LOCKING STILETTO FOR EXTRACTION OF ENDOCARDIAL ELECTRODES OF ELECTROSTIMULATOR (VERSIONS) Russian patent published in 2016 - IPC A61B17/50 A61N1/05 

FIELD: medical equipment.

SUBSTANCE: invention relates to medical equipment. Locking stiletto for extraction of endocardial electrodes of cardiostimulator has elongated cylindrical housing (1), one end (2) of which is configured to receive electrode (4), and other (3) - to grip. Stiletto consists of movable (5) and fixed (6) relative electrode parts, obtained by cutting housing (1) with an inclined plane passing through base of cylindrical housing (1). Parts (5, 6) of stiletto are configured to change cross sectional area of housing (1) by means of displacement relative to each other in adjacent inner surfaces upon applying to movable part (5) a pulling force in direction of longitudinal axis (7) of electrodes (4). Adjacent inner surfaces are stepped and inclined.

EFFECT: higher reliability of fixation of locking stiletto in electrode due to stable mechanical locking of components of stiletto relative to electrode due to increased cross sectional area when parts of stiletto are moved relative to each other.
