INSTRUMENT DELIVERY DEVICES, SYSTEMS, AND METHODS TO EXTEND THROUGH A THROMBUS

Abstract:

A method may include coupling a first delivery device to a catheter assembly, which may include a catheter dwelling within vasculature of a patient. The first delivery device may include a first tubular instrument. In response to the first tubular instrument being in a distal position, a distal surface of the first tubular instrument may be disposed at a first distance beyond the distal tip of the catheter. The method may include coupling a second delivery device to the catheter assembly after uncoupling the first delivery device from the catheter assembly. The second delivery device may include a second tubular instrument. In response to the second tubular instrument being in the distal position, a distal surface of the second tubular instrument may be disposed at a second distance beyond the distal tip of the catheter. The second distance may be greater than the first distance.
