Abstract:
A method of inserting a stent includes inserting a unitary, monolithic catheter assembly into a cardiac artery. The catheter assembly includes a body having a proximal end and a distal end, a distal balloon mounted on the distal end, and a proximal balloon mounted on the body, proximally of the distal balloon. A balloon expandable stent is mounted on the distal balloon. The method further includes the steps of advancing the catheter assembly to a blockage in the artery until the distal balloon and the stent both extend across the blockage; inflating the distal balloon and expanding the stent; deflating the distal balloon; advancing the catheter body distally until the proximal balloon extends within the stent; expanding the proximal balloon to post-dilate the stent; deflating the proximal balloon; and withdrawing the catheter body from the artery.
