Abstract
Devices and methods for locating sinus ostia and positioning a guide wire within the sinus ostia. The subject devices comprise a shaft having a distal end, a proximal end, a curved region located between the distal and proximal ends, and an interior channel, an extensible and retractable guide wire movably mounted within the interior channel and a probe tip joined to the guide wire. Certain devices further include expandable portions for engaging and treating body anatomy.
Claims21
-56. (canceled)
An apparatus comprising:
- (a) a handle assembly;
- (b) an elongate body comprising a proximal portion, a distal portion, wherein the elongate body defines an inflation lumen, wherein the proximal portion of the elongate body defines a longitudinal axis, wherein the elongate body extends distally from the handle assembly, wherein the distal portion of the elongate body terminates into a distal end dimension to be interested within a nasal cavity;
- and
- (c) a balloon attached to the distal portion of the elongate body, wherein the balloon is in fluid communication with the inflation lumen of the elongate body, wherein the balloon is configured to transition between a deflated configuration and an inflated configuration, wherein the balloon comprises an asymmetrical profile relative to a plane extending along a length of the distal portion of the elongate body.
The apparatus of 57, wherein the balloon terminates prior to the distal end of the distal portion of the elongate body.
An apparatus comprising:
- (a) an elongate body comprising a proximal portion, a distal portion, wherein the proximal portion of the elongate body defines a longitudinal axis, wherein the distal portion of the elongate body terminates into a distal end dimensioned to be interested within a nasal cavity;
- and
- (b) a balloon attached to the distal portion of the elongate body, wherein the balloon is configured to transition between a deflated configuration and an inflated configuration, wherein the balloon comprises an asymmetrical profile relative to a plane extending along a length of the distal portion of the elongate body.
An apparatus comprising:
- (a) an elongate body comprising a semi-rigid proximal portion, a distal portion, wherein the elongate body defines an inflation lumen, wherein the semi-rigid proximal portion of the elongate body defines a longitudinal axis, wherein the semi-rigid proximal portion of the elongate body is attached to the handle assembly, wherein the distal portion of the elongate body terminates into a distal end dimension to be interested within a nasal cavity;
- and
- (b) a balloon attached to the distal portion of the elongate body, wherein the balloon is in fluid communication with the inflation lumen of the elongate body, wherein the balloon is configured to transition between a deflated configuration and an inflated configuration, wherein the balloon comprises an asymmetrical profile relative to a plane extending through a central axis of the distal portion of the elongate body.
