摘要： Apparatus, systems, and methods for percutaneous valve replacement and/or augmentation are provided. The apparatus includes a valve having a valve frame, a valve leaflet coupled to the valve frame, and a leaflet transition member coupled to the valve leaflet. The valve leaflet and leaflet transition member can transition from a first position where the valve leaflet and leaflet frame are at least partially outside a lumen of the valve frame to a second position where the valve leaflet and the leaflet transition member are within the lumen of the valve frame.

摘要： A venous valve device provides antegrade blood flow in venous vessels of the body having dysfunctional valves; it is formed in situ from autologous vein conduit not having a valve present locally. An overlap region is formed by attaching two opposing walls of the vein together in a generally axial direction forming two tubular regions. One region provides antegrade blood flow and the other region provides a sinus cavity that is filled during the initiation of retrograde blood flow. A valve cusp is formed by attaching vessel wall together forming a commissure that extends between the two overlap regions. A single valve cusp moves toward the sinus cavity to allow antegrade blood flow and moves away from the sinus cavity to block retrograde blood flow. The venous valve can also be formed from biological tissue from an autologous, heterologous, or other tissue source and implanted interpositionally at the site of valvular incompetancy.

摘要： A distal protection and delivery system is used to collect and remove embolic debris in the blood vessel. The system includes a guidewire, a filter assembly, and a distal introducer. The distal introducer can be positioned on a distal end of an introducer catheter or an angioplasty catheter or other interventional catheter. The guidewire has a small ferrule or locking mechanism fixed to it that does not affect the flexibility, torqueability, or trackability in comparison to standard guidewires. The introducer containing the filter assembly is advanced over the guidewire to a site distal to the lesion. Upon retraction of the guidewire proximally, the ferrule latches with an ejector latch of the filter assembly. Either advancement of the guidewire distally or retraction of the distal introducer proximally allows the filter assembly to be ejected from the distal introducer and into the blood vessel.
