摘要： A medical simulator for enabling demonstration, trial and test of insertion of torqueable elongated members into small body passages that branch from main passages is disclosed. Such torqueable members may be guide wires or catheters which are constructed to cause the distal tip to turn or twist in response to a corresponding motion applied by the operator to a proximal portion of the device.

摘要： An x-ray apparatus uses an x-ray tube which is pivoted about a pivot axis to provide scanning of an x-ray beam. The pivot axis passes essentially through the center of the focal spot on the target surface of the anode of the tube, is essentially perpendicular to the anode-cathode axis, and is essentially parallel to a film plane defined by the x-ray film. The scanning of the x-ray beam by pivoting the x-ray tube results in improved systems for standard radiography, linear tomography, and large-scale angiography. In standard radiography and large scale angiography systems, moving primary and secondary slots synchronized with the pivoting of the x-ray tube provide efficient removal of secondary radiation. In linear tomography systems, the object and film are moved synchronously with the pivoting of the x-ray tube, and primary and secondary slots which are stationary remove secondary radiation.

摘要： A catheter for insertion into the human body and made of a thermoplastic tubing, is preformed to a desired shape by heating it above its free form temperature and allowing it to cool while held in that shape. To hold the catheter in position for such forming .Iadd.and/or for storage before use.Iaddend., a forming board having a catheter receiving groove of the desired shape is used. .[.The.]. .Iadd.In the form of the invention shown, the cross-sectional shape of this groove is wider at the bottom and narrower at the open top where it becomes a part of the board so as to hold the catheter in place during the forming and storage and to allow the catheter to be easily removed thereafter. This .Iadd.particular form of .Iaddend.forming board is made by vacuum forming a sheet of thermosetting plastic .Iadd.or thermoplastic material .Iaddend.over a solid, non-heat responsive, master representation of the exact longitudinal shape of the final preformed catheter. The cross-sectional shape of the master is the negative of the desired cross-section of the final forming board groove. When the catheter has been .[.so.]. preformed .Iadd.and lies in one of the forming board grooves, .Iaddend.it and its forming board are packaged in a sealed plastic bag which is, like the catheter and the forming board, permeable to sterilizing gas. The resulting package is gas claved and stored in this sealed condition until ready for use. The catheter is removed from the sealed package and .Iadd.from .Iaddend.the forming board immediately before insertion into the body. When it has served its purpose, it .[.is.]. .Iadd.can be .Iaddend.removed from the body, cleaned, positioned back into .[.the.]. .Iadd.a .Iaddend.forming board, preformed with heat when necessary, placed in another sealed film container, and resterilized for storage until it is again needed.
