Abstract: Stent delivery systems and methods for making and using stent delivery systems are disclosed. An example stent delivery system may include an inner member. A sheath may be disposed about the inner member. The sheath may include a proximal portion and a distal portion. The proximal portion of the sheath may define a first inner diameter and the distal portion of the sheath may define a second inner diameter greater than the first inner diameter. A bumper may be disposed about the inner member. The bumper may have an outer diameter that is greater than the first inner diameter of the sheath and that is less than the second inner diameter of the sheath.

Abstract: An implantable medical endoprosthesis delivery system includes a sheath, a catheter at least partially surrounded by the sheath, and a bumper disposed between the sheath and the catheter. The bumper has at least some freedom of movement with respect to the catheter, and the sheath, catheter, and bumper are configured so that an implantable medical endoprosthesis can be disposed between the sheath and the catheter.

Abstract: A system for reducing the diameter of a stent comprises a stent contracting assembly and a fluid source. The assembly comprises a plurality of contracting members that define a diameter reduction chamber for receiving a stent. When the chamber is in a pre-reduction configuration the stent has a first diameter and when the chamber is in a reduced configuration the stent has a second diameter. The second diameter is less than the first diameter. The fluid source is in fluid communication with the chamber and is constructed and arranged to inject a fluid therein. The fluid forms a fluid bearing between the contracting members and the stent which prevents the contracting members from contacting the stent in the reduced diameter configuration.

Abstract: A system and method for enrolling participants in a retirement plan simplifies election decisions necessary to enroll in the retirement plan and encourages retirement savings through use of the retirement plan. An enrollment form is provided to participants, the enrollment form includes a convenience election option whereby if the participant selects the convenience election option then does not specify the allocation of investments into funds. The enrollment form is processed and if the convenience election option is selected the participants contributions are allocated into funds based on the expected retirement age of the participant.
