Many embodiments of an airway assembly and methods of using an airway assembly are disclosed. In one embodiment, an airway assembly includes an outer tube, an inner tube disposed coaxially with the outer tube, and a seal disposed on the inner tube. The seal is movable between a collapsed position and an expanded position where the seal engages an airway. Another embodiment is an airway assembly that includes an outer tube having a proximal portion and a distal portion, and an inner tube disposed coaxially with the outer tube. The inner tube has a proximal portion and a distal portion. The proximal portion of the outer tube has an outer diameter that is larger than an outer diameter of the distal portion of the outer tube.

A vascular filter assembly includes a catheter body having a self-expanding filter member coupled thereto. A sheath is disposed directly over the self-expanding filter member such that the self-expanding filter member is at least partially constrained from expansion in a first configuration within an interior space defined between the sheath and the catheter body. The sheath includes at least one aperture disposed through a wall thereof.

In some embodiments, an airway assembly may be used in a procedure that requires tracheal intubation. The airway assembly may include a first conduit, a sleeve, and a stent. The first conduit and the sleeve may be relatively flexible, facilitating insertion of the airway assembly in a body lumen (e. g. , an air passage way). The first conduit may function to deliver gases (e. g. , air) to the body lumen and consequently the patient. The first conduit may be positioned in the sleeve during use. The sleeve may be removably coupled to the first conduit. In certain embodiments, a sleeve may function to inhibit a stent from expanding until desired. In some embodiments, an elongated member may be positionable in the first conduit. The elongated member may be configurable to substantially retain a new shape upon deformation. The stent may be coupled towards the distal end of the first conduit.

A stent delivery system may be used to position a stent in a body lumen. An endoscope may be positionable in the stent delivery system facilitating direct visual observation during placement of the stent. The stent delivery system may include a first conduit, wherein the endoscope is positionable. A second conduit, wherein the first conduit is positionable, may function to releasably position the stent in the body lumen during use. The stent delivery system may include a lock that functions to inhibit movement of the first conduit relative to the second conduit during use. Retraction of the distal end of the second conduit, relative to the first conduit and the stent, may deploy the stent in a body lumen. Indicia, visibly positioned on the proximal end of the stent delivery system, may function to facilitate determination of an extent of deployment of the stent during use.

A self-centering central access catheter includes a multi-lumen catheter body, a first port associated with a first lumen, and a second port associated with a second lumen. The first and second ports are disposed proximate a distal end of the multi-lumen catheter. A diametrically expansible member is circumferentially coupled to a multi-lumen catheter body and positioned intermediate the first port and the second port. The diametrically expansible member comprises a first portion that is immovably fixed to the multi-lumen catheter body and a second portion that is movably coupled to the multi-lumen catheter body.

A biopsy needle assembly may include a sample needle, an actuator and a cutter. A sample needle may include a sample opening. A tissue sample may be positioned in the sample opening when the sample needle is inserted into tissue of a patient. The actuator may be activated to move the cutter relative to the sample needle and separate sample tissue in the sample opening from adjacent tissue. The biopsy needle assembly may be removed from the patient and the sample may be removed from the sample opening. In some embodiments, the sample needle may be inserted in tissue through an instrument (e.g., an endoscope). The biopsy needle assembly may include a sheath that inhibits a sample needle and a cutter from contacting the instrument when the biopsy needle is inserted in the instrument.
