  • Patent number: 9610428
    Abstract: Devices, systems and methods wherein a dilator, such as a balloon or other expandable member, is positionable within the frontal sinus ostium and adjacent frontal recess and useable to dilate the frontal sinus ostium and substantially all of the frontal sinus recess without requiring repositioning and repeated re-expansion of the dilator. One balloon catheter device of the invention comprises a catheter body that is less than about 50 cm in length (and in some embodiments less than 25 cm in length and a semi-compliant or non-compliant balloon on the catheter body. The balloon may have a working length of about 12 mm to about 30 mm and a width at its widest point when fully inflated of about 2 mm to about 7 mm. Such balloon may be constructed to withstand inflation pressures of about 12 atmospheres. In some embodiments, the dilator is advanced through or over a guide (e.g., guidewire or guide catheter) that has a preformed shape.

  • Patent number: 9603506
    Abstract: Devices and methods for visually confirming the positioning of a distal end portion of an illuminating device placed within a patient include inserting a distal end portion of an illuminating device internally into a patient, emitting light from the distal end portion of the illuminating device, observing transillumination resulting from the light emitted from the distal end portion of the illuminating device that occurs on an external surface of the patient, and correlating the location of the observed transillumination on the external surface of the patient with an internal location of the patient that underlies the location of observed transillumination, to confirm positioning of the distal end portion of the illuminating device.

  • Patent number: 9604041
    Abstract: An apparatus comprises a body and a conduit. The body comprises an absorbent material. The conduit is in fluid communication with the body. The conduit has a suction opening positioned within the absorbent material. The conduit is operable to draw fluid away from the absorbent material. The apparatus may be positioned within the posterior choana or the nasopharynx of a patient using a deployment instrument. The apparatus may prevent fluids from draining from the nasal cavity into the patient's throat. In some instances, the apparatus is used as a plug during a sinus irrigation procedure to prevent irrigation fluid from traveling down the patient's throat.

  • Patent number: 9457175
    Abstract: A set of sinus balloon catheters are provided for treating a patient's paranasal sinus system, including dilating prepared openings, and natural ostia and ducts and excising sinus cavities. These include a balloon catheter with a bend placing a distal segment at 90° to a proximal segment and a balloon catheter which is substantially straight. The catheters have sufficient stiffness and column strength that the balloon carrying distal segment of the catheter can be pushed into the prepared opening, natural ostium or duct, or sinus to be excised. The catheters have appropriate inflated working diameters and appropriate outer diameters with the balloon deflated that will enable the catheter to be pushed into the respective prepared opening, natural ostium or duct, or sinus cavity to be excised. The methods use the balloon catheters to dilate prepared openings to selected parts of the sinus system, to dilate natural ostia and ducts of the sinus system, and/or to dilate sinus cavities to remove them.

  • Patent number: 9433437
    Abstract: Fluid communication may be improved for an ethmoid sinus by installing a port or wick in the wall of the ethmoid sinus to provide a fluid passageway across the wall of the ethmoid sinus. Fluid communication for an ethmoid sinus may also be improved by inflating a balloon in a retrobullar space, remodeling the posterior wall of the ethmoid bulla to expand the transition area in the retrobullar space. In addition, a wall defining the retrobullar space may be pierced to provide a passageway for fluid communication.

  • Patent number: 9433763
    Abstract: An apparatus comprises an absorbent body, a non-permeable feature, and a port feature. The absorbent body comprises a wicking feature. The non-permeable feature is coupled with the absorbent body. The non-permeable feature and at least a portion of the absorbent body are configured to fit in an opening in a paranasal sinus wall. The port feature extends through the absorbent body. The port feature defines a lumen. The wicking feature extends outwardly relative to the port lumen. During installation of the apparatus, the non-permeable feature is positioned in an opening in the paranasal sinus wall. The absorbent body is oriented such that the wicking feature is in contact with mucosal tissue in a sinus cavity defined by the paranasal sinus wall. A proximal portion of the absorbent body is positioned outside the paranasal sinus wall.

  • Patent number: 9399121
    Abstract: A dilation catheter device and system for dilating an opening in a paranasal sinus and/or other passageways within the ear, nose or throat is disclosed. A dilation catheter device and system is constructed in a manner that facilitates ease of use by the operator and, in at least some cases, allows the dilation procedure to be performed by a single operator. Additionally, the dilation catheter device and system may be useable in conjunction with an endoscope and/or a fluoroscope to provide for easy manipulation and positioning of the devices and real time visualization of the entire procedure or selected portions thereof. In some embodiments, shaft markers are disposed on a shaft of the dilation catheter and have a light color to contrast with a dark color of the dilation catheter shaft. The high contrast between the markers and catheter shaft allows for easy viewing of the markers in low light and operation conditions.
