A pump cartridge for mounting on a drive rotor includes a roller assembly having first and second hubs maintained in a spaced apart relationship and defining an axis, and a plurality of planetary rollers arranged in a circumferentially spaced orientation about the axis, the rollers mounted to the hubs displacement radially outward. One or more compressible tubing lines are interposed between the rollers and an interior wall of the pump cartridge housing. The housing and the first and second hubs collectively define a passageway through which a spreader on the drive rotor extends and may be rotated relative to the roller assembly to displace the rollers radially outward to thereby compress the tubing lines against the interior wall. A coupling feature on the first hub engages a roller driving feature of the rotor, so that rotation of the rotor causes rotation of the roller assembly about the axis.

Disclosed is an inter- and intra-catheter flow device for the management of vascular bleeding disorders that provide a liquid flow-pass between proximal and distal balloons for bridging the circulation between the upper and lower segments of a hemorrhaging artery or blood vessel, while blocking the blood flow to the hemorrhaging middle segment(s) of the artery or blood vessel between the two or more balloons. When only one balloon is inflated, these devices can create a pressure gradient between proximal or distal and middle segments of the artery or blood vessel. These devices are useful for controlling proximal artery blood pressure, preventing distal ischemia-reperfusion injury, identifying the bleeding location, controlling the bleeding, repairing and remodeling vascular structures, extending resuscitative endovascular balloon occlusion of the aorta (REBOA) use duration, and performing fluid resuscitation.

An introducer sheath for the insertion of a medical device into a blood vessel having an expandable sheath. The sheath has a length, a thickness, and proximal and distal ends. The expandable sheath has a frame extending longitudinally between the proximal and the distal ends, and having an exterior surface and an interior surface that forms an interior lumen along the length of the frame. The frame is configured to achieve an expanded state and a contracted state, the expanded state forming an expanded cross-section in the lumen for passing a medical device therethrough. The frame has a smooth coating about the exterior surface and protrusions extending into the lumen along the interior surface. The introducer sheath can be introduced into a patient in the contracted state, with the distal end of the introducer sheath prevented from moving in the proximal direction by an abutment against a dilator end surface.

A nasopharyngeal airway device includes an elongate body having a distal end and a proximal end. The elongate body has an outer surface defining one or more open channels extending along the elongate body. The nasopharyngeal airway device includes a securement component securely coupled to the elongate body. The securement component is configured to secure the nasopharyngeal airway device within a nostril of an individual.

Sinusitis and other disorders of the ear, nose and throat are diagnosed and/or treated using minimally invasive approaches with flexible or rigid instruments. Various methods and devices are used for remodeling or changing the shape, size or configuration of a sinus ostium or duct or other anatomical structure in the ear, nose or throat; implanting a device, cells or tissues; removing matter from the ear, nose or throat; delivering diagnostic or therapeutic substances or performing other diagnostic or therapeutic procedures. Introducing devices (e.g., guide catheters, tubes, guidewires, elongate probes, other elongate members) may be used to facilitate insertion of working devices (e.g. catheters e.g. balloon catheters, guidewires, tissue cutting or remodeling devices, devices for implanting elements like stents, electrosurgical devices, energy emitting devices, devices for delivering diagnostic or therapeutic agents, substance delivery implants, scopes etc.) into the paranasal sinuses or other structures in the ear, nose or throat, Specific devices (e.g., tubular guides, guidewires, balloon catheters, tubular sheaths) are provided as are methods for manufacturing and using such devices to treat disorders of the ear, nose or throat.

Devices for nasal insertion may include an open-ended tubular element which extends along a central tube axis between a first end and a second end, the first end being larger than the second end, and in which the tubular element includes at least one spiral strut extending from the first end to the second end, and/or a nodule having an internal face, a rounded external face, and a stalk extending from the internal face and terminating in an anchor sufficiently larger than a receptacle in the tubular element and sufficiently deformable as to be pressed through the receptacle to affix the nodule to the tubular element.
