| set-up | 1. The arrangement of teeth on a trial denture base. 2. A procedure in dental case analysis involving cutting off and repositioning of teeth in the desired positions on a plaster cast. (05 Mar 2000) |
| ear, low-set | A minor anomaly involving an ear situated down below its normal location. Technically, the ear is low-set when the helix (of the ear) meets the cranium at a level below that of a horizontal plane through both inner canthi (the inside corners of the eyes). The presence of 2 or more minor anomalies in a child increases the probability that the child has a major malformation. (12 Dec 1998) |
| first-set rejection | Allograft transplantation between two organisms not previously sensitised to the graft tissue. Necrosis of the graft usually occurs within 10 days of transplantation. (05 Mar 2000) |
| learning set | A readiness or predisposition to learn developed from previous learning experiences, as when an organism learns to solve each successive problem (of equal or increasing difficulty) in fewer trials. (05 Mar 2000) |
| low-set ear | An ear positionned below its normal location. Classified as a minor anomaly. Technically, the ear is low-set when the helix (of the ear) meets the cranium at a level below that of a horizontal plane through both inner canthi (the inside corners of the eyes). The presence of 2 or more minor anomalies in a child increases the probability that the child has a major malformation. (12 Dec 1998) |
| acorn-tipped catheter | A catheter used in ureteropyelography to occlude the ureteral orifice and prevent backflow from the ureter during and following the injection of an opaque medium. (05 Mar 2000) |
| angiography catheter | A thin-walled tube suitable for percutaneous puncture and powered injection of contrast media for radiography; catheter diameter is measured on the French scale. (05 Mar 2000) |
| balloon catheter | A catheter used in arterial embolectomy or to float into the pulmonary artery. (05 Mar 2000) |
| balloon-tip catheter | A tube with a balloon at its tip that can be inflated or deflated without removal after installation; the balloon may be inflated to facilitate passage of the tube through a blood vessel (propelled by the bloodstream) or to occlude the vessel in which the tube alone would allow free flow; such catheter's are used to enter the pulmonary artery to facilitate haemodynamic measurements or to enter arteries and then remove them while inflated to withdraw clots (embolectomy catheter). See: Swan-Ganz catheter. Synonym: Fogarty catheter. (05 Mar 2000) |
| bicoudate catheter | Catheter bicoude, an elbowed catheter with a double bend. Origin: bi + Fr. Coude, bent (05 Mar 2000) |
| Bozeman-Fritsch catheter | A slightly curved double-channel uterine catheter with several openings at the tip. (05 Mar 2000) |
| Braasch catheter | A bulb-tipped catheter used for dilation and calibration. (05 Mar 2000) |
| brush catheter | A ureteral catheter with a finely bristled brush tip that is endoscopically passed into the ureter or renal pelvis and by gentle to-and-fro movement brushes cells from the surface of suspected tumours. (05 Mar 2000) |
| cardiac catheter | <cardiology> A catheter that can be passed into the heart through a vein or artery, to withdraw samples of blood, measure pressures within the heart's chambers or great vessels, and inject contrast media. It is used mainly in the diagnosis and evaluation of congenital, rheumatic, and coronary artery lesions and to evaluate systolic and diastolic cardiac function. Synonym: cardiac catheter.
