    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: Aspects herein relate to coating apparatus and methods for coating medical devices. In an embodiment, a coating system is included having a valve, a fluid supply reservoir in fluid communication with the valve, a reciprocating positive displacement pump in fluid communication with the valve, and a fluid applicator in fluid communication with the three-way valve. The valve can be configured to assume a first fluid transport state and a second fluid transport state, wherein the valve provides fluid communication between the fluid supply reservoir and the reciprocating positive displacement pump when in the first fluid transport state for filling of the reciprocating positive displacement pump, and wherein the valve provides fluid communication between the reciprocating positive displacement pump and the fluid applicator when in the second fluid transport state for applying a coating suspension to a medical device surface. Other embodiments are also included herein.

    Abstract: In an example, a scoring device is configured for retention of a catheter shaft. The scoring device incudes a proximal portion and a distal portion. A retention sleeve extends between the proximal and distal portions. The retention sleeve has a catheter socket configured to selectively receive and mechanically engage the catheter shaft. The scoring device includes a scoring tool coupled with the retention sleeve, for instance proximate to the distal portion. The scoring tool includes a balloon socket configured to selectively receive a balloon of the catheter shaft. The scoring tool includes one or more scoring elements extending around the balloon socket, the one or more scoring elements configured to provide localized scoring to vasculature.
