Filed:

May 26, 2011

Appl. No.:

13/116660

Inventors:

John R. Drontle - Monticello MN, US
Anthony J. Hanson - Chaska MN, US

Assignee:

Entellus Medical, Inc. - Maple Grove MN

International Classification:

A61M 29/00

US Classification:

606196

Abstract:

A balloon dilation catheter includes a substantially rigid inner guide member and a movable shaft coupled to a balloon that is slidably mounted on the substantially rigid inner guide member. To treat a sinus cavity of a subject using the balloon dilation the substantially rigid inner guide member is advanced into a drainage pathway of the sinus (e. g. , frontal recess) of the subject via a nasal passageway. The shaft and balloon are advanced in a distal direction over the substantially rigid inner guide member to place the balloon in the drainage pathway. The balloon is inflated to expand or otherwise remodel the drainage pathway.

International Classification:

A61M 25/06

US Classification:

60416401

Abstract:

A system for accessing a sinus cavity of a subject includes an access tool configured to penetrate into the sinus cavity from a location external the subject. The system further includes an access sheath having a distal tubular portion, a lumen extending through the access sheath and the distal tubular portion and dimensioned to receive the access tool, the distal tubular portion comprising one or more cutting surfaces disposed about an external surface thereof. The one or more cutting surfaces may include a plurality of longitudinally oriented grooves for flutes disposed about the periphery of the distal tubular member.

US Classification:

600106, 600182

Abstract:

An endoscope includes a substantially rigid shaft having a distal end and a proximal portion, the shaft having a first lumen and a second lumen separate from the first lumen, the second lumen containing one or more objective lenses disposed at the distal end thereof. A housing is mounted on the proximal portion of the shaft, the housing including an eyepiece mount and a light input port. An image fiber bundle is disposed in the second lumen, the image fiber bundle extending proximally from adjacent the one or more objective lenses to the eyepiece mount. An illumination fiber bundle is disposed in the second lumen, the illumination fiber bundle extending proximally from the distal end of the shaft to the light input port.

Abstract:

A balloon dilation catheter includes a substantially rigid inner guide member and a movable shaft coupled to a balloon that is slidably mounted on the substantially rigid inner guide member. To treat a sinus cavity of a subject using the balloon dilation the substantially rigid inner guide member is advanced into a drainage pathway of the sinus (e.g., frontal recess or maxillary sinus) of the subject via a nasal passageway. The shaft and balloon are advanced in a distal direction over the substantially rigid inner guide member to place the balloon in the drainage pathway. The balloon is inflated to expand or otherwise remodel the drainage pathway.
