    摘要: A method is provided for local controlled delivery of a drug to the seminal vesicle, the prostate, the ejaculatory duct, or the vas deferens of a patient in need of treatment. In one embodiment, the method includes implanting a resorbable drug delivery device within the seminal vesicle, the prostate, the ejaculatory duct, or the vas deferens of the patient. The drug delivery device may include an elastic device body housing at least one drug reservoir which contains at least one drug. In a preferred embodiment, the method further includes releasing the drug from the device in a controlled manner to, typically directly to, the seminal vesicle, the prostate, the ejaculatory duct, or the vas deferens.

    摘要: Intravesical devices are provided that are wholly deployable within the bladder of a patient in need of treatment and are well tolerated by the patient. The device may include an elastic body having a retention shape having (i) dimensions that provide intravesical mobility and that prevent voiding of the medical device through the urethra, and (ii) dimensions, buoyancy, or both, that exclude the medical device from entering the orifices of the ureters. The elastic body may exert a maximum acting force less than 1 N when compressed to a shape with a maximum dimension in any dimension of 3 cm. The device may include a drug for controlled release within the bladder, for treatment of the bladder or a regional tissue. Methods of treatment are also provided that include selecting a patient in need of treatment in the bladder where tolerability of the treatment is a primary concern.

    摘要: The present invention provides systems, devices, and related methods, involving electrochemical actuation. In some cases, application of a voltage or current to a system or device of the invention may generate a volumetric or dimensional change, which may produce mechanical work. For example, at least a portion of the system may be constructed and arranged to be displaced from a first orientation to a second orientation. Systems such as these may be useful in various applications, including pumps (e.g., infusion pumps) and drug delivery devices, for example.

    摘要: Microchip devices are provided that include a substrate; a plurality of reservoirs in the substrate, each reservoir defining an internal volume; and a reservoir cap positioned on or in each of the reservoirs bounding the internal volume from an external environment, the reservoir cap being formed of a material that undergoes a phase change upon heating, wherein the internal volume can communicate with the external environment upon heating said reservoir cap to cause said reservoir cap to undergo a phase change and rupture.
