Abstract: A combined multi-lumen central access catheter and an embolic filter including ports proximal and distal the filter for fluid infusion and/or pressure sensing and infusion ports in the catheter to permit infusion of bioactive agents, flushing agents and/or contrast agents. The embolic filter may be removably coupled to the multi-lumen catheter for temporary placement and retrieval under recommended indications.

Abstract: 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. The stent may function to inhibit the body lumen from collapsing.

Abstract: A central access vena cava filter catheter having a multi-lumen catheter body with plural longitudinally extending parallel lumens within the single catheter body, a vena cava filter member disposed at a distal end of the catheter body and an outer sheath concentrically disposed about the multi-lumen catheter body and the vena cava filter member. The vena cava filter member may be removably coupled to the multi-lumen catheter for temporary placement and retrieval under recommended indications.

Abstract: A method of using an airway assembly in an airway generally comprises providing an airway assembly having an outer tube, an inner tube disposed coaxially with the outer tube, and a seal disposed on the inner tube. The seal is inserted into the airway. The seal is moved from a collapsed position to an expanded position where the seal engages the airway. Fluid is moved through the inner tube and the seal. An additional embodiment provides the airway assembly placed in a first status. The airway assembly is inserted into an airway when the airway assembly is in the first status. The outer tube is moved with respect to the inner tube to place the airway assembly in a second status. The outer tube is moved with respect to the inner tube to place the airway assembly in a third status.

Abstract: 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.

Abstract: 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.

Abstract: An attachment configuration for a vascular filter assembly including a self-expanding filter member attached to a catheter body and constrained from expansion in a first configuration by a constraining sheath is presented. The attachment configuration includes an outer tube of material that is overlaid over an end of the filter member and bonded to the catheter body through cutouts disposed through the end of the filter member.

Abstract: 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.

Abstract: 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.

Abstract: An airway assembly may be used in a procedure that requires instrumentation to be inserted in an air passage of a patient. The airway assembly may include a reinforced and flexible first conduit, an expandable member, a second conduit and a third conduit. The second and third conduit may couple to an outer surface of the first conduit. Coupling the second and third conduits to an outer surface of the first conduit may allow the first conduit to have an unobstructed lumen that facilitates insertion of instruments into a patient. Fluid may be removed through the second conduit. Ventilation of a patient may be performed through the third conduit. The expandable member may seal against the air passage and inhibit fluid from passing from a first region to a second region and/or inhibit fluid from passing from the second region to the first region.
