Abstract: Balloon catheters, coil assemblies, and methods for making the same. An example balloon catheter may include a coil assembly. The coil assembly may include a coil, a coating disposed on the coil, and a sheath disposed over the coil and the coating. A guidewire lumen may be defined by the coil assembly. An outer tube disposed over at least a portion of the coil assembly. A balloon may be coupled to the outer tube. An inflation lumen may be defined between the coil assembly and the outer tube.

Abstract: 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.
