Abstract
A crimping tool for crimping a stented heart valve comprises a housing having a front wall and a back wall, a compression assembly disposed between the front wall and the back wall and including a stent receiving chamber therewithin for receiving a stented heart valve, and a delivery device holder slidably coupled to the front wall of the housing. The compression assembly is movable between an uncrimped position and a crimped position to reduce the diameter of the stented heart valve.
Claims10
A crimping tool comprising:
- a housing having a front wall and a back wall;
- a drive wheel movably positioned within the housing, the drive wheel including an actuation lever for moving the wheel between a first position and a second position;
- a plurality of bars operably coupled to the drive wheel and having a proximal end and a distal end, the distal end of the bars including a chamfered leading edge and an opposing planar surface and the proximal end of the bars including first and second legs forming a proximal opening therebetween;
- a chamber defined by the planar surfaces at the distal ends of the bars, the chamber being reducible in size from a first enlarged size to a second reduced size as the actuation lever moves from the first position to the second position;
- and
- a delivery device holder mounted on the front wall, the delivery device holder comprising a sliding plate slidably coupled to the front wall via at least one engagement member that extends from the front wall through a corresponding horizontal slot of the sliding plate.
