摘要： A percutaneous transluminal angioplasty device, comprising an elongated catheter, an interventional device operably coupled to the proximal end of the catheter, a filter operably coupled to the distal end of the catheter, the filter movable between a collapsed and deployed position, and an actuator wire for deploying the collapsing the filter. At least a portion of the actuator wire extends within the catheter. The filter comprises a filter chassis comprising a movable collar a fixed collar and a tubular braided scaffolding coupled between the movable collar and the fixed collar. The filter chassis also comprises a filter membrane coupled to the tubular braided scaffolding.

摘要： A percutaneous transluminal angioplasty device having an embolic filter mounted to the catheter shaft at a location distal to the angioplasty balloon and downstream from the blockage to capture embolic particles that may be set loose into the blood stream as the angioplasty procedure is performed. The embolic filter is normally collapsed against the catheter shaft to facilitate introduction and withdrawal of the device to and from the operative site. Once the angioplasty balloon is properly positioned, however, means operatively associated with the embolic filter are actuated to erect the filter to operatively position a filter mesh across the lumen of the vessel.

摘要： A percutaneous transluminal angioplasty device includes a catheter defining one or more lumens. A filter is coupled to the catheter adjacent a distal end of the catheter, and the filter is movable between an unexpanded and expanded configuration via a filter activation wire that extends through a lumen. An expandable balloon is coupled to the catheter proximally of the filter, and a stent is disposed over at least a portion of the balloon. To deploy the stent to a target site, the filter is first moved into its expanded position via the filter activation wire. Then, the stent is expanded, and the balloon is inflated to expand the stent further radially. The balloon is then deflated, the filter is contracted, and the catheter, balloon, and filter are removed from the body.

摘要： Implementations described herein comprise expandable stents configured to maintain a substantially constant length between a collapsed position and a deployed position having a plurality of spring members and a plurality of biasable couplings connecting adjacent spring members. Each spring member includes a plurality of integrally connected wave members formed in a ring shape, each wave member has a plurality of curved segments having a plurality of substantially straight segments disposed therebetween. The plurality of biasable couplings are adapted to elongate upon movement of the stent from the collapsed position to the deployed position to proportionally compensate for the decrease in amplitude of the plurality of wave members of the plurality of spring members such that the stent maintains a substantially constant length.

摘要： A percutaneous transluminal angioplasty device includes an embolic filter mounted to the catheter shaft at a location distal to the angioplasty balloon. Thus the filter can be down-stream from the blockage and can be properly positioned to capture embolic particles that may be set loose into the blood stream as the angioplasty procedure can be performed. The embolic filter can be normally un-deployed against the catheter shaft to facilitate introduction and withdrawal of the device to and from the operative site. Once the angioplasty balloon can be properly positioned, however, means operatively associated with the embolic filter can be actuated to erect the filter to position a filter mesh across the lumen of the vessel.
