Abstract:
An ablation assembly comprising:a driveshaft having a proximal end and a distal end; a material removal instrument coupled to the distal end of the driveshaft; a tube having a proximal end and a distal end, wherein the distal end is coupled to the proximal end of the driveshaft; a rotational drive assembly movable from a first position forward along a path of motion; and an elastomeric plug coupled to the rotational drive assembly for rotation therewith, wherein the proximal end of the tube is insertable into the elastomeric plug to create an interference fit with the elastomeric plug thereby coupling the driveshaft to the rotational drive assembly; wherein the interference fit created between the elastomeric plug and the tube has a strength that is less than the strength by which the material removal instrument is coupled to the distal end of the driveshaft.
