A system for accessing a body cavity, such as a paranasal sinus, may include a sinus access member and a handle. The sinus access member may include a rigid support tube, a curved shape memory member slidably disposed at least partially within the rigid support tube, a flexible tube slidably disposed over at least part of the curved shape memory member, and proximal coupling end. The handle may include an engagement mechanism at a distal end for releasably attaching to the proximal coupling end of the sinus access member, a housing for gripping with a hand, a curving slider for extending and retracting the curved shape memory member, and an extension slider for extending and retracting the flexible tube relative to the curved shape memory member and the rigid support tube. The handle may be reusable, and the sinus access member may be disposable.

Modular body cavity access system

A device for visualizing and providing suction for a surgical procedure in an ear may include a handle, a main shaft extending from the handle, an imaging sensor at a distal end of the main shaft, a light source at the distal end of the main shaft, and a suction shaft extending from the handle. The device may also include a spring coupled with the suction shaft and/or the handle, such that when the suction shaft is advanced in a distal direction and then released, the suction shaft retracts automatically. The suction shaft may have a distal curved portion, and the device may have a thumb depress portion that allows a user to spin the suction shaft to suction in different directions. Some embodiments may include a suction shaft with a sharp distal tip that is configured for placing an ear tube in the tympanic membrane.

Ear visualization and treatment system

A seeker device for facilitating access to a desired location within an ear, nose, throat or other location in a body may include a proximal shaft, an elastic distal portion, and an atraumatic distal tip. The elastic distal portion has a default shape with at least one curve to facilitate advancement of a distal end of the elastic distal portion through various anatomical passageways, toward the desired location. In some embodiments, the seeker device may be paired with a dilator device, to perform a dilation procedure on an anatomical structure in the ear, nose, throat or other part of the body. In other embodiments, the seeker device may be paired with a flexible endoscope, to facilitate visualization of an anatomical structure or area.

Seeker with dilator

An ear endoscope device for use in a surgical procedure in an ear includes a handle, a visualization shaft extending from the handle, a tool guide extending from the handle parallel to the visualization shaft and configured to guide a tool into the ear with the visualization shaft, an imaging sensor at a distal end of the visualization shaft, and a light source. In some embodiments, the ear endoscope is combined with a suction device. In other embodiments, it may be combined with another tool.

Ear visualization system

A device, including a straight support element, a curved support element slidably coupled to the straight support element, and a rigid straight support element slidably coupled to the curved support element, the straight support element having a first rigidity, the curved support element having a curved portion having a second rigidity greater than the first rigidity, the rigid straight support element having a third rigidity greater than the second rigidity, when the rigid straight support element overlaps the curved portion of the curved support element an overlapped portion of the curved portion conforms to a straight shape of the rigid straight support element, when the curved portion overlaps the straight support element, an overlapped portion of the straight support element conforms to a curved shape of the curved portion, the curved portion having a rectangular cross section.
