The present invention provides a method for the formation of a medical device that comprises a therapeutic agent and a release region, which regulates the rate at which the therapeutic agent is released from the medical device. The method comprises providing a precursor region that comprises a polymer composition comprising two or more microphase separated polymer domains that are immiscible with one another, and forming said release region by a process that comprises applying an orienting field comprising an electric field, a magnetic field, a mechanical shear field, or a solvent gradient field, or a combination of two or more fields to said precursor region, wherein said field or combination of fields changes the spatial orientation of the microphase separated polymer domains within the release region. The electric, magnetic, mechanical shear or solvent gradient field is of sufficient strength to change the spatial orientation of the microphase separated domains. Moreover, the spatial orientation of the immiscible microphase separated polymer domains affects the rate of release of the therapeutic agent from the medical device.

The disclosed methods and devices incorporate a novel expandable bubble portion which provides superior fidelity to a listener while minimizing listener fatigue. The expandable bubble portion may be expanded through the transmission of low frequency audio signals or the pumping of a gas to the expandable bubble portion. In addition, embodiments of the acoustic device may be adapted to consistently and comfortably fit to any ear, providing for a variable, impedance matching acoustic seal to both the tympanic membrane and the audio transducer, respectively, while isolating the sound-vibration chamber within the driven bubble. This reduces the effect of gross audio transducer vibration excursions on the tympanic membrane and transmits the audio content in a manner which allows the ear to utilize its full inherent capabilities.

Stable blend compositions composed of mixtures of polysiloxane(s) and organic polymer(s) are claimed. These polymer blends are white and opaque indicating the presence of phase separation on the micron scale. Such blends can be stored for long periods of time (years) without exhibiting evidence of macroscopic phase separation. These stable blends are achieved without substantial crosslinking as evidenced by the fact that the polymer blend is readily dissolved in a suitable organic solvent for molecular weight characterization. The stable blends of the present invention have particular utility as fouling release coatings for marine applications.

An ear device having a bubble for placement approximate a user's ear canal and capable of inflation and deflation is disclosed. An inflation tube for delivering inflating air to the bubble during inflation of the bubble and an inflation source, such as a diaphonic valve, cause the bubble to extend automatically into the user's ear canal during inflation and retract from the user's ear canal during deflation. The bubble is substantially cylindrical and is comprised of a plurality of adjacently adjoined inflatable chambers. The bubble may also comprise at least one non-inflatable section interspersed therein. Where the ear device is used to convey sound to the user's ear, the device includes a sound tube positioned within the cylindrical bubble. At least one resilient member attached to a portion of the bubble, which may be a non-inflatable section of the bubble, is used to retract the bubble automatically. The ear device, equipped with a cerumen removing mechanism, may be used to clean a user's ear canal as well.
