    摘要： Methods and devices for providing temporary placement of a filter in a blood vessel are disclosed. A filter delivery system in accordance with one exemplary embodiment of the present invention includes a catheter having an elongate shaft and a tubular member disposed within a shaft lumen defined by the elongate shaft. The elongate shaft also includes a proximal end, a distal end, and a wall defining the shaft lumen. The tubular member has a first end fixed to the wall of the elongate shaft, and a second end disposed within the shaft lumen. The tubular member defines a guidewire lumen that is in fluid communication with a distal guidewire port defined by the second end of the tubular member. The catheter also includes a proximal guidewire port extending through the wall of the elongate shaft. A filter may be disposed within a distal portion of the shaft lumen. A distal end of a guidewire is fixed to the filter. The guidewire preferably extends through the distal guidewire port, the guidewire lumen, and the proximal guidewire port.

    摘要： 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.

    摘要： A stent delivery system to facilitate introduction and placement of a stent, including a catheter having an expandable distal portion constructed and arranged for expanding the outer diameter of the catheter from a contracted state to an expanded state: a stent positioned around the distal portion of the catheter having a contracted condition and being expandable to an expanded condition, and being sized in the contracted condition to closely surround the catheter in the contracted state, the expandable distal portion of the catheter including a balloon within which there is included on the catheter shaft at least one body of a diameter larger than the catheter shaft to which the stent and balloon are fitted, as by crimping, for holding the stent in place until it is released therefrom by expansion of the balloon.

    摘要： An assembly and a method to deliver and deploy and inflation expandable stent is described. The assembly has a catheter with an annular collar is coaxially located on the catheter distal end. An expandable balloon, in a contracted state, is coaxially mounted over the collar at the catheter distal end. A stent, in a reduced configuration, is coaxially mounted on the balloon and conformed to the catheter and collar. At least one cup is coaxially mounted on the catheter distal end. The cup and collar are cooperate to retain the end portion of the reduced stent on the catheter. The balloon is inflated to expand the stent and release the stent from the cup or cups. The cup can be axially spaced from the collar. The cup can be fixed to the catheter or can be freely sliding on the catheter. The cup can overlie at least a portion of the collar. The collar can be shaped as a single member with the catheter.
