    摘要: Implantable medical devices (IMDS) having anti-infective properties are described. Anti-infective agents are disposed in, on, or about at least a portion of a surface of the medical device. The anti-infective agents are disposed in or on a vehicle, which may be in the form of a coating layer or covering. The vehicle may be biodegradable so that, over time, the anti-infective agent is removed from a tissue location into which the device is implanted, reducing the likelihood that microorganisms resistant to the anti-infective agent will develop. IMDs having an anti-infective agent and an anti-activity agent disposed therein, thereabout, or thereon are also described. The anti-activity agent interferes with the activity of the anti-infective agent, may be released from a surface at the IMD at a time when activity of the anti-infective agent is no longer desired, and may reduce the likelihood that microorganisms resistant to the anti-infective agent will develop.

    摘要: Activation of an enzyme in a bodily fluid is detected based on the amount of cleavage of a substrate for the enzyme. The substrate is tagged with two fluorescent dyes—a donor and an acceptor. The tagged substrate is presented to the bodily fluid. A device emits energy at a first wavelength into the bodily fluid, and detects energy at second and third wavelengths emitted by the dyes in response to the energy at the first wavelength. Prior to enzymatic cleavage of the substrate, the acceptor emits energy at the third wavelength in response to energy at the second wavelength received through fluorescent resonant energy transfer (FRET) from the donor. After enzymatic cleavage of the substrate, the donor emits energy at the second wavelength. The device can determine the concentration of activated enzyme within the bodily fluid based on the relative intensities of energy, at the second and third wavelengths.
