Abstract: A balloon catheter includes a catheter shaft extending between proximal and distal end portions along a shaft axis. The catheter shaft includes an inflation lumen, and at least one inflation port in communication with the inflation lumen. A balloon assembly is coupled with the catheter shaft and in communication with the at least one inflation port. The balloon assembly includes a balloon membrane having a balloon body, a balloon proximal nose and a balloon distal nose coupled with the catheter shaft. An interlaced jacket is coupled with the balloon membrane, the interlaced jacket includes interlaced filaments extending at diverging angles relative to the shaft axis.
