Abstract
A method for securely mounting an endovascular stent (2) to a balloon catheter (3, 5) involves the use of a loading device (1) that includes a longitudinal sheath having an opening (10) into which the balloon (5) is inserted. The stent is supported slidably along the outside of the sheath so that it can be slid along the sheath into a position coaxially about the balloon. The stent then is released into stable and secure engagement with the balloon (5) by withdrawing the sheath from between the stent and the balloon. The method may be used in conjunction with a stent that is elastically deformable to a diameter enabling it to be placed about the balloon and then permitted to tighten, elastically, into secure engagement with the balloon, gradually and uniformly. The sheath may be in the form of longitudinal elements (7) connected at one end to a support (6) and having free opposite ends.
