    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: A uniaxially compressed dosage form manufactured by three-dimensional printing that preserves the predetermined internal architecture of the dosage form while producing an improved surface finish. The compression compacts the dosage form, eliminating at least some of the void space that remains at the end of conventional three-dimensional printing. Surface finish obtained as a result of the uniaxial compression process can be essentially equal to that obtained from conventional tablet pressing. Additionally, the internal structure or spatial variation of composition of the dosage form is preserved during the pressing operation, with geometric shrinkage occurring mostly in the direction of the axis of pressing. Further, as a result of compression, a greater quantity of API can be packed into a given final volume of dosage form.

    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.
