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 catheter hub includes a distal assembly including a distal hub member adapted to be fixedly attached to an outer catheter and a proximal assembly including a proximal hub member adapted to be fixedly attached to an inner catheter disposed through the outer catheter. An elongate member connects the proximal and distal assemblies such that the proximal and distal assemblies can translate longitudinally relative to one another.

Abstract: A temporary vena cava filter retrieval apparatus includes an introducer sheath for establishing access into a vessel via a patient access site and a retrieval sheath having a diameter sufficiently small to pass through the introducer sheath and sufficiently large to accommodate a partially or fully uncollapsed filter.

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 hub assembly is provided for accommodating a medical professional to grip and manipulate two components of a catheter hub and move one component longitudinally relative to the other, then removably engaging the two components of the catheter hub to restrict movement there between. The two catheter hub components include a proximal hub and a distal hub. The proximal hub and the distal hub are configured to removably engage with one another. The proximal hub is affixed to a first catheter member, such as a multi-lumen catheter, while the distal hub is affixed to a second catheter member, such as a sheath. The first catheter member and the second catheter member are cooperatively engaged and concentric with one another. Relative movement of the proximal and distal hubs translates into relative movement of the first and second catheter members.

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: A detachment and retrieval mechanism for a central venous access filter includes a catheter body, and an outer sheath concentrically disposed about the catheter body. The outer sheath and the catheter body are moveable relative to one another. A filter member includes a first end coupled to the catheter body and a second end movable relative to the catheter body. The first end comprises a collar that is immovably coupled to the catheter body in a first state and movably coupled to the catheter body upon transition to a second state.

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.
