Guidewire-management devices and systems thereof are disclosed herein. A guidewire-management device can include a guidewire, a first sleeve, and a second sleeve. The first sleeve can be configured for distally feeding the guidewire out of the guidewire-management device. The first sleeve can also be configured for proximally feeding the guidewire into the guidewire-management device. The second sleeve can be proximal of the first sleeve in the guidewire-management device. The second sleeve can be configured for feeding the guidewire in concert with the first sleeve. At least a length of the guidewire extending between the first sleeve and the second sleeve can be disposed within a sterile barrier configured to maintain sterility of the guidewire.

A guidewire includes a guidewire shaft and an inflatable element arranged at a distal end of the guidewire shaft. At least a portion of the guidewire shaft is formed of metal, and the guidewire shaft includes a lumen that fluidly communicates with an interior of the inflatable element. The inflatable element is operable to transition between a deflated state in which the inflatable element is configured to pass through an isthmus of a Eustachian tube (ET), and an inflated state in which the inflatable element is configured to dilate the ET.

A method for managing a guidewire in preparation for a surgical operation, comprising attaching a block of resilient polymer to a coiled tube which contains a guidewire; attaching to the block of resilient polymer a card having printed information concerning the guidewire on a planar surface of the card; removing the guidewire from the coiled tube; removing the block of resilient polymer from the coiled tube while keeping the card having printed information attached to the block of resilient polymer; coiling the guidewire into a flat spiral form; capturing, in a slot formed in the block of resilient polymer, a plurality of portions of the guidewire, which portions are adjacent to and parallel with each other, thereby maintaining the guidewire in the flat spiral form.

An apparatus for assisting in the introduction of a flexible wire into a device having a comparable sized lumen. An exemplary apparatus includes a first portion having a distal end, a proximal end, a slot and a lumen exposed at the distal end, the proximal end and the slot, and a second portion having a distal end, a proximal end, a slot and a lumen exposed at the distal end, the proximal end and the slot of the second portion. The second portion is slidably and rotatably received with the lumen of the first portion. A gripping device is attached at the proximal end of the second portion. The gripping device causes at least a portion of the proximal end of the second portion to have a reduced inner diameter when a gripping force is applied to the gripping device.

A stylet for use in guiding a distal tip of a catheter to a predetermined location within the body of a patient. In one embodiment the stylet is configured for use within a lumen of the catheter and comprises a core wire, an ECG sensor, and a magnetic assembly. The ECG sensor senses an ECG signal of a patient when the stylet is disposed within the lumen of the catheter and the catheter is disposed within the body of the patient. The magnetic assembly includes at least one element capable of producing a magnetic or electromagnetic field for detection by a sensor external to the patient. In another embodiment, the stylet includes a pre-shaped distal segment that is deflected with respect to a more proximal portion of the stylet, which in turn causes a distal segment of the catheter to be deflected when the stylet is received within the lumen.

A rooter includes a rotatable element, an actuator for causing the rotatable element to rotate, and a coupling feature for rotatably coupling an elongated medical instrument to the rotatable element. The rotatable element may be at least partially contained within the interior of a housing or another element that remains substantially stationary as the actuator causes the rotatable element to rotate. The rooter may be used with a variety of elongated medical instruments, such as wires, mascerators, needles, drill bits, trocars, catheters, tubes and other elongated instruments that are used to enable or effect medical procedures within the body of a subject. The rooter may be used for a variety of purposes, including, without limitation, the introduction of an elongated medical instrument into the body of a subject or its removal from the subject's body; removing, breaking up, or eliminating obstructions (e.g., blood clots, plaques, etc.) from the body of a subject; and obtaining samples from a subject's body.

Embodiments disclosed herein are directed to a catheter insertion device including a proximal housing rotatably coupled to a distal housing. Embodiments further include a catheter hub rotatably coupled to the distal housing and a catheter advancement carrier disposed therebetween. The device allows a clinician to rotate the catheter hub, or the proximal or distal housings relative to each other such that a slider, needle retraction button, catheter hub wings, or extension arm can be positioned conveniently depending on the location of the insertion site, e.g. left or right radial artery. Further, the catheter advancement carrier can include detachable tabs to allow the device to lay adjacent the skin surface of the patient, depending on left-side or right-side configuration of the device. The device can further include a gate structure to allow distal ingress of the slider assembly into the housing slot, facilitating manufacture of the device.

A medical device may comprise a handle and a flexible sheath extending from the handle. The sheath may include a first chamber configured to receive a first agent and a second chamber configured to receive a second agent. Each of the first chamber and the second chamber may be disposed in a distal portion of the sheath. The sheath may also include a first piston received within the first chamber and a second piston received within the second chamber and at least one actuation element configured to transmit a force from the handle to each of the first piston and the second piston. When the handle is in a first configuration, the first agent may be maintained within the first chamber and the second agent is maintained within the second chamber. When the handle is in a second configuration, the first agent may be released from the first chamber to mix with the second agent.
