Abstract: The disclosure provides insertion tools and articles that facilitate entry of a medical device, such as a balloon catheter, into the body, and that can provide advantages in terms of balloon insertion, safety, and drug delivery. The insertion tool includes a tubular portion that accommodates a balloon portion of a balloon catheter, and one or more separation margin(s) in the wall of the tubular portion or one or more split(s) in the tubular wall. The insertion tool also includes a proximal tab that extends from a second lengthwise half having a portion at an angle skew to the lengthwise axis, or that is in the form of a solid article comprising a concave surface that is fastened to an outer surface of the second lengthwise half of the tubular portion; or first and second tabs that extend from first and second lengthwise halves of the tubular portion, respectively.

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.
