Abstract: A medical device includes a scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the balloon by a process that includes inflating the delivery balloon during a diameter reduction to improve scaffold retention and maintaining an inflated balloon during the diameter reduction and prior and subsequent dwell periods.

Abstract: The present disclosure provides a catheter pump system including a catheter assembly having a proximal end and a distal end. The catheter assembly includes an elongate body extending between the proximal end and the distal end. The catheter body further includes a distal portion disposed at the distal end, said distal portion comprising a bent portion, said bent portion configured to enable a steering of said catheter assembly though an artery.

Abstract: A medical device includes a balloon expanded scaffold (or stent) crimped to a catheter having a balloon. The scaffold is crimped to the balloon by a process that includes using protective polymer sheaths or sheets during crimping, and resetting the sheaths or sheets during the crimping to avoid or minimize interference between the polymer material and scaffold struts as the scaffold is reduced in size. Balloon pressure is adjusted when the polymer material is reset.

Abstract: A medical device includes a balloon expanded scaffold crimped to a catheter having a balloon. The scaffold has a network of rings formed by struts connected at crowns and links connecting adjacent rings. The scaffold is crimped to the balloon by a process that includes using protective polymer sheaths or sheets during crimping, and adjusting the sheaths or sheets during the crimping to avoid or minimize interference between the polymer material and scaffold struts as the scaffold is reduced in size.

Abstract: Methods of reducing crimping damage to polymer and drug coating on a scaffold are disclosed. The methods include physically aging a coating including a coating polymer and drug mixture on a scaffold in a manner that takes into account the differing kinetics of aging, that is, the different temperature dependence of the aging rate of the polymer and drug.

Abstract: A process for crimping stents includes a multi-stage process producing a desired stent retention and crimped profile in a reduced amount of time. The process achieves results by utilizing particular combinations of heat and pressure during the crimping process, which was found to produce the desired results.

Abstract: A method of securely mounting a stent on a balloon of a catheter. The method generally includes crimping a stent on a balloon of a catheter at least one time, and positioning the balloon with the stent thereon within a polished bore of a mold formed at least in part of a metallic material. The balloon is pressurized and heated within the mold, or within a sheath, in two stages as the stent is restrained from radially expanding. The method may include crimping the stent onto the balloon one or two times during processing. The method increases retention of the stent on the balloon catheter following sterilization.
