Boosting Catheter and Related Systems and Methods

摘要

The various embodiments herein relate to a boosting catheter for positioning through a conventional guiding catheter into the vasculature of a patient, the boosting catheter having a distal tubular member and a proximal elongated shaft coupled to the distal tubular member.

主权项

1. A method of using a boosting catheter in combination with a standard guiding catheter to perform a procedure at a predetermined location within the vasculature of a patient, the method comprising:
positioning the standard guiding catheter into a target vessel in the patient; inserting the boosting catheter into the standard guiding catheter, the boosting catheter comprising:
(a) a distal tube comprising a tubular wall and a tube lumen defined within the tube by the tubular wall; and(b) a proximal shaft operably coupled to a proximal portion of the distal tube, the proximal shaft comprising a shaft lumen defined in the proximal shaft, wherein the proximal shaft is configured to extend distally into a portion of the tube lumen such that the shaft lumen extends distally past a proximal end of the distal tube; urging the boosting catheter distally through the standard guiding catheter such that a distal portion of the distal tube extends distally out of the distal end of the standard guiding cathether; and performing a procedure through the boosting cathether and standard guiding catheter.
