  • METHODS FOR IMPROVING STENT RETENTION ON A BALLOON CATHETER
    Publication number: 20170119564
    Abstract: A method of crimping a stent on a balloon of a catheter assembly is provided. A polymeric stent is disposed over a balloon in an inflated configuration. The stent is crimped over the inflated balloon to a reduced crimped configuration so that the stent is secured onto the balloon. The balloon wall membrane is wedged or pinched between the strut elements of the stent for increasing the retention of the stent on the balloon.

  • LOCATION-BASED USER DISAMBIGUATION
    Publication number: 20160164850
    Abstract: Embodiments are directed to validating the identity of a user. In one scenario, a computer system determines that a login account has been created for a user, where the creation includes generation of a first identifier for the user based on a user's determined location at the time of account creation. The computer system next receives a login attempt from the user that includes a second, different identifier and one or more login credentials. The computer system then determines the location from which the login attempt was received and, using the second identifier and the determined login location, identifies the user account corresponding to the user. The computer system further authenticates the user upon determining that the second identifier and login location match the first identifier.
