1. A boosting catheter comprising:
- (a) a distal tube comprising a tubular wall, a tube lumen defined within the tube by the tubular wall, and a proximal opening in fluid communication with the tube lumen, wherein the proximal opening is configured to allow a medical device to be positioned therethrough; and
(b) a proximal shaft operably coupled to a proximal portion of the distal tube, the proximal shaft comprising;
(i) a shaft lumen defined in the proximal shaft;
(ii) a first elongate member disposed within the shaft lumen, the first elongate member configured to extend distally into a first portion of the tubular wall; and
(iii) a second elongate member disposed within the shaft lumen, the second elongate member configured to extend distally into a second portion of the tubular wall,wherein the proximal shaft is configured to extend distally into a portion of the distal tube such that the shaft lumen extends distally past a proximal end of the distal tube.
