(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.

(19) The material comprises 3 main elements: the angioscope, the TV-monitoring assembly and the infusion system.
(20) The angioscopes are either rigid, composed of two groups of fibre optics (image and light transmission) or orientable and more complex.
Capillary
Definition:
(a.) Resembling a hair; fine; minute; very slender; having minute tubes or interspaces; having very small bore; as, the capillary vessels of animals and plants.
(a.) Pertaining to capillary tubes or vessels; as, capillary action.
(n.) A tube or vessel, extremely fine or minute.
(n.) A minute, thin-walled vessel; particularly one of the smallest blood vessels connecting arteries and veins, but used also for the smallest lymphatic and biliary vessels.
Example Sentences:
(1) Electronmicroscopical investigations have revealed that, under normal conditions, a minor vesicular transfer of intravenously injected peroxidase occurs across the endothelium in segments of arterioles, capillaries and venules, especially in arterioles with a diameter about 15-30 mu.
(2) During capillary growth when endothelial cells (EC) undergo extensive proliferation and migration and pericytes are scarce, hyaluronic acid (HA) levels are elevated.
(3) The capillary-adipocyte distances were shorter and the vascularization density was higher in old rats.
(4) Within the capillary-perfused mucosa and muscularis (between 50 and 2000 microns from the urothelial surface), concentrations decreased by 50% for each 500-microns distance.
(5) The kidney disease was characterized by diffuse beaded deposition of rat gammaglobulin along the glomerular capillaries and proteinuria.
(6) The glomerular capillary is part of the arterial system and is better perceived as a "hemiarteriole."
(7) Their levels in urine are a useful indicator of the integrity of membrane barriers of the kidney glomerular capillary wall.
(8) Lisinopril increases cardiac output, and decreases pulmonary capillary wedge pressure and mean arterial pressure in patients with congestive heart failure refractory to conventional treatment with digitalis and diuretics.
(9) Combined study of lungs of 85 foetuses and newborns of various gestational age and 8 newborns dying during the first month of life showed the lung surfactant (LS) system to develop in parallel with formation of respiratory parts and lung capillary network.
(10) The penetration coefficient, determined by the surface tension, contact angle and viscosity, is a measure of the ability of a liquid to penetrate into a capillary space, such as interproximal regions, gingival pockets and pores.
(11) It is suggested that intra-endothelial conduction of electrical signals from capillaries to the resistance vessels may be involved in the local regulation of blood flow in the intact heart.
(12) Whereas the tight junctions of endoneurial capillaries are known to prevent certain blood-borne substances from entering the endoneurium, it was not clear whether the permeability of the pulpal capillaries, which are distant from the nerve fibres, could affect the nerve fibre environment.
(13) The observations support the idea that the function of pericytes in the choriocapillaris, the major source of nutrition for the retinal photoreceptors, resides in their contractility, and that pericytes do not remove necrotic endothelium during capillary atrophy.
(14) Indirect methods to evaluate left ventricular function included the use of the Swan-Ganz catheter for pulmonary capillary wedge pressure measurement, systolic time intervals, and cardiac output.
