Abstract: Intravascular imaging catheters and methods for making and using intravascular imaging catheters are disclosed. An example intravascular imaging catheter may include an elongate catheter shaft having a distal end region and a proximal region. The distal end region may include a side port. An imaging core may be disposed within the elongate catheter shaft. The imaging core may include an imaging device configured to be slidable within the elongate catheter shaft and through the side port.

Abstract: An apparatus for treating a total occlusion in a blood vessel may include a self-orienting device including an elongate shaft and an inflatable orienting element. The shaft includes an inflation lumen having a first noncircular shape and a working lumen having a second noncircular shape. The inflatable orienting element includes first and second inflatable members extending laterally from the shaft. An outer diameter of the shaft is 0.045 inches or less, a cross-sectional area of the first noncircular cross-sectional shape is at least 0.00013 square inches, and a cross-sectional area of the second noncircular cross-sectional shape is at least 0.00056 square inches. The shaft may include a distal tail extending distally from the inflatable orienting element, the distal tail being at least 15 millimeters long. The shaft may include a plurality of first apertures communicating with the working lumen and disposed in the distal tail.

Abstract: A recanalization catheter for facilitating reentry into a lumen of a vessel having an occlusion therein from a subintimal space in a wall of the vessel. The recanalization catheter includes a catheter shaft extending distally from a hub. The catheter shaft defines a guidewire lumen extending therethrough. First and second inflatable balloon members are disposed on a distal end region of the catheter shaft. The catheter shaft includes an inflation lumen in fluid communication with the first and second inflatable balloon members. A lateral opening which is in communication with the guidewire lumen opens to an exterior of the catheter shaft between the first and second inflatable balloon members on a first side of the catheter shaft. The catheter shaft also includes an imaging lumen extending through the catheter shaft configured to receive an IVUS imaging device therein.

Abstract: Intravascular imaging devices and methods for making and using intravascular imaging devices are disclosed. An example intravascular imaging device may include a catheter shaft configured to be disposed within a blood vessel. The catheter shaft may have an imaging window region and an imaging lumen. The imaging lumen may be configured to accommodate and imaging assembly therein. A distal tip member may be coupled to the catheter shaft. The distal tip member may have a guidewire lumen formed therein. The imaging window region and the distal tip member may axially overlap.
