Abstract: In an assembly of a balloon mounted on a catheter and a stent mounted over the deflated balloon, the balloon is provided with a fugitive plasticizer before the stent is crimped over the balloon. The fugitive plasticizer can soften the balloon surface so that molding of the balloon surface to conform to the crimped stent occurs. The fugitive plasticizer is removed before the assembly is used.

Abstract: A system/assembly for delivery and deployment of an inflation expandable stent within a vessel, comprising a catheter having proximal and distal ends; a stent, inflation expandable from a delivery diameter to a deployment diameter, such that the delivery diameter is reduced from the deployment diameter for conforming the stent to the catheter, such that the stent, in its delivery diameter, is coaxially mounted on the catheter near the catheter distal end; an expandable inflation means coaxially mounted on the catheter axially within the stent, for expansion of the stent from the delivery diameter to the deployment diameter upon application of fluid deployment pressure to the inflation means; and a securement component coaxially mounted on the catheter, axially within the expandable inflation means, the securement component designed and adapted to provide a securement pressure to the stent in the delivery diameter to maintain the stent in position on the catheter during delivery to the deployment site.

Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an elongate shaft including a first tubular member and a second tubular member. A balloon may be coupled to the shaft. A first member may be coupled to the first tubular member and positioned within the balloon. A second member may be coupled to the first tubular member and positioned within the balloon. A medical implant may be coupled to the shaft and positioned adjacent to the balloon.

Abstract: A balloon catheter stent deployment system is disclosed wherein a balloon catheter is provided and a tubular stent is crimped onto a distal portion of the balloon with a distal end of the stent in close proximity to a point where the distal end of the balloon is attached to the inner tube of the catheter. A proximal section of the balloon extending from a proximal end of the stent to a point where the proximal end of the balloon is attached to the outer shaft of the catheter remains uncovered by the stent and, has a larger uninflated outer diameter than the crimped stent. Thus, in some embodiments, the proximal section of the balloon provides a protective cone for the proximal end of the stent to help resist frictional forces from disengaging the stent from the balloon in the event the balloon catheter and stent are withdrawn back into a guide catheter during a procedure.

Abstract: A balloon catheter may comprise a primary inflation balloon and a secondary inflation balloon located to one side of the primary inflation balloon. The secondary balloon comprises a first portion and a second portion, the first portion located closer to the primary balloon. The second portion has a greater size than the first portion, and a portion of the second portion extends outwardly beyond the first portion and overhangs the first portion. In some embodiments, a cross-sectional shape of the secondary balloon in an inflated state comprises a mushroom shape.

Abstract: An assembly for delivery and deployment of an inflation expandable stent within a vessel is comprised of a catheter, an inflation expandable stent, an expandable balloon, and a securement means such as a corrugated tube component or an expandable tube component. The tube component is mounted on the inner shaft beneath the balloon and provides increased securement to the stent in a reduced delivery diameter to maintain the stent on the catheter during delivery to the deployment site. The tube component is adhered to the inner shaft and has a plurality of ribs or is fluid expandable to no more than the delivery diameter and may be comprised of more than one separately inflatable pouch expandable to provide the stent with a substrate seat with increased friction and to decrease the slack in stent recoil crimping. The assembly is used in a method for delivering and deploying a stent, and also adds safety when loading/crimping the stent onto a balloon.
