摘要：A device (10) for enabling sequential dilation of a percutaneous tissue openingto successively larger opening sizes. The device (10) includes a first-elongated dilatorelement (11) having a forward end (13), an intermediate dilator body (14) and a tailsection (12) extending from shoulder structure (15) at the junction of the intermediate

body (14) and tail section (12). At least one additional elongated tubular dilator (20) isadapted for telescopic mounting over the first dilator element (11) and includes aforward end (25), intermediate body, rearward end and blocking member (26). Thisdilator (20) is tubular in construction and sized to fit snugly around the first dilatorelement (11) in telescoping manner. The blocking member (26) positioned at a rearwardend of the dilator (20) allows it to be seated in a forward-most position, in contact withthe shoulder structure (15) of the first dilator element (11). Additional dilators (21, 22) ofsuccessively larger diameters can be added to increase the extent of tissue dilation.Removal of the dilator device (10) is accomplished by grasping the tail section (12) andwithdrawing the system from within a sheath or cannula emplaced to link a patient to anextracorporeal circulatory system.
