A tinnitus method and device for providing relief to a person suffering from the disturbing effects of tinnitus is described. The method can be implemented entirely in software to spectrally modify an audio signal in accordance with a predetermined masking algorithm which modifies the intensity of the audio signal at selected frequencies. A predetermined masking algorithm is described which provides intermittent masking of the tinnitus wherein, at a comfortable listening level, during peaks of the audio signal the tinnitus is completely obscured, whereas during troughs the perception of the tinnitus occasionally emerges. In practice it has been found that such intermittent masking provides an immediate sense of relief, control and relaxation for the person, whilst enabling sufficient perception of the tinnitus for habituation and long term treatment to occur. Advantageously the predetermined masking algorithm is specifically tailored to the audiometric configuration of the person. For example, the masking algorithm may be partly tailored to the hearing loss characteristic of the person. A tinnitus rehabilitation device used in conjunction with a personal sound reproducing system is also described.

Methods, systems and devices are described for temporarily or permanently evacuating stagnating air from a diseased lung area, typically for the purpose of treating COPD. Evacuation is accomplished by displacing the stagnant CO₂-rich air with a readily diffusible gas using a transluminal indwelling catheter specially configured to remain anchored in the targeted area for long term treatment without supervision. Appropriate elevated positive gas pressure in the targeted area is then regulated via the catheter and a pneumatic control unit to force under positive pressure effusion of the diffusible gas out of the area into neighboring areas while inhibiting infusion of other gases thus effecting a gradual gas volume decrease and deflation of the targeted area.

Systems and methods screen and/or treat disorders of the body using neurostimulation.

The invention relates to a method for the treatment of an oestrogen-dependent proliferative disorder of the uterus such as endometriosis and uterine fibroids in a patient, by administering an aromatase inhibitor to the patient intravaginally. This achieves high local levels of aromatase inhibitor Locally, and therefore avoids some of the adverse reactions that are observed when aromatase inhibitors are delivered orally. Further, intravaginal delivery allows inhibition of the local lesional production without significantly affecting the circulating levels which have been produced by the ovaries. This results in minimal side-effects and will allow for longer term treatment than current therapies.
