    摘要: In one embodiment, the present disclosure provides a biodegradable, self-powered medical device for preventing or reducing reperfusion injury, comprising a galvanic cell, the galvanic cell comprising: a first biodegradable electrode member; and a second biodegradable electrode member comprising a biodegradable conductive polymer and an electrode-releasable therapeutic agent, wherein the galvanic cell generates an electric force sufficient to cause the electrode-releasable therapeutic agent to be released from the biodegradable conductive polymer and elute to a target location. The device may further include a reservoir material containing a burst-release therapeutic agent.

    摘要: An intravascular filter for a vessel includes a non-biodegradable apical hub and non-biodegradable struts extending generally distally from the hub. The struts extend radially outward from a longitudinal axis of the hub. The distal ends of the struts exert an expansile force against an interior of the vessel. One or more struts includes one or more time-degrading connectors along its length, which can be formed from a biodegradable element made from a fixation material. Prior to degradation, the fixation material rigidly connects a proximal section to a distal section of the respective strut. After degradation, the fixation material is dissolved or softened, and reveals a link that has a strong resistance to longitudinal movement of the distal section with respect to the proximal section and may have a weak resistance to rotational movement of the distal section with respect to the proximal section, such as a pair of interlocked loops.
