1. A balloon catheter for deploying a prosthetic heart valve through balloon inflation, comprising:
an inner shaft defining a guidewire lumen;
an outer shaft surrounding the inner shaft defining an inflation lumen between the outer shaft and the inner shaft;
a distal portion at a distal end of the outer shaft;
a balloon disposed at the distal portion such that fluid delivered to the balloon via the inflation lumen causes the balloon to inflate; and
a distal first retention bumper secured to the inner shaft, the distal first retention bumper including a spoked first portion including a first hub and first spokes extending directly radially outward from the first hub and defining first flow passages therebetween and a first tapered portion including first tapered spokes aligning with the first spokes.
