and a distal tip of the inner guide member,
- a balloon advancement member configured to advance the sleeve member along the inner guide member, and
- a spring that is secured at one end to a proximal end of the wire and provides a force urging the rounded tip member in a proximal direction;
- directing the distal tip of the inner guide member into a head of a patient through a nostril;
- directing the distal tip of the inner guide member to a position near a sinus drainage pathway;
- advancing the sleeve member off the distal tip of the inner guide member and to a desired position within the sinus drainage pathway, wherein the rounded tip member remains next to the distal end of the sleeve member during the advancement of the sleeve member;
- and
- inflating the balloon to dilate tissue of the patient defining the desired position.
