Abstract: An anchored dilator includes a push tube having proximal and distal push tube portions. A dilator tip is coupled with the distal push tube portion and is configured for selectable coupling with a catheter. The dilator tip includes an anchor cuff having a cuff interface. The anchor cuff is configured to transition between a shuttle configuration having a shuttle profile and an anchored configuration having an anchored profile larger than the shuttle profile. A cuff operator assembly is configured to transition the anchor cuff between the anchored and shuttle configurations. The cuff operator assembly includes a cuff operator movably coupled with the dilator tip, and an operator shaft coupled with the cuff operator. The operator shaft extends toward the proximal push tube portion. Actuation of the cuff operator with the operator shaft transitions the anchor cuff between the shuttle configuration and the anchored configuration.

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.
