摘要：
A system may include a catheter and a support cannula within the catheter. The catheter may include a tapered tip and a body extending proximally therefrom. The catheter tip may have a smaller inner diameter than the catheter body. The support cannula may include a tip disposed within the catheter tip such that the support cannula tip does not extend distally beyond the catheter distal end and a support segment extending proximally from the support cannula tip and disposed within the catheter body such that the catheter body remains in a non-stretched configuration. An outer diameter of the cannula tip may correspond to the inner diameter of the catheter tip. An outer diameter of the support segment may correspond to the inner diameter of the catheter body. The support segment may extend proximally to at least a proximal end of a perforated segment of the catheter body.
