摘要： The invention provides methods and apparatus for determining physiological characteristics of body lumens, such as the length of a blood vessel. According to one exemplary method, the distance between a first target location and a second target location within a lumen are measured by aligning a first marker on a first elongate member disposed within a lumen with the first target location. A second marker on a second elongate member disposed within the lumen is aligned with the second target location. The distance between the first and second markers is then measured, and the measured distance corresponds to the distance between the first and second target locations.

摘要： The invention provides apparatus for determining physiological characteristics of body lumens, such as the length of a blood vessel. A catheter allows measurements of the distance between a first target location and a second target location within a lumen by aligning a first marker on a first elongate member disposed within a lumen with the first target location. A second marker on a second elongate member disposed within the lumen is aligned with the second target location. The distance between the first and second markers is then directly measured from spaced-apart calibration marks along the second member, and the measured distance corresponds to the distance between the first and second target locations.

摘要： Three-dimensional structures providing a plurality of separate interpenetrating, three-dimensional domains or channels or flowpaths, each of said domains or channels or flowpaths being a closed system of connected porosity or permeability and each of said domains or channels or flowpaths being interpenetrating within said structure, have been prepared. These structures are prepared from porous permeable precursor materials having a single three-dimensional domain or channel or flowpath as described above. Suitable precursor materials are provided by the abundant porous carbonate skeletal material of marine life, e.g. the coral Porites skeletal aragonite. For example, by coating the surfaces of such materials with a liquid material capable of being cured or set to a solid, followed by curing or setting and dissolution, e.g. chemical etching, of the coated skeletal material, there is produced a three-dimensional structure in accordance with this invention possessing two separate interpenetrating, three-dimensional domains or channels or flowpaths defined by the residual cured or set coating material. The resulting structure of this invention can be adapted such that a fluid can be applied to one side or face of the structure to flow into and out of such structure via only one of said channels or flowpaths and when so adapted can be employed in apparatus for the treatment or handling of one or more of the fluid streams flowing therethrough.
