Abstract: An apparatus includes a shaft, an expandable dilation member, and a bulbous tip. The shaft has a first outer cross-sectional dimension. The dilation member is positioned proximal to the distal end of the shaft. The dilation member is operable to transition between a non-expanded configuration and an expanded configuration. The dilation member is sized to pass through a passageway associated with drainage of a paranasal sinus or a Eustachian tube when the dilation member is in the non-expanded configuration. The bulbous tip is positioned at the distal end of the shaft. The bulbous tip is distal to the dilation member. The bulbous tip has a second outer cross-sectional dimension. The second outer cross-sectional dimension is larger than the first outer cross-sectional dimension. The bulbous tip is removably secured to the distal end of the shaft.

Abstract: Generally, abnormal pressures in the sinus cavity can have physiological effects due to stimulation or injury of various nerves that are in proximity to the sinus, including increased or decreased pressure on the nerves as well as extrusion of the nerves into the sinus cavities due to bony dehiscence. Methods and devices for alleviating disorders associated with the sinus cavities are described. Embodiments herein include diagnosing these disorders by occluding or restricting the sinus ostium and assessing the physiological effects caused by the occlusion/restriction and treating these disorders by navigating/directing a dilating device to the sinus ostium and dilating the sinus ostium. Other embodiments are directed to devices for maintaining the ostial opening.

Abstract: A dilation catheter includes a shaft and an expandable element. The shaft includes a proximal portion and a distal portion. The distal portion includes a tip and a bend. The tip is sized and configured to pass through an isthmus of a Eustachian tube (ET). The bend is proximal to the tip. The bend is formed at an angle configured to provide insertion of the tip into the isthmus of the ET via an ear canal associated with the ET. The expandable element is disposed at the distal portion of the shaft. The expandable element is configured to transition between a non-expanded state and an expanded state. The expandable element in the non-expanded state is configured for insertion into the ET via the isthmus. The expandable element in the expanded state is configured to dilate the ET.

Abstract: A device having a hub assembly and a lever coupled with the hub assembly is provided. The device includes a sheath coupled with the lever and extending from the hub assembly. The sheath has a surgical elevator with a surgical elevator edge along with a hypotube having an access hole. The device has a shaver blade assembly with an outer shaft having an outer blade and an inner blade within the outer blade. The outer shaft has a stop and an access hole near the outer and inner blades. The sheath partially surrounds the outer shaft and the lever moves between a first position and a second position. In the first position, the surgical elevator edge abuts the outer shaft stop and the outer shaft access hole aligns with the hypotube access hole. In the second position, the surgical elevator edge is spaced apart from the outer shaft stop.

Abstract: Variations of integral navigation controls may be used in conjunction with a medical instrument to provide navigation functions for an image guided surgery (IGS) system that is in communication with the integral navigation controls. In some variations, a medical instrument with integrated navigation wheels allows movement of a cursor of the IGS system along the x and y axis by scrolling the wheel, or allows selection, zooming, or other controls by combined clicking and/or scrolling of wheels, and may be sterilized or discarded along with the device. In some other variations, a control overlay may be temporarily attached to the medical instrument to provide additional controls, such as buttons or a pointing stick, and then removed and sterilized or discarded after a procedure. In each variation, inputs may be communicated via wire or wirelessly to an IGS system to provide navigation of images during a surgical procedure.

Abstract: A stent that is sleeved and radially expandable, and which in an expanded state provides a breathable, generally tubular structure sized and shaped for residence in a sinus or nasal cavity or passage, and in an unexpanded state has a cross-sectional diameter suitable for insertion into such cavity or passage. The sleeve limits expansion and outward pressure exerted by the stent and thereby can prevent or reduce the incidence of headache in patients, and can provide increased surface area for improved elution of chugs to nearby mucosal tissue.

Abstract: A method is used to manufacture a surgical instrument including a first tube, and a second tube. The first tube extends from a proximal first end portion to a distal first end portion. The second tube extends from a proximal second end portion to a distal second end portion. The second tube is positioned coaxially within the first tube with the distal second end portion positioned adjacent to the distal first end portion. The second tube defines a lumen. The sensor is secured proximal to the distal second end portion of the second tube. A die is engaged against a distal first end portion of the first tube while first tube rotates about its own longitudinal axis; and the die is simultaneously moved relative to the distal first end portion of the first tube along a predetermined path to form a predetermined shape.

Abstract: The present disclosure provides a bioresorbable foam closure device for trans-nasally closing an opening in a base of a skull. The closure device comprises a phase-separated polymer. The device includes a stem portion having a proximal end and a distal end, and a head portion at the distal end of the stem portion. The closure device is deformed from a free shape to a constricted shape, inserted through a nasal cavity and into the opening, and released to at least partially revert back to the free shape such that the stem portion fills the opening and the head portion abuts cranium and dura to secure the closure device in position and seal the opening.
