A medical device and method for the treatment of a sinus opening includes a handle, a guide catheter, a guide wire, a balloon catheter, a guide wire movement mechanism and a balloon catheter movement mechanism. The guide wire and balloon catheter are both disposed at least partially in the handle and catheter lumen. The guide wire movement mechanism is configured for advancement and retraction of the guide wire through the handle and catheter lumen by user operation of the guide wire movement mechanism. The guide wire movement mechanism includes an integrated guide wire locking and rotation mechanism configured for rotation of the guide wire and for securely locking and unlocking the guide wire to the guide wire movement mechanism. The balloon catheter movement mechanism is configured for advancement and retraction of the balloon catheter through the handle and catheter lumen by user operation of the balloon catheter movement mechanism.
摘要:
The invention is an endoscopic method for viewing a target portion of a patient's anatomy with access through the oral or nasal cavity. The method includes adjusting a variable direction of view endoscope to a direction of view of between about 0 degrees and 20 degrees relative to a longitudinal axis of the endoscope and a shaft orientation pointing toward the target portion of the patient's anatomy. The endoscope is then introduced straight into the oral or nasal cavity of a patient until the endoscope is positioned in the back of the cavity. The direction of view is adjusted to view the target portion of the patient's anatomy.

摘要:
A probe including an elongate body defining a distal region adapted to be bent into a loop and an inflatable tissue coagulation body supported on the elongate body distal region.
摘要:
A probe that may be used to create circumferential lesions in body tissue and, in some implementations, may also be used to perform mapping functions. The probe includes a collapsible/expandable structure that supports electrodes or other operative elements against the body tissue.
