    摘要: Trapping devices and methods are provided for capturing a medical analyte, in blood or another biological fluid. The device may include a structural substrate and a binding agent, such as an antibody, affixed to the structural substrate, wherein the binding agent is capable of binding or attaching with a medical analyte, such as a viral particle, and the device is configured for placement in a biological cavity or vessel (containing a biological fluid) in a patient. The trapping device, which may be in a twisted coil shape, is configured to trap at least some of the medical analyte, such a viral particle, present in the biological fluid. The method may include deploying a trapping device into the patient's blood vessel; after a period following the deployment, removing the trapping device from the biological cavity or blood vessel; and then analyzing the trapping device for the presence of the medical analyte.
