Patent ID: 11510798

Abstract:
For deploying a stent at a coronary ostium, an integrated intravascular ultrasound (IVUS) ostial stent delivery apparatus can include a balloon catheter and an elongate shaft defining (1) a longitudinal inflation lumen and (2) a longitudinal IVUS lumen. A balloon can be located at and about the distal shaft portion and inflated with the inflation lumen. The shaft further defines a longitudinal guidewire lumen, extending at least through the distal shaft portion underlaying the balloon for at least a length of the balloon along the shaft. The IVUS lumen can include removable IVUS ultrasound imaging transducer with a signal conduit to external processing and display componentry. The imaging can help ensure proper stent location before placement and deployment, or for post-placement and stent deployment confirmation, without requiring removal of the stent delivery device to deploy a separate IVUS imaging probe.
