Definitions
- catheter technologies require complex, microscopic manufacturing processes that make it hard to provide exactly reproducible readings from catheter to 25 catheter.
- the invention provides methods and apparatus to reference or normalize optical measurements, by removing or accounting for background factors and artifacts, such as motion artifacts.
- the invention provides methods for referencing factors due to equipment that can be addressed prior to use of an optical catheter, as well as factors due to the local measurement conditions in a patient that arise during use. Some of these factors are the same from patient to patient, such as the general nature of blood, and others vary from patient to patient, such as the specific constituents of each patient's blood.
- the known environment can be a new reflecting apparatus as described herein including a hollow well and a reflective internal surface.
- the known environment can also be a liquid having known optical characteristics, such as scatter and absorbance.
- the liquid can include styrene divinyl/benzene cross- linked copolymer beads suspended in an ultrapure aqueous solution.
- the new apparatus can be used individually or in conjunction with each other.
- the invention features methods of obtaining reference measurements of the various components of the materials through which electromagnetic radiation travels from a catheter to the tissue, into the tissue, and back to the catheter to enhance the ability to discriminate measurements from the target.
- all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention, suitable methods and materials are described below. All publications, patent applications, patents, and other references mentioned herein are incorporated by reference in their entirety. In case of conflict, the present specification, including definitions, will control.
- the materials, methods, and examples are illustrative only and not intended to be limiting.
- the guide catheter 50 includes a distal end 54 and a proximal end 56.
- the window 52 is positioned between the proximal and distal ends so that the window 52 is within the aorta or vena cava when the guide catheter is fully in place.
