Device and Method for Sampling Bodily Fluid for Medical Analytes in Ultra Low Concentrations

A method of sampling bodily fluid for analyzing for the presence of a medical analyte in a patient, the method comprising:

• deploying a trapping device into a biological cavity or blood vessel of a patient;
• after a period of time 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.

A method for selectively obtaining and analyzing a constituent of a patient's bodily fluid, the method comprising:

• providing a device for collecting the constituent from the bodily fluid, the device comprising a material that has an affinity to the constituent;
• deploying the device into a location to contact the bodily fluid for a predetermined period, wherein a quantity of the constituent adheres to the material;
• and thereafter
• removing the device from the location.

A viral particle trapping device for sampling a viral particle, comprising:

• a structural substrate;
• and
• a plurality of antibodies capable of binding with the viral particle affixed to the structural substrate;
• wherein the trapping device is dimensioned and adapted for placement in a biological cavity or vessel in a patient, which cavity or vessel contains a biological fluid, the trapping device being configured to trap at least a portion of a medical analyte present in the biological fluid.
