  • (15) The purpose of this study is to describe the use of angioscopes in flowing bloodstreams of animals and humans, to demonstrate the ability to precisely deliver laser energy to an intravascular target using visual guidance and to determine the information content and spatial content of angioscopy.
  • (16) For percutaneous CA the angioscope was introduced from the femoral artery through a 9F guiding catheter.
  • (17) A small caliber angioscope with an end capable of being propped up is then pushed within the lumen of the catheter.

Vessel


Definition:

  • (n.) A hollow or concave utensil for holding anything; a hollow receptacle of any kind, as a hogshead, a barrel, a firkin, a bottle, a kettle, a cup, a bowl, etc.
  • (n.) A general name for any hollow structure made to float upon the water for purposes of navigation; especially, one that is larger than a common rowboat; as, a war vessel; a passenger vessel.
  • (n.) Fig.: A person regarded as receiving or containing something; esp. (Script.), one into whom something is conceived as poured, or in whom something is stored for use; as, vessels of wrath or mercy.
  • (n.) Any tube or canal in which the blood or other fluids are contained, secreted, or circulated, as the arteries, veins, lymphatics, etc.
  • (n.) A continuous tube formed from superposed large cylindrical or prismatic cells (tracheae), which have lost their intervening partitions, and are usually marked with dots, pits, rings, or spirals by internal deposition of secondary membranes; a duct.
  • (v. t.) To put into a vessel.

Example Sentences:

  • (1) Arterial compliance of great vessels can be studied through the Doppler evaluation of pulsed wave velocity along the arterial tree.
  • (2) With aging, the blood vessel wall becomes hyperreactive--presumably because of an augmented vasoconstrictor and a reduced vasodilator responsiveness.
  • (3) Multiple overlapping thin 3D slab acquisition is presented as a magnitude contrast (time of flight) technique which combines advantages from multiple thin slice 2D and direct 3D volume acquisitions to obtain high-resolution cross-sectional images of vessel detail.
  • (4) In the course of the syndrome development blood vessel permeability was increased in the anterior chamber of the eye.
  • (5) Aside from these characteristic findings of HCC, it was important to reveal the following features for the diagnosis of well differentiated type of small HCC: variable thickening or distortion of trabecular structure in association with nuclear crowding, acinar formation, selective cytoplasmic accumulation of Mallory bodies, nuclear abnormalities consisting of thickening of nucleolus, hepatic cords in close contact with bile ducts or blood vessels, and hepatocytes growing in a fibrous environment.
