  • Publication number: 20110015645
    Abstract: Systems and methods are provided for automatically forming an incision in a tympanic membrane of an ear and placing a tympanic membrane pressure equalization tube into the incision. The systems include a housing with a shaft extending therefrom. A mechanism is disposed within the housing. A distal end of the shaft is placed against a tympanic membrane, and the mechanism is triggered to causes the tympanic membrane to be automatically incised and dilated and a tympanic membrane pressure equalization tube to be placed in the dilated incision.

  • Publication number: 20110004057
    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.

  • Publication number: 20100168511
    Abstract: A method for dilating a stenotic region in an airway of a patient may include advancing a balloon catheter through the airway of the patient to position an inflatable balloon of the catheter within at least a portion of the stenotic region, maintaining a position of the catheter relative to the patient, and inflating the balloon of the catheter to dilate the stenotic region of the airway. A system for dilating a stenotic region in an airway of a patient may include a catheter shaft having an overall length of less than 70 cm, an inflatable balloon disposed along a distal portion of the catheter shaft, and a stylet.

  • Publication number: 20100121308
    Abstract: Devices and methods for delivering drugs and other therapeutic or diagnostic substances to desired locations within the bodies of human or non-human animal subjects. An implantable delivery device comprising a reservoir is initially attached to a deliver catheter or delivery tool and is introduced into the body and positioned at a desired site. A therapeutic or diagnostic substance is then introduced into the reservoir and the delivery catheter or deliver tool is then removed, leaving the implantable delivery device implanted within the body. The substance is then delivered from the reservoir at a rate that causes the desire diagnostic or therapeutic effect. Also provided are substance eluting stents that elute substance from a selected surface of the stent (e.g., the outer surface) but not from another surface of the stent (e.g., the inner surface).

  • Publication number: 20100076269
    Abstract: Systems and methods for treating paranasal sinuses in a head of a patient include, for example, forming an opening through a canine fossa into a maxillary paranasal sinus and performing a procedure such as a balloon catheter dilation of the maxillary sinus ostium. In some embodiments, one or more procedures other than a balloon dilation procedure may be performed. In some embodiments, a combination of balloon dilation and one or more other procedures may be performed. Various approaches involve employing medical devices to accomplish alternative treatment modalities as well as taking alternative routes to the interventional site.
