Deployment of stents within bifurcated vessels

Abstract

Systems and methods for deploying stents within bifurcated vessels in a true pantaloons configuration (Kamat technique) are disclosed. A device including a balloon catheter and a stent surrounding the catheter is inserted into a bifurcated blood vessel. The catheter includes a first lumen configured to accept a first guide wire, which exits the device at a distal end. The device is advanced within a main branch using the first guide wire until it reaches the carina, thus causing the second guide wire to enter a second side branch. The second wire exits the device at a tapered edge of the catheter from under the stent. The stent may then be deployed within the main branch. The stent may then be splayed across the carina with kissing balloons and the procedure may be completed with the kissing balloon deployment of two stents accurately at the carina in each side branch.

Dependencies are inferred from the claim text.
