Abstract
A balloon catheter has a central tube that is configured to both structurally support and inflate a balloon membrane. The central tube has a lumen and sidewall inflation ports that provide a path for inflating the balloon. The lumen of the central tube is obstructed by a distal end piece, nose piece, or other structure to prevent fluid from exiting a distal end of the central tube. The central tube is configured such that, during inflation, inflation media is allowed to pass through an elongated shaft of the catheter, into a proximal open end of the central tube, and through the inflation ports into the balloon. The central tube can slide longitudinally in relation to the shaft to longitudinally elongate and/or truncate the balloon.
