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： Implantable medical devices and treatment methods are provided, particularly for use in the bladder. The device is configured for retention in the bladder for at least a portion of the drug delivery period and includes at least one biodegradable component such that following a biodegradation at a selected time, the retention function is lost and the device or portions thereof are resorbed and/or excreted. The method may include deploying into the bladder of a patient a device having a device structure housing a drug formulation comprising at a drug; releasing drug from the device structure into the bladder; and then, changing the composition of urine in the bladder, e.g., by altering the pH, to trigger degradation of at least part of the device structure to enable the device structure or parts thereof to be excreted from the bladder.

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： Reservoir-based medical devices are provided. In one embodiment, the medical device comprises a substrate; at least two discrete, microfabricated reservoirs provided in spaced positions across at least one surface of the substrate; discrete reservoir caps covering the at least two reservoirs; and control circuitry for selectively disintegrating the reservoir caps to open the reservoirs. The reservoirs of the device can include a diagnostic reagent or other molecules useful in medical diagnostics. In one embodiment, the reservoir cap comprises an anode and the control circuitry comprises a cathode and a power source for creating an electric potential between the cathode and the anode. Application of the electric potential causes the reservoir cap to disintegrate, thereby opening the reservoir.
