  • Publication number: 20100217296
    Abstract: A method is disclosed for clearing effusion from an ear. The method may include applying liquid to an ear canal, which is proximal to a perforated tympanic membrane, which is proximal to a middle ear containing effusion, applying an ear device to seal and pressurize the liquid inside the ear canal, the ear device regulating the amount of pressure inside the ear canal, and inducing a Eustachian tube, which is distal to the middle ear, to open, which causes the fluid to displace the effusion into the Eustachian tube.

  • Publication number: 20100198135
    Abstract: A system and method for use in iontophoretic anesthesia of a tympanic membrane are disclosed. The system generally includes an earplug and an electrode device. The earplug includes at least one sealing member for sealing the earplug in an ear canal. The sealing member includes microholes which vent fluid above a certain pressure threshold. A headset may connect the earplug to a second earplug. The method involves using the system on a human or animal subject.

  • 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.

  • Publication number: 20090163848
    Abstract: A method of anesthetizing a tympanic membrane of an ear of a patient using iontophoresis is disclosed. The method involves delivering an anesthetizing drug solution to an ear canal of the patient's ear, wherein the drug solution includes an anesthetic and a buffer, and wherein the drug solution has a pH in the range of about 6.5 to about 7.5; and applying an amount of current to the drug solution, wherein the amount of applied current is increased at a rate of less than about 0.5 milliamp per second until a maximum current is achieved.

  • Publication number: 20080262468
    Abstract: Systems and methods for treating a patient having a head with a first ear and a second ear, function by mounting a support structure to the head of the patient; aligning the support structure with a target tissue in an ear canal of the first ear; stabilizing the support structure relative to the target tissue by injecting a material into the canal and hardening the material; and actuating a device while the device is supported by the support system so that the device therapeutically remodels the target tissue of the first ear.

  • Publication number: 20080262509
    Abstract: Systems and methods for treating a patient having a head with a first ear and a second ear function by mounting a support system to the head of the patient so that the support system is aligned with a target tissue of the first ear; applying a therapeutic agent to the first ear by energizing an iontophoresis electrode supported by the support system; and actuating a device while the device is supported by the support system so that the device therapeutically remodels the target tissue of the first ear.

  • Publication number: 20050143758
    Abstract: Anastomosis devices, tools and methods of performing sutureless anastomosis. Anastomosis devices are provided for fixing a first conduit to a second conduit in an anastomosis, where the conduits are joined by interfacing their inner walls together. The conduit which is loaded on the anastomosis device may be mounted in such a way that the internal wall of the conduit does not make contact with the anastomosis device.
