Aneurysm clip testing meter. 1980

M Dujovny, and A Perlin, and N Wackenhut, and L Leff, and N Kossovsky, and D Nelson

The force that a vascular clip exerts when it is applied to a vessel is a critical factor in its safe and proper use. Permanent occlusion effected in the obliteration of aneurysms requires clip closure forces great enough to resist sliping, yet low enough not to damage the neck of the aneurysm. The authors consider the need for a device that can readily measure clip closing forces just prior to pre-surgical sterilization (immediately prior to implantation), and an instrument that meets that need is presented.

D009493 Neurosurgery A surgical specialty concerned with the treatment of diseases and disorders of the brain, spinal cord, and peripheral and sympathetic nervous system. Neurosurgeries
D012044 Regression Analysis Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.

D000783 Aneurysm Pathological outpouching or sac-like dilatation in the wall of any blood vessel (ARTERIES or VEINS) or the heart (HEART ANEURYSM). It indicates a thin and weakened area in the wall which may later rupture. Aneurysms are classified by location, etiology, or other characteristics.
