20140277053 | SUBINTIMAL RE-ENTRY CATHETER WITH SHAPE CONTROLLED BALLOON - A recanalization catheter for facilitating re-entry into a lumen of a blood vessel from a subintimal space. The catheter includes an inflatable balloon mounted on a distal end region of the catheter shaft of the catheter. The catheter shaft includes a guidewire lumen having a distal opening and a lateral opening in a distal region of the catheter shaft proximal of the distal opening, and an inflation lumen in fluid communication with the balloon. The balloon is configured to be inflated in the subintimal space to a first inflation state at inflation pressures below a threshold inflation pressure to orient the lateral opening toward the lumen of the blood vessel, and inflated to a second inflation state at inflation pressures above the threshold inflation pressure. The catheter includes means for retaining the balloon in the first inflation state at pressures below the threshold inflation pressure. | 09-18-2014 |
