A surgical sheath adapted for use in the nasal cavity has an elongated hollow body made of a braided material having interstitial spaces with a dimension of 0.25 mm to 1.50 mm. The interstitial spaces filled with a filling material, such as silicone. The sheath has a low profile configuration during placement into the naris, and may be stretched into an expanded configuration. In methods of placing the sheath in the naris, the sheath is folded and then pulled into the naris using a surgical tool.

The present invention generally relates to a medical device and a method of using a medical device. Specifically, the invention relates to a tube introducing device designed to introduce catheters, endoscopes and the like medical devices into organs and body lumens during procedures such as esophageal manometry, esophageal pH tests, and the placement of trans-nasal feeding tubes and a method of use thereof.

A medical tool includes a rotatable hollow tube and one or more electrical wires. The rotatable hollow tube is defining a working channel therein for insertion of a medical instrument into a cavity of a patient body. The one or more electrical wires traverse the working channel for exchanging electrical signals with one or more electronic devices located at a distal end of the rotatable hollow tube. The working channel has a non-circular cross section for passing both the medical instrument and the one or more electrical wires, and for allowing rotation of the rotatable hollow tube relative to the medical instrument located inside the working channel in the presence of the one or more electrical wires.

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.
